This is the second development release leading up to GLib 2.10.  


 * 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 2.8. If you have problems, you'll need
   to reinstall GLib 2.8.4.

 * GLib 2.10 will be source and binary compatible with
   the GLib 2.8.x series; however, the new API additions
   in GLib 2.9.1 are not yet finalized, so there may
   be incompatibities between this release and the final
   2.10 release.

 * Remaining issues for GLib 2.10 can be found with the 
   following bugzilla query:

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.
