This is the a development release leading up to GLib 2.24.

Notes:

 * 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 2.22. If you have problems, you'll need
  to reinstall GLib 2.22.

 * GLib 2.24 will be source and binary compatible with
  the GLib 2.22 series; however, the new API additions
  in GLib 2.23 are not yet finalized, so there may be
  incompatibilities between this release and the final
  2.24 release.

 * Bugs should be reported to http://bugzilla.gnome.org.


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:

 http://www.gtk.org/

An installation guide for the GTK+ libraries, including GLib, can
be found at:
