Overview of changes in GLib 2.73.3, 05-08-2022

• Revitalize G_REGEX_OPTIMIZE flag and use it to enable PCRE JIT compiler (work
  by Aleksei Rybalkin) (!2817)

• Fix some regressions due to the PCRE2 port (work
  by Aleksei Rybalkin, Mamoru TASAKA and Marco Trevisan) (!2814, !2827, #2694,
  #2699, #2700)

• Fix a pidfd leak that was introduced in the previous release (work by
  Christian Hergert) (#2708)

• Support compilation without a C++ toolchain (work by James Hilliard) (!2822)

• GDBus: Use namespace-friendly protocol for Linux message buses, and optionally
  other connections (work by Simon McVittie) (!2832)

• Fix potential races in multi-threaded signal connections handling (work by
  Marco Trevisan) (!2823)

• Add back gio-launch-desktop to redirect stdout/stderr of launched
  GDesktopAppInfo's to the journal with proper parent (work by Simon McVittie)
  (!2818, !2819, #2682)

• Executables that are invoked when installing other software, typically
  from packaging system triggers, can now be installed into
  architecture-dependent locations. Unix OS distributors who install
  GLib for more than one architecture in parallel (multiarch or multilib
  installations) should consider building with -Dmultiarch=true, installing
  the bin/glib-compile-schemas and bin/gio-querymodules symbolic links in
  packages for the primary architecture, and omitting those symlinks from
  packages for secondary architectures. (work by Simon McVittie) (!2818)

• Some enumerators introduced in previous releases have been changed, for better
  introspection results:

  • G_MARKUP_PARSE_FLAGS_NONE renamed to G_MARKUP_DEFAULT_FLAGS
    
  • G_TLS_CERTIFICATE_FLAGS_NONE renamed to G_TLS_CERTIFICATE_NO_FLAGS
    
  • G_APPLICATION_FLAGS_NONE was deprecated, use G_APPLICATION_DEFAULT_FLAGS now
    (work by Emmanuele Bassi) (!2835)
    

• gfileinfo: Implement xattr attribute removal (work by madmurphy) (#1187)

• Add support to --delete option to gio set, to unset a file attribute (work by
  codeboybebop) (#2588)

• Improve default value of glib_debug option: G_ENABLE_DEBUG will be defined
  only if using --buildtype=debug or enabled via -Dglib_debug, but it
  won't ever be set if an optimized build is requested (specifically if the
  optimization level is not 0 or g) as it may be the case when using
  --buildtype=debugoptimized (work by Michael Catanzaro) (!2851)

• Probably the first revision of any GNOME module ever released from Cuba :)
