If you want to follow SVN commits on some of my SVN repositories, you can subscribe to appropriate maling list, which gets notification on each SVN commit. I hope I set up mailman correctly and everything will work as I expect :-).
This list is also automatically forwared to packages.qa.debian.org, so you can also subscribe there for Debian package changes.
As phpMyAdmin themes for trunk are not compatible with 2.10.x releases, there was created 2.10 branch for themes compatible with those releases.
Today I added 2.10 themes to demo server and they are also available as subversion snapshots. I hope this will help fixing possible issues with them.
