Please note: There is a scheduled 1.5.1 update in the very near future, to iron out some of the few remaining issues with 1.5, and it will be coming soon. Tomorrow's Snapshot will reveal more of what is to come, so keep an eye out!
You might be wondering where to start, or what sort of indescribably cool thing to create first. With so many new items, commands, and blocks, it's almost impossible to know where to start first! I don't have any good advice for that, except to show you something SethBling made with the 1.5 assets in the pre-release:
Rocket golem, or gassy golem - you decide!
The 1.5 release is a big one, and there is so much to do! What is your favorite part of the update? Tell us about it!
For those of you who read this before 10:00 EST, sorry about the early alert. This was scheduled to hit the front page the instant 1.5 was live. Unfortunately, I have no way to separate a scheduled post from the News section of the forum, so it shows up here regardless.
