I've packaged up the current state of the stable branch from CVS and put out a new release. There are a number of fixes and changes from the 20030829 release, so please do read the release notes!
Release notes and download: https://sourceforge.net/project/shownotes.php?release_id=196082
Updating should be fairly straightforward: if you used the install.php script, copy in your LocalSettings.php and AdminSettings.php and run update.php, otherwise copy things to the destination directory manually and run the SQL updaters noted in the release notes.
