Released version 1.6 with many requested features, will be available for download today as soon as Bukkit staff validates it, see the changelog when available :
Such as :
Added : color codes support in lang.yml
Added: time limit (see config time-limit.enable AND time-limit.limit)
Added: deathmatch arena support (see config end-with-deathmatch , needs WorldEdit and arena.schematic)
Added : delay teleports of players at startup (delay each team by 25 ticks)
And many more ....
Developped against Spigot 1.8, but works perfectly for 1.8.3 too
I will make an official 1.8.3 version as soon as the option is available on dev.bukkit.org
There are still things on the todo list such as title,custom sounds, that are not in 1.6.
I didn't want to make you wait longer so you can enjoy the great new features right now. The other minor ones will come later.
