- Mod targets 26.2 and 26.1.2 (inheriting 26.2) with Fabric 0.19.5, Forge 65.1.3 and 64.1.4, NeoForge 26.2.0.89 and 26.1.2.116
- The 26.3 target reads the minecraft26_3 native access rules
- Per-version pack.mcmeta ranges for 26.2 and 26.1.2
- 26.2 and 26.1.2 test overlays and replacements for the pre-26.3 biome, spawn, carver and sign APIs
- NeoForge compiles against the loader's own ASM while the mod jar keeps the bundled ASM
- Mod targets list an ordered overlay chain; later overlays replace earlier ones and earlier source replacements apply to inherited files
- Forge and NeoForge metadata take their loader version range from the target
- The Fabric permissions library is bundled only for targets that declare it
- Dropped the 1.21.1 mods.toml copies that only differed in the loader range
- Build Fabric, Forge and NeoForge per target listed in gradle/mod-targets.json (1.21.1, 26.3)
- Add 1.21.1 adapter source overlays under adapters/*/src/versions/1.21.1
- Add verifyModdedMatrix and per-target Java runtime verification of loader jars
- Re-inject persistent dimensions from the levels-ready hook before the watchdog starts
- Wait for queued chunks and the final save before pregen completes
- Add the 1.21.1 data version and datapack supported_formats range
- Cascade regions whose sea or shore pool loses every biome
- Use Gson calls available on the 1.21.1 runtime
- Pass the modded loader into the generation registry so biome modifier output stays out of validation
- Cover Forge modifiers on climate, attributes, effects and features against the canonical definition
- The modded chunk generator hands VolmLib the bound loader for chunk-generation creature checks
- Each loader build tests its spawn position check: Forge and NeoForge fire MobSpawnEvent.PositionCheck and honor a denial, Fabric applies the vanilla rule and obstruction checks
- Fabric, Forge, and NeoForge build against Minecraft 26.3 with Fabric Loader 0.19.5, Forge 26.3-66.0.8, and NeoForge 26.3.0.33-beta
- Fabric API modules follow fabric-api 0.161.0+26.3, ForgeGradle is 7.0.40, and ModDevGradle is 2.0.147
- Loader metadata requires Fabric Loader 0.19.5, Forge 66, NeoForge 26.3, and Minecraft 26.3
- The mod resource pack declares formats 97.1 through 121.0
- The v26_3_R1 headless sources no longer unpack a version overlay
- The README lists the 26.3 loader targets
