Slabbed

First Slabbed build for Minecraft 1.21.2 and 1.21.3, one file for both (1.21.3 is a two-fix hotfix of 1.21.2; part of the promised 1.21.2–1.21.10 range). It carries the full feature set of the 1.21.1 line: placement heights are recorded where you aim and kept for good, lowered slabs support the same objects, rails slope to meet their neighbours, fence posts meet a nearby slab ceiling, hung decorations keep their seat.

Needs Fabric API 0.114.1 or newer.

• The 1.21.2 game refactors (block neighbour updates carry a wire orientation, minecart movement moved to a controller, redstone wire power moved to a controller, entity renderers work from render states, world events moved to their own handler) are followed where Slabbed hooks them; behaviour is unchanged.
• The experimental pale moss carpet, where enabled, follows the same rules as the other carpets on lowered slabs.
• The Minecart Improvements experiment is not covered: with it enabled, carts ride at vanilla height over lowered rails. Item frames keep the 1.21.1 line's behaviour (no render drop for frames without a remembered seat).

For Minecraft 1.21.2 and 1.21.3 with Fabric (Fabric API 0.114.1 or newer, Java 21).

This is an alpha. If anything misbehaves, please open a report at https://github.com/peetsamods/slabbed/issues with your game version, loader and Slabbed version.
