+Overview of changes from GLib 2.29/2.30 to 2.31.0
+=================================================
+
+This release contains a huge number of changes (500 commits worth).  The
+list below attempts to summarise, but not every change is listed.
+
+* Major changes to threading and synchronisation
+ - threading is now always enabled in GLib
+ - support for custom thread implementations (including our own internal
+   support for errorcheck mutexes) has been removed
+ - a whole lot of dead code (to deal with the non-threaded case) has
+   been ripped out.  This includes the racy path of GMainContext that
+   caused deadlocks with respect to child process exits in
+   single-threaded programs (such as gtester).
+ - libgthread is now an empty shell and g_thread_init() is no longer
+   required (and has been deprecated)
+ - GMutex and GCond can now be statically allocated without explicit
+   initialisation.  Dynamic allocation for these types is deprecated.
+ - new types GRecMutex and GRWLock can also be statically allocated
+   without explicit initialisation.
+ - GPrivate can now be statically allocated and has an improved API.
+   Dynamic allocation of GPrivate is deprecated.
+ - GStaticMutex, GStaticRecMutex, GStaticRwLock, GStaticPrivate are
+   deprecated.
+ - GCond now uses monotonic time internally and a new API takes
+   monotonic time for timed waits, deprecating the wallclock API
+ - removal of the insane macro indirection used in the previous
+   implementation of threading and synchronisation APIs
+ - use SRWLock and CONDITION_VARIABLE APIs when available on Windows
+   (Vista and later) and emulate them on XP
+ - leaks of G(Static)Private-allocated data on some cases of thread exit
+   have been fixed
+ - simplified new thread creation API with the old API deprecated.  The
+   concept of joinability has disappeared (all threads are joinable) as
+   have priority levels, 'bound'ness (ie: kernel vs. userspace threads)
+   and ability to manipulate the stack size.
+ - GThread is now a refcounted type
+ - other implementation details changed
+
+* Move headers for some deprecated functionality to a separate
+  deprecated/ directory.
+
+* New support for attribute-based deprecations to issue compiler
+  warnings instead of breaking the build and/or giving warnings about
+  implicit declarations (and possibly miscompiling).
+
+* GCache has been deprecated (after its last use was removed from our
+  platform over a year ago).
+
+* It is no longer possible to include individual headers (like
+  "ghash.h") -- you must #include <glib.h>.
+
+* The misguided experiment of allowing the program to stumble along with
+  missing GSettings schemas is now over -- the abort is back.
+
+* Clarify that fork() is not valid while using GMainContext.  This is
+  because the internal resources of the GMainContext end up being shared
+  by both processes.  We had an assert here but it was breaking existing
+  (valid) use cases as well, so it has been removed for now.
+
+* GApplication
+  - add ::shutdown signal as logical dual to ::startup
+  - don't use a GMainLoop: iterate the GMainContext directly (improves
+    quit logic)
+
+* Several portability fixes for Windows, OpenBSD, Solaris
+
+* Add new GValue API to specifically deal in signed chars (in case the
+  platform defines 'char' as unsigned)
+
+* Use CLOCK_MONOTONIC unconditionally if the libc has support at compile
+  time (ie: stop checking for kernel support at runtime).
+
+* SOCKS proxy and resolver improvements
+
+* Fix the spelling of G_IO_FLAG_IS_WRITABLE (was WRITEABLE) and
+  introduce a macro for backwards compatibility.
+
+* GDBus: many code generation updates and improvements
+
+* GVariant:
+  - new g_variant_new_from_fixed_array() API
+  - substantial docs improvements/clarifications
+
+* mount monitoring is now based on /proc/mounts (where available)
+  instead of mtab
+
+* new macros G_SOURCE_CONTINUE and G_SOURCE_REMOVE for returning from
+  GSourceFunc (so you don't have to remember what TRUE and FALSE mean)
+
+* use xlocale functions where available to avoid too much heavy lifting
+  in functions like g_ascii_strtod()
+
+* GMappedFile can now be created from an fd
+
+* error message strings grammar/i18n fixes
+
+* many docs updates
+
