+ New packet library PacketEvents. This is a hard dependency!
+ Workaround for console logger, you can now see all log messages in the console once again
+ CommandHider to hide the presence of ACA without permissions
+ InformationHider that bundles the previous EnchantmentHider with the new ItemCountHider
+ ItemCountHider obfuscates the item counts of held items
+ Inventory Frequency part to detect constantly opening and closing inventories in an attempt to bypass detection
+ WorldGuard hook for teaming check
+ Scaffold Face check to fix some bypasses
* Improved Scaffold Rotation with a new check for rotation flips
* Sometimes, commands were not correctly loaded from the config
* Fixed the significant rotation part of Scaffold Rotation having way too high thresholds
* Scaffold Rotation variance is now more effective at detecting cheats
* Rebalanced Scaffold rotation for fewer false positives
* Skinblinker is again available on all versions
* Drastically improved performance for various packet checks thanks to PacketEvents
* The permissions and internal module_ids (the latter being only relevant for developers using the API) no longer include the "anticheataddition_" prefix
* Using the ACA command no longer requires the anticheataddition.null permission, it now has the dedicated anticheataddition.maincommand permission
* Updated the information inside plugin.yml
