Overview of Changes from GLib 2.9.0 to GLib 2.9.1
=================================================

* Memory management
 - The slice allocator is implemented [Tim Janik]
 - g_slice_free_chain() has been renamed to 
   g_slice_free_chain_with_offset()  [Tim, Behdad Esfahbod]
 - Mem chunks are deprecated [Matthias Clasen]

* Data structures
 - Hash tables are refcounted, and have a boxed type [Tim]

* Thread support
 - Support for Solaris threads has been removed 
   [Sebastian Wilhelmi, Andrew Paprocki]
 - g_async_queue_sort(), g_async_queue_push_sorted() have 
   been added to allow GAsyncQueue to be used as a priority 
   queue, together with the corresponding _unlocked 
   variants  [Martyn Russell]

* GObject:
 - The concept of a floating initial reference has been
   moved from GtkObject to GObject [Tim]

* Win32 changes:
 - Make g_rename() replace existing files [Tor Lillqvist]

* Misc new API:
 - G_GUINT64_CONSTANT macro to define guint64 
   constants [Andrew Paprocki]
 - G_GNUC_WARN_UNUSED_RESULT macro to instruct the 
   compiler to emit a warning if the value returned
   by a function is ignored. [Arjan van de Ven, Alex Larsson]
 - GList and GSList now have sort functions which take an
   extra user data argument [Martyn Russell]
 - g_param_spec_ref_sink() has been added for consistency [Tim]

* $LOGNAME is respected when determining user data. [Laszlo Peter]

  Christian Persch, Benedikt Meurer, Andrew Paprocki, 
  Kazuki Iwamoto, Alexis S. L. Carvalho, Stanislav Brabec,
  Andreas Schwab, Kalle Vahlman]

* Documentation
 - Deprecation warnings carry version information [Matthias]
 - The slice allocator has been documented [Matthias, Tim]
 - Other improvements [Morten Welinder]

Overview of Changes from GLib 2.8.x to GLib 2.9.0
=================================================
* Unicode support:
 - The Unicode tables have been updated to Unicode 4.1, 
   adding several new values to the GUnicodeBreakType 
   enumeration. This breaks Pango <= 1.10 
   [Behdad Esfahbod]
 - The various Unicode character predicate functions 
   (g_unichar_isalpha, g_unichar_isdigit,...) have
   been optimized
   [Behdad]
 - g_utf8_pointer_to_offset, g_utf8_offset_to_pointer:
   These functions handle negative offsets now, and
   going backwards in g_utf8_offset_to_pointer uses
   "stutter stepping".
   [Larry Ewing, Matthias Clasen]

* Memory management:
 - Mem chunks are no longer used internally in GLib and
   GObject. GMemChunk will be deprecated in GLib 2.10
 - All APIs based on GAllocator (g_list_push/pop_allocator,
   and similar push/pop_allocator functions for other
   data structures) have been deprecated, since they
   never worked as intended.
 - The g_slice_* functions have been added as a 
   new API for fast allocation of small memory blocks. 
   The implementation in GLib 2.9.0 is just a simple 
   wrapper around malloc. GLib 2.10 will have an
   efficient and scalable implementation. 
   [Tim Janik, Matthias]

* Pattern matching:
 - g_pattern_match has been optimized to avoid
   unnecessary recursion.
   [Tim, Matthias]

* g_intern_string, g_intern_static_string: 
 - New functions to intern strings. These are now used 
   by GObject to avoid duplicating static strings 
   [Matthias]

* g_thread_foreach: 
 - New function to iterate over all GThreads 
   [Tim, Matthias]

* g_date_set_time_t, g_date_set_time_val:
 - New functions to set a GDate from a time_t or
   GTimeVal value. g_date_set_time has been deprecated 
   in favor of these.
   [Roger Leigh]

* g_snprintf and g_vsnprintf:
 - These functions are no longer declared in gprintf.h, 
   since they are in glib.h
   [Matthias]

  in GValues should also be changed to access 
  v_long, not v_int, in order to work on bigendian 
  64bit machines.)
