Changes since beta2:

• Version number only.

Changes since beta 1:

• port migrate syncs the ports tree before reinstalling ports.
• Various fixes and improvements to error handling and reporting in the snapshot and restore code.

Changes since 2.9.3:

• port space no longer overcounts the space used by ports that
  install links. (#66526, jmr in 11662bd)

• The number of outdated ports is printed after running
  port selfupdate. (#33820, thelastlin in 4ae6d98)

• port selfupdate now checks whether MacPorts base is outdated by
  downloading a small file, and only downloads and extracts the
  source code (via http(s)) if a new version needs to be installed.
  Integrity of the source is checked using OpenBSD's signify(1).
  The old rsync method is used as a fallback if the new method fails.
  (#38265, cal in dd3acc4)

• Line continuation is supported in macports.conf by ending lines
  with a backslash. (jmr in b86ef1e)

• Ports' files are now activated using clonefile() when on a
  filesystem that supports cloning (such as APFS). This should
  perform better and use less storage for active ports. Port images
  are stored as directories rather than archives in this case. A
  portimage_mode option has been added to macports.conf to
  enable changing which method is used. (#69555, jmr in 4504942)

• The middle part of bin:, lib:, and path: depspecs is no longer
  interpreted as a regex. This was mostly undocumented, almost
  never used, and made it difficult to use paths containing
  characters with special meaning in regexes.
  (#69585, jmr in e0c1226)

• Added port migrate action, which can be used after moving to a
  new major OS version or CPU architecture to reinstall MacPorts
  base and installed ports if needed. (umeshksingla in 6e2f453,
  cal in 3f83ad1, 4317a32, f40f655, 72478b1 etc.)

• Added -t and -N options to the default patch.pre_args, to prevent
  patch(1) on recent macOS versions from silently reverse-applying
  already-applied patches. (vallon in b1f59d8)

• Updated the bundled Tcl to 8.6.14. (jmr in bc46d68)

• Added test.asroot option. (jmr in 6f0de6c)

• Prevented port rdeps --full from looping infinitely when there
  are circular dependencies. (#62711, jmr in 49df406)

• Performance improvements for many operations, particularly
  boolean expressions and Portfile parsing. (jmr in a28e81c,
  169b1ed, 2f3d072, c97e75d, 341d9a0, 46bc1af, etc.)

• Add progress bars to slow activation and deactivation operations.
  (cal in b78e320, 5e669e4, 31c2851, cb33058, effd435)

Changes since 2.9.2:

• Fixed error due to insufficient privileges to create the work
  symlink in some circumstances. (jmr in 51511c8)

Changes since 2.9.1:

• Fixed built-in architecture test failing on unreadable files.
  (#69478, jmr in e3468c5)

• Fixed some issues that could occur if settings like 'prefix'
  contained symlinks, by fully resolving and normalizing paths read
  from the config file. (#69327, jmr in b69f0cf)

• Fixed privileges sometimes not being dropped for test target.
  (jmr in d304c0a)

Changes since 2.9.0:

• Fixed installation of unneeded build-time dependencies when using
  source-only mode. (cal in 5988c00)

Changes since 2.8.1:

• Upgrade will now update registry metadata if needed for ports
  that are not outdated. This should hopefully cut down on revision
  increases requiring a rebuild just to do things like add or
  remove dependencies. (jmr in bec110b)

• Added new option startupitem.logfile.stderr.
  (#67955, mascguy in e70a512)

• Many single-letter command line options should now work when
  given after the action name, and apply only to that action. A few
  like -N can't easily be turned on and off internally, so if in
  doubt, keep putting single-letter options before the action.
  (jmr in aec0601)

• Ports that set platforms containing any are now not considered
  outdated after major OS updates. (#68256, jmr in 1b4db00)

• Dependencies installed for the first time when upgrading a port
  no longer inherit all variants from the dependent port. Arch
  checking is now done in this case so +universal is added to the
  dependency iff needed. (#67637, jmr in 7be167c)

• Prevented rev-upgrade from complaining about weakly-linked libs
  that are not present. (#52700, chrstphrchvz in 77e333a)

• Avoid installing build-time dependencies when force-upgrading an
  installed port for which a binary archive will be used.
  (#67017, jmr in a9597dc)

• Fixed error when running upgrade with -R and -u options.
  (#68019, jmr in 980a5c1)

• Fixed rev-upgrade potentially trying to access registry entries
  that have been uninstalled as a result of a rebuild.
  (#66186, jmr in 1abd73a)

• Fixed missing make command potentially causing some ports to fail
  to parse. (#60881, jmr in 1b4e6a1)

• Prevented destroot.keepdirs from creating files outside the
  destroot. (#55673, jmr in 8db11c8)

• Running port install on a port that is already installed will
  set the requested flag for that port. (#55085, jmr in 7ed853d)

• Fixed trace mode on Intel macOS 13. (#66358, cal in 4a1b0c7)

• Fixed incorrect trace mode handling of setuid/setgid binaries.
  (cal in 9cc9afc)

• Fixed the deactivate and uninstall actions sometimes not handling
  multiple ports in correct dependency order if one or more of them
  was specified with non-canonical case. (#60446, jmr in 772a9cc)

• Fixed port names that differ only in case not being considered
  to be the same when evaulating boolean expressions.
  (#50518, jmr in bd02a2f)

• Fixed some issues that could occur in the unusual case that a
  mirror has an archive but not its corresponding signature.
  (jmr in a774938, f7828b8)

• If the macports user has an incorrect home directory set somehow,
  the installer should now fix it. (#49101, jmr in 128e8ce)

• Skip vacuuming the registry database on shutdown (after
  uninstalling one or more ports) if it would not save significant
  space. (jmr in c82a269)

• Clean up the SQLite write-ahead log file when closing the
  registry. (jmr in 9bb06b9)

• Added a simple default test phase for all ports, which currently
  just checks the architectures of installed files. test.run yes
  enables the tests defined by the Portfile, as before. It should
  always be safe to run port test now, and if it fails it means
  a test didn't pass. (jmr in ddc2655)

• Using multiple threads for portindex. (jmr in f00bf80)

Changes since rc1:

• Fixed error when running port diagnose. (#69126, jmr in f37bf45)
