MacPorts 2.7.0-rc1

Changes since beta2:

• Fixed build failure on <= 10.6.
• Adjusted minimum compiler version for C++17.
• Using -j1 for the benefit of ninja when build.jobs is 1 (instead of no -j option), and setting use_parallel_build no changes the value of build.jobs to 1 rather than omitting the -j option.
• Checking some more logs for implicit function declarations.
• Printing some more possibly helpful log locations when configure fails.

MacPorts 2.7.0 beta 2

Changes since beta1:

• Fixed an error that could occur when applying the previously requested variants when upgrading. (#62751)
• Fixed progress bar width when COLUMNS is not set in the environment.
• Fixed inability to read the registry database without write permission when using newer SQLite versions.

Known issues:

• The change committed as 4f276ab needs to be applied on 10.6 and older to successfully build base against the system SQLite.

MacPorts 2.7.0 beta 1

Changes since 2.6.4:

• The platforms option now has a default value of darwin.
  (jmr in d918190)

• Fixed incorrect versioning assumptions that led to being unable
  to find the right SDK on Big Sur. (#61866, jmr in 8aa347e)

• Fixed installer incorrectly setting DISPLAY in the user's shell
  config on Big Sur. (#61649, jmr in 4ce1e96)

• Fixed crash in rev-upgrade when MacPorts was built against the
  macOS 11 SDK and run on 10.15. (#61540, jmr in 23f2aa3)

• Fixed minimum compiler version selected when C++14 and
  thread-local storage are required.
  (#61418, chrstphrchvz in 618d036)

• Enabled write-ahead logging when using SQLite 3.22.0 and later,
  and enabled the fullfsync pragma, which should make the database
  even more resilient against power failures and the like.
  (#61154, jmr in 5779dbc)

• Fixed svn fetch with newer Xcode versions that no longer provide
  svn (but do ship a /usr/bin/svn stub) by always using the
  subversion port. (#60854, jmr in 4acfd68)

• Logs now explicitly mention the port's version, revision, and
  active variants. (#59643, jmr in d484695)

• Improved error reporting when circular dependencies are present
  when installing or upgrading ports. (#59289, jmr in cea9833)

• The universal variant is removed if it is not possible to build
  for two or more architectures. (#57133, jmr in fcff138)

• New universal_possible variable can be checked to see if
  universal building is possible. (jmr in e356e1e)

• Fixed error when choosing the currently active version when
  interactively prompted to pick a version by port activate.
  (#56817, jmr in 5f41bb4)

• Configuring MacPorts base with --with-no-root-privileges now
  also defaults to --without-startupitems. (#56743, jmr in a18eb94)

• Rev-upgrade now makes it more obvious when a port is considered
  broken because of using the wrong cxx_stdlib.
  (#56629, jmr in 00a2631)

• Fixed missing error message when the sync portion of selfupdate
  fails. (#56549, jmr in 8f4b9e5)

• When installing a port, the variants that are requested by the
  user (either on the command line or via variants.conf) are now
  recorded in the registry in order to distinguish them from
  default variants chosen by the port. When upgrading, only the
  requested variants from the previous version, rather than all its
  active variants, are considered when deciding which variants to
  request when installing the new version. (#46956, jmr in 19c9339)

• Added new variables macos_version and macos_version_major, which
  contain the full macOS version (like 10.15.7) and the major macOS
  version (like 10.15 or 11), respectively. The macosx_version
  variable is still available but deprecated.
  (#56252, jmr in 1916d6f)

• reclaim: remove everything under build and ccache directories.
  (#60126, khindenburg in b9fdb84, d08d261)

• For various actions, abort if @version specified is not current.
  (#60454, khindenburg, jmr in 835a7db, ca07195)

• Abort when a port includes a nonexistent PortGroup.
  (#59787, khindenburg in d913932)

• Adjust lint --nitpick on patchfiles to allow *.diff or *.patch.
  (#59695, khindenburg in 5037999)

• Display a progress bar when the underlying build system provides the
  necessary information, which is currently cmake and ninja.
  (#15939, landonf in da3524e)

• Support compressed web pages for livecheck.
  (#55011, dgilman in 8c41ca7, d741f0c)

• Added configure.sysroot variable, which is set to either
  ${configure.sdkroot} if an SDK is being used, or / if not.
  (#59798, jmr in 8d76ba6)

MacPorts 2.6.4

Changes since 2.6.3:

• Fixed incorrectly requiring a full Xcode installation when
  building all ports on Big Sur. (#61435, jmr in d58b124)

• Allow building ports for x86_64 on arm64 systems if they don't
  support arm64. (#61430, jmr in 94f428e)

• Disabled building the MacPorts SQLite extension by default, since
  the system's SQLite on Big Sur no longer supports extensions. Use
  the new macports.sqlext port, which has a dependency on MacPorts'
  sqlite3 port, to install it. (toby in 4664a4a)

• Fixed calculation of dependencies of up-to-date ports during
  upgrade when different variants are specified but
  --enforce-variants is not used. (jmr in 81979e5)

• Rev-upgrade no longer warns about libraries that are present only
  in the shared cache, since this is normal as of Big Sur.
  (jeremyhu in 601864d)

• Fixed incorrect output of 'port info --depends' when used with
  multiple ports. (#61083, ryandesign in a7cf423)

• Fixed incorrect warning that the SDK for the current OS version
  is missing, when configure.sdk_version has been cleared by the
  Portfile. (jmr in 8402cf8)

• Fixed some operations involving fs-traverse failing with paths
  containing whitespace. (ryandesign in 52609c9)

• Various changes to support arm64.
  (ryandesign, toby in c8ddc79, bfc0544, 7ccf5a2)

• No longer error out immediately when an appropriate SDK cannot
  be found, which prevented even actions like 'port info' from
  working in that situation. (jmr in 5764fd9)

MacPorts 2.6.3

Changes since 2.6.2:

• Correct macports-clang c++11+ compiler selection with non-libc++
  installations. (kencu in 3ea1fb4)

• Avoid problems with trace mode on modern macOS.
  (#60702, saagarjha, cal in d96e5a8)

• Added some basic support for Apple Silicon.
  (jeremyhu, jmr in 6eaa8d5, 901eb21, 01afdbb)

• Fixed an issue where post-extract ran with elevated privileges when
  adduser was used in a Portfile. (#50918, cal in ac1a9b0)

• Fixed cases where a proper error message was not displayed when curl
  failed. (#60581, cal in f535c26)

• Reduced the number of processes spawned when pinging mirror sites.
  (ryandesign in cee74bb)

• Support new naming scheme used starting with macports-clang-10 in
  configure.compiler. (jonesc in 5c3f571)

• Fixed dmg and mdmg targets on 10.15+. (#59697, jmr in 0459cb1)

• Ensure archive paths are correctly quoted when extracting.
  (#60365, jmr in 8a088c3)

MacPorts 2.6.2

Changes since 2.6.1:

• Added support for zsh to the pkg installer's PATH setup code.
  (cal in f9a3b2d)

• Allow individual ports to change prefix without disabling binary
  distribution for them. (jmr in d840f25)

• Added warning to install the Command Line Tools when using
  Xcode 10 or later and headers corresponding to the current OS
  version are not available. (jmr in 8a7d604)

• Always try macports-gcc on ppc systems if system compilers are
  blacklisted. (jmr in 42b36f4)

MacPorts 2.6.1

Changes since 2.6.0:

• Fixed error on older OS versions that use apple-gcc-4.2.
  (#59089, jmr in a3a71b5)

• Fixed 'port diagnose' check for command line tools on some older
  OS versions. (kencu in c2a1872)

• Silenced some SDK-related warnings that were repeatedly printed
  when using Xcode 11. (jmr in 73ee4b4)

• Improved performance with Xcode 11. (jmr in 3768efd)

• Fixed C++ compiler selection with Xcode 4.x on Snow Leopard.
  (kencu in 37c7cfe)

• Fixed 'port info --depends' printing the wrong set of fields.
  (#59149, jmr in e62716c)

MacPorts 2.6.0

Changes since 2.5.4:

• The default cxx_stdlib for 10.6-10.8 is now libc++. It is
  recommended that users on these OS versions run rev-upgrade to
  rebuild any ports using libstdc++. (jmr in 6b7846a)

• Extend the touch command to take a -W directory parameter.
  (#53730, khindenburg in a90c4b2)

• Added fetch.user_agent option to allow working around servers
  that don't like our default User-Agent string.
  (slewsys in e5a420c)

• Enabled sending custom headers in livecheck. (jonesc in 84f97ca)

• Improved explanatory message when a port cannot be built with
  +universal on macOS 10.14. (#57245, jmr in 918c347)

• Overhauled compiler selection logic. Ports can now specify that
  they require a particular C or C++ standard (e.g. C++11),
  Fortran, OpenMP, MPI, or TLS, and a suitable compiler will be
  chosen based on all these criteria. (mcalhoun in 5e17a69)

• Rewrote handling of *.env options. This should fix cases where
  environment variables were not being set because the old code
  silently failed to parse something and skipped all remaining
  variables in the list. This change requires different quoting in
  some cases: each list element now needs to contain a single
  assignment (like VAR=value). (jmr in 9313be5)

• 'port info' with multiple field options now outputs the fields
  in the order they were given. (#57003, khindenburg in e115b59)

• Added 'bump' action to assist in updating ports to new upstream
  versions. (satraul in 9c91a29)

• Added use_xcode option which indicates that a port requires a
  full Xcode installation to build (as opposed to just the Command
  Line Tools). This should allow MacPorts to only complain about
  Xcode not being installed when it's really needed.
  (#58016, satraul in 057ce2b)

• Allow using the 'macosx' SDK when the SDK for the current OS
  version is not present. This comes with its own problems, but
  it's better than not being able to build anything.
  (#57143, jmr in 8caac19)

MacPorts 2.6.0-rc1

Changes since beta1:

• Fixed port deps not showing depends_patch
• Added bump action to port man page
