+Clutter 1.23.6                                                       2015-08-21
+===============================================================================
+
+  • List of changes since Clutter 1.23.4
+
+    - Require Cogl 1.21.2
+
+    - Prefer the OpenGL 3.x Cogl driver
+    The GL3 driver drops legacy API, and should bring a slight performance
+    improvement, as well as lower memory overhead. If GL3 is not supported,
+    Clutter falls back to the older GL driver transparently.
+
+    - Updated translations
+   Catalan, Indonesian, Portuguese, Lithuanian, Spanish, French, Galician
+
+  • List of bugs fixed since Clutter 1.23.4
+
+    #742678 - gl: Prefer gl3 over the gl driver
+    #746279 - Typo (textues) in translatable string
+    #753895 - Incorrect plural form of child
+
+Many thanks to:
+
+  Adel Gadllah, Alexandre Franke, Anders Jonsson, Andika Triwidada,
+  Aurimas Černius, Carlos Garnacho, Daniel Mustieles, Fran Dieguez,
+  Jordi Mas, Pedro Albuquerque, Sebastian Rasmussen
