Yesterday I'd tagged the much too late release 1.4.0. Late 'cause I had made more changes as I wanted while first planning.
Most important may that kdesvn now real knows about subversion 1.6 interface changes. Most of them aren't visible to user side. Second important: I'd integrated repository specific settings stored inside log cache database. This log cache may now viewed and deleted if not wanted, automatic log cache update may switched off per repository.
For more about this version read the Changelog.
Version 1.5.x is planned, but due some very important changes in my life it may delayed in time, too.
