+## [0.9.5] — 2026-08-15
+
+### Added
+- **Boss-room loading overlay** — first visit of a boss room holds combat in `bossload` for at least 1s while the boss action sheet is warmed (decode + GPU upload) so the roar is not cut by the hitch. Re-entering a visited boss room skips the overlay. A failed sheet cannot deadlock the screen.
+
+### Changed
+- **Elite Brood Sac summons** — an elite sac now seeds 4–6 minis per cycle (normal remains 2). Wave elite rolls still exclude Brood Sac; debug/other elite paths are the intended case. Death burst is unchanged (4).
+
+### Removed
+- **Redundant RUN DATA pressure multiplier** — the `×N.NN` number next to score is gone; `PRESSURE NN%` and the bar remain.
+
+
+## [0.9.1] — 2026-08-13
+
+### Changed
+- **Static wall bands cached** — wall tiles render once into an offscreen canvas layer (`G.wallLayer`) and are composited each frame; the layer is invalidated on room entry (`G.wallLayerKey`), so door sprites stay dynamic.
+- **Sprite draw fast path** — `Sprites.draw` issues a single `drawImage` when a sprite has no rotation, scale, alpha, or flash.
+- **Canvas rect cached** — the input canvas `getBoundingClientRect` is cached (`Input.updateRect`) and refreshed on canvas fit instead of every frame.

 MeatSlicer is an endless top-down arena roguelite. You are the Butcher, descending floor by floor through an infinite meat-locker hell: clear rooms of flesh-hungry horrors, draft mutations, stack grotesque passive items into a broken build, kill the boss, take the stairs. The descent never ends — the only question is how deep you get before you're butchered, and whether your score becomes the new best cut.
