* Bug fixed: Drizzled could crash when filesystem permissions cause writing a pid file to fail. (Brian Aker)
* Bug fixed: An undocumented ipv6_function was enabled and could crash drizzled if called - the function was disabled. (Fixed by Henrik Ingo.)
* Bug fixed: In master master setup, slave plugin would try to apply transactions originating from itself. (Joe Daly)
* Bug fixed: Fix performance regression introduced with catalog being added to key. (Brian Aker)
* Bug fixed: actually return the next exception in Exception::getNextException() & Fix for execute parser to recognize escaped semicolons. (David Shrewsbury)
* Bug fixed: A typo in assertion causing false positive failure with log > 4GB.
* Updated docs. Check out comprehensive replication documentation! (Daniel Nichter, Henrik Ingo, Muhammad Umair, Brian Aker, et.al.)
* Cleanups to drizzle and drizzled --help output and error messages. Standardize plugin names. (Daniel Nichter, Mohit Srivastava)

Known issues

All of the optional plugins are packaged in their own package. These are named drizzle-plugin-*. If a plugin is installed, it is also configured to load by default. (see /etc/drizzle/conf.d/pluginname.cnf) However, not all plugins actually work without further configuration. These plugins will cause the server startup to fail. The workaround is to either configure the plugin to work, or uninstall it if you don't want to use it. (Related blueprint) In short, you should only install the plugins you want to use. Don't install all available plugins.

Please post bugs on the Drizzle bug tracker and questions and general feedback to drizzle-discuss mailing list.
