Important fixes:
Downgraded H2 driver: 1.4.200 -> 1.4.197

(This doesn't affect MySQL users) The latest H2 driver isn't reverse compatible and doesn't automatically upgrade older databases, which results in a "Unsupported type 17" error.

Fixes:
Fixed a CancellationException error which could happen on reload or on shutdown.

2.4.3:

Fixes:
The "prevent_bypass" option will no longer prevent muted players from using non-blacklisted commands containing ":". Only blacklisted commands will be blocked, regardless of which plugin provides the commands.
(If /apples is blocked, then /fruit:apples will also be blocked, along with non-existent commands like /minecraft:apples or /bukkit:apples, but "/essentials:afk" will work fine)
Previously it would block every single command that contained ":", which caused trouble for a few plugins that run commands automatically through menus or clickable text.

2.4.4:

Minor fixes:
Fixed version number inconsistency issue from 2.4.3 (For some reason, the auto-generated bungee.yml had version 2.4.2, although plugin.yml, which was also auto-generated by the same tool, had version 2.4.3).
