Version 2.4.3 has just been uploaded. This version fixes a couple of bugs that were sure to come up, and also adds a bit more support in the way of Oracle and Subversion.
Specifically, the svnkit library has been upgraded from 1.1.4 to 1.2.1.5297 which adds support for Subversion 1.5 repositories. Also, Steve Bryant's DataMgr, which is used for the new automated installation script, has been upgraded to 2.2 beta which adds support for Oracle as well as Derby.
The new Backup/Restore feature was using some CF8 specific features but is not any more. It should now be more compatible with earlier versions of CF.
