The second pre-release of ReiserDriver is now available, with MANY bug fixes and improvements. It is available under the 'Releases' section as 'RFSD Pre-release v2.' (See the SourceForge release notes for full details.) The build is now feature complete.
This version should be relatively stable, and is in need of plenty of testing love! It is the last planned pre-release before the final release on August 9th.
