IMPORTANT: Read this if you play Minecraft on Tertius
The 1.5 update is due out this week.
IF YOU UPDATE YOUR CLIENT WHEN IT IS RELEASED, you will not be able to get on the server for a few days. This is because Tertius uses a modded version of the MC server called Bukkit. Bukkit will not be compatible with the official update for a few days, until the modding community catches up with changes in the code. The last time an official patch came out, they had fixed everything within about 48 hours.
Luckily, Minecraft does not force you to install new updates anymore. If you are using the latest client from Minecraft.net, you are seeing a "Minecraft News" launch screen. This screen will give you the option to update or not update when a new patch is released. If you do not see the "Minecraft News" screen at launch, download the client again (it's like a half a megabyte, folks).
To continue using the server when 1.5 is released, choose DO NOT UPDATE.
When the coast is clear, I'll let everyone know and we can update to the new goodies. These include rain, lightning, and snow storms, powered tracks, and more.
