Bukkit

v5.9
- Added ability to set levels for blocks even if the block is not part of the actual skill. This allows for denying of mining blocks until you reach a certain level.

v5.8
- Added itemData support. Use it like this: 'itemId:itemData'. Orange wool, for example, would be '35:1'. You can use this with levels and XP.
- Some general fixes
- You can now find the Skills plugin along with sources and javadocs at my nexus at http://centrility.nl:8081/nexus/ (This is a Maven repository)
- Although it's not default in the config, Farming should "work" now.

v5.7
- Added color support for all messages.
- Some general cleanup

v5.6
- Fixed some API stuff
- You can now change the skill name. To do this, add the skills.<skillname>.name variable in skills.yml
- Avoid player data being reset by not creating a variable on checking
- Fix issues with Citizens 2
- Check WorldGuard before adding XP for EntityDamage, Death, BlockBreak and BlockPlace.
- Using a new Updater, made by H31IX which uses BukkitDev for checking and downloading
