This update is a critical update for everyone using the plugin. If at all possible, please please switch to this update from the old version. Numerous bugs have been fixed and data storage has been overhauled entirely to prevent the data from being erased. However, You will lose your data (not config/milestones) upon updating.

New Features:
- Expanded the functionality of the API. Tutorial and documentation coming soon.
- Changed the way the plugin handles data. All data is now handled in - individual files rather than one large data file.
- Re-formatted commands to read /sl set [exp/level] instead of /sl addexp
- Changed /sl addexp to /sl set exp and gave it the ability to remove exp through negative numbers
- Added /sl set level command which allows you to set a player's level.
- Added an update checker which warns you in the console if your version is out of date

Bugfixes:

- Fixed a bug causing players to level too fast
- Fixed a bug causing all plugin data to be erased
- Fixed a bug causing the level up message to always display level 1 or 0
