    - Added new config file archive_sites.conf, which can be used to configure
      additional archive download sources. Each source has an associated
      archive type; portarchivetype is now only used when creating archives
      locally. Sources also have an associated prefix, applications_dir and
      frameworks_dir, and if any of these do not match the current values, the
      source is not used. (jmr in r91009)

    - Xcode 4.3 support: Search harder for developer directory; advise user to
      run xcode-select when necessary, searching for Xcode and suggesting
      xcode-select commands.
      (jberry, jmr in r89970,r89971,r89972,r89996,r89999,r90003,r90005-r90009,
      r90018-r90019,r90024,r90031)

    - warn about non-existing developer_dir when it's set in macports.conf
      (cal in 90802)

    - port automatically installs bsdmake when there's no bsdmake in $PATH and a
      port sets build.type bsd (#33355, cal in r90650)

    - Added -W option for reinplace that sets a base directory that all file
      arguments are interpreted as being relative to. (raimue in r90610)

    - Added macports.conf options 'host_blacklist' and 'preferred_hosts', used
      for indicating lists of download hosts that should not be used or should
      be used preferentially, respectively. These override the usual ping time
      check. Ping times are also now cached for 24 hours. (jmr in r89459)

    - Added 'rev-upgrade' action checking for broken linkage and rebuilding
      ports containing broken files. Made rev-upgrade run automatically after
      each upgrade or install.
      (cal in branch gsoc11-rev-upgrade, merge in r88376, also cal, raimue, jmr
      in r88377,r88411,r88441,r88511,r88666,r88732,r89180,r89659,r89661,r90102,
      r90381)

    - Added options controlling rev-upgrade behavior to macports.conf
      (jmr, cal in r88725,r88794,r89189)

    - port livecheck regex finds multiple matches on the same line
      (raimue in r88031)

    - Several improvements to port lint:
      licenses, subversion properties, maintainer addresses
      (#30194, snc, raimue in r85929, r86016, r89428, r89610)

    - Added license_noconflict option to specify dependencies for which the
      maintainer has manually checked license compatibility and wishes to
      overrule the conservative automated checks. (jmr in r89004)

    - Xcode 4.3 support: Use xcrun -find to find xcode compiler if it's not
      found in /usr/bin.
      (jberry, jmr in r88540,r88541,r88546,r88777,r88779,r88787,r89359,r89984,r90028)

    - Added options compiler.blacklist, compiler.whitelist, and
      compiler.fallback; to allow blacklisting, whitelisting, and setting the
      fallback order for configure.compiler values, respectively.
      (#30041, jmr in r88676)

    - Fix sync with subdirectory of Subversion 1.7-format working copy
      (#33573, jmr in 86872)

    - Fixed conflicts not being checked for when installing ports that have no
      dependencies. (#31571, dports in r85382)

    - dmg postflight: quote all paths to handle the increasingly frequent
      occurrence that $HOME contains spaces (#33583, ryandesign in r84345)

    - dmg postflight: adjust wording of some messages (ryandesign in r84344)

    - The deprecated Portfile options svn.tag, distcheck.check and
      livecheck.check have been removed. (raimue in r82763)

    - Implement new option-replace using lsearch/lreplace. The old behavior is
      deprecated for option-replace with only one argument, but can still be
      found in option-strsed.
      (raimue in r82760, r82761)

    - Added 'buildfromsource' macports.conf setting, which allows permanently
      selecting the behaviour of the -s or -b option. (jmr in r81540)

Release 2.0.4 (2012-02-25 by jmr)
    - Added -locale option for reinplace (jeremyhu in r89839)

    - Xcode 4.3 support: Change home directory for MacPorts user to
      ${prefix}/var/macports/home.
      (jberry, jmr in r89988, r89993, r90002, r90010, r90011)

    - set env(HOME) to ${workpath}/.home when building ports
      (#31827, jmr in r89994, r90004)

    - Fix use_xmkmf to honor xmkmf.env for its make Makefiles phase
      (#31504, jeremyhu in r89537, r89538, r89539)

    - Added configure.cxx setting when configure.compiler is apple-gcc-4.2
      (jeremyhu in r80248)

    - Xcode 4.3 support: added packagemaker_path macports.conf setting
      (jmr in r90058)

    - Resolve ambiguity in selection in portlists
      (jberry in r88179, r88185)

    - Xcode 4.3 support: updated default developer_dir location for 4.3
      (jmr in r90016)

    - Xcode 4.3 support: use compilers in /usr/bin instead of developer_dir
      when possible, as the latter has proven to be volatile.
      (jmr in r90015)

    - Xcode 4.3 support: updated SDK paths for 4.3 (jmr in r90000)

    - Work around broken FTP proxy support in some versions of libcurl
      (jmr in r84351, r88045)

Release 2.0.3 (2011-09-05 by raimue)
    - Fix a regression introduced in 2.0.2 when fetching with a VCS
      (#31073, jmr in r83471)

Release 2.0.2 (2011-09-01 by jmr):
    - Messages recommending running selfupdate will no longer be printed when
      selfupdate is being run. (#23094, jmr in r83270, r83391)

    - The PortIndex will not be regenerated during selfupdate when base is
      outdated. This avoids failure to index ports that use features only
      available in the current version. (#30739, jmr in r83271)

    - Fixed build failures when the TMPDIR environment variable is set to a
      directory that is not writable by the macports user.
      (#30749, jmr in r83267)

    - Fixed error when checksumming distfiles with names containing spaces.
      (#28568, jmr in r83149)

    - The uninstall and deactivate actions now sort the port list so that
      dependents are processed before the ports they depend on.
      (#8431, jmr in r82947)

    - Fixed an issue where a non-universal version of a port could be
      installed as a dependency as well as the universal version, with
      unpredictable results, when some ports in the dependency graph needed
      the universal version but others didn't. (jmr in r82924)

    - Now using a temp dir inside ${prefix} when activating, as /tmp or
      /var/folders may be on a different volume. (jmr in r82767)

    - Fixed extracting portfile-only archives. (#31033, jmr in r81830)

    - Fixed adduser and addgroup procedures not re-dropping privileges when
      done. (jmr in r81630)

    - Fixed error activating ports with names containing the string "cpio".
      (#30532, jmr in r81577)

Release 2.0.1 (2011-08-02 by jmr):
    - Fixed errors when installing some archives built on a case-sensitive
      filesystem onto a case-insensitive one. (#30373, jmr in r81562)

    - Fixed users created by MacPorts showing up in the GUI in some places on
      Lion. (#30168, jeremyhu in r81558)

    - Added replaced_by pseudo-portname selector. (afb in r81475)

    - Added progress output to port image conversion script.
      (#30347, jmr in r81464)

    - Now doing a better job of avoiding UID conflicts with non-local users
      when creating the 'macports' user. (#30464, jmr in r81414, r81415) Also
      improved Tiger compatibility in this area. (jmr in r81454, r81467)

    - Fixed 'port selfupdate' exiting with non-zero status after installing a
      new version of base. (jmr in r81371)

    - Added --subports to options accepted by 'port info'. (jmr in r81234)

    - Fixed incorrect info sometimes being added to PortIndex entries when
      using subports. (#30463, jmr in r81361)

    - Fixed descriptions not being shown for default variants. (jmr in r80971)

    - Fixed 'port variants --index'. (jmr in r80969)

Release 2.0.0 (2011-07-22 by jmr):

    - Multiple ports can now be defined in one Portfile using the 'subport'
      procedure. This reduces code duplication when several ports use very
      similar code. (jmr in r78062)

    - Privilege dropping is now on by default. The runtime user can be changed
      when building from source but defaults to 'macports'; this user is
      created at install time. (jmr in r79025)

    - Fetching from some extremely slow or partially unresponsive servers
      should now time out as expected. (raimue in r71038)

    - The registry is now "vacuumed" (compacted/defragmented) after
      uninstalling ports. (jmr in r70608)

    - Downloaded archives are now checked for integrity using digital
      signatures. Sync and selfupdate can also use a signed tarball. New
      pubkeys.conf file allows configuring keys to trust.
      (jmr in r68996, r79093)

    - Added 'actinact' pseudo-portname that expands to installed ports with an
      active version and at least one inactive version.
      (#27666, jmr in r79421, based on patch from gmail.com:ww.galen)

    - Added --size option for 'contents' action that makes it print the size
      of each file. (#27245, jmr in r79365, based on patch from
      gmail.com:ww.galen)

    - Added 'space' action to show the disk space used by ports' active files.
      (#27244, jmr in r79349, based on patch from gmail.com:ww.galen)

    - Actions can be abbreviated to an unambiguous prefix of the full name.
      (#27242, patch from gmail.com:ww.galen committed in r79259)

    - Fixed error when activating ports whose version contains an underscore
      followed by an integer and a dash. (#28084, jmr in r79167)

    - Deactivating a port that has dependents no longer needs to be forced
      when the dependents are all inactive. (#29505, jmr in r78086)

    - New option 'add_users' has been added. Setting it will ensure that the
      listed users are created before all operations that may require them to
      exist. (#11563, jmr in r78660)

    - 'port info --index' should be much faster and will work with the
      'current' pseudo-port provided the port has been indexed.
      (#13673, jmr in r78621)

    - Relocation is explicitly disabled when building pkgs on 10.6, so Apple's
      Installer won't attempt to overwrite other copies of the same software
      not installed by MacPorts. (#25174, jmr in r78178)

    - Non-Darwin platforms can once again build base against OpenSSL for
      checksum support. (#26813, afb in r77865)

    - It is now safe to set svn.post_args, rather than that option being
      reserved for svn.url. (#27454, jmr in r73825)

    - Variants specified when running 'port mpkg' are now set in the
      dependencies as well. (#27231, jmr in r73303)

    - Fixed various issues with privilege dropping.
      (#26899, jmr in r69453 etc.)

    - Trace mode no longer fails on 10.6. (#21582, jmr in r74318, r74369)

    - Ports that create StartupItems (aka launchd plists) should now be
      installable by unprivileged users. (#10879, jmr in r66700, r75143)

    - Fixed incorrect output from 'port dependents' when using newer SQLite
      versions. (#27506, patch from gmail.com:mmpestorich committed in r76827)

    - The flat registry format is no longer available. Setting portdbformat to
      'flat' in macports.conf will result in the sqlite registry being used.
      (jmr in r77681)

    - Port images are now stored as archives. Archive mode is now effectively
      always on. Among other benefits, this fixes some bugs with the handling
      of hard links installed by ports (e.g. #13601).

      Direct mode is no longer available. Existing port image directories, and
      installed files for direct mode, will be converted to archives when
      upgrading.

      (#19458, branch by blb, merged by jmr in r77511)

    - master_site_local, patch_site_local, and archive_site_local can be set
      in macports.conf, with the same effects as the corresponding environment
      variables. (jmr in r74924)

    - Added 'logfile' action that prints the path to a port's log file.
      (jmr in r74655)

    - Computing large dependency trees that contain the same port(s) multiple
      times should be considerably faster. (jmr in r73133)

    - New configure.compiler options: macports-gcc-4.6, macports-llvm-gcc-4.2,
      macports-clang (jmr in r71487; mfeiri in r72936, r72937)

    - Add '-n' option to reinplace (#26406, ryandesign in r73227)

    - Add new ccache_dir and ccache_size options, default path is
      ${portdbpath}/build/.ccache and a size of 2 GB.
      (raimue in r71604, r71606)

    - Add 'system -W path' which changes to the given directory before
      executing the command.
      (raimue in r71380, r71389)

    - Add -w to build.cmd and destroot.cmd if using gnumake
      (raimue in r71370)

    - Add livecheck.ignore_sslcert; setting fetch.ignore_sslcert does no
      longer apply to livecheck. distcheck now respects fetch.ignore_sslcert.
      (#17063, raimue in r70975, r70979, r70982)

    - Add SHA256 checksums in addition to MD5, SHA1 and RIPEMD160.
      (afb in r57888, r57913; snc in r68955)

    - Add @pkgdep lines to archives, with build-time dependencies.
      (afb in r76919)

Release 1.9.2 (2010-11-07 by jmr):

    - Added more locking to avoid TOCTOU errors when running multiple port(1)
      instances (#19935, jmr in r70174)

    - Fixed -q not suppressing output from 'port lint' (#25880, jmr in r70163)

    - Added a helpful message when there is a checksum mismatch and the
      distfile appears to incorrectly be a HTML document (#25128,
      ryandesign/jmr in r70143)

    - Now checking early on if there are sufficient privileges to install,
      and failing before building anything if not (#25671, jmr in r70135)

    - Avoided possible failure when the -u option is used when upgrading a
      port that is marked as being replaced by another (jmr in r69022)

    - Using the platform-specific PortIndex when syncing using a daily tarball
      (jmr in r68786)

    - Fixed failures when fetch target is run without root privileges and the
      port is then installed with them (#25418, #25937; jmr in r69334, r70271)

    - Fixed upgrading ports where the new version differs from the old version
      only in epoch (jmr in r69436)

    - Fixed [un]setrequested when using the flat registry format
      (#26352, jmr in r69387)

    - Fixed checking for conflicting ports before installation
      (#25386, jmr in r69105)

    - Now gracefully handling distfiles that use a tag that is not
      associated with any sites (#25332, jmr in r68965)

    - Fixed running 'port deps' on multiple ports, and changed its output
      format back to how it was in 1.8 (#25324, jmr in r68950)

    - Fixed premature privilege dropping (#25331, jmr in r68952)

Release 1.9.1 (2010-06-18 by jmr):
    - Fixed a couple of problems with new 1.9 features when using the flat
      registry format (jmr in r68910, r68913)

    - Ports using the replaced_by option will once again be deactivated when
      an upgrade is performed on them (#25270, jmr in r68872)

    - Fixed the possibility of some empty directories being left behind when
      a port is deactivated (#25268, jmr in r68864)

    - Fixed failure to detect conflicts with files that are not provided by
      a port before activation starts (#25255, jmr in r68849)

    - Fixed problems with distfile names containing spaces (#25245, #25246;
      jmr in r68816, r68817)

    - Fixed a problem with uninstall when using direct mode, and started
      running pre/post activate and deactivate procedures when installing and
      uninstalling in direct mode, respectively (#11562, jmr in r68697)

    - fixed a crasher that affected Tiger (#25194, jmr in r68675, r68680,
      r68691)

Release 1.9.0 (2010-06-08 by jmr):

    - It is no longer possible to use include statements in Portfiles
      (raimue in r68206)

    - Command line options can be abbreviated if unambiguous
      (raimue in r66837)

    - Added a new variable 'os.subplatform'. When os.platform is darwin, the
      subplatform is either 'macosx' or 'puredarwin'.

    - 'platform' no longer creates a variant, instead it executes the code in
      the body immediately if the current platform matches the one specified.

    - Using a Portfile with a modification date in the future now causes an
      informative error early on, instead of just discarding the workdir at
      the start of every phase. (#24717, raimue in r65246)

    - Fetching from servers that require a cookie to be set now works.
      (#24584, raimue in r66785)

    - Fixed an error when everything is deleted from the patchfiles list.
      (#24178, raimue in r65243)

    - Added 'license:' pseudo-port selector. (#24123, perry in r65033)

    - Added new fetch.type 'bzr'. (#23436, perry in r65096)

    - Added 'rdeps' and 'rdependents' actions, recursive versions of 'deps'
      and 'dependents' respectively. Also added 'depof:', 'rdepof:',
      'dependentof:' and 'rdependentof:' pseudo-port selectors, for specifying
      the ports that are dependencies or dependents of the given port.
      (#22346, jmr in r65858/r66198)

    - Updated the description of the search action in the port(1) man page.
      (#23749, jmr in r66670)

    - Dry-run now uses /dev/null as the statefile, which prevents a couple of
      problems involving locking and variant checks.
      (#21794, #21962; jmr in r66921)

    - The list of dependencies to be installed is now displayed immediately
      after computing them. (#21540, jmr in r66321)

    - The quick index is now reloaded after syncing in interactive mode, which
      prevents errors due to it not matching the updated PortIndex.
      (#20874, jmr in r66319, refinement of patch from carrel.org:edward)

    - The architectures of dependencies are checked when installing a port. If
      a dependency does not provide the required arch(s), it is rebuilt with
      +universal if that is possible and will help, otherwise the install fails
      and an error message explains why. (#20728, jmr in r65087)

    - New supported_archs option allows ports to indicate which architectures
      they can be built for. The default values of configure.build_arch and
      configure.universal_archs change based on this list. Set this to
      'noarch' if a port installs only architecture-independent files.
      (#20739, jmr in r64372/r64945)

    - Declaring a variant that requires one or more other variants will now
      correctly set the required variants, so they can be checked with
      variant_isset. (#19224, jmr in r66642)

    - 'port outdated' now indicates the reason why a port that appears to have
      the same version as that in the tree is considered outdated. Possible
      reasons are that the epoch is higher, or the installed version was built
      on a different OS version. (#19138, jmr in r64960)

    - Distfile names are now percent-escaped in the download URLs when needed.
      (#18736, jmr in r66794)

    - buildnicevalue is now applied to configure and destroot commands, and to
      build commands with unusual names. (#18304, raimue in r65076/r65808)

    - Removed hardcoded /opt/local prefix from the base dmg resources.
      (#17633, jmr in r66776)

    - Fixed an error that occurred when archive mode was enabled but
      ${prefix}/var/macports/packages did not exist. (#17579, jmr in r66775)

    - Syncing rsync sources now tries to get a platform-specific version of
      the PortIndex from the server, and skips this if the local copy is less
      than a day old. All sync methods now update the PortIndex at the end.
      (#17157, jmr in r66846/r67207)

    - portindex(1) now skips parsing Portfiles whose modification time is
      older than the current PortIndex, instead reusing the existing entry.
      (#16235, jmr in r66845)

    - Added a 'requested' flag to the registry that indicates which ports were
      installed explicitly (as opposed to as a dependency of something else).
      This enables the new 'requested', 'unrequested' and 'leaves' pseudo-
      ports, as well as the --follow-dependencies option for uninstall.
      The setrequested and unsetrequested actions will set and clear the flag,
      respectively.
      (#15260, jmr in r64517, r64663, r65546, r66037, r66200, r66215)

    - The macports1.0 directory is now installed to
      ${prefix}/share/macports/Tcl rather than /Library/Tcl. A symlink will be
      installed in the old location if there is nothing there already, so
      'package require macports' will still work in tclsh.
      (#12943, jmr in r65055)

    - Added warning and error messags when Xcode is old enough to cause
      problems or too old to use at all, respectively. (#12794, jmr in r66771)

    - Removed the rather outdated copy of sqlite3 from the source tree, made
      the sqlite3 directory configurable, and added defaults for non-darwin
      platforms. (#12231, jmr in r64358/r64363)

    - There is a new 'archivefetch' target which is run before unarchive when
      archive mode is enabled, and attempts to download the archive from a
      server. There are currently no sites configured to download from (these
