First off I would like to announce that until Craftbukkit, bukkit, and the mod communities come up with newer versions of the mods to support this latest update, we will be disabling all of our mods.
However, the good news is that the version 1.5 update has done some amazing things, my favorites being these two:
The random kicking from the server, and the server crashes, should stop altogether. If we have problems then it will most likely be userside or serverside.
Weather - The weather is amazing, the rain sounds cool both indoors and out, looks cool, does not spike fps, and the snow replaces snow blocks that have been broken and even spreads snow if the biome supports it.
If you would like to read more about the update, here is the official link:
Thanks again fellow Minecrafters.
