Back in the day when I updated Wurst to Minecraft 1.8, I made a pre-release as soon as I got a somewhat working version and then kept making more pre-releases until it was stable. The update to Minecraft 1.9 will work the same way.
Working features:
- Most commands
- FastPlace
- Flight
- All Killauras & TriggerBot
- Movement hacks (Spider, Glide, etc.)
- ServerFinder
Broken features:
- AutoArmor
- AutoSoup
- AutoSplashPot, .potion, etc.
- AutoBuild, BuildRandom, etc.
- BowAimbot & Trajectories
- All ESPs
Everything not listed above is untested and could be either working or broken. The auto-updater should be working, but I cannot guarantee it.
If you get a crash:
Delete modules.json in your Wurst folder (default location: %appdata%\.minecraft\wurst).
