Phonon

0.4.0-beta.1

For Minecraft 26.2, up from 0.3.1.

Changes

• Phonon runs on Fabric as well as NeoForge, with the same blocks, items, commands and settings. It needs Fabric API. Settings are in config/phonon-server.json and config/phonon-client.json, and Mod Menu shows a button for the client settings.
• A Fabric client whose Phonon can't talk to the server's is told to install the server's version when it joins, as NeoForge already does.

Fabric and NeoForge players can't join each other's servers, since the loaders differ. On NeoForge nothing changes for players.

Test evidence

• Targets: Minecraft 26.2 with NeoForge 26.2.0.93, and with Fabric Loader 0.20.1 and Fabric API 0.161.0+26.2. Java 25, tested on macOS on Apple Silicon.
• 63 automated tests pass.
• The scripted checklist passes on both loaders in the real client and on a dedicated server: playback controls, several speakers, stations and the boombox, 1 MB cache eviction, resource reload, reconnecting and a server restart.
• Two clients on a dedicated server stayed in sync. Fabric: -20 ms at late join and -2 ms after a seek. NeoForge: -30 ms and -20 ms.
• Production dedicated servers for both loaders, set up by NeoForge's installer and Fabric's server launcher, start with the release jar, run /phonon reload and stop cleanly.
