- Added ``Setuptools`` support to create an egg package thanks to
Brett Carter.

- Added condition to handle connection getting "out of sync". This can occur
when, for instance, you get a stray semicolon in a query. When a connection
gets in this state it is hosed and must be closed and reconnected.

- Made some changes to how ``use_unicode`` and ``auto_create_db`` are set to
better allow for subclassing and extensions of the base classes.

- Added handling of NEWDECIMAL which was added for mysql 5.0.

- Added basic support for procedure calls using ``CALL`` query.

--------
- Fixed issue with ``sql_quote__`` getting called prior to connection being made.

- Fixed bug 1916952. Updating to API change in MySQLdb 1.2.2 ping method.

- Fixed backwards compatibility issue with MySQLdb versions <= 1.2.1.

---------
- Fixed pernicious corner case bug with joining a transaction after the
transaction has started and been aborted.

- Zope dependency raised to Zope-2.8 or newer.

---------
- Unicode support now works!

- Unicode support reworked to use MySQLdb's unicode support instead of its
own half-baked layer.

- Minor cleanups and extensions to database introspection methods.

- Minor cleanups/fixes to dtml.

- Removed a few unnecessary thread locks.

- Changed failed query logging entries from errors to warnings.
