+## Latest Updates (v1.1.2)
+
+- **reload**: `violation.decay_interval` changes now take effect immediately — the decay task is cancelled and recreated on every `/xac reload`.
+- **NoFallCheck**: Added Beds (all 16 colour variants via `Tag.BEDS`) and Powder Snow to the list of blocks that cancel fall damage. Eliminates false positives when players land on these blocks.
+- **config.yml**: Removed orphaned `allow_jump_crits` key from `checks.critical` section (was removed from code in v1.1.1).
+- **JesusCheck, GlideCheck**: Eliminated `Math.sqrt()` from hot-path threshold comparisons.
+
 ## Latest Updates (v1.1.1)
 
 - **CriticalCheck**: Removed dead code — the "no-air crit" detection branch was logically unreachable because `isCritical=true` requires `!isOnGround`, making the subsequent `isOnGround` check always false. The check now only flags "crit while sprinting" (the only branch that could actually fire). Removed `allow_jump_crits` config key. (Future enhancement: Option B damage-ratio detection.)
