You can now set some more values in the config.
I also switched the update checker. I use my own update service now, since I dont want to depend on spigot and also want to allow automatic updates and not only checks. Read more below.

In General Settings:
updateReminder - This will remind you when a new update is available. This is checked only once on startup
autoUpdater - If you use the update reminder you can use the auto updater as well.
This Updater is pretty secure and wont break anything. It just downloads the new version from our servers, checks the hash of the file and saves is to your update folder. The hash will secure file integrity. Bukkit will install this update after a restart.
Trust me this one wont break anything. I use it by myself, because its a pain keeping all my testservers and servers updated...

In world settings:
alwaysManageCreepers - If the setting creeperBlockDamage is set to true the block damage is always canceled. If you want to enable this only during blood nights set this to false.

Also creeperBlockDamage and alwaysManageCreepers are now configurable via the manageworlds command.
