Plugin has been rebranded to PreventStabby due to many name conflicts with other plugins.

It is recommended that you reset your config and database file before using new version, there have been few minor, but breaking changes.

Apart from that a lot of features have been added since last spigotmc release, here are hopefully all of them:

• Player mounts are now protected
• Added worldguard flag that forces players pvp on
• Fix a bug where plugin tried to check location of offline players for worldguard hook
• Fix concurrentModificationException when players happen to be removed from cache while combat check is happening
• Added convienience canDamage() methods to the api so you don't have to pass a boolean for displaying a message to the player
• Added initial PlaceholderAPI, not every message will parse placeholders as of now.
  
• API package changed names

You are now able to toggle if snowballs and eggs do knockback.

There are also events for combat enter and leave in the API.
