+glDeleteTextures(), glDeletePrograms() and glDeleteBuffers() Changed
+--------------------------------------------------------------------
+
+To match the behaviour of other OpenGL implementations, glDeleteTextures,
+glDeletePrograms and glDeleteBuffers have been modified so that:
+
+  * The named texture/program/buffer ID is immediately freed for re-use.
+
+  * The actual texture object, program or buffers isn't really deleted until
+    it is no longer bound in any rendering context (the reference count
+    is zero).
+
+Previously, the texture/program/buffer ID wasn't freed until the object
+was really deleted.
+
+Note that textures, programs and buffers can be shared by several rendering
+contexts so they can't be deleted until they're unbound in _all_ contexts.
