I've got a sprint scheduled now for PyCon 2009. I can only be there for the first day of sprints. If there's enough interest, we can probably find a way to sprint earlier during some of the open space session; or it can continue after I'm gone.
PyCon 2010 will be in Atlanta, GA, which is a lot closer to home, but not close enough that I can avoid lodging expenses.

Project Status: Community Participation Needed
John Eikenberry has taken over work on ZMySQLDA for some time now and has released ZMySQLDA 3.1. I don't have any ongoing Zope deployment except some Zenoss, and use MySQLdb directly, so I'm not a good test candidate. Superficially, there don't seem to be any outstanding issues.
Since Python 2.6 and 3.0 were released, there has been a lot of demand for prepackaged MySQLdb for those versions. MySQLdb-1.2.2 seems to throw some warnings on Python 2.6, due to a new Python set type (and the old Set module being deprecated), and some old-style exception usage. These problems should be fixed in the SVN version (MySQLdb-1.2 branch). MySQLdb was originally developed for Python 1.5 so some old crufty stuff is still hiding out in there. There are also some build fixes for Mac and Windows.
MySQL-1.2.3 is not too far off. There are probably a couple more fixes that need to go into the 1.2 branch. This will almost certainly be the last release in the 1.2 series. One outstanding question is what versions of Python should be supported in 1.2.3? I've settled on no longer supporting Python 2.3, but I won't go out of my way to break it yet (i.e. decorators, generator expressions). Python 2.4 seems reasonable to support. My current development platform (Ubuntu) has Python 2.5.2 so that's what I'm going to test against. I also plan to test against Python 2.6.
Python 3.0 is a different beast. I'm not sure if it will be possible to have a single version of MySQLdb that works on both Python 2.x and 3.x yet. I'm assuming not. I don't think I'll have Python 3.x support until Python 3.1 at least, though that seems to be not too far off. Guido van Rossum has indicated that Python 3.x will have a faster release cycle than Python 2.x; see PEP-3000. We might even see some early 3.1 releases by PyCon 2009.
MySQLdb-1.3, the precursor to 2.0 and the SVN trunk, is on hold for right now. Some of the fixes that are in the 1.2 branch need to be backported. Currently it does not do any type conversion; this has been removed from the C module and will be done in Python. I don't expect this to adversely affect performance. A lot more will be done using generators and more modern Python-isms. The question here is do I support Python 2.x or only Python 3.x. I'm inclined to say I'll develop it now for Python 3.x, and save backporting for later.
MySQL-5.1 was finally released. There are no big C API changes that I've seen (maybe no small ones either), so you should be able to build against it. For that matter, if you have MySQLdb built against the 5.0 client, I expect it to work fine with a 5.1 server, so save yourself some trouble and don't upgrade if you don't have to.
Similarly, if your OS vendor supplies packages for MySQLdb, use them. MySQLdb is known to be in a lot of Linux distributions, including Fedora, RHEL, Debian, Ubuntu, Gentoo, and others. It's also in the various *BSD distributions.
If you are running Windows or Mac OS X, I still don't use those platforms so I won't be building my own packages for them. If you want to contribute your own packages, I'll host them on SourceForge. Make sure you specify what version of Python and what version of MySQL it is built against.
I am planning a short sprint at PyCon 2009; it will not go any longer than Tuesday, unless there is a lot of unanticipated demand. In light of this, this is the approximate release schedule:
Late February 2009: MySQLdb-1.2.3 beta 1
Late March 2009: Sprint
Early April 2009: MySQLdb-1.2.3 release candidate 1
Mid-April 2009: MySQLdb-1.2.3 final
In order for a sprint to be effective, it can't be just me. I need people to help find, report, test, and fix bugs. I don't think we need more than two days to do this. I suspect we can get a lot done before the official sprint starts. We can probably make the trunk usable. If I could get one or two committed people at the sprint (not counting myself), I'd be happy.
Lastly, MySQLdb development is entirely funded by donations. Nobody pays me to work on it. I've been working on it for the past 10 years, 8 years on SourceForge. I have to plan development around my work schedule to avoid any conflict of interest or intellectual property issues. For the same reason, I am attending PyCon out of my own pocket. Donations are appreciated, though I could also use some interested developers. One or two have come forward lately; the important thing is that you submit patches through the bug/patch tracker. If your patches are good quality, I'll probably give you write access to SVN.
Feedback is solicited and welcomed.
