  too dark.

* Thu Sep 10 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.22-1
- SOMA: fixed a crash loading the real apartment map right after the
  intro slideshow.

* Wed Sep 09 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.21-1
- SOMA: fixed a real bug that could cause the game to hang on a black
  screen right after launch instead of showing the boot splash.

* Wed Sep 09 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.20-1
- SOMA: fixed a real bug that could rewrite files inside your Steam
  install directory on launch, which could trigger a "files failed to
  validate" repair in Steam.

* Wed Sep 09 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.19-1
- SOMA: fixed real-time lights being silently culled and never rendered

  a further fix is in progress.

* Wed Sep 09 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.18-1
- SOMA: fixed a crash loading the real apartment map (collision-only
  meshes like block_box's could read a negative array index).

* Wed Sep 09 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.17-2
- SOMA: fixed an instant crash on launch ("Could not load vertex buffer
  from mesh 'core_box.dae'") by deploying the same compat meshes the
  Rebirth/Bunker launchers already deploy.

* Wed Sep 09 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.17-1
- SOMA: fixed a real bug causing the game to rewrite its own real Steam
  files on every launch, which could trigger repeated file-validation
  failures.
- Engine binaries can now run against game data anywhere, without needing
  to be copied into the game's own install folder.

* Tue Sep 08 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.16-1
- SOMA: fixed the boot splash order, added the animated loading icon,
  and made loading genuinely gate skipping.
- SOMA: fixed missing sounds (phone ring, car horns, and other ambient
  sounds) and added audio pause when the window loses focus.
- SOMA: the intro slideshow now paces correctly, and Simon's phone call
  waits for the player to actually answer it.
- SOMA: added a player HUD, a real in-game pause menu, and a difficulty
  select screen for New Game.

* Mon Sep 07 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.15-1
- Fixed a bug that could corrupt the real Steam game files during testing;
  test tooling now refuses to run against a real install.
- SOMA: real animated loading icon, fixed menu music/ambience lingering
  into gameplay, fixed overlapping intro voice-over, real Options toggle
  switches and gamma-screen instructions, live resolution changes, and a
  new in-game pause menu (Escape).
- SOMA: added the apartment map's phone-call scene.

* Sun Sep 06 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.14-1
- SOMA: fixed the remaining HDR-precision bug affecting box lights and
  fog areas (matches the earlier point-light/transparency fix).

* Sun Sep 06 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.13-1
- SOMA: fixed severe map-rendering corruption and invisible New Game
  intro slides/subtitles.
- SOMA: real Options settings now actually work (resolution,
  anti-aliasing, field of view, subtitles, mouse sensitivity,
  rebindable keys).
- SOMA: fixed the loading-bar's position/size on the boot screen.

* Sat Sep 05 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.12-1
- SOMA: real boot/splash sequence with loading bar, floating debris
  effect, custom cursor, real Options menu widgets and working menu
  sounds, and a New Game intro slideshow.
- Partial fix for a window-resize rendering bug (still open for SOMA
  specifically; fixed for Amnesia: The Dark Descent).

* Sat Sep 05 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.10-1
- SOMA: menu music, a first-boot gamma calibration screen, a real
  Options menu (volume/gamma/vsync/fullscreen), and a real player
  controller (gravity, walking, jumping, collision) on gameplay maps.

* Fri Sep 04 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.9-1
- Fixed a window-resize bug (e.g. a tiling compositor fullscreening the
  window) that left rendering pinned to a stale-sized corner with the
  rest of the screen black.
- Fixed the Launcher writing its config/log outside the XDG Base
  Directory spec.
- SOMA: New Game now loads the real declared start map instead of a
  hardcoded wrong one.

* Fri Sep 04 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.8-1
- SOMA: rewrote the main menu to match the real game's own menu logic,
  read directly out of its shipped AngelScript source and debug-info
  binary - correct 1280x720-scaled layout, real background/dirt-corner
  art, an animated glitch title and cathedral ghost-trail effect, and
  real text-based menu buttons with the real teal highlight bar.

* Fri Sep 04 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.7-1
- SOMA: the main menu now uses SOMA's own real background/title art
  instead of a generic placeholder.

* Fri Sep 04 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.6-1
- SOMA: fixed the splash logos (wrong texture format, oversized second
  logo) and added a real interactive main menu (New Game / Quit).

* Fri Sep 04 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.5-1
- SOMA: added OPENHPL_SOMA_MAP env var to load a real map on normal boot.
- Trimmed this file and README.md.

* Fri Sep 04 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.4-1
- SOMA now renders real lit, textured, correctly-exposed geometry: fixed
  missing light/skybox/fog shader uniforms, applied SOMA's own per-area
  exposure data, and fixed an HDR precision bug in glass/translucent
  materials. See PORTING_NOTES.md for details.
- Headless test runs no longer wake the screen, play sound, or run more
  than one instance at once (dev/CI tooling only, no effect on normal play).

* Thu Sep 03 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.3-1
- Added a regression test suite (CTest) covering string/path helpers and
  SOMA's shader transpiler.
- Added a "Show FPS" checkbox to Options > Graphics.
- Minor rendering optimization: skip redundant texture-unit rebinds.
- Wayland: exclusive fullscreen now degrades correctly; Launcher window
  now has a proper app-id.
- Fixed two headless-automation-server crashes/bugs (dev tooling only).
- SOMA/Rebirth/Bunker: extended the shader transpiler, added entity/area
  loaders for Rebirth, fixed Bunker's spawn point. All three remain
  tech-preview, pre-alpha.

* Wed Sep 02 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.2-1
- Save games, config, logs, map caches, and screenshots now follow the
  XDG Base Directory spec instead of scattering across
  ~/.frictionalgames, the Steam game directory, and ~/Desktop. Existing
  saves are migrated automatically on first run.

* Wed Sep 02 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-12
- Fixed the in-game UI Scale setting at 2x/3x/4x: several screens (loading
  screen, HUD, inventory, journal, credits) rendered oversized and spilled
  off-screen. Also fixed a crash in the headless test server hit while
  verifying this.

* Wed Sep 02 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-11
- Fixed desktop-entry icons often showing the generic placeholder instead
  of each game's real Steam thumbnail.
- Added "Open HPL" branding/keywords to all desktop entries.

* Wed Sep 02 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-10
- Fixed the splash/pre-menu screens not skipping on most keypresses.
- Added an opt-in hidden-window mode to the headless automation server.
- Added three more EXPERIMENTAL desktop entries (SOMA, Amnesia: Rebirth,
  Amnesia: The Bunker), each a native aarch64 Phase 0 scaffold: boots the
  engine against that game's real data and shows one map via a free-fly
  debug camera, no player/menu/scripts yet.

* Tue Sep 01 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-9
- Fixed the UI Scale setting (added in 1.3.1-7): most menus and the splash
  screen were unusable at 2x/3x/4x.

* Tue Sep 01 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-8
- The Launcher and game windows now run as native Wayland clients instead
  of through XWayland.

* Tue Sep 01 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-7
- Fixed the resolution dropdown dropping options shared between two
  displays.
- Added an in-game UI Scale control (Options > Graphics).

* Tue Sep 01 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-6
- Fixed a real engine bug: teleporting the player mid-fall could tunnel
  through floor collision at the destination.

* Mon Aug 31 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-5
- Re-added an experimental "Amnesia: A Machine for Pigs" entry, this time
  running Dark Descent's real native binary against AMFP's data (no x86_64
  emulation). Level data loads and scripts run; some collision/gameplay
  bugs remain.

* Mon Aug 31 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-4
- Removed the box64-based Machine for Pigs entry - this project is
  native-aarch64-only, no emulation fallback.

* Mon Aug 31 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-3
- Source refresh only; no shipped-binary changes. Picks up early
  reverse-engineering work on AMFP and SOMA.

* Sun Aug 30 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-2
- Split the desktop entry into per-game entries; added a soft box64
  dependency for the (since-removed) Machine for Pigs entry.
- Fixed the Launcher hardcoding the wrong binary name on non-x86 targets.

* Sun Aug 30 2026 Lachlan Marie <lchlnm@pm.me> - 1.3.1-1
- Renamed from amnesia-dark-descent to open-hpl. No functional changes.
