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.

News
====

 * GSettings fixes/improvements

   - GSettingsSchema API is now more powerful and consistent

   - new GSettingsSchemaKey API allows accessing metadata for keys:
     type, default value, range and the long-awaited support for summary
     and description

   - GSettingsSchemaSource gains support for listing schemas within a
     source.  Deprecate the global API that did this for the default
     source.

   - 'gsettings list-schemas' now works properly with --schemadir

   - deprecate a bunch of now-redundant functionality on GSettings

   - add API to GSettings for getting the default value of a key (as set
     by the sysadmin)

   - add API to GSettings for determining if the user has assigned a
     particular value to a key (ie: we are not just reading the default)

   - ignore qualified tags and attributes appearing in schema files

 * Applications/Actions

   - make GSimpleAction a bit more strict with respect to state changes
     that would violate the interface (ie: by changing the state type
     after construction)

   - throw an error when attempting to 'Describe' a non-existent action
     via D-Bus instead of returning a bogus description

   - throw an error when attempting to invoke unsupported methods on an
     Application (eg: 'Open' on an app that doesn't HANDLES_OPEN)
     instead of emitting a g_critical() in context of the app (which is
     not itself at fault for the errant call)

 * Appinfo

   - substantially rework GDesktopAppInfo to reduce the amount of disk
     accesses that are performed in common situations

   - add a new class: GAppInfoMonitor for discovering when applications
     are installed/removed

   - add a new g_desktop_app_info_search() API for searching for
     installed applications by name, keywords, etc.

 * GMarkup: add new G_MARKUP_IGNORE_QUALIFIED flag for skipping over
   "qualified" tags and attributes (those with a colon in the name, such
   as 'my:tag')

 * GDBus

   - ignore qualified tags, as above

   - GTestDBus: unset all D-Bus addresses (such as STARTER) to ensure
     that test programs don't pick them up

   - add new session_bus_run() convenience in the tests and use it

 * GRand: use real random data as a seed on win32 and use the
   timestamp/pid/uid fallback only on UNIX machines where we can't open
   '/dev/urandom'.  This may cause issues with older mingw32 releases
   due to a missing prototype for the rand_s() API.

 * Many win32 (and particularly MSVC) portability fixes.  Many
   additional tests are now runnable when building with MSVC.

 * Due to early testing of the (soon to land) GCleanup framework, a very
   large number of memory errors have been found and fixed (mostly in
   the testcases, but some in glib itself).

 * GIO:

   - some more seeking cleanups: particularly on GLocalFileInputStream

   - don't leave a .trashinfo file around if trashing a file fails

   - Add a request_certificate virtual method to GTlsInteraction
