This version has automatic updates for your configs. If you don't want the plugin to update your existing configs, then add the following to your config.yml:
last-version: 1.5.6

Changelog:
* Added an updater for configs. This will add idiocracy and the jammer trap as well as make some changes to many other files. The files that come with the .zip archive are already updated to 1.5.6
* Added idiocracy, a gov type that determines that town owner by number of fireworks launched and number of signs placed with the player's name on it
* Added the jammer trap. This building will intercept teleporting players if they travel close to the trap. I'll create a video about this.
* NPC housing can now be upgraded. Buildings can now be rebuilt into one of several buildings (previously it was just one)
* The shelter will now set a respawn point when constructed (like sleeping in a bed). You can remove this by removing the bed effect from the shelter
* Added an option (enabled by default) to display town enter and exit messages as titles instead of chat
* Added an option to allow players to get money from killing a player even if that player had no money
* Added an option to disable teleporting in hostile towns
* Embassies can now be built in the settlement. Council room will no longer teleport allies.
* Fixed various bugs and improved the design of the conveyor and warehouse. Further improvements to conveyors might be coming, but this update looks pretty good
* Fixed a bug that allowed town members to break into town regions they didn't own using pistons
* Fixed a bug that had potion effects lasting longer than they should
* Fixed a bug that allowed players to use custom items to repair tools/armor at the smithy
* Fixed a bug that would prevent a town from being destroyed when the council room was destroyed
* Fixed a bug that prevented some MMOItems from being used as region inputs (Thanks @crston )
* The council room should not take more horizontal space when upgraded, but it will get taller.
* Fixed an NPE that could occur sometimes when a region evolves
