0.6.1-alpha+1.21.1

FIXED

• Placing a fitting post beneath a lowered slab now uses the available space correctly.
• Deep side placements follow the aimed face and stop at the actual landing surface.
• Placing supported blocks on farmland or dirt paths converts the support to dirt when appropriate; crops retain their farmland.
• Tilling or shovelling a lowered block preserves its placed height.
• Lowered campfire particles now rise from the visible fire.
• Refresh the first rendered frame immediately after a predicted placement.
• Correct Sable single-block object lighting above lowered solid surfaces — reported by @ALEILGOD (#87).

IMPROVED

• Reduce repeated client work by avoiding copies of unchanged height-marker data.
• Release labels now use major.minor.patch plus a maturity label, without numbered alpha or beta counters.

NEW

• Fence posts now meet a nearby slab ceiling across a half-block gap. The post keeps its placed height, and its visible connection can be targeted correctly.

Grass flicker at chunk boundaries remains under investigation. Reported by @ALEILGOD in #87; the issue remains open.
