API cleanup - API is new and in new package org.screamingsandals.bedwars.api! You should update your addons to using new API because old API is not supported. And with this update API has same versioning as plugin. If you have old addons, you need to update it.
TeamColor refactoring - Since most players with better color perception didn't like old colors, we update it. Now you can't use old colors while creating new arena, but your arena configurations will be updated.
This update has new translation: Spanish (es), also now you can suggest new translations on crowdin: https://crowdin.com/project/screamingbedwars

Additions:

• Added /bw mainlobby command. If you set Main Lobby, all players will be teleported after game to this location.
• Added respawn cooldown - can be configured from the config file (respawn cooldown enabled, time and sounds)
• Improved upgrades format: https://github.com/ScreamingSandals/BedWars/wiki/Upgrades
• Added currency-changer shop variable (You can buy for example gold for 3 iron)
• You can join to full game as spectator. You need to allow it in your config.yml
• You can find new section in config: leaveshortcuts. You can set command shortcut for leaving the game.

Changes:

• WarpPowder is not working when you stay on your team spawn.
• Better Bungeecord support.
• TeamColor names was changed.
• API change versioning and package.
• You can now use & instead of § in language files.
• Team chests are now special items. So you don't need to use it. In configuration is variable turn-all-enderchests-to-teamchests if you set it to true, ender chests will be automatically marked as team chests, if you set to false and you want team chest, you need to set it as special item. The special item name is teamchest.
• Updated TeamSelector inventory, wools now shows player count with players in it.
• Now when you click on bed, you will see new block above it or next to it.
• Now there's folder languages and all custom language files should be here. All this files should have name language_<your language>.yml. If you have old language files, these files will be automatically moved and renamed.
• BedWars is now using our library for managing signs called SignManager. This information is not important to you at all.
• SimpleGuiFormat has more improvments, so in next versions default shop.yml will be updated, but you can use these new formats now.
• HolographicDisplays is not needed since this version.
• If you are using PaperMC (or PaperSpigot if you are using old versions), we will use faster way how to teleport you.
• You can now in your config.yml set breakable as blacklist instead of whitelist with variable breakable.asblacklist.
• Spawners can now be linked to teams. And of course the spawners can die with the team.
• You can set maxSpawnedResources for spawner. If the spawner reaches this value it will wait until the generated items are collected by player.
