Changelog: Velox v0.1.1 (1.21 – 26.3)

Maintenance release. Same physics, same supported versions, same settings. Needs Celeris 0.3.1.1 or newer.

Changes

• Java Kernel by Default: Velox no longer asks Celeris for its native kernel. In our CI tests the Java, JNI and FFM kernels give the same server tick, and the bit-for-bit check against the normal game passes with the Java kernel too. To use the native kernel anyway, add -Dvelox.nativeKernel=true to the server's Java arguments. -Dceleris.physics.engine=java still forces the Java kernel.
• Clearer Log: the startup line no longer suggests Java flags unless you asked for the native kernel.

Documentation

• Other Mods' Items: the notes now say what the code does. Only plain vanilla item entities are handled; items from mods that use their own entity class, a changed gravity or a ride are left to the normal game.
• Missing Celeris: the troubleshooting page now says NeoForge stops the server with a missing-dependency error, because Velox never starts without Celeris.
• Benchmarks: the README now shows the Minecraft 26.1 results next to 1.21.1 (about 12× falling and 9× resting) and says the tests use plain items on solid ground, so farms with hoppers or slabs gain less.
