This is the legacy (1.x) version of MySQLdb. While it is still being maintained, there will not be a lot of new feature development.
This is the old Subversion repository located on SourceForge. It has all the early historical development of MySQLdb through 1.2.3, and also is the working repository for ZMySQLDA. The trunk on this repository was forked to create the MySQLdb2 repository.
This is the new (active) git repository. Only updates to the 1.x series will happen here.
This is the now obsolete Mercurial repository for MySQLdb-2.0 located on SourceForge. This repository has been migrated to the moist repository.
