Bukkit

 - 0.9
   - Updated to use the latest RB of bukkit (1.2.5-R4)
   - Uses the new version of the SQL library which keeps the connection open for the entire time the plugin is enabled thus reducing the number of connections made to the SQL server.
 
 - 0.8beta3
   - Definitely fixes the SQL query error
   - Improves the addition of extra columns
   - No longer errors out if it tries to add a new column that already exists
   - Minor improvements in the SQL code

 - 0.8beta2
  - Fixes error in SQL query

 - 0.8beta1
  - Players are no longer removed from the database, they are instead flagged as online or offline (field in the table is called 'online', 1 = on, 0 = off).
  - a bit more restructuring of code

 - 0.7
  - New In-game command (/onl resync), currently can be used by anybody, didn't really see a reason to restrict it since it isn't all that harmful.
  - /onl resync - will resync all currently logged on players.

 - 0.6
  - You can now choose the name of the table by editing the config.yml files 'MySQLTable' value.
  - Now depends on the 'vault' plugin also being installed in order to deal with permission groups
  - If vault returns the permissions plugin you are using, the SQL tables 'permission_group' field for a player will now store what primary permission group they are in.
  - You can now turn debug info on and off by changing the config.yml files 'showDebug' value from 'false' to 'true' and vice-versa. debug info is nothing more than just showing some info on the console window such as 'player join' 'permission group', etc...

 - 0.5
  - Cleaning up of old code from when i first created it
  - Structuring the SQL side of the code a lot more
  - Storing all the SQL settings in a config.yml file
  - Renaming of old plugin 'OnlinePlayers' to 'OnlinePlayersSQL' to remove confusion about the storage mechanism used by the plugin.

 - 0.1 - 0.4
  - Changelog was never really tracked because it was only used on our server.

Beta, may not be stable, use at own will.
