Overview of changes in GLib 2.83.0, 2024-11-06

• Update to Unicode 16.0.0; there may be bugs in linebreaking support, see #3518
  (#3460, work by Philip Withnall)

• Optimise UTF-8 validation of strings, including use of ifuncs to prevent
  spurious warnings from sanitizers and valgrind (#3481, work by Christian
  Hergert)

• Fix a potential buffer overflow in GSocks4aProxy (#3461, work by
  Michael Catanzaro)

• Change the default value of -Dglib_debug from auto to enabled for
  developers — distributions will almost certainly want to override it to
  -Dglib_debug=disabled for package release builds though; see #3421

• Revert per-instance locking changes in GCancellable as they introduced new
  races (#3448)

• Bump Meson dependency to 1.4.0 (!4244, work by Benjamin Gilbert)

• Rename multiple g_unix_mount_*() APIs to g_unix_mount_entry_*() (#3492,
  work by Jialu Zhou)

  work by Gleb Popov)

  (!3746, work by Evan Welsh)
