Intro:

Following our new releases of Forge recommended builds for the 1.21 family, today we release our very first recommended build for 1.21.1. Many, many changes have since been made to Forge since the initial release of Forge 52.0. If you're interested in catching up on some of the details of the bigger changes we've made over the past year, you should read my 2024 year-end forum post: Fresh from the Forge 2024.

1.21.1 is covered under active support.

New:

• Change tick event to have pre/post classes (#9890)
• Make ForgeSpawnEgg assume color is opaque if alpha is set to 0
  • Fixes "invisible" spawn eggs by default, but still allows modders to specify partial transparency.
• Add support for named sub-capabilities
• Make HangingSignBlockEntity useable with custom BlockEntityTypes (#10038)
• Use the new fire() and Result#isAllowed/isDenied/isDefault methods from EventBus (#10028)
• Bump Mixin to 0.8.7
• Patch CropBlock to use instanceOf FarmBlock check instead of hard coding to Blocks.FARMLAND (#10044)
• Add a way to render tooltips from Formatted text and TooltipComponents elements (#10056)
• Load mods that declare explicit 1.21 compatibility as 1.21.1 is a minor bugfix
• Add level access to Item.TooltipContext if available
• Mod loading cleanup and optimisations (#10052)
• Add a few Method Helpers onto ResourceKey to make getting Data Driven Entries Simpler (#10071)
• Fire `OnDatapackSyncEvent` when a player joins a server (#10076, #10171)
• Optionally supply FMLJavaModLoadingContext as a param to mod constructors (#10074)
  • Before:

    public MyMod() {
        // getting the mod bus - uses FMLJavaModLoadingContext
        var modBus = FMLJavaModLoadingContext.get().getModEventBus();
     
        // registering configs - uses ModLoadingContext
        ModLoadingContext.get().registerConfig(/* ... */);
        // ...
    }

  • After:

    public MyMod(FMLJavaModLoadingContext context) {
        // getting the mod bus
        var modBus = context.getModEventBus();
    
        // registering configs
        context.registerConfig(/* ... */);
        // ...
    }

• Add and fire SystemMessageReceivedEvent
  • Replaces ClientChatReceivedEvent.System which was not fired due to Mojang changing ChatType to a registry.
• Sync component registry ids
• Stacktraces now have the transformers displayed after itself, and not included with each element
• Implement the de-facto common tags, add many new Forge tags while retaining backwards compatibility (forum post, #9955, #10126, #10135, #10137)
• Bump CoreMods to 5.2.4, which adds new features such as ES6, better documentation, and long-awaited bug fixes (changelog, #10266)
