Overview of changes in GLib 2.79.2, 2024-02-12

• More work to reduce lock contention and improve performance in GObject (#743,
  !3869, !3873, work by Thomas Haller)

• More API changes to libgirepository, which is now stable as of this release
  (#3155, #3217, #3218, #3231, #3234, #3243, #3244, #3245, #3246, work by
  Philip Chimento, Evan Welsh, Philip Withnall)

• Import g-ir-compiler, g-ir-generate and g-ir-inspect from
  gobject-introspection.git and update them to work with girepository-2.0,
  renaming them to gi-compile-repository, gi-decompile-typelib and
  gi-inspect-typelib (see docs/reference/girepository/migrating-gi.md) (!3853,
  !3909, work by Evan Welsh, Philip Withnall)

• Add new GLibUnix-2.0.gir, GLibWin32-2.0.gir, GioUnix-2.0.gir and
  GioWin32-2.0.gir GIRs which contain platform specific APIs, and are the
  preferred way for third parties to access those APIs in future; although
  platform specific APIs which were already exposed in GLib-2.0.gir and
  Gio-2.0.gir continue to be listed there; the underlying .so files have not
  changed (!3892, work by Philip Withnall)
