(Lack of) server updates.
There have been two bugfix releases of Minecraft (1.12.1 and 1.12.2) since we last updated the creative server, but we've decided to wait to update our server version until the next point release (apparently they're skipping 1.13 and going straight to 1.14). ¯\_(ツ)_/¯
Similarly, since ComputerCraft has gone open source there have been some updates to it, but we're going to wait until we have adequate time to test them before we attempt to upgrade our ComputerCraft server.
The Minecraft U modpack on Technic was temporarily broken until today, however (I let a domain name expire...oops), so if you've had issues with it, try again.
All that to say, the current server instructions are still up to date!
