WebGUI

[1.4.1] — 2026-06-11

Fixed

• NeoForge: clients could not join a dedicated server (#4). The server-to-client payload channels (open_web, main_menu, emit, entity_context) were registered only on the physical client, so a dedicated NeoForge server never declared them. Joining clients were rejected during channel negotiation with Channel [webgui:open_web] failed to connect: Client wants payload to be sent in: CLIENTBOUND, but server doesn't support it!. The S2C payloads are now registered in common init on both sides; the receive handlers still run client-side only.

[1.4.0] — 2026-06-11

Added

NeoForge support

The mod is now multi-loader. The codebase is split across loaders with Stonecutter, so the same source builds for both Fabric and NeoForge.

Minecraft	Fabric	NeoForge
1.20.1	✅	— (NeoForge moddev 2.x targets 1.20.4+)
1.21.1	✅	✅
1.21.11	✅	✅

• NeoForge builds use Mojang mappings; Fabric builds use Yarn — handled automatically at build time
• All existing features (entity binding, events, signed tokens, HUD overlays, commands) work identically on both loaders
• WebviewApi and the window.webgui browser surface are unchanged — no migration needed for existing web UIs
