This version of the plugin is not stable! And the update has been added only in paper mode; it will be available soon for Spigot as well! There are many breaking changes, so I would not recommend using this build.
Added Dynamic Mob System
Changes on the default avamposts.yml file
Added new parameters on default avampost type, cooldown
Removed boss section
Improved a lot the performance of the plugin
Added initial system of cooldown for each avampost
New type system (initial) for support new type of avamposts (for the moment only killmobs)
