Bukkit

• The ability to choose a texture pack now requires the superperms (built-in Bukkit) permission "texturepackmenu.texture", which is granted by default. So, if you don't want certain players or groups to have the permission, you'll need to revoke/disable that permission.
• When new players first log in to the server, they will now get a notification that they can use the /texture command to choose a texture pack (but only if they have the permission to do so).

Requires Spout (see main page for details).
