The Meaning of Life, the Universe, and Everything.
I have the same issue also, Im the admin of a large MP server. Since the 1.4 update to clients today, Im confused to why the server files were not considered to be posted the same time??!?! Usually, its common practice to support the servers when clients are updated. Maybe not in MC.
On the off chance, I did update my bukkit and standard minecraft server installs but still are only workable for 1.3
There is a difference between server mods and the official server. Notch is not responsible for updating mods - 3rd party programs. You can simply run your server using the official server software until the admin of your mod updates.
