VersionPress 3.0.1 is a relatively small bugfix and reliability release and you can get it from GitHub now. It fixes 9 issues in total, 6 bugs and 3 other improvements.
If you're upgrading from VersionPress 3.0, you can use the new wp vp update
command that was shipped in 3.0 (see #906). Just download the ZIP file and run:
wp vp update /path/to/versionpress-3.0.1.zip
This will keep IDs from previous VersionPress installation which is more convenient than doing a full deactivation and reactivation.
Enjoy!
