Afterburner

Afterburner 0.2.1 for NeoForge 26.3 (beta)

First build for NeoForge on Minecraft 26.3. Needs NeoForge 26.3.0.99 or newer. It carries the client and server optimizations of the Forge 26.3 build, including the dropped-item work from 0.2.1 and the settings screen.

New in this build, not yet in the other builds

• If another mod changes something an optimization hooks into, Afterburner tries to switch that optimization off for the run and name it in the log instead of crashing. Most cases are covered, not all: a few optimizations stop with a message naming the setting to turn off.
• Settings by dimension in config/afterburner-dimensions.properties, off by default.
• The new icon.

Left out for now (they rely on Forge-only code)

• Smaller chunks for Afterburner players (the chunk link).
• Skipping events no mod listens to.
• Forge's hopper-handler shortcuts, and the cheaper fluid pushing.

Tested

• A dedicated server and a singleplayer client on one laptop, on their own. Every mixin applies, terrain draws correctly and the settings screen opens. A hopper chain and a furnace gave the same results with Afterburner on and off.
• Not tested yet: large modpacks, or speed on NeoForge. The numbers on the project page were measured on Forge and Fabric.

Please report anything odd. This is a beta, so back up worlds you care about.
