  USES=sudo has been added into ports, to allow depending on a
  different sudo flavor. Ports depending on sudo were updated
  to use and introduced USES.

  You can update make.conf to use sssd version of sudo with:

        DEFAULT_VERSIONS+=sudo=sssd

AUTHOR: python@FreeBSD.org

  PYTHON_EXT_SUFFIX has been renamed to PYTHON_TAG due to semantic
  ambiguity between existing ports usage and PEP 3147 and PEP 3149's
  specifications. Especially with Python 3.13's free-threaded mode,
  the tags between bytecode and compiled extension modules do not
  necessarily match. See python.mk for details.

  setuptools has been removed as a RUN_DEPENDS for USE_PYTHON=distutils
  ports, except for those operating under Python 2. If your port
  needs setuptools to run, you can add it back to RUN_DEPENDS, but
  keep in mind that this practice is deprecated and discouraged in
  the greater Python ecosystem.

  setuptools includes a module, pkg_resources, that historically
  has been used as a runtime API for "finding, introspecting,
  activating and using installed Python distributions." These
  functions have been superseded by the importlib family and the
  packaging package.

  setuptools also includes their own copy of distutils, which is
  not present in the base Python distribution starting in 3.12. The
  use of distutils primitives directly in consumers is also discouraged
  and deprecated.

AUTHOR: jhale@FreeBSD.org

  TEST_DEPENDS support has been added to Mk/Uses/qt.mk.

  If a component defined by USE_QT is only needed for regession tests,
  it can be added to TEST_DEPENDS buy suffixing it with ':test'.

  For example:
      USES=	qt:5
      USE_QT=	testlib:test

      Will add devel/qt5-testlib to TEST_DEPENDS

AUTHOR: yasu@FreeBSD.org

  3 new variables are defined if you add 'USES=samba' in Makefile.

  * SAMBA_TALLOC_PORT
  * SAMBA_TDB_PORT
  * SAMBA_TEVENT_PORT

  They are intended to be used by ports that works with Samba to
  specify proper version of talloc, tdb and/or tevent as dependency
  such as bellow.

      LIB_DEPENDS=	ibtalloc.so:${SAMBA_TALLOC_PORT} \
			libtdb.so:${SAMBA_TDB_PORT} \
			libtevent.so:${SAMBA_TEVENT_PORT}
      USES=		samba:env

  You need not use them if port just depends on talloc, tdb and/or
  tevent and it has nothing to do with Samba.

20250203:
AUTHOR: yasu@FreeBSD.org

  Following legacy variables are removed from Mk/Uses/samba.mk

  * SAMBAPORT
  * SAMBAINCLUDES
  * SAMBALIBS

  And ones below should be used instead.

  * SAMBA_PORT
  * SAMBA_INCLUDEDIR
  * SAMBA_LIBDIR

  Convert bsd.java.mk to USES

  The following features have been added or changed:
  - Instead of USE_JAVA use USES=java. This defaults to
    USES=java:build,run if NO_BUILD is undefined. Else it defaults to
    USES=java:run
  - Instead of USE_ANT=yes use USES=java:ant which also implies
    USES=java:build
  - Instead of JAVA_BUILD=yes use USES=java:build. Does not imply run or
    extract
  - Instead of JAVA_EXTRACT=yes use USES=java:extract does not imply
    build or run
  - Instead of JAVA_RUN=yes use USES=java:run does not imply extract or
    build
  - Instead of USE_JAVA=<version> use USES=java and JAVA_VERSION=<version>

20241231:
AUTHOR: bofh@FreeBSD.org

  Converted remaining bsd.ocaml.mk to Uses/ocaml.mk

  - Instead of USE_OCAML=yes use USES=ocaml. If empty USES=ocaml implies
    build and run
  - Instead of USE_OCAMLFIND_PLIST use USES=ocaml:findplist which also
    implies USES=ocaml:findlib
  - Instead of USE_OCAML_CAMLP4 use USES=ocaml:camlp4
  - Instead of USE_OCAML_FINDLIB use USES=ocaml:findlib
  - Instead of USE_OCAML_LDCONFIG use USES=ocaml:ldconfig
  - Instead of USE_OCAML_WASH use USES=ocaml:wash
  - Instead of NO_OCAML_BUILDDEPENDS use USES=ocaml:run
  - Instead of NO_OCAML_RUNDDEPENDS use USES=ocaml:build
  - Instead of USE_OCAML_TK use USES=ocaml:tk which actually implies
    USES=ocaml:tkbuild and USES=ocaml:tkrun
  - Instead of NO_OCAMLTK_BUILDDEPENDS use USES=ocaml:tkrun
  - Instead of NO_OCAMLTK_RUNDEPENDS use USES=ocaml:tkbuild
  - USES=ocaml:dune remains unchanged
  - Prepare to add/remove keywords easily

AUTHOR: flo@FreeBSD.org

  A new variable DBD_MYSQL has been introduced and should be used to depend
  on the correct version of p5-DBD-mysql. Versions >= 5.000 removed support
  for MariaDB. DBD_MYSQL will check which MYSQL_FLAVOUR is used and set the
  correct version as a dependency. For this to work, ports need to add mysql
  to USES.

20240408:
AUTHOR: makc@FreeBSD.org

  USES=cmake now supports `indirect' argument. This argument adds cmake binary
  to the BUILD_DEPENDS and and exposes CMAKE_ARGS and some other helpers, but
  does not run cmake in the configure step. cmake:indirect is intended
  primarily for ports which use meson or pep517 for build.

20240229:
AUTHOR: tijl@FreeBSD.org

  A new command SETENVI that clears the environment and a new variable
  WRK_ENV that contains a basic environment to use with SETENVI have
  been added.
  Ports that run (parts of) the upstream build system directly using
  commands like "${SETENV} ${MAKE_ENV} ${MAKE_CMD} ..." should change
  that to "${SETENVI} ${WRK_ENV} ${MAKE_ENV} ${MAKE_CMD} ...".  This way
  the build system runs with a clean environment without interference
  from the user environment or ports framework environment.  Ports can
  add extra environment variables to WRK_ENV similar to CONFIGURE_ENV,
  MAKE_ENV, TEST_ENV, and so on, but WRK_ENV is used in all targets
  while the latter are target-specific.

  MAN[1-8LN]PREFIX variable has been removed from the framework, use PREFIX
  directly.

20230929:
AUTHOR: sunpoet@FreeBSD.org

  USE_PYTHON=cryptography{,_build,_test} has been added to the ports tree.
  20230722 entry is obsoleted now. All existing USES=pycryptography* have
  been converted to USE_PYTHON=cryptography{,_build,_test} in PR 273727.

  Usage:
    USE_PYTHON=cryptography_build adds security/py-cryptography to BUILD_DEPENDS
    USE_PYTHON=cryptography adds security/py-cryptography to RUN_DEPENDS
    USE_PYTHON=cryptography_test adds security/py-cryptography to TEST_DEPENDS

20230823:
AUTHOR: tcberner@FreeBSD.org

  USES=llvm.mk now supports 'export' (default) and 'noexport' arguments.
  When export is set, CC, CXX and CPP will be set to the path corresponding
  to the chosen llvm-version.

20230821:
AUTHOR: jhale@FreeBSD.org

  A new uses 'ebur128' has been added to transparently depend on the
  proper variant of 'rust' or 'legacy' depending on the default version
  set by the user.

  Usage:	USES=ebur128:ARGS
  Valid ARGS:	<none>, build, lib, run, test
    <none>:	(default) same as lib
    build:	add BUILD_DEPENDS
    lib:	add LIB_DEPENDS
    run:	add RUN_DEPENDS
    test:	add TEST_DEPENDS

  If you prefer not to use rust, add the following to your make.conf:

	DEFAULT_VERSIONS+=ebur128=legacy

20230728:
AUTHOR: andrew@tao11.riddles.org.uk, fuz@FreeBSD.org

  A new uses 'guile' has been added to transparently depend on the
  proper variant of guile depending on the default version set by the
  user and the demands of the port.

  See Mk/Uses/guile.mk for in-depth documentation.

20230722:
AUTHOR: tcberner@FreeBSD.org

  A new uses 'pycryptography' has been added to transparently depend on the
  proper variant of 'rust' or 'legacy' depending on the default version set
  by the user.

  Supported arguments: <none>,build,run
  Passing no arguments (<none>) is equivalent to passing both build and run.

  Usage:
	USES=pycryptography:build
		-> adds a BUILD_DEPENDS only
	USES=pycryptography:run
		-> adds a RUN_DEPENDS only
	USES=pycryptography:test
		-> adds a TEST_DEPENDS only
	USES=pycryptography:build,run   or   USES=pycryptography
		-> adds a BUILD_ and RUN_DEPENDS

20230712:
AUTHOR: zirias@FreeBSD.org

  USE_GITLAB has been changed to allow fetching by tag name. This was done by
  removing the GL_COMMIT variable and introducing GL_TAGNAME instead.

  Similar to USE_GITHUB/GH_TAGNAME, you can still use a commit hash with
  GL_TAGNAME (the full 40-character hash is required for that). If not
  specified, GL_TAGNAME defaults to DISTVERSIONFULL.

  Note fetching by tag name might not work on gitlab installations running
  very old versions; in that case, you must still specify a commit hash.

  For now, GL_COMMIT is still recognized but deprecated, using it will issue
  a warning in developer mode.

20230712:
AUTHOR: 0mp@FreeBSD.org

  Two new targets are now available: fetch-url-recursive-list
  and fetch-urlall-recursive-list. They are the recursive variants
  of the well-established targets fetch-url-list and fetch-urlall-list,
  which allow for listing the complete URLs of DISTFILES and PATCHFILES
  of a port. The recursive variants add the URLs of the port's dependencies
  to the output.

20230430:
AUTHOR: zirias@FreeBSD.org

  USES=magick has been updated based on flavorized ports.

  A new argument 'x11' is available to specifically depend on the flavor
  with X11 support. Fallback to DEFAULT_VERSIONS now happens
  independently for the version (currently 6 or 7) and the flavor
  (currently x11 or nox11).

  Only use arguments for version or flavor if your port really requires
  it. Also, there is no need to add options for selecting the -nox11
  flavor any more, as the user setting in DEFAULT_VERSIONS will be
  honored.

20230111:
AUTHOR: vishwin@FreeBSD.org

  USE_PYTHON=pep517 has been added to facilitate building using the
  new format.

  USE_PYTHON=pep517 takes no arguments. Operation is similar to
  USE_PYTHON=distutils, although the build backend specified in
  pyproject.toml shall be specified in BUILD_DEPENDS.

  A usage guide and implementation primer is available at:
        https://wiki.freebsd.org/Python/PEP-517

20221217:
AUTHOR: tcberner@FreeBSD.org

  USES=llvm has been added to more easily depend on llvm.

  USES=llvm supports two kinds of arguments:

  * mode
	<none>:	defaults to build
	build:	add a BUILD_DEPENDS on chosen llvm-port
	run:	add a RUN_DEPENDS on chosen llvm-port
	lib:	add a LIB_DEPENDS on chosen llvm-port

  * version
	<none>:		defaults to ${LLVM_DEFAULT}
	number:		use explicitly the specified version
	min=number:	use specified min if ${LLVM_DEFAULT} is lower
	max=number:	use specified max if ${LLVM_DEFAULT} is higher

  An example usage might be:
	USES=	llvm
  or
	USES=	llvm:13,build
  or
	USES=	llvm:min=14,lib

  The following variables are exposed to be used in the ports tree at the moment:
	* LLVM_VERSION	version chosen from the arguments to llvm.mk
	* LLVM_PORT	chosen llvm port
	* LLVM_CONFIG	llvm-config of the chosen port
	* LLVM_LIBLLVM	libLLVM.so of the chosen port
	* LLVM_PREFIX	installation prefix of the chosen port

AUTHOR: bapt@FreeBSD.org
  3 new features are available now: PIE, RELRO, BIND_NOW, each port can
  specify the inability to support any via <feature>_UNSAFE

  All 3 are off by default, the intent is to activate following the freebsd
  base activation of the same features.

  End users can activate/deactivate globally via WITH_/WITHOUT_ <feature>

20221014:
AUTHOR: adamw@FreeBSD.org

  USES=luajit has been added to support a unified luajit version. The
  default here is luajit-devel, which should be the right version for
  nearly everybody.

  luajit-openresty is a drop-in replacement for anything that luajit-devel
  works in, though not necessarily the other way around. If a program uses
  the openresty-specific API then you will need USES=luajit:luajit-openresty.

  The standard USES for most ports:
    USES=luajit

  For anything that requires the openresty API:
    USES=luajit:luajit-openresty

20220911:
AUTHOR: zirias@FreeBSD.org

  kde.mk, qt.mk and pyqt.mk now use a colon for component suffixes

  Suffixes for build, run and test (for pyqt) dependencies used an underscore
  previously. This was not in line with most other USES, using a colon for
  that purpose.

  So if you previously had for example

	USE_QT=	buildtools_build

  replace it with

	USE_QT= buildtools:build

20220907:
AUTHOR: se@FreeBSD.org

  The convention of a WWW: line at the end of each port's pkg-descr file
  has been changed to a WWW= definition in the port's Makefile. All ports
  have been converted to follow this new scheme.

  The portlint and portfmt ports will be updated, but may erroneously flag
  the new convention as incorrect until the new versions have been installed.

20220826:
AUTHOR: tcberner@FreeBSD.org

  A new Uses for 'vala' has been added.

  To depend on libvala, use
  	USES=vala:lib
  to only add a build-time dependency, use
  	USES=vala:build

20220821:
AUTHOR: kde@FreeBSD.org

  qt.mk now supports both Qt 5 and Qt 6.

  To make use of Qt6 write:

        USES=qt:6
        USE_QT=list of Qt6 components

  Please take a look at qt.mk to see the available components.

20220722:
AUTHOR: portmgr@FreeBSD.org

  'Created by' are being removed from the ports makefiles.

  Created by lines have historically been used to attribute contributions
  to the original creators of the ports. However, those might no longer
  be contributing to the port

20220430:
AUTHOR: tcberner@FreeBSD.org

  A new USES has been added to handle dependency on gstreamer.

  Instead of writing

        USE_GSTREAMER1=[list of components]

  you now have to write

        USES=gstreamer
        USE_GSTREAMER=[list of components]

  If your port previously set just

        USE_GSTREAMER=yes

  this now is simply

        USES=gstreamer

20220415:
AUTHOR: amdmi3@FreeBSD.org

  A new USES has been added to handle testing with pytest.

    USES=           pytest

  Introduces dependency on pytest and adds do-test target which calls
  pytest with the right environment and arguments.

  Additionally, PYTEST_{IGNORED,BROKEN}_TESTS knobs are provided for
  skipping failing tests in a convenient and documented way.

20220218:
AUTHOR: jrm@FreeBSD.org

  A new USES has been added to change an ELF binary's feature control note.

    USES=           elfctl
    ELF_FEATURES=   +noaslr,wxneeded:foo \
                    -noprotmax:foo \
                    +nostackgap:bar

  Turns on noaslr and wxneeded and turns off noprotmax for the ELF
  binary foo and turns on nostackgap for the ELF binary bar.

  The file paths listed in ELF_FEATURES are relative to ${BUILD_WRKSRC}.
  File modifications are made post-build as certain test targets may run on
  the build-tree binaries.

AUTHOR: kde@FreeBSD.org

  PyQt modules have been merged into devel/py-qt5-pyqt.

  This allows us to simplify PyQt framework and to be in adequacy with the
  packages that the author of these libraries proposes, namely:

  * PyQt - devel/py-qt5-pyqt
  * PyQt-Charts - x11-toolkits/py-qt5-chart
  * PyQt-NetworkAuth – net/py-qt5-networkauth
  * PyQt-WebEngine – www/py-qt5-webengine
  * SIP – devel/py-sip
  * py-sip - devel/py-qt5-sip
  * PyQt-builder - devel/py-qtbuilder
  * Qscintilla - devel/py-qt5-qscintilla2

  Ports depending on PyQt, must be declared with USE_PYQT=pyqt5 instead of
  USE_PYQT=core gui svg etc.

AUTHOR: tobik@FreeBSD.org

  Standalone USE_GL, USE_GNOME, USE_MATE, USE_PHP, USE_SDL,
  USE_XORG have been deprecated for a while. For migration
  purposes the framework automatically loaded the corresponding
  USES={gl,gnome,mate,php,sdl,xorg} with a warning. The migration
  period is now over and you must add the USES manually for USE_*
  to have any effect.

20220111:
AUTHOR: se@FreeBSD.org

  The CPU_AND, CPU_ANDNOT, CPU_OR, and CPU_XOR macros in 14-CURRENT
  and 13-STABLE after this date have been made compatible with GLIBC
  conventions. Specifically, they now take 3 arguments instead of 2.
  Ports can check whether the CPU_ALLOC macro is defined and then
  use the 3 parameter form, e.g.:

    #ifdef CPU_ALLOC
	CPU_AND(dst, dst, src);
    #else
	CPU_AND(dst, src);
    #endif

20211211:
AUTHOR: tcberner@FreeBSD.org

  A new USES has been added to depend on ImageMagick.

     USES=magick

  adds a LIB_DEPENDS on graphics/ImageMagick${IMAGEMAGICK_DEFAULT}.

  If a specific version is required, use for example

     USES=magick:6        resp.     USES=magick:7

  If only a build, run or test is required, use for example

     USES=magick:build    resp.     USES=magick:6,build,test

  If a dependency on the nox11 flavor is required, use for example

     USES=magick:nox11    resp.     USES=magick:7,nox11,run,test

  See magick.mk for more details on the available flags.

  The default compression for INDEX file as fetch via make fetchindex has
  switched from .bz2 to .xz (.zst is also available).

  The .bz2 format is still available but is considered deprecated and may
  be removed in the future.

20211010:

  INSTALLS_ICONS has been replace by a trigger on gtk-update-icon-cache.
  the macro does nothing anymore.

  WANT_OPENLDAP_SASL is removed now that OpenLDAP is always built with
  SASL support.

20210730:
AUTHOR: tcberner@FreeBSD.org

  A new USES has been added to depend on the mlt multimedia framework.

  Ports that depend on mlt should now use USES=mlt:<version> to specify
  their dependency.

  At the moment the supported version is 6, but will be extended to also
  allow for selection of mlt 7 shortly.

  The prepare-commit-msg hook was enhanced to auto-fill the first line of the
  commit with the category/port in case only one port was committed to.

20210525:
AUTHOR: amdmi3@FreeBSD.org

  PYTHON_REL has been switched from a 4 digits number to a 5 digits number to
  handle python 3.10.0.  Ports checking for python 3.7.10 should compare
  PYTHON_REL against 30710 and ports checking for python 3.10.0 should compare
  PYTHON_REL against 31000.

20210420:

  New default version for librsvg2.

  Current versions of graphics/librsvg2 are using parts written in rust.
  For architectures that do not have support for rust, and for people
  who prefer not to have, or are not able to compile rust software due
  to hardware limitations, the version can be chosen via this new flag.

  The default on almost all architectures is rust.

  If you prefer no to use rust, add the following to your make.conf:

  	DEFAULT_VERSIONS+=librsvg2=legacy

  New virtual category: education.

  This category comprises ports that are mainly educational in nature or
  purpose, such as:
  * course-writing or course-delivery applications,
  * classroom or school management applications (eg, scheduling classes),
  * applications, utilities, or games primarily or substantially designed
    to help the user learn a specific topic or study in general, like typing
    tutors, flashcard applications, or educational games.

  Patents are a complicated topic, and their regulation varies depending on
  jurisdiction. Patents are not necessarily related to the license and so
  should not be connected to the license framework.

  Patent limitations within the ports tree have been removed and left to the
  user or consumer to deal with their local legislation to determine if they
  can use the software without legal restrictions.

  New @rmempty keyword
  Its purpose is to delete empty files at deinstallation time. It is meant
  to be used for generated files/untracked by the package manager files.

  packages scripts and keywords can both be written in lua (version 5.3), see
  pkg-lua-script(5) for the API.

  Note that all scripts written in lua will:

  - run inside a capsicum sandbox,
  - be rootdir compatible (see pkg -r option)
  - be cross installation compatible example: installing packages in an arm64
    rootdir on and amd64 host.

  pyqt.mk gained support for test-only dependencies. If a component, say
  py-qt5-gui is only required for testing, you can add

    USE_PYQT=<other_deps> gui_test

20200514:
AUTHOR: mat@FreeBSD.org

  Add PATCH_CONTINUE_ON_FAIL to allow patching to go through all the patches
  even if one fail.

  This helps when upgrading ports with a large number of patches, like
  www/chromium where having to fix one patch, re-do the patching, fix the
  fallout, 800 times, is really painful.

20200414:
AUTHOR: bapt@FreeBSD.org

  package scripts can now be done in lua, the following are supported:

  - pkg-pre-install.lua
  - pkg-post-install.lua
  - pkg-pre-deinstall.lua
  - pkg-post-deinstall.lua

  see pkg-lua-script(5) for more details.

  USES=lua gained flavors.

  Ports using USES=lua:module or lua:flavors will be flavored.  A range of
  supported lua versions can be set using XX-YY (or XX-, or -YY, or simply ZZ)
  for ports not supporting all lua versions.

  USES=lua sets LUA_FLAVOR that needs to be used on all dependencies of
  flavored lua ports, in a similar way as PHP or Python flavors.

  BINARY_WRAPPERS allow to push in front of the PATH wrappers for binaries.
  This is useful when 2 tools do provide the same feature, but the configure

  USES=xfce now defaults to gtk3, so for ported applications requiring
  GTK2 XFCE support USES=xfce:gtk2 should be used.

  The ports tree now supports overlays

  overlays are a way to help users to integrate their own ports tree
  with the official ports tree without having to maintain clone of the
  official tree and remerge on regular basis.

  The ports tree will lookup in the overlays (in the order the are listed in
  OVERLAY variable) for the dependencies and the USES. It will use the first
  found.

  in order to use it the user have to declare his overlays that way in their
  make.conf:
  OVERLAYS= overlay1 overlay2 overlay3

  depend on Qt slightly.

  Previously one would have written
  	USE_QT4=foo bar
  or
  	USE_QT5=foo bar
  while now one has to write
  	USES=qt:4
  	USE_QT=foo bar
  respectively
  	USES=qt:5
  	USE_QT=foo bar

  Further qmake.mk no longer respects QT_NONSTANDARD. Ports that don't want to
  get the configure environment provided by qmake.mk should add the argument
  no_env, ports that don't want the configure target should specify no_configure.

  Ports using USES=php:phpize, php:ext, php:zend, and php:pecl are now
  flavored.  They will automatically get flavors (php56, php70, php71, php72)
  depending of the versions they support (set with IGNORE_WITH_PHP).  As a
  consequence, ports using USES=pear and USES=horde are also flavored.

  As all packages must have different package names, the following variables
  must be used in PKGNAMEPREFIX/SUFFIX:

    Variable                     + Values                +
    --------------------------------------------------------------------------------------
    PHP_PKGNAMEPREFIX            | php56- php72-         | PHP Extensions
                                 |                       | and modules

                                 |                       | automatic

    PEAR_PKGNAMEPREFIX           | php56-pear-           | PEAR modules
                                 |                       | without PEAR_CHANNEL
    PEAR_<channel>_PKGNAMEPREFIX | php56-pear-channel-   | with PEAR_CHANNEL
                                 |                       | automatic

  In all the ports with PHP dependencies, the *_DEPENDS entries MUST end with
  the flavor so that the framework knows which to build/use.  This is done by
  appending '@${PHP_FLAVOR}' after the origin.  For example:

    RUN_DEPENDS=  ${PEAR_PKGNAMEPREFIX}Validate>=0.5.0:devel/pear-Validate@${PHP_FLAVOR} \
                  ${PECL_PKGNAMEPREFIX}smbclient>=0.8.0:net/pecl-smbclient@${PHP_FLAVOR} \

  PHP applications (for example, www/wordpress) can also get flavors, add the
  flavors keyword to USES=php, for example: USES=php:flavors, and add
  ${PHP_PKGNAMESUFFIX} to its PKGNAMESUFFIX.

                          ${PATCHDIR}/feat-foo-patch-file2.c

  USES=qmake now accepts a new variable, QMAKE_CONFIGURE_ARGS.

  Starting with Qt 5.8.0, qmake can use configure.json files to help define
  configuration options and configuration time checks. These options are
  generally in the form '-foo -no-bar', and must be passed after "--" at the
  end of qmake's command line.

  The QMAKE_CONFIGURE_ARGS variable allows one to set those options, and
  USES=qmake takes care of passing them at the right position when invoking
  qmake.

  There is a new USES=eigen to depend on math/eigen[23].

  Usage:
    USES=eigen:<version>[,<type>]

    version: 2 or 3 (required)
    type:    build (default), run

  For example:
    USES=eigen:2,build,run
  will add a BUILD- and RUN_DEPENDS on math/eigen2, and
    USES=eigen:3
  will add a BUILD_DEPENDS on math/eigen3.

  USES=cmake now supports two additional list variables:
    * CMAKE_ON  : List of variables to turn on
    * CMAKE_OFF : List of variables to turn off
  This can be used as a shortcut to append these to CMAKE_ARGS.

  For example ports that previously set
    CMAKE_ARGS=		-DVAR1:BOOL=TRUE -DVAR2:BOOL=TRUE -DVAR3:BOOL=FALSE
  can now set this as
    CMAKE_ON=		VAR1 VAR2
    CMAKE_OFF=		VAR3

  Ports using USE_PYTHON=distutils are now flavored.  They will automatically
  get flavors (py27, py34, py35, py36) depending on what versions they support.

  There is also a USE_PYTHON=flavors for ports that do not use distutils but
  need FLAVORS to be set.  A USE_PYTHON=noflavors can be set if the port is
  using distutils but flavors are not wanted.

  A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been added
  to cope with Python ports that did not have the Python PKGNAMEPREFIX but are
  flavored.

  USES=python now also exports a PY_FLAVOR variable that contains the current
  python flavor.  It can be used in dependency lines when the port itself is
  not python flavored, for example, deskutils/calibre.

  By default it will only generate flavors for the versions in PYTHON2_DEFAULT
  and PYTHON3_DEFAULT.  Define BUILD_ALL_PYTHON_FLAVORS in your make.conf to
  generate all possible flavors.  A port can set USE_PYTHON=allflavors to have
  all the flavors and not simply the default ones.

  In all the ports with Python dependencies, the *_DEPENDS entries MUST end
  with the flavor so that the framework knows which to build/use.  This is done
  by appending '@${PY_FLAVOR}' after the origin.  For example:

    RUN_DEPENDS=	${PYTHON_PKGNAMEPREFIX}six>0:devel/py-six@${PY_FLAVOR}

  To help with flavored ports, helpers are available.  In these, replace <*>
  with the flavor name.

  *_PKGNAMEPREFIX *_PKGNAMESUFFIX *_PLIST *_DESCR will overwrite the variable.

  *_CONFLICTS *_CONFLICTS_BUILD *_CONFLICTS_INSTALL *_PKG_DEPENDS
  *_EXTRACT_DEPENDS *_PATCH_DEPENDS *_FETCH_DEPENDS *_BUILD_DEPENDS
  *_LIB_DEPENDS *_RUN_DEPENDS *_TEST_DEPENDS will append to the variable.

  For example:

    flavor2_PKGNAMESUFFIX=	-foo

  can replace:

    .if ${FLAVOR:U} == flavor2
    PKGNAMESUFFIX=	-foo
    .endif

  Flavors are a way to have multiple variations of a port.  The port is built
  multiple times, with the variations.  To declare flavors, set the FLAVORS
  variable to the flavors you want defined.  The first flavor will be the
  default:

    FLAVORS=   flavor1 flavor2

  The flavors MUST be lowercase, and can contain [[:lower:][:digit:]_].

  Then, when building the port, pass the FLAVOR as an argument after make to
  select the flavor.

    $ make install FLAVOR=flavor2

  In the port, you can then change the behavior depending on the value of the
  FLAVOR variable.  Note that the different flavors MUST have different
  PKGNAMEs.  Be sure to guard against an empty FLAVOR variable by using
  ${FLAVOR:U}:

    .if ${FLAVOR:U} == flavor2
    PKGNAMESUFFIX=	-foo
    OPTIONS_DEFAULT+=   FOO
    .endif

  HTTPS certificates are now verified when "make makesum" fetches distfiles.
  If this fails make sure you have a CA certificate bundle installed such as
  security/ca_root_nss.  If it still fails and there are other HTTPS sites
  with a valid certificate consider removing the site from MASTER_SITES.
  If the site cannot be removed you can disable certificate verification by
  adding the following line to the port Makefile:

  * Qt 4's binaries have been moved to lib/qt4/bin to match what is already done
    to Qt 5's binaries. Since these binaries are no longer in ${LOCALBASE}/bin,
    they also do not have the -qt4 suffix in their names any more.

  * Consequently, there are no Qt 4 or Qt 5 binaries in the default $PATH, and
    misc/qtchooser is now used to select the actual Qt binaries. In other
    words, calling "qmake" or "moc" now goes through qtchooser, which prefers
    Qt 5 binaries by default.

    The ports framework handles this automatically. The UPDATING entry covers
    this in more detail.

  * Qt 5.7.1 requires a C++11-capable compiler to be used. qmake and CMake pass
    the appropriate flags to the compiler (such as -std=c++11) automatically,
    but if your port fetches Qt's build flags via pkg-config (which can be the
    case for autotools-based ports), you might need to take care of this
    manually by setting USE_CXXSTD in your Makefile:

      USE_CXXSTD=	c++11

  A new EXTRA_PATCH_TREE has been added.  Points to a directory hierarchy with
  the same layout as the ports tree, where local patches can be found.  This
  allows a third party to keep their patches in some other source control
  system if needed.

  For example, if you have EXTRA_PATCH_TREE=/patches, when building
  lang/perl5.24, any file named patch-* in /patches/lang/perl5.24/ will be used
  to patch the Perl distribution.

  To complete the USE_GITHUB framework, a GH_SUBDIR variable has been added.
  It automatically moves a secondary distfile to the right place inside WRKSRC.
  It also extends the GH_TUPLE variable to make it as easy to use as possible.

  This adds the possibility to use regular expressions for the makeplist stage
  of the PLIST_SUB life.

  From time to time, the values are too generic, and they get in the way of
  other stuff.

  This adds the possibility to have a VAR_regex=regex that will be used
  instead of the VAR=string to search for possible replacements.

  For example, in lang/perl5*, there is PERL_ARCH=mach, which will get replaced
  in paths if a file is called, say "machine", will end up being
  "%%PERL_ARCH%%ine".  Adding PERL_ARCH_regex="\bmach\b" will ensure only full
  words are replaced, so machine will stay machine, but "lib/mach/foo "will
  still be replaced by "lib/%%PERL_ARCH%%/foo".

  Change the meaning of NO_WRKSUBDIR to force a WRKDIR != WRKSRC.

  Right now, NO_WRKSUBDIR means that the extraction does not produce a
  subdirectory, and that everything goes straight into WRKDIR.  It is
  problematic, because during the build of a port, quite a few files
  are created in there, and then, a stage directory, where everything
  is installed, and then a pkg directory where the package is created,
  and those often conflict, or get in the way, of the building
  process.

  With this, NO_WRKSUBDIR will extract the distfiles directly into
  WRKSRC instead of WRKDIR.  In this case, WRKSRC is artificial and is
  based on PKGNAME and not DISTNAME, mitigate conflicts with rc files.

  Implemented complete support for test target.

  You can now `make test' on any port to run test sequence, no-op by default.
  If a port defines TEST_TARGET, it'll run sub-make with specified target,
  usually `check' or `test', useful if upstream supports that. The port may
  instead define custom do-test target, as well as usual satellite targets:

    {pre,do,post}-test, {pre,do,post}-test-OPT, {pre,do,post}-test-OPT-off

  `make test' builds and stages port first, so test may use both WRKDIR and
  STAGEDIR, and both BUILD and RUN depends are available for test target.
  Additionally, TEST_DEPENDS is now properly supported and may be used to
  define additional depends specifically for testing.

  Framework may define default tests for specific cases. For instance,
  perl5.mk and cran.mk provide default test target on their own.

  Extend the multiple distfiles USE_GITHUB framework by allowing it to fetch
  only additional distfiles, but not the main one.  Set USE_GITHUB=nodefault
  and use the GH_* variables with groups as usual.

20150528:
AUTHOR: mat@FreeBSD.org

  USE_GITHUB can now fetch multiple distfiles.  It uses a grouping feature
  similar to MASTER_SITES/PATCH_SITES.

  Some helpful variables are provided: WRKSRC_<group> for putting things in the
  right place in post-extract, and DISTNAME_<group>/DISTFILE_<group> for use
  with EXTRACT_ONLY.

  A simple example:

    PORTNAME=     bar
    PORTVERSION=  1.0
    USE_GITHUB= yes
    GH_ACCOUNT= foo
    GH_PROJECT= ${PORTNAME}-images:images

    post-extract:
	    @${MV} ${WRKSRC_images} ${WRKSRC}/images

  It will fetch those two distfiles:

    $ make fetch-urlall-list
    https://codeload.github.com/foo/bar/tar.gz/1.0?dummy=/foo-bar-1.0_GH0.tar.gz
    https://codeload.github.com/foo/bar-images/tar.gz/1.0?dummy=/foo-bar-images-1.0-1.0.tar.gz

  It will then extract them to ${WRKDIR} in their respectives directories.

  The way Perl modules are installed has changed.  Before, we had

    site_perl/perl_arch : lib/perl5/site_perl/5.18/mach
    perl_man3 :           lib/perl5/5.18/man/man3

  Now we have :

    site_perl : lib/perl5/site_perl
    site_arch : lib/perl5/site_perl/mach/5.18
    perl_man3 : lib/perl5/site_perl/man/man3

  Modules without any .so will be installed at the same place regardless of the
  Perl version, minimizing the upgrade when the major Perl version is changed.
  It uses a version dependent directory for modules with compiled bits.

  As PERL_ARCH is no longer needed in plists, it has been removed from
  PLIST_SUB.

  The USE_PERL5=fixpacklist keyword is removed, the .packlist file is now
  always removed, as is perllocal.pod.

  Building ports in a chroot or jail have always required a particular
  environment be setup. This was not clear though and the ports framework
  did not enforce it. These requirements are:
    1. Either a SRC_BASE/sys/sys/param.h, or /usr/include/sys/param.h be
       present with the __FreeBSD_version_ number of the target system,
       or OSVERSION be set in the environment. Lack of these would fallback
       on kern.osreldate before, which is no longer the case.
    2. UNAME_r,UNAME_v,UNAME_s all must be set for the target system.

  Not having these values in sync will now cause the build to error until it is
  resolved.

  Setting these in the environment can be done via your own wrapper scripts,
  or /etc/login.conf (along with cap_mkdb /etc/login.conf) or
  via /etc/make.conf using appropriate values. Note that OSVERSION is redundant
  if a proper param.h is in the environment:

    OSVERSION+=     1100036
    UNAME_ENV+=     OSVERSION=${OSVERSION}
    UNAME_ENV+=     UNAME_s=FreeBSD
    UNAME_ENV+=     UNAME_r=11.0-CURRENT
    UNAME_ENV+=     UNAME_v="${UNAME_s} ${UNAME_r}"

  New PYTHON_CONCURRENT_INSTALL knob to support the parallel installation
  of ports for different python versions.

  If set to yes, the knob indicates that the port can be installed for
  different python versions at the same time. The port will use a unique
  prefix for certain directories using USES=uniquefiles:dirs (see the

  receive an additional suffix, based on ${PYTHON_VER}.

  The values for the uniquefiles USES are set as follows:

  If the port is installed for the current default python version, scripts and

  New USES=uniquefiles to make files or directories unique
  by adding a prefix or suffix to them.

  Files listed in UNIQUE_PREFIX_FILES will receive the prefix
  set via UNIQUE_PREFIX. The same applies to UNIQUE_SUFFIX_FILES,
  but with the chosen UNIQUE_SUFFIX. UNIQUE_PREFIX and
  UNIQUE_SUFFIX are set to PKGNAMEPREFIX and PKGNAMESUFFIX by
  default.
  The uniquefiles USES enables ports to name files in special
  ways, e.g. by outlining that the port does not support X11
  (-nox11). A binary named bin/foo thus can be easily renamed
  to bin/foo-featureA via

  USES=			uniquefiles
  UNIQUE_SUFFIX=	-featureA
  UNIQUE_SUFFIX_FILES=	bin/foo

  The uniquefiles USES automatically adjusts the plist at
  installation time. There is no need to consider the prefix
  or suffix in the pkg-plist file itself. If the original name
  of the renamed file is bin/foo, this exact name should be put
  into pkg-plist.

  The dirs argument to USES=uniquefiles will cause certain
  standard directories, such as DOCSDIR or EXAMPLESDIR to be
  prepended with the UNIQUE_PREFIX. The change to the directories
  will hapen prior to configuring or building the port, so that
  the port Makefile as well as the port's build logic are aware
  of the changed name.

  Since the uniquefiles USES effectively manipulates the port's
  installation and file layout, it will only be available for
  stagedir-aware ports. Ports with NO_STAGE=yes will be unable
  to use the uniquefiles USES.

  lang/python (and as such the 'python' binary and accomplices)
  has been removed as default dependency for the USE_PYTHON,
  USE_PYTHON_BUILD and USE_PYTHON_RUN knobs.

  Ports need to use a designated (default) python interpreter
  to build and install and in most cases for execution in the user
  environment. Ports that install python scripts, which are not
  limited to a certain python version (or version range), can
  include lang/python as build and/or run dependency.

  USE_PYTHON=yes and similar knobs will only pull in the
  default python version (e.g. lang/python27), but none
  of the meta ports or lang/python itself.

  Please use lang/python as build or run-time dependency only,
  if there is no other way to get a port working properly, since
  the usage of lang/python complicates package builds for different
  python versions.

  share/applications directory was added to the mtree, meaning that
  you no longer need to create or remove it in your ports.

  New "compiler" USES to be able to select the compiler based on the
  features it provides.
  Supported arguments are:
  - c++11-lang: the port needs a c++11 aware compiler what ever standard
  library it uses, implies features
  - c++11-lib: the port needs a c++11 standard library, implies features
  - c11: the ports needs a c11 aware compiler implies features
  - features: this will create a COMPILER_FEATURES variable which contains
  the list of features ${CC} do support, implies env.
  - env: the COMPILER_TYPE will be set to either gcc or clang.

  By default the uses will try to use clang33 from ports when nothing in
  base is relevant except if the user explicitly defines
  FAVORITE_COMPILER=gcc in his make.conf

  New USES: qmake, configure tool widely used among Qt based projects.
  New framework is stage-friendly. To convert existing ports remove
  custom configure target, adjust QMAKE_ENV, QMAKE_ARGS, QMAKE_PRO if
  required (see Mk/Uses/qmake.mk for details).

  PATCHFILES now support an optional :-pX flag that notes which patch strip
  level to use. This allows multiple patches in 1 port to use different
  PATCH_DIST_STRIP values without changing PATCH_DIST_STRIP.

  Syntax: PATCHFILES= patch[:-pX][:distgroup]

  Stage aware ports can now create package without the requirement from
  being root.
  If a port really needs root anyway it should add NEED_ROOT in its
  Makefile.

  For a port that needs special credential on files DO NOT RELY on
  chown in post-install section but rely on @own, @group in pkg-plist
  Be careful about rights on directories as pkg_install cannot store them
  they needs to be done via @exec chown.

20130923:
AUTHOR: bapt@FreeBSD.org

  The ports tree is now staged by default. With pkgng the sequence hasn't
  changed, the main difference is that creating package is now independent
  from installing it. With pkg_install, the package is now created first
  and make install, do install the package.

  New macros:
  - STAGEDIR: PATH to the directory where the port will be staged.
  - NO_STAGE: Keep the old behaviour of the ports tree (aka no staging area)

  Unsupported macro if NO_STAGE is not set:
  - MAN* with staging man page compression and handling of hardlinks and
  symlinks is automatically done in the stage. the manpages becomes then a
  "normal" plist files and should be tracked in pkg-plist.
  - MANCOMPRESSED the compress-man target is able to only compress when it
  needed.

  New target:
  - stage: this installs everything into the stage directory
  - makeplist: this will create a pkg-plist and print it to stdout. This is
  a sample plist and it should always be _reviewed_ not directly used.

  NOTE: with staging only what is in the plist will be installed, nothing more,
  meaning a port staged cannot have leftovers except directories left. It is
  really important to double check the pkg-plist to make sure all the files
  the maintainer wants to package are in! make makeplist can help in that area.

AUTHOR: bdrewery@FreeBSD.org

  SSP support has been added to ports with WITH_SSP_PORTS for i386 and amd64
  on FreeBSD 10, and amd64 on earlier versions.

  SSP_UNSAFE is added to disable in a port if it fails to build, but
  this should only be used in rare circumstances such as kernel modules.
  Otherwise, the port may just be failing due to lack of respecting
  LDFLAGS.

  On FreeBSD 10, this uses an ldscript in /usr/lib/libc.so to pull in
  libssp_nonshared.a to address issues linking on i386 [1].

  On earlier FreeBSD versions the WITH_SSP_PORTS knob will add -lssp_nonshared
  to LDFLAGS on i386. This is not needed on amd64. However, several hundred
  ports do not currently respect LDFLAGS, so this support is disabled currently
  as it causes build failures if a dependency is looking for the stack_chk
  symbols.

  * Two new USES macros to handle mime data of ports.

  USES= desktop-file-utils
	Handles MimeType in .desktop files that are installed in
	share/applications.
  USES= shared-mime-info
	For supporting mime xml files installed in
	share/mime/packages.

  The desktop-file-utils USES is only needed if the .desktop files
  installed by the port has a MimeType field.
  USE_GNOME=desktopfileutils is deprecated.

  The shared-mime-info USES handles mime types xml files.
  Please note that only the packages/${NAME}.xml file should be listed in
  the plist. The shared-mime-info port will clean up the share/mime/*
  directories and generated files.

  Both USES have there own post-install and code that adds @exec/@unexec
  lines to the pkg-plist. This means that when a port switches to the
  USES macro, the related post-install command  and @exec/@unexec
  lines can be removed from the prot.

  ncurses
  USES= ncurses:base will force to link against base version of ncurses.

  USES= readline will make the port link against base version of readline except
  on 10+ where it will force dependency on the port version of readline
  USES= readline:port will anyway force dependency on the port version of
  readline.

    devel/ccache). Therefore new user settable variables are available:

    WITH_CCACHE_BUILD - Enable CCACHE support (Default off)

    NO_CCACHE         - Disable CCACHE support for example for certain
                        ports if CCACHE is enabled.

    By default CCACHE uses $HOME/.ccache as cache directory. To use
    a non-default cache directory this could be overwritten like:

    MAKE_ENV+= CCACHE_DIR=/var/cache/ccache

  * GitHub support has been integrated into bsd.sites.mk. In order to
    fetch distfiles from GitHub, a port must define USE_GITHUB along
    with the following variables:

    GH_ACCOUNT  - account name of the GitHub user hosting the project
                  default: not set, mandatory

    GH_PROJECT  - name of the project on GitHub
                  default: ${PORTNAME}

    GH_TAGNAME  - name of the tag to download (master, 2.0.1, ...)
                  default: ${DISTVERSION}

    GH_COMMIT   - first 7 digits of the commit that generated GH_TAGNAME
                  (man git-describe(1))
                  default: not set, mandatory

  * USE_GHOSTSCRIPT now supports a version number which the port
    requires.  The valid value is "7" or "8".  If other value is
    specified, value of WITH_GHOSTSCRIPT_VER is used.

  * WITH_GHOSTSCRIPT_GNU has been removed in favor of
    WITH_GHOSTSCRIPT_VER.  The valid value of WITH_GHOSTSCRIPT_VER is
    "7" or "8", and the default value is "8".

   * CONFIGURE_ARGS is updated to use correct syntax for newer autoconf
     on the configure target. Individual ports no longer need to change
     CONFIGURE_TARGET to have the '--build=' prefix.

  * By default, ports-mgmt/pkg_install now sets up a wrapper to use ports
    pkg_install (when installed) instead of base when the former is more
    recent. This can be disabled in the options menu, or with the
    WITHOUT_WRAPPER knob.

  * @rmtry is now supported in pkg-plist.

  * USE_DISPLAY made more powerful, see comments in bsd.port.mk for details.

  * ${PW} is now defined.

  * LIB_DEPENDS can now be used with libraries with + sign in their name
    without the need for escaping.

  * The Perl-related code parts have been extracted from bsd.port.mk to
    bsd.perl.mk.  This includes the user-settable knobs (e.g. USE_PERL5)
    and infrastructure parts of the code, like default targets.  The new
    code is designed to be conditionally included based on either
    USE_PERL5_*, PERL_CONFIGURE, or PERL_MODBUILD being set.  However,
    some of the default settings remain in bsd.port.mk while we make
    sure that all ports comply with this.

  * A convenient version handling has been implemented for Perl-related
    knobs.  With this new feature one can require a minimal, a maximal or an
    exact version, that the given port needs.  For the full description and
    some examples, please see the documentation in bsd.perl.mk.

AUTHOR: gabor@FreeBSD.org
The following functional changes were made to bsd.*.mk and to
Tools/scripts/security-check.awk:

  * The variable definitions that cover command line tools, e.g. MKDIR, were
    extracted from bsd.port.mk into bsd.commands.mk, so that we can
    reuse them within the infrastructure later.

  * The old DESTDIR implementation was removed both from the infrastructure,
    and from the individual ports.  Variables like TARGETDIR should not longer
    be used.

  * A new DESTDIR implementation has been added, implemented in bsd.destdir.mk.
    The new implementation puts no requirements on the individual ports.

AUTHOR: python@FreeBSD.org

  * The default Python version has been changed from 2.4.x to 2.5.x.

  * A number of variables have been added to bsd.python.mk to support
    the more integrated support for Python eggs, including:
    PYDISTUTILS_PKGNAME, PYDISTUTILS_PKGVERSION, PYEASYINSTALL_EGG,
    PYDISTUTILS_NOEGGINFO, PYDISTUTILS_EGGINFO, PYEASYINSTALL_ARCHDEP

  * More detailed descriptions of the variables can be found in the comments
    in bsd.python.mk.

  * Add knob USE_FORTRAN for ports which uses FORTRAN. All ports uses
    FORTRAN compiler should use this knob. Usages are: USE_FORTRAN=yes
    (default;gfortran42), USE_FORTRAN=ifc (Intel FORTRAN compiler)
    and USE_FORTRAN=g77 (/usr/bin/f77 or g77-34).

The following change was made to the ports infrastructure:

  * Virtual category 'kld' was added.  If the port installs kernel loadable
    modules, it should be included in this category.

The following changes were made to the ports infrastructure:

  * The 'make-deinstall-all' target now checks for moved ports.

  * The installation directories PORTEXAMPLES and PORTDATA are now defined.

  * The USE_MAKESELF knob is added for ports that use the makeself archiver.

  * The description of fetch-list was updated.  The targets fetch-required-list,
    fetch-url-list, and fetch-urlall-list were added.

  * 'make search' will also now search in ports/MOVED.

  * The default method for 'make update' is now portsnap.  Previously,
    you had to manually select one of 3 methods: SUP_UPDATE, CVS_UPDATE,
    or PORTSNAP_UPDATE.  The latter is now obsolete.

  * Several Makevar definitions have been moved to the pre-makefile section:
    DATADIR, DOCSDIR, ETCDIR, EXAMPLESDIR, WWWDIR.

20070403:
AUTHOR: portmgr@FreeBSD.org
The following changes were made to the ports infrastructure:

  * The default dependency of USE_GHOSTSCRIPT has been changed from
    ghostscript-gnu to ghostscript-gpl.  The WITH_GHOSTSCRIPT_GPL variable is
    now no-op.  New WITH_GHOSTSCRIPT_GNU variable was added.

  * bsd.tcl.mk was overhauled.  Most importantly, the semantics of USE_TCL* and
    USE_TK* variables was changed.  USE_TCL and USE_TK now implies both build
    and run dependencies, USE_TCL_RUN and USE_TK_BUILD variables were
    introduced. Existing ports in the tree were modified.

  * Unused category 'tcl81' was removed, and new categories 'tcl' and 'tk'
    were added.

The following changes were made to the ports infrastructure:

  * Default LIBTOOLFILES value was changed from literal `configure'
    to ${CONFIGURE_SCRIPT}.

  * bsd.efl.mk was moved to ports/Mk.  USE_EFL family of macros is now
    generally available to all ports.

  * New macros COPYTREE_BIN and COPYTREE_SHARE were added, to allow
    for easy installation of a tree hierarchy, either with executable (bin)
    or read-only (share) permissions on files.

  * A new variable WWWDIR was added, with default value of
    ${PREFIX}/www/${PORTNAME}.

  * Variables DOCSDIR_REL, DATADIR_REL, EXAMPLESDIR_REL and WWWDIR_REL were
    added for porter's convenience.  They contain the values of their
    respective non-REL variables, except relative to installation PREFIX.

  * The FETCH_CMD was refactored so that ports can override the command,
    the arguments, or both.

The following changes were made to the ports infrastructure:

  * The remaining vestiges of FreeBSD 4.X support were removed.  Any
    remaining users of 4.X should have stayed with the RELEASE_4_EOL tag.

  * It is now possible to include USE_PHP after bsd.port.pre.mk.

  * 'make search' should now work with non-default ${PORTSDIR}.

AUTHOR: portmgr@FreeBSD.org
The following changes were made to the ports infrastructure:

  * DEPENDS variable was removed, please use other *_DEPENDS variables instead.

  * A new pkg-plist keyword is available, @stopdaemon.  It will call forcestop
    on all rc.subr scripts installed by the port on deinstall, effectively
    stopping services on deinstall/upgrade.

  * rc.subr script suffix is now available in Makefile as RC_SUBR_SUFFIX.

  * New variable USE_CDRTOOLS was introduced.  It replaced direct dependencies
    on sysutils/cdrtools port.  It now automatically support switching to
    cdrtools-cjk port when user specified WITH_CJK.  All ports were converted.

  * USE_DOS2UNIX, infrastructure for converting DOS to UNIX line feeds, was
    enhanced by a new variable DOS2UNIX_REGEX.  It allows to specify a find
    -iregex parameter to limit touched files by file extensions.

  * Support for partially translated manpages was added.  For examples of
    usage, please refer to Porter's Handbook.

  * USE_TCL/USE_TK variables were changed to provide runtime dependency.  New
    variables USE_TCL_BUILD and USE_TK_BUILD were added.  All unintuitive
    quirks of these variables were fixed.

  * USE_LDCONFIG was fixed to work properly for ports, that specify @cwd in the
    pkg-plists.

  * Old bsd.java.mk version 1.0 macros were removed.

  * New category: ports-mgmt

  * New virtual category: gnustep

  * Unused 'picobsd' category was removed.

* GNOME is now installed into LOCALBASE.  Any port which makes use of the
  gnomeprefix component will have its PREFIX forced to LOCALBASE

20060930:
AUTHOR: portmgr@FreeBSD.org
The following functional changes were made to bsd.port.mk:

  * The bsd.port.mk pre and post includes have been split into 3 pieces
    instead of 2, to allow OPTIONS to be able to influence dependencies.
    This is still experimental and not yet enabled by any port.  This adds
    the file 'bsd.port.options.mk'.

  * bsd.gcc.mk has been updated to understand gfortran.

  * emulators/linux_base is now removed.  linux_base-fc4 has been the default
    for some time.

  * The USE_FIREBIRD macro was added to bsd.database.mk.

20060914:
AUTHOR: portmgr@FreeBSD.org
 The following functional changes were made to bsd.port.mk:

  * PKGVERSION was introduced as an intermediate variable refactored out of
    PKGNAME.

  * bsd.lua.mk was added to support lua-related ports.

  * DESTDIR was removed from bsd.scons.mk because it was problematic.

  * Some quotes were added to the 'missing' target to improve handling of
    duplicate origins.

AUTHOR:	sat@FreeBSD.org
The following functional changes were made to bsd.sites.mk:

  * MASTER_SITES variable can now look like MACRO1/subdir1 MACRO2/subdir2, and
    be expanded in a way that you expect it to, that is apply different subdirs
    to different sites. You can safely replace ${M_S_FOO:S/%SUBDIR%/bar/} with
    FOO/bar.

  * If M_S_SUBDIR is unset, a macro in M_S won't set it anymore, but rather
    substitute %SUBDIR% all by itself. Now it's possible to use macros with
    different default subdirs and they will expand in a proper way.

20060805:
AUTHOR:	sat@FreeBSD.org
The following functional changes were made to bsd.sites.mk:

  * MASTER_SITES variable can now contain special macros which are expanded into
    traditional URL[:group] syntax and cause some convenient effects, e.g. set a
    default M_S_SUBDIR.

  * A macro is any space-delimited word in MASTER_SITES without a forward slash.

  * If MASTER_SITE_<macro> is defined, then the macro is expanded to its value.

  * Abbreviated macros are provided for extremely popular locations, e.g. CPAN
    and SF. To avoid further obfuscation their unabbreviated equivalents should
    be avoided.

  * Popular macros can trigger M_S_SUBDIR to default to a predefined value, e.g.
    ${PORTNAME:L} for SF and ${PORTNAME:C/-.*//} for CPAN.

  * Abbreviations and M_S_SUBDIR defaults are defined by MASTER_SITES_ABBREVS
    and MASTER_SITES_SUBDIRS, both set in bsd.sites.mk.

  * If a macro belongs to a group (e.g. SF:source1), all the sites it expands
    into also belong to the same group.

  * Macros and traditional URL's can be mixed safely, their order stays intact.

20060804:
AUTHOR:	gabor@FreeBSD.org
The following functional changes were made to bsd.*.mk and to
Tools/scripts/security-check.awk:

  * Add DESTDIR support to let one install ports into a jail from outside.
    A package is installed under ${DESTDIR}${PREFIX} now and registered under
    ${DESTDIR}/var/db/pkg.

  * TARGETDIR variable has been added for referencing ${DESTDIR}${PREFIX}.

  * LOCALBASE, LINUXBASE and X11BASE variables point to the final destination
    now, LOCALBASE_REL, LINUXBASE_REL and X11BASE_REL can be used for the
    old behavior.  The behavior has not been changed in PLIST_SUB.
    Note, that the three variables are still overridable with a hack, so this
    change doesn't affect POLA, but necessary for DESTDIR support.

  * OSVERSION is now determined from the userland, not from the kernel.
    Cross-compiling between releases is still not supported, but this
    behavior is more correct for jails with differing userland from
    the kernel version.

  * Add some sanity check for PREFIX and DESTDIR.  This can be skipped by
    defining IGNORE_PATH_CHECKS, but very discouraged.

  * Deinstalling from DESTDIR, determining if a port is already installed in
    DESTDIR, etc. are implemented by chrooting those specific commands.

  * Text changes to reflect that we are installing to DESTDIR, removing from
    DESTDIR, etc.

Note, that this change implements only the infrastructure support.  Ports should
also be implemented to respect DESTDIR.

The following functional changes were made to bsd.port.mk:

  * Introduces IA32_BINARY_PORT for certain cases where a given port fetches
    and installs compiled i386 binaries.

  * Adds some infrastructure for support of 32-bit i386 apps on amd64.

  * Again fix USE_LDCONFIG logic to make it work with non-default PREFIX to
    fix bug introduced in previous revision.

The following functional changes were made to bsd.port.mk:

  * Change all bogus uses of BROKEN to IGNORE.  (Note: the BROKEN_WITH_*
    forms are retained for compatibility but deprecated.)  Internally,
    these variables all had already set IGNORE, not BROKEN, so they
    were really misnomers.

  * Fix USE_LDCONFIG with non-default PREFIX.

  * Fix DESKTOP_ENTRIES processing on 4.x.

  * Add 'make missing' to show missing dependencies.

  * Add bsd.scons.mk and bsd.wx.mk.

  * Switch default Linux X implementation from XFree86 to X.org to track the
    above [5]

  * Deprecate INSTALLS_SHLIB and replace it by USE_LDCONFIG.  If set to "yes",
    the old behavior is preserved.  Otherwise, it can be set to a list of
    directories to be added to ${PREFIX}/libdata/ldconfig/${UNIQUENAME}.
    Note that this directory is used by ldconfig startup script, it is meant
    to replace ldconfig scripts installed by some ports as (sometimes
    000.${UNQUENAME}.sh) [6]

  * Adds USE_LDCONFIG32 which is like USE_LDCONFIG but the target file is
    ${PREFIX}/libdata/ldconfig32/${UNIQUENAME} instead.  (Note: this should
    only be used on 64-bit architectures) [6]

  GNOME has been upgraded from 2.10.2 to 2.12.1.  This update brings with
  it many important porting changes:

  - gtk20's pkg-config file no longer contains the X11 pango modules.
    Therefore, if your port requires these modules, you may have to
    manually patch them in to your port's Makefiles.  Contact
    gnome@FreeBSD.org if you have questions on this.

  - A new USE_GNOME component, ltverhack, has been added.  This
    pseudo-component hacks libtool so that shared library versions are
    more consistent with other operating systems.  Using this component
    can prevent unnecessary shared library version changes.

  - A new macro, INSTALLS_ICONS, has been added.  If your port installs
    Freedesktop-style icons to ${LOCALBASE}/share/icons or
    ${X11BASE}/share/icons, then you should use this macro.  NOTE:
    use of this macro requires your port to set either USE_GNOME or
    WANT_GNOME.

  - USE_LINUX now implies NO_FILTER_SHLIBS=yes. It also doesn't use FreeBSD
    tools to strip binaries anymore, so it's not necessary anymore to override
    STRIP and STRIP_CMD.
  - USE_LINUX_PREFIX implies NO_MTREE now.
  - In the USE_LINUX case, USE_XLIB now depends upon the Linux X11 libraries
    instead upon the native FreeBSD libraries.
  - The variable LINUX_BASE_PORT contains a string which is suitable as an
    item in *_DEPENDS, so if a port BATCH_DEPENDS or FETCH_DEPENDS upon the
    default (or overridden) Linux base, ${LINUX_BASE_PORT} should be used
    instead of a hardcoded reference.
  - If USE_LINUX or OVERRIDE_LINUX_BASE doesn't point to an existing linux_base
    port and if USE_LINUX isn't set to "yes" (case insensitive), the port will
    be marked as IGNORE.

  The CVSup port has been upgraded with a patch to correct the
  handling of the "refuse" file for files that are in the CVS Attic.
  This solves a problem some people were having, where CVSup would
  delete their ports/INDEX* files even though the files were listed
  in the "refuse" file.  The bug fix is in the cvsupd server, so
  mirror sites  must upgrade their servers in order for this fix to
  help.  Meanwhile, adding "ports/Attic/INDEX*" to the refuse file
  serves as a work-around.

  Py-gnome2 lost many of its GNOME dependencies to a new port,
  py-gnome-extras.  Therefore, ports that used to depend on

  * Honor OPTIONS if PACKAGE_BUILDING or BATCH are defined.

  * Move all USE_GCC entries to new file - bsd.gcc.mk.  'test-gcc'
    target allows users to check gcc version if USE_GCC is used.
    Give maintainers opportunity to add '+' character to USE_GCC version
    for using specified and higher versions.

    Example:

    USE_GCC=3.3+

    builds ports with gcc version 3.3 and higher (3.4, 4.0).

  * Install startup scripts with the help of USE_RC_SUBR variable.

  * Add three new targets: config-recursive, rmconfig-recursive and
    config-conditional.  You can set or delete OPTIONS for all
    dependencies before every build.  config-conditional target is
    used to skip configuring ports which have already been
    configured.

  * Fix using of WANT_PGSQL_VER variable if PostgreSQL is already
    installed.

  The following changes were committed:

  * Define new macros: DATE, FMT, MKTEMP, OBJDUMP, and use
    command macro SORT.

  * Change layout of comments to 4 column tabs, remove lots
    of spaces and eight-column-tabs.

  * Introduce 2 new variables: SUB_FILES and SUB_LIST:

    Example:

    SUB_FILES=	pkg-message pkg-install
    SUB_LIST+=	"VERSION=${VERSION}"

    This looks for ${FILESDIR}/pkg-message.in and ${FILESDIR}/pkg-install.in
    Substitutions in SUB_LIST are applied to these files and the
    output is redirected to ${WRKDIR}.

    PKGMESSAGE will be set to ${WRKDIR}/pkg-message.
    PKGINSTALL will be set to ${WRKDIR}/pkg-install.

  * Document DEPRECATED and EXPIRATION_DATE variables.

  * Sanitize the intermittent output by the build infrastructure
    so that cutting and pasting from it no longer interferes
    with GNATS-tags.

  * Honor configure arguments for USE_XLIB if USE/WITH_LIBTOOL_ is
    used.

  * Properly document 'describe' target.

  * Properly remove directories at deinstallation time if ports sets
    a non-standard PREFIX.

  * Defaults INDEXFILE to INDEX-6 on 6-CURRENT.

AUTHOR: portmgr@FreeBSD.org
  The following changes were committed:

  * Fix INDEX build if MAINTAINER is not defined.

  * Remove USE_QT2 option, since qt2 is obsolete.

  * Better define and explain ARCH option.

  * Add new script Tools/make_readmes, to speedup 'readmes'
    target. Avoid recursing into individual port directories and run
    it at top level, after the category README.html files have been
    created.

  * Fix 'search' target and enable a case-insensitive search on 5-x.

  * Extend 'search' target and enable search by categories.

  * Remove 'tk42' and 'tcl76' categories since they're obsolete.

  * Introduce DISTVERSION variable, that can be set instead of
    PORTVERSION and is automatically converted in a conforming PORTVERSION.

    Example:

    DISTVERSION=	10Alpha3

    extends 10Alpha3 to 10.a3

    DISTVERSION=	3Beta7-pre2

    extends 3Beta7-pre2 to 3.b7.p2

  * Use --suffix option instead of -b for patch(1), to make it
    compatible with BSD patch(1).

  * Fix {WANT,WITH}_MYSQL_VER behavior, to deal with conflicting
    versions.

  As part of the ongoing autotools cleanup, devel/autoconf has been
  replaced with devel/autoconf253, and devel/automake with devel/automake15.

  The XFREE86_VERSION variable is replaced by the X_WINDOW_SYSTEM variable.
  XFREE86_VERSION may no longer be used by ports Makefiles.  X_WINDOW_SYSTEM may
  currently be set to xorg, xfree86-4, and xfree86-3 (please use :L in checking
  it).  Several X_*_PORT variables are provided by bsd.port.mk which map to the
  appropriate port for the X_WINDOW_SYSTEM chosen.

  There has been a big update to PHP ports and bsd.php.mk to add more
  flexibility and new features.
  Now a port may depend on a specific set of PHP extensions.  To do so,
  simply replace:

  USE_PHP=	yes

  with:

  USE_PHP=	ext1 ext2 ext3 ...

  in the port Makefile. A list of all PHP extensions is included in bsd.php.mk.
  If the requirement is a build dependency too, the port should also define:

  USE_PHP_BUILD=yes

  Moreover, the new knob WANT_PHP_SCR has been added to indicate that the port
  requires the 'php' binary to run.
  Last but not least, many common operations to build/install/register a
  PHP extension can now be omitted from the port Makefile if it defines:

  USE_PHPEXT=	yes

  For more information on this point and on additional variables, see
  bsd.php.mk.

  OpenLDAP version 2.2 is now the default.
  When your port links against the openldap client libraries use
    USE_OPENLDAP=	yes
  and do not depend on a particular version. A user (or package
  building cluster) can select the desired flavor with
  WANT_OPENLDAP_VER and WANT_OPENLDAP_SASL, but these must not
  be used in ports Makefiles.

  USE_LIBTOOL_VER now configures a port to use the ports version of libtool
  instead of its included version.  This was put in place to reduce the
  number of ad hoc patches to individual ports' libtools to prevent .la
  file installation as well as fix various threading problems.

  To restore the previous libtool behavior, use the new macro,
  USE_INC_LIBTOOL_VER.  It works the exact same way as USE_LIBTOOL_VER
  in that it takes a libtool version as its argument.

  For example, to use the included version of libtool with extra hacks
  provided by libtool-1.5, add the following to your Makefile:

  USE_INC_LIBTOOL_VER=	15

  To use the ports version of libtool-1.5, add the following to
  your Makefile:

  USE_LIBTOOL_VER=	15

  Note: these macros are mutually exclusive.  Your port should only include
  one or the other if it needs to make use of libtool.

  The following behavioral or feature changes were committed:

  * Support verbose index builds with INDEX_VERBOSE

  * Support glob expressions in USE_GETTEXT to allow more flexibility
    in the face of future gratuitous library version bumps by the gettext
    developers:

    USE_GETTEXT=yEs   # Works as before (case-insensitive)
    USE_GETTEXT=[5-7] # Accepts any of those libintl.so.x versions
                      # in the LIB_DEPENDS

  * Extend 'make search' support to allow much more flexible searching
    From the PR:

    Besides the good old key and name variables, this patch adds
    support for path, info, maint, cat, bdeps, and rdeps, which match
    on the appropriate fields, plus their exclusion counterparts: xkey,
    xname, etc.

    Examples:

    Find all ports whose names contain "pear-" but not "html" or "http":

      make search name=pear- xname='ht(tp|ml)'

    Find ports whose names contain "pear-" and which don't have apache
    listed in build-time dependencies:

      make search name=pear- xbdeps=apache

    The positive variables (name, key, maint, etc) are AND-ed, their
    negative versions are OR-ed; in other words, matching any x-
    variable will cause the port to be skipped, mismatch on any non-x-
    variable will cause it to be skipped.

    Examples:

    Find ports that are both in the 'www' category and maintained by
    Thierry Thomas:

      make search maint=thierry@ path=/www/

    Find ports in the 'archivers' category that are either not orphaned
    or don't have "zip" in their names (contrived):

      make search cat=archivers xmaint=ports@freebsd xname=zip

    It is possible to select fields to display.

    Example:

    Find PEAR ports that don't build-depend on apache, displaying only
    Port:, Path:, and Info: lines:

      make search name=pear- xbdeps=apache display=name,path,info

    Case-sensitivity can now be turned of with icase=1.

    Example:

    Find ports with @freebsd.org maintainer addresses without the
    "proper" capitalization (@FreeBSD.org), display their paths and
    maintainer addresses:

      make search maint=@freebsd\\.org icase=0 display=maint,path

    The key and xkey variables can be limited in scope to displayed fields
    by setting keylim to 1.

    Example:

    Find ports that contain "apache" in either of the name, path, info
    fields, ignore the rest of the record (dependencies, maintainer
    address, etc):

      make search key=apache display=name,path,info keylim=1

    The following variables can be set e.g. in /etc/make.conf to
    control default search behavior:

      PORTSEARCH_DISPLAY_FIELDS?=name,path,info,maint,index,bdeps,rdeps
      PORTSEARCH_KEYLIM?=0
      PORTSEARCH_XKEYLIM?=0
      PORTSEARCH_IGNORECASE?=1

  * Extend USE_PERL5_BUILD and USE_PERL5 to add EXTRACT and PATCH
    dependencies

  * While building index, treat non-existent dependencies as fatal.
    Previously the error was being hidden by the stderr
    redirection.

  * Don't always retry BROKEN ports when package building (it is taking
    too much time to continually rebuild ports that are usually going
    to really be broken).  Set TRYBROKEN if you want to attempt a
    build of a BROKEN port.

	Over the past few weeks, we have been testing the next
	incarnation of ports/Mk/bsd.autotools.mk on the road to bringing
	at least some semblance of sanity back to this corner of the
	ports collection.

	By far and away the easiest way to see the changes will be to
	view the new file once committed, but here is a summary of the
	changes:

	1. USE_LIBTOOL, USE_AUTOCONF, USE_AUTOHEADER, USE_AUTOMAKE have
	been fully deprecated.  Ports attempting to use these variables
	after the commit will error out, and most obviously break INDEX
	generation, with a helpful error message.  Instead, ports must
	now specifically choose the version of any of these tools that
	they need with the corresponding USE_*_VER variables.  Note that
	these variables understand any and all versions of autotools ports
	in the tree, there is no longer a need to have specific version
	numbers hardcoded in the infrastructure of bsd.autotools.mk
	(as there is now).  In particular, this will immediately open up
	automake18 and autoconf259 for general use and beating.

	2. Similarly for WANT_LIBTOOL, WANT_AUTOCONF, and WANT_AUTOMAKE.
	Again, these have been fully deprecated, and the equivalent
	WANT_*_VER versions should be used.

	In order to preserve existing behavior for these variables, please
	note the 20040314 entry in ports/CHANGES for the appropriate
	version numbers to use for any ports in the GNATS queue.

	Both WANT_* and USE_* bring in the relevant tool as a build
	dependency, and set up a reasonably large number of variables
	pointing to the right programs to be using in the port.  The
	only difference at the moment, is that USE_* will run an extra
	autotools-related configuration step, whereas WANT_* merely
	requests the environment.

	3. The helper knob USE_LIBLTDL has been added which currently
	simply adds a LIB dependency on the libltdl port.

	4. Three new variables have been introduced,
	WANT_{LIBTOOL,AUTOCONF,AUTOMAKE}_RUN=yes.  These variables will
	do nothing by themselves (a Work-In-Progress), but if the
	appropriate autotool version is defined (either through
	WANT_*_VER or USE_*_VER), this will add the relevant dependency
	to RUN_DEPENDS.

	Steps 3 and 4 now essentially negate the need for any kind of
	direct dependency within a non-autotools port Makefile on
	devel/autoconf*, devel/automake*, devel/libtool*, and devel/libltdl.

	There has been a couple of bsd.java.mk tweaks and fixes.

	. Features from Stage 2 has been removed.  A port can no
	  longer use the JDK dependency features by setting JAVA_HOME.
	  Use JAVA_PREFERRED_PORT instead (see below).

	. The default JDK port now depends on OS version:
	  java/diablo-jdk13 for 4.x, and java/jdk14 for 5.x

	. It is now possible for the user (and the porters) to
	  define a list of preferred JDK ports to build and run ports.
	  The port will use the first JDK port from the list that
	  matches the requirements specified in the Makefile.
	  JAVA_PREFERRED_PORT contains a list of suitable JDK ports
	  (sorted by preference).  Names for JDKs may be found in
	  bsd.java.mk, listed in ${_JAVA_PORTS_ALL} (e.g.
	  "JAVA_PORT_NATIVE_BSDJAVA_1_4").

	. JAVA_PORT_VERSION is now set to the full version number
	  of the chosen JDK (e.g. "1.4.2").  Porters will find hints
	  regarding how to obtain the same behavior as before in the
	  header of bsd.java.mk.

AUTHOR:	gnome@FreeBSD.org
	When writing a port that uses GTK+ 2.X, you can now list the dependency
	with "USE_GNOME=gtk20" which is preferable to LIB_DEPENDS because the
	GTK+ library version only needs to be changed in bsd.gnome.mk.

	Please see http://www.FreeBSD.org/gnome/docs/porting.html for all
	the available GNOME components as well as detailed instructions on
	creating ports that use the GNOME infrastructure.

AUTHOR:	gnome@FreeBSD.org
	The glib20 and gtk20 ports were updated to 2.4.0.  This new version
	is completely source and binary compatible with the previous 2.2.x
	series.  However, certain API calls have been deprecated.  If your
	port defines the following macros, they may refuse to build with
	the new versions of glib20 and gtk20:

GTK_DISABLE_DEPRECATED
GDK_DISABLE_DEPRECATED
G_DISABLE_DEPRECATED

	The temporary solution is to either patch your port's Makefiles to,
	or use an in-place regular expression to remove these macros.  The
	more permanent solution is to wait until the port's authors update
	their code to use current API calls.

	There has been a big update to bsd.java.mk.  However, this update
	is mostly backwards compatible, so it shouldn't affect most java
	port maintainers.  There is some new functionality and minor
	changes worth documenting here though.

	bsd.java.mk now provides a new set of macros to be used by ports that
	require a JDK. When USE_JAVA is set, the following variables may be set
	in order to give to precision regarding the requirements of the port:

	. JAVA_VERSION
	  A list of space-separated suitable java versions for the
	  port. An optional "+" allows you to specify a range of versions.
	  (allowed values: 1.1[+] 1.2[+] 1.3[+] 1.4[+])
	  (NOTE: Used to be set by bsd.java.mk)
	. JAVA_OS
	  A list of space-separated suitable JDK port operating systems
	  for the port. (allowed values: native linux)
	  (NOTE: Used to be set by bsd.java.mk)
	. JAVA_VENDOR
	  A list of space-separated suitable JDK port vendors for
	  the port. (allowed values: freebsd bsdjava sun ibm blackdown)
	  (NOTE: Used to be set by bsd.java.mk)
	. JAVA_BUILD
	  When set, it means that the selected JDK port should be
	  added to build dependencies for the port.
	. JAVA_RUN
	  This variable works exactly the same as JAVA_BUILD but
	  regarding run dependencies.

	Here are some of the macros defined after setting USE_JAVA:

	. JAVA_PORT
	  The name of the JDK port (e.g. java/jdk14)
	. JAVA_HOME
	  The home of the JDK port in the local base
	. JAVA_PORT_VERSION
	  The version of the JDK port.
	  (NOTE: Used to be JAVA_VERSION, see above)
	. JAVA_PORT_OS
	  The operating system used by the JDK port.
	  (NOTE: Used to be JAVA_OS, see above)
	. JAVA_PORT_VENDOR
	  The vendor of the JDK port.
	  (NOTE: Used to be JAVA_VENDOR, see above)

	Plus many macros for the commonly used java executables:

		APPLETVIEWER, JAR, JAVA, JAVAC, JAVADOC, JAVAH,
		JAVAP, JAVA_KEYTOOL, JAVA_N2A, JAVA_POLICYTOOL,
		JAVA_SERIALVER, RMIC, RMID and RMIREGISTRY.

	bsd.java.mk 2.0 is mostly backward compatible with the previous
	version, save for the notes above and changed internal variables.
	Using the new features is strongly encouraged, since the old
	bsd.java.mk 1.0 features will be deprecated and may be removed in
	the future.

	You will find more detailed info (as well as a quick tutorial) at:

	The print/freetype2 port has been updated to 2.1.7.  This update
	changes some of the internal FreeType API.  Applications may need
	to be patched to support this new API.  If a source files includes
	freetype/freetype.h, make sure ft2build.h is included before
	freetype/freetype.h.  The proper way to do this is:

#include <ft2build.h>
#include FT_FREETYPE_H

	However, the following will work as well, but is deprecated:

#include <ft2build.h>
#include <freetype/freetype.h>

	USE_LIBTOOL, USE_AUTOCONF, and USE_AUTOMAKE are now considered
	deprecated, and will be removed on or around June 1st 2004.
	All ports should now choose the specific version of the tool,
	using USE_LIBTOOL_VER, USE_AUTOCONF_VER, and USE_AUTOMAKE_VER.
	The old "system default" behavior can be written as follows:

	Old			New
	USE_LIBTOOL=yes		USE_LIBTOOL_VER=13
	USE_AUTOCONF=yes	USE_AUTOCONF_VER=213
	USE_AUTOMAKE=yes	USE_AUTOMAKE_VER=14

	New variable MASTER_SITE_SOURCEFORGE_EXTENDED. It has the
	ten official sourceforge.net download mirrors, whereas
	MASTER_SITE_SOURCEFORGE only has five. To check if your
	port is mirrored there, go to
	<http://prdownloads.sourceforge.net/${MASTER_SITE_SUBDIR}/>
	click on ${DISTFILES} and you'll see five or ten mirrors,
	corresponding to the variables above.

	The default version of Ruby is now 1.8 on all platforms
	including the i386.

	Users on the i386 platform need to follow the instructions
	described in the UPDATING file to cope with this upgrade.

	Next time ruby is major upgraded, you won't need to do this
	kind of messy work because some subtle changes have been made
	to the ruby port infrastructure to make it easier to handle
	multiple versions of ruby.

AUTHOR:	gnome@FreeBSD.org
	Mozilla will now default to using GTK2, and will only compile
	against Gtk+-1.2 if explicitly requested.  This is in exact
	opposite to the old behavior.

	The valid values of WITH_MOZILLA are now:
		mozilla			(www/mozilla, GTK2)
		mozilla-devel		(www/mozilla-devel, GTK2)
		mozilla-gtk1		(www/mozilla-gtk1, GTK1)
		mozilla-devel-gtk1	(www/mozilla-devel-gtk1, GTK1)

	As before, WITH_MOZILLA can be set in /etc/make.conf, but doing
	so is not advised unless you desire the development versions.
	GTK2 browsers will automatically compile against GTK2 mozilla,
	and GTK1 browsers (galeon1, galeon1, and galeon1) will
	automatically compile against GTK1.

	Again, the only people who will need to take action are those
	who desire development versions (which are inactive at this time
	anyway).  Those who want GTK1 mozilla-devel must set
	WITH_MOZILLA=mozilla-devel-gtk1 or they will be pleasantly
	surprised with their very own GTK2 installation on the next
	update.

	WITH_MOZILLA=mozilla-gtk2 and WITH_MOZILLA=mozilla-devel-gtk2
	are still honored for the time being, but their use is
	now deprecated.  Any new ports are not required to consider
	their values, and so eventually WITH_MOZILLA _will_ have to
	be changed.

	Hopefully galeon2 can catch up to peoples' expectations from
	galeon1 soon, and we can remove the GTK1 ports altogether.

20040204:
AUTHOR:	portmgr@FreeBSD.org
	The bsd.php.mk file has been moved out of the lang/php4 port
	into the Mk directory.  This will make it much easier to include
	PHP support in PHP-dependent ports.  Instead of including
	bsd.php.mk directly, a port can simply set USE_PHP=yes, and the
	ports system with Do the Right Thing.

	All trailing whitespace has been removed from bsd.port.mk.

	Enhance the new OPTIONS code by only including saved options if
	the port defines OPTIONS, attempt to use LATEST_LINK as the
	unique name for a port (fall back to ${PKGNAMEPREFIX}${PORTNAME}
	otherwise), bring the ===> messages in line with the existing
	ones by using PKGNAME instead of PORTNAME, use PKGNAME in the
	dialog, use ECHO_CMD instead of ECHO_MSG to write the
	OPTIONSFILE, display a message during compilation indicating
	that user-specified options have been found, and make the output
	of the showconfig target a little more user-friendly.

	A new USE_ICONV macro has been added that takes the place of an
	explicit LIB_DEPENDS on converters/libiconv.  This will help
	with future shared lib version bumps.

	A new USE_GETTEXT macro has been added that takes the place of
	an explicit LIB_DEPENDS on devel/gettext.  This will help with
	future shared lib version bumps.

	Module::Build is a system for building, testing, and installing
	Perl modules.  It will eventually replace the obsoleted
	ExtUtils::MakeMaker.  Many new Perl modules have already
	switched to using Build.PL instead of Makefile.PL.  To
	facilitate building those modules, a new PERL_MODBUILD macro has
	been added.  Use that in place of PERL_CONFIGURE when porting
	Perl modules that make use of the Module::Build framework.

	Certain ports want to check for the availability of SDL
	libraries before including them.  This change adds a new
	WANT_SDL macro similar to WANT_GNOME.  By setting this, the
	porter indicates that her port can optional use SDL if present
	on the system.  WANT_SDL should be defined _before_
	bsd.port.pre.mk is included.  After including bsd.port.pre.mk,
	the list of available SDL components will be returned in the
	HAVE_SDL macro.  For details on how to process this component
	list, refer to bsd.sdl.mk.

	The OpenBSD and NetBSD projects diverged from the FreeBSD ports
	tree years ago, and it no longer make sense to include obsolete
	references to incorrect paths in the FreeBSD ports system.  This
	change removes the NetBSD and OpenBSD PORTSDIR compatibility
	bits from bsd.port.mk.

	The comment for PKGDIR read, ``A direction containing any
	package creating file.''  The word ``direction'' should be
	``directory.''  This has been fixed.

	A new DIRNAME macro has been added that points to
	/usr/bin/dirname.  All direct use of dirname in ports can be
	switched to this macro.

	Direct use of commands dirname, id, and rm have been corrected
	to use their macro equivalents instead.  Some useless ${HEAD}
	-n 1 statements have been removed.  A strange comment in the
	do-install target and an out of place ``fi'' have been fixed as
	well.

	On 5-CURRENT after the 5.2-RELEASE split, the default Perl
	version has been updated from 5.6.1 to 5.8.2.  As well, some
	Perl definitions in bsd.port.mk have been moved to their correct
	locations which corrects the PERL_LEVEL definition.

	The following optimizations have been added to the ports system
	to speed up recursive operations such as make describe, make
	index, make ignorelist, etc.  bsd.gnome.mk is now only included
	if a port defines USE_GNOME, WANT_GNOME, and/or USE_GTK.  More
	variables are cached and passed down through bsd.port.subdir.mk.
	Perl is no longer invoked when a simple ``echo'' will do.  More
	subshell variable assignments have been hidden behind
	conditionals so that the commands are not spawned every time.
	Finally, dependency lists are only constructed if ports actually
	declare dependencies.  These optimizations give make index
	approximately a 43% speedup.

	If CPUFLAGS is not defined (this _CPUCFLAGS is empty), trying
	to remove _CPUCFLAGS from CFLAGS will result in an error.  This
	change fixes that.

	On recent versions of 5.X, /etc/rc.subr exists, and there is no
	reason to install another copy in ${LOCALBASE}/etc.  The reason
	this was ever done was to workaround some build issues on bento.
	However, testing OSVERSION seems to work in spite of those build
	issues.

	The ports system now supports MySQL 3.23, 4.0, 4.1, and 5.0.
	Also, the ability to scale to newer versions was also but in
	place.

	An .endif comment indicated that the .if block checked
	WANT_MYSQL when, in fact, it was checking WANT_MYSQL_VER.  This
	has been corrected.

	The PTHREAD{CFLAGS,LIBS} macros have been made overridable on
	all versions of FreeBSD to allow for alternate threading
	implementations (e.g. -lc_r, -lthr, -mt, etc.).  The default
	threading library has been changed to -lpthread from -lc_r on
	-CURRENT.

	The new SIZE support broke distfiles fetching on FreeBSD < 4.8.
	On those versions of FreeBSD, the SIZE distfile attribute is now
	ignored.  Also, defining DISABLE_SIZE in, for example,
	/etc/make.conf, will ignore the SIZE attribute on all versions
	of FreeBSD.  This is useful with alternate values for FETCH_CMD.

	A new vulnerabilities database has been added to the ports
	system in order to keep more accurate, up-to-date, track of
	security vulnerabilities.  The ports system now knows how to
	query that database and dynamically prevents the installation
	of vulnerable ports.

	In order to allow for more rapid development of the package
	tools, the ports system will prefer to use pkg_* tools found in
	${LOCALBASE} over those in the base system.  However, all PKG_*
	macros are still overridable.

	A new physical category, net-mgmt, has been created to house
	network management ports.

	The /var/db/port.mkversion file never really took off, and is
	now very obsolete.  Replace the code used to generate and check
	this file with a simple OSVERSION check.  The ports system now
	requires FreeBSD 4.3 or higher.

	The last round of bsd.*.mk changes broke ports that had
	duplicate distinfo entries (e.g. linux_base).  This is now
	fixed.  Along with this fix, only distfiles with a bad checksum
	will be refetched, where as distfiles missing from distinfo will
	not be refetched.

	The PLIST_{DIRS,FILES} macros were passed to the final package
	list unchanged by PLIST_SUB.  This is not always desirable.
	Now, those macros are passed through PLIST_SUB.

	The previous OPTIONS code assumed users would be running port
	build as root.  If this was not the case, OPTIONS configuration
	would fail.  Now, the bits of the config and rmconfig targets
	that require write access to system directories are run under
	SU_CMD.

	The makesum target will now add a SIZE attribute for each
	distfile by default.  This can be overridden by defining NO_SIZE
	in a port's Makefile.  Note: this could probably be expanded to
	omit SIZE attributes for specific distfiles in the future.

AUTHOR:	trevor@FreeBSD.org
	SIZE lines in distinfo files:  if you set USE_SIZE when you do "make
	makesum", the byte sizes of the distfiles will be listed in the
	distinfo file. Then, if a distfile is replaced on its master site with
	one of a different size than that listed, "make fetch" will fail with a
	"size mismatch" error before downloading the file and the user will be
	asked to fetch the file by hand. Also, a user will know the size of
	the distfiles before fetching and decide to fetch later.
