A few minutes after Mojang issued the 1.4.6 update we also updated the Minecraft skyblock server.
You can update your client to 1.4.6 and login to play. The fireworks will be enabled this weekend during a server wide event along with Nether portals opening.
Murry christmas, ho ho ho
so why are fireworks disabled? DX
The will be enabled soon, hopefully by the end of this week.
