19.1.0-beta for Minecraft 1.21.1

What's Changed

This release optimizes channel computation. There is no network "booting" delay anymore: channels are recomputed and network devices become operational near-instantly. Released as a beta for now. Please let us know if you notice bugs in the new channel computation algorithm.
