Changelog

26.2.0

Rebuilt the whole thing from scratch. Decompiled the old jar, fixed a bunch of bugs, and turned it into a proper multi-platform project. Now works from 1.20.1 all the way up to 26.2.

New stuff

• Works on 1.20.1 through 26.2+
• Fabric version (finally). Two jars because Mojang removed obfuscation in 26.1, so old and new versions can't share one:
  • SmartOptimizer-Fabric-26.2.0.jar for 26.1+
  • SmartOptimizer-Fabric-1.20.1-26.2.0.jar for 1.20.1–1.21.11
• Folia support (uses the region scheduler when it detects Folia, falls back to the normal Bukkit scheduler otherwise)
• Tab completion on the commands
• Config gets validated on load now — if you put something dumb in there it clamps it to a sane value instead of breaking
• TPS fallback for Spigot (uses Paper's TPS API when it's there, reads tick times when it isn't)

Bug fixes (stuff that was broken in 26.1.2)

• Mob AI check was using distance() which does a square root every call — switched to distanceSquared(), way faster
• Chunk unloading straight up never worked for worlds that hadn't had a player in them yet. Dead code. Fixed
• Spawn chunk was being recalculated for every single chunk (O(n²) for no reason) — now it's once per pass
• Crashed if the command wasn't registered — added a null check
• Saving the config wiped out all your comments — doesn't anymore

Other

• Author is now endermanking_
• Paper jar is built against the 1.20.1 API targeting Java 17, so it runs everywhere from 1.20.1 to 26.2
• Fabric 26.2 jar: MC 26.2, loader 0.19.5, Fabric API 0.159.0+26.2, Java 25
• Fabric 1.20.1 jar: MC 1.20.1, yarn 1.20.1+build.10, loader 0.15.11, Fabric API 0.92.2+1.20.1, Java 17
