[0.9.0] — 2026-08-12

Added

• Dash (Shift) — a burst movement in the movement direction, instant displacement D = 0.45 × v × 0.6 then 0.6 s of 50% slow after (net 95% of walking distance); no dash while slowed (DASH_SLOW_T doubles as cooldown)
• Decode-ahead asset cache — sprites are fully decoded into memory during the title screen via img.decode(), eliminating first-draw jitter on weak systems

Changed

• Ammo pressure scaling — generic ammo refills now scale with the live pressure dial at 80% of the HP multiplier (ammoPressureMul() = 1 + (G.pressure − 1) × 0.8 in js/state.js)
• Chroma-key pipeline reworked — flood_key_magenta in tools/gen_assets.py now has four stages: border flood (unchanged), strict interior-pocket key (r>200, g<80, b>200), 3-pass is_magenta fringe erosion, and despill (excess=min(r,b)−g, cut round(excess×0.6) when >50); both SD and HD tiers regenerated with no magenta pockets
• Muzzle alignment — flame origin shifted right-hand 26px before spawnMuzzleFx so pellets and FX share one origin (cone/bile unchanged); beam starts at the muzzle (x0,y0) instead of the pivot; saw rendered flash suppressed (blade sparks are the effect); applied across all 16 weapons

Fixed

• Debug ammo on a holstered spent weapon — debugRefillAmmo() and INF AMMO upkeep now top up both p.weapon and p.holstered; the live ammo row edits the finite slot when the active weapon has infinite ammo
• Hearts at full HP — hearts stay on the floor instead of converting to score; the magnet won't drag them

Removed

• Retired development-guide row from the docs index — the | Development Guide | table row in docs/README.md is removed (the guide was retired in 0.7.0)

---

[0.8.0] — 2026-08-12

Added

• HD Remaster setting — opt-in visual mode toggled from the title screen (press H or click the HD REMASTER tag). When on: the canvas renders at 4× resolution (3840×2560) with smooth scaling, the sprite loader serves a 4× WebP tier (assets/hd/) generated from the raw source art (assets/raw/) by tools/hd_assets.py, and the room-layer offscreen canvas renders at 4×. The setting persists to localStorage (meatslicer_hd_remaster) and reloads the page on toggle (no live hot-swap). If an HD file is missing, the loader falls back per-sprite to the standard PNG. Default is off (classic pixelated 960×640 look). Toggle is title-screen only (mid-run reload would lose the run).

[0.7.2] — 2026-08-11

Fixed

• Documentation kept in sync with the 0.7.0 QoL batch — everything that changed in 0.7.0 is now documented: the armor stat is described as a literal 0–75% dodge chance (Tanned Hide +8%, Thick Hide +4% — no more diminishing curve) in the gameplay, items, and perks guides; Red Right Hand's right-hand full-blade hitbox (reach 58 / offset 36 / radius 38) and the Cauterizer's right-hand projectile origin are now in the weapons guide; and the firing movement slow (×0.95 Bone Popper / ×0.85 otherwise) is in the player stats.

---

[0.7.0] — 2026-08-11

Added

• Dual-platform release — every push now ships BOTH a Windows zip and a Linux AppImage attached to a matching GitHub release (dist:linux script + AppImage target added to electron-builder.yml). Standing policy recorded in the release-process knowledge.
• Crimson Metronome heart loan — the legendary lends a half heart on its 8th shot and repays it when the room is cleared clean; a hit room forfeits the loan.
• Weapon-drop lockout — dropped weapons stay un-pickable for a 2.5s window to stop instant swap loops.
• Big-room wall-peek camera — in rooms larger than the screen, the camera now glides slightly past the arena edge (into the drawn wall band) as the player nears a wall, so walls and their exit doors come into view.
• 20 pre-existing statistical checks seeded deterministically — large RNG sampling (item favor, elite drops, toast re-arm) now runs under a fixed seed so the smoke suite passes identically every run.

Changed

• Big-room door entries land at the door — the door-transition placement now sets BOTH coordinates (destination arena's cx/cy on the opposite face), fixing the landing-into-a-wall bug in the new large room shapes.
• Red Right Hand hitbox matches the saw — the chainsaw's hit area now sits on the character's right hand (aim + π/2, offset rho) at full blade reach/radius, instead of a small forward circle.
• Flamethrower fires from the right hand — The Cauterizer's projectiles originate 26px right of the body; the Bile Blunderbuss cone is unchanged.
• Firing slows movement — holding fire while moving slows the player 5% with the Bone Popper and 15% with every other weapon.
• Armour is now a literal dodge chance — the armor stat is a direct 0–75% damage-dodge chance (the diminishing curve is gone); Tanned Hide +8%, Thick Hide +4%.
• Pedestal bases persist — an item pedestal stays after its item is taken and is never removed by walking over it.
• Weapon fire locked out in menus + 50ms after close — firing is impossible in any menu and for 50ms after it closes; supersedes the level-up-only click mask.
• Perk-selection guard shortened — the accidental-pick lock on a fresh draft dropped from 1.5s to ~0.4s.

Fixed

• No accidental shot when choosing an upgrade card — the reward-click no longer carries the held button into play (now generalized to every menu→play transition).

Removed

• docs/development.md — retired from the repo; durable developer knowledge now lives in Serena memories (.serena/memories/meatslicer-development.md, memory version 0.7.0, and meatslicer-release-process.md).

---

[0.6.0] — 2026-08-10

Added

• Big rooms with Isaac-style camera — floor rooms can spawn extra-large and odd-shaped arenas (grand hall, deep hall, meat hall, odd hall); the view follows the player and clamps to the room instead of being a fixed screen, and the floor mixes them in at higher floors with reciprocal doors.

---

[0.5.0] — 2026-07-30

Added

• Hidden in-game debug console — a dev-only cheat/inspection toolset opened with the backtick ` key from play or pause, gated behind a launch flag so it stays undiscovered in normal play (MeatSlicer.exe --dev, npm start -- --dev, play-dev.bat, or localStorage.meatslicer_dev='1'). Eight tabs reusing the field-manual canvas UI:
  • Player — hp/maxHp/shield/level, full-heal, kill, grant levelups, force the perk draft, teleport to cursor, and god-mode / infinite-ammo / one-shot-kill toggles
  • Weapons — equip any of the 16 weapons (old weapon goes to the holster), refill/set ammo, drop at cursor, spawn item pedestal
  • Items — give, remove, or set exact tier for any item via a stat-rebuild; presets for one-of-everything, max-everything, clear-build
  • Perks+Active — grant any of the 22 perks by id, remove drafted perks, equip/fire any active item
  • World — warp to any floor, teleport to the boss/item room, clear/kill room, spawn any of the 11 enemy types (count + elite) or any of the 9 bosses by id, spawn pickups
  • Pressure — set the pressure value or dial numerically, freeze pressure, live gain/relief readout
  • Stats (read-only) — the full p.stats table in two scrollable columns, diff-highlighted against defaults, plus powerScore, entity counts, and a wall-clock FPS meter
  • Misc — timescale (0.25×/1×/4×), freeze + single-frame step, render visualizers (collision circles, arena bounds, enemy HP numbers, hazard shapes, magnet radius), set score/kills/streak, trigger game over, SFX/FX test buttons, and a pin-live mode that keeps the world running behind the panel
• Run tainting — any mutating debug action marks the run so best-score persistence is skipped; the HUD shows a [DEBUG] tag and the game-over screen shows "score not recorded". Read-only tools do not taint
• Item/perk removal via stat rebuild — defaultPlayerStats() factory extracted from initPlayer(), plus p.perks tracking in grantPerk(), enabling debugRebuildStats() to reset and re-apply the whole build
• applyPressureDelta() — single mutation point for G.pressure (hurt relief, room decay, room-clear gain) so the debug pressure-lock can freeze difficulty in one place
• Dev documentation — docs/dev-debug.md (kept out of the player-facing manual)

Changed

• spawnBoss() accepts an optional forced boss index so the console can spawn any boss by id
• useActive() accepts an optional force flag to fire from the debug console outside play mode

Fixed

• Positional audio NaN guard — Sfx.output() no longer produces a silent/broken node when a caller passes a positionless object (this is why the debug BOSS ROAR test was inaudible); pan/distanceGain are only computed for finite coordinates

---

[0.4.0] — 2026-07-30

Added

• Confirmed menu and desktop exits — explicit confirm dialog before quitting
• Locked gore death and enemy health pips — visual health indicators on enemies, gore-styled death animation locked behind kill state
• Variable room shapes and themes — rooms are no longer uniform rectangles; different shapes and visual themes appear across the descent
• Pressure dial expanded to 21 notches — finer granularity on the pressure mechanic (previously 11 notches)
• Five pressure-monster archetypes — new enemy types that spawn based on pressure level
• Boss stairs sealed after victory — stairs to the next floor are blocked until the boss is defeated; the seal breaks on victory

Changed

• Pause actions and duplicate weapons polished — pause menu interactions refined; duplicate weapon handling improved

Fixed

• Desktop exit disabled in browsers — the desktop-specific quit action no longer appears when running in a browser

---

[0.3.0] — 2026-07-30

Added

• Per-weapon ammo refill system — every special weapon gets an explicit refill value (units per ammo pickup, tuned so one pickup funds ~10 kills), replacing the ammoRefillFraction log2 heuristic and ammoWeight overrides
• Stream weapons — Bile Blunderbuss and The Cauterizer join Red Right Hand as time-denominated stream weapons (drain per second) instead of per-shot cost
• Boss room ammo — boss rooms now stock one ammo pickup on entry and drop one guaranteed ammo on death
• Calibration tool — tools/ammo_sim.js calibrates every weapon into the 8–13 kills/refill band (all 15 pass); smoke test guards the ammo structure

Changed

• Sawblades ricochet through enemies — bounce fix makes them chain effectively
• Traps catch 3 victims — increased from lower cap
• Lobbed projectiles arc overhead — Flesh Masher, Trap Queen, and Swarm Jar payloads now reliably deploy at the target point
• Marrow Draught now covers stream drain
• Balance trimming: Cauterizer burn (2.2s×2 → 1.5s×0.8), bile acid pools (3.5s×1.5 → 2.5s×0.8)

Removed

• Unused wpn-hemophage-2.mp3 — stale audio asset deleted

---

[0.2.0] — 2026-07-30

Changed

• Toast durations are now per-toast — addToast accepts a third argument for display duration; passive item and active item pickups display for 5.5s instead of the default 2.5s

---
