Most of you might have notice that the Spigot Team released the first DevBuilds for Minecraft 1.13, and I'm sorry to tell you that this will have a big impact on the UltimateFireworks Plugin.
Long story short: I'll split this plugin into two versions, one for 1.7 - 1.12 (This version will only get Bug-Fixing updates) and one for 1.13+ (With new content updates).
Why: Supporting 6 different minecraft versions is very difficult (Minecraft 1.7 has been released 5 years ago...) and with the new 1.13 version it got even more difficult.
But I'm sure that this will result into more frequently content updates.
