Version 4 Note - This starts some important internal changes. Compatibility with older database version is 100% and this is one of the targets. Version 3 was designed with a much older API version and a lot changed in last updates so a need to update the core code in favor of the new versions is needed. Older API versions will still work but the code will be improved to target latest versions and also keep compatibility even this is getting harder and harder. This 4 major update will be completed with few more updates on each sync module and after that I will focus on bugfixes.
Added support for Spigot 1.18 API
Changes to Inventory, Armor and Gamemode sync module (internal code).
