Olaf's Relatively Placed Blocks 2.0.0

New

• Orthostats (vertical slabs). Every slab, vanilla or from other mods, now has an orthostat version. It uses the slab's look, tool, drops and settings. To craft them, stack 3 slabs in a column; you get 6 orthostats.
• Mixed slabs. Two different slabs can share one block space, one in each half. Two orthostats can do the same.
• Pots in front of barriers. A flower pot (or potted plant) can now share a space with a fence, pane, wall or fence gate. It sits on your side of the line. Pack makers can add more blocks through the relative_placement_beside_barrier tag.
• New versions. Minecraft 1.20.1 and 26.3 are now supported.

Fence, pane, bar and wall connections

• Barriers in half a shared space now line up with their neighbours. Before, their arms would stop short, poke through, or cross over at corners.
• Corners, T-junctions and joins onto ordinary barriers now connect cleanly.
• A new barrier placed next to a half-space barrier moves into the matching half, so the line stays straight.
• If you break the block a barrier was sharing with, the barrier stays in line with its row. It only moves back to the middle once nothing in its line is left beside it.
• When a shared-space barrier meets an ordinary line side-on, it runs straight into it. It no longer zig-zags.
• Different kinds of barriers in the same space (for example a fence and panes) no longer cut across each other. Panes on either side of a T now connect properly.
• Outlines, collision and the crosshair now match the shape you actually see.

Fixes

• Turning a space into a shared space no longer makes it flicker.
• Clicking with an empty hand now works on blocks in a shared space, so gates open and levers and buttons flip.
• An item use that failed on a block in a shared space no longer runs a second time.
• 26.3: the mining sound now plays from the block in the shared space.
• 26.1 / 26.2 / 26.3: fixed a crash that showed up as "Failed to load world" (it happened while the game set up the orthostat recipes).
