Changes

Added

  • NeoForge support. 13 NeoForge jars (mcpfabric-neoforge-<version>+<mc>.jar) for Minecraft 1.21.1, 1.21.3–1.21.11, 26.1.2, 26.2 and 26.3, with the same tools, bridge and config as the Fabric build, published to the same Modrinth project as their own releases. 1.21.2 is not covered (NeoForge only shipped two abandoned betas for it).
  • info.status now reports the mod loader ("loader": "fabric" / "neoforge").

Changed

  • Loader-specific code is isolated behind a small Platform layer and per-loader entrypoints (dev.mcpfabric.fabric, dev.mcpfabric.neoforge); everything else is shared. The Fabric entrypoints moved to dev.mcpfabric.fabric.FabricEntrypoint and dev.mcpfabric.client.fabric.FabricClientEntrypoint.
  • Fabric and NeoForge are released independently: a vX.Y.Z tag publishes only Fabric, a neoforge-vX.Y.Z tag only NeoForge (publishFabric / publishNeoForge, buildFabric / buildNeoForge). publishMods is gone.
  • NeoForge nodes build against binary-patched Minecraft (ModDevGradle disableRecompilation), which keeps the 13 extra nodes fast and light on memory in CI.

Fixed

  • Client RPCs sent while the game is still starting return no_client_player instead of an internal NullPointerException (on NeoForge the bridge starts before Minecraft exists).
