Fixes come out when a new release is made.  Such a fix would rarely be rolled
into an existing release, and then only if it was desparately needed and the fix
was recent (ie. a bungled release).  To use a fix earlier, either use REL_ENG_2
(as it is updated periodically) or find the appropriate patches and apply them to
2.0.11.  Personally, I work with REL_ENG_2, but this may not be a practice you
(or your company) are confortable with.  Since REL_ENG_2 is changing, you must be
careful to test to make sure it is suitable for your needs.
