Changes since 2.11.4:

• Fixed unexpected behaviour of (x)install commands on APFS in
  some cases. (#72850, jmr in ea247a7, d8cfd53)

• Fixed a Makefile race condition that could cause installing
  MacPorts from source to fail sometimes (including when running
  selfupdate.) (#72802, jmr in 85db375)

• Fixed incorrect behaviour of portindex -p when not using an
  override file. (#72785, jmr in 1b58a9d)

• Fixed the last resort entry in release_version_urls used by
  selfupdate, which was pointing to the wrong branch and so would
  usually not indicate that a new version is available.
