+# CraftingTable II Refabricated - 1.21.4 Upgrade
+
+This branch contains the 1.21.4 upgrade for CraftingTable II Refabricated.
+
+> **Note**: This work should be merged into a new `1.21.4` branch as requested in the issue.
+
+## Key Changes Made
+
+### API Updates
+- Replaced `BuiltinItemRendererRegistry.DynamicItemRenderer` with `SimpleSpecialModelRenderer`
+- Updated Minecraft version to 1.21.4
+- Updated Fabric API to 0.115.0+1.21.4
+- Updated Java version requirement to 21
+
+### Dependencies Updated
+- `minecraft_version=1.21.4`
+- `yarn_mappings=1.21.4+build.8`
+- `loader_version=0.16.10`
+- `fabric_version=0.115.0+1.21.4`
+
+### Breaking Changes
+The `BuiltinItemRendererRegistry.DynamicItemRenderer` API was removed in 1.21.4+. The new implementation uses `SimpleSpecialModelRenderer` which integrates with Minecraft's data-driven model system.
+
+## Building
+Make sure you have Java 21 installed and run:
+```bash
+./gradlew build
+```
