This is the first development release leading up to GLib 2.22.


 * This is unstable development release. While it has had
  a bit of testing, there are certainly plenty of bugs
  remaining to be found. This release should not be used
  in production.

 * Installing this version will overwrite your existing
  copy of GLib 2.20. If you have problems, you'll need
  to reinstall GLib 2.20.

 * GLib 2.22 will be source and binary compatible with
  the GLib 2.20 series; however, the new API additions
  in GLib 2.21.0 are not yet finalized, so there may
  be incompatibilities between this release and the final
  2.22 release.

 * Bugs should be reported to

About GLib

GLib is the low-level core library that forms the basis for projects
such as GTK+ and GNOME. It provides data structure handling for C,
portability wrappers, and interfaces for such runtime functionality as
an event loop, threads, dynamic loading, and an object system.

More information about GLib is available at:

An installation guide for the GTK+ libraries, including GLib, can

Overview of Changes from GLib 2.20.x to GLib 2.21.0

* GIO:
 - New helper functions g_cancellable_connect/disconnect to avoid
   race conditions when connecting to the "cancelled" signal on
 - New types and methods for dealing with IPv4 and IPv6 addresses (and
   UNIX domain socket addresses under UNIX). This does not include code
   for actual socket I/O.
 - GResolver provides asynchronous and cancellable APIs for resolving
   hostnames, reverse lookup of IP addresses and resolving SRV records.

* Glib now provides hash and comparison functions for int64 and double
  types, suitable for use with GHashTable.

* GArray, GPtrArray and GByteArray can be ref counted now, and have
  boxed types.
