Release 3.3.4 was published on 12.10.2020. It brings couple of small improvements and bug fixes.
Important note for H2 DB users: we have found a problem introduced in the release 3.3.0 related to the upgraded H2 DB 1.4.200. It is not working in a stable way under a heavy load. In this revision we downgraded H2 to 1.4.199. Up to our tests this should not cause any issues, but making a text backup is strongly advised.
