+Release Notes for Clutter 1.10
+-------------------------------------------------------------------------------
+
+• Clutter can support multiple backends in the same shared library. Only one
+  windowing or input backend can be used at run time. As a result of this
+  change, the shared library name used by Clutter has changed from:
+
+        libclutter-<flavour>-<API version>.so
+
+  to:
+
+        libclutter-<API version>.so
+
+  The pkg-config file has been updated accordingly. Until the next major API
+  break, Clutter will ship compatibility links for all the previous "flavours"
+  that were available in versions < 1.10; this allows applications dynamically
+  linking against Clutter, or using dlopen(), to keep working. For libraries
+  and applications dynamically linking against Clutter, though, it is still
+  recommended to recompile to make sure that the most recent version is being
+  used. Language bindings using GObject Introspection will automatically use
+  the new shared library without requiring any change.
+
+• The windowing system backend for the CE3100 and CE4100 platforms using the
+  libgdl library is now implemented as a separate backend instance, instead
+  of being a sub-flavour of the EGL native framebuffer backend. This change
+  introduces a new header file, under $includedir/clutter-1.0/clutter/cex100,
+  which should be included to access the CEx100-specific API. The API and
+  ABI of the platform API has not been changed, though it should still be
+  considered experimental.
+
+• As of 1.10 it is not necessary any more to call clutter_threads_init() to
+  initialize threading support in Clutter; after the changes in GLib 2.32,
+  threading support in Clutter is always enabled. The rules on how to use
+  Clutter from multiple threads haven't changed.
+
+• Deprecated API is now marked using the CLUTTER_DEPRECATED and the
+  CLUTTER_DEPRECATED_FOR annotations; these two annotations will result in
+  compiler warnings when attempting to use the deprecated API. It is possible
+  to disable deprecation warnings for Clutter by defining the
+  CLUTTER_DISABLE_DEPRECATION_WARNINGS symbol when compiling. The previous
+  deprecation symbol, CLUTTER_DISABLE_DEPRECATED, is only used for macros.
+
+• Deprecated functionality has been moved to separate header files, installed
+  under the $includedir/clutter-1.0/clutter/deprecated directory. These files
+  are still included by default by clutter/clutter.h.
