Is there a way for my server to constantly check plugins for new permissions? Such as, lately, there came several new bukkit permissions, like the bukkit.command.timings? Like a plugin? Or a strange type of modification? Thanks.. :3
bukkit.command.timings is not at all new. You can see all the permissions needed on the Bukkit wiki (wiki.bukkit.org).
Detect? No. You have to read the changelog for plugins. CraftBukkit commands do not change very often, the last one being the timings command.
