8.3.3 BETA b4

Most probably the last 8.3.3 pre-release before the 8.3.3 BETA is out of its beta stage. This code is as stable as it gets, even implementing some new features (about which you can learn here and here). It's been tested and scrutinized and feedbacked-upon by our community of server owners and testers, so if there is a bug, it would be a non-game-critical one or very much an edge case scenario somewhere. Feel free to install this one on your servers without the fear of data loss.
