Hot bugfix was issued, which covers slight inconsistency with kicking players that are not whitelisted. This prerelease addresses an issue where players can for a very brief moment join the whitelisted server before being kicked. That causes their in-game profile being created and join/leave message to appear for all players. That issue can clog the server file system with inactive player data and some other plugins can work with these data as well, which for example may bias your server stats.
