v0.7.4

Fixed

• ACC brake bias now matches the in-car dash: the per-car offset from the official documentation is applied to the raw shared-memory value.
• Changing car without restarting the game kept the previous car's power scale, ideal pressures and calibrated maxima — all of it re-seeds on a car change now.
• Brake bias read one point low (a 69 % setting showed 68 %) — the readout truncated the game's value instead of rounding it.
• Fitting a compound the car files don't describe kept the previous compound's temperature window instead of the default curve.
• AC Rally's spec sheet is picked up when the game fills it in, instead of only at connect time.

Changed

• Per-car power and tyre-temperature colour curves rebuild only when the curve changes, not on every repaint.
• Docs: the suspension bar is scaled to the car's mechanical travel or the session's deepest compression — never to the setup's packer range.
• Docs: the suspension reference self-calibrates on ACC and AC EVO, and one hard kerb strike can set it for the rest of the session.

Full Changelog: v0.7.3...v0.7.4

v0.7.3

Fixed

• AC Rally was not detected at all (regression in 0.7.0) — its acr.exe process was missing from the detector's list of known executables.

Changed

• Game auto-detection now identifies the game solely by its executable, matched exactly against the running-process list: AssettoCorsaEVO.exe, acs.exe/acs_x86.exe, acc.exe/AC2-Win64-Shipping.exe, acr.exe. Also adds AC1's 32-bit acs_x86.exe, which was never matched.
• Detection no longer inspects shared memory, and no longer guesses between ACC and AC Rally from tyre-temperature units. A stale acpmf_* mapping — left by a crashed game or held open by Content Manager / SimHub — is never mistaken for a running game.
• A game sitting on its main menu is detected immediately, with no 10-second wait before the overlay commits to ACC.
• The overlay now appears as soon as the game process starts rather than waiting for its first telemetry block; widgets show no data until the game publishes, and the readers connect on their own once it does.

Full Changelog: v0.7.1...v0.7.3

v0.7.2

Fixed

• Bundled .exe crashed at launch with No module named 'PySide6.QtOpenGL' — the build stripped QtOpenGL/Qt6OpenGL.dll, which the VR overlay imports at startup. Both are now kept in the bundle.

Full Changelog: v0.6.6...v0.7.2

v0.7.1

Added

• Per-widget show/hide: a Widgets submenu in the tray VR and Windows menus toggles each panel (engine, inputs, four wheels); persisted.
• VR widgets wrap around the viewer on a cylinder — the corner panels turn to face inward — instead of sitting on a flat plane.
• Tray VR submenus Spread (sideways fan-out) and Distance (panel distance), plus Size in VR — each persisted, applied live.
• Global hotkeys Ctrl+Shift+C (toggle click-through) and Ctrl+Shift+S (cycle widget size XS → S → M → L → XL, wrapping).
• Global VR hotkeys Ctrl+Shift+P (placement toggle), Ctrl+Shift+W (spread) and Ctrl+Shift+D (distance); each cycles its tray submenu.

Changed

• VR submits each widget as its own native-resolution quad instead of one screen-size canvas — smaller uploads, and a hidden widget costs nothing.
• Tray Windows and VR categories are mutually exclusive: Windows greys out while VR renders, VR greys out on the desktop overlay.
• Reset restores the Inputs widget's default position but leaves it hidden (it's off by default); use the Widgets toggle to show it.
• Hotkeys moved from Ctrl+Alt to Ctrl+Shift (less contested by gaming peripherals and vendor overlays); logging is now Ctrl+Shift+L.
• Full global hotkey set: Ctrl+Shift + R reset, C click-through, S size, L logging, P/W/D VR placement/spread/distance, Q quit.
• Each hotkey is inert while its tray entry is greyed: reset/size/click-through need widgets placed, logging a detected game, VR keys a live headset.
• Tray Data category (Polling Hz, logging, Open logs folder) and Ctrl+Shift+L stay disabled until a game is detected and telemetry flows.

Fixed

• VR HUD widgets were clipped and shrank at non-default Size — fixed by a max-size texture with the widget centred and full (not sub-rect) bounds.
• ACC is no longer detected from a stale acpmf shared-memory tag; a live ACC process must be running before its physics block is trusted.
• Global hotkeys are released on every quit path, not just closeEvent (skipped by QApplication.quit()), avoiding err 1409 on the next launch.
• Hotkeys register per-combo with failures attributed individually, so one GetLastError() no longer misreports a single conflict as total failure.

Full Changelog: v0.6.6...v0.7.1

v0.6.6

Added

• Auto-update on launch: hits GitHub releases API, downloads the new LiveTelemetryEvo-<version>.exe next to the app; skips already-downloaded files.
• Streams via a .partial sibling + atomic rename so a crash mid-download never leaves a half-file under the final name.
• Tray entry Check for Updates — 4 states: idle → Checking... → Downloading... → Restart to Update (launches new .exe, quits).
• Tray balloon notification when a fresh download completes; silent on already-on-disk / up-to-date / offline paths.
• New overlay.updater module — UpdateChecker worker + UpdateController (state machine + Qt signals the tray menu subscribes to).

Changed

• PyInstaller spec keeps Python's stdlib SSL DLLs (libcrypto-* / libssl-*) for urllib HTTPS; Qt6Network.dll + TLS plugins stay excluded.

Full Changelog: v0.6.5...v0.6.6

v0.6.5

Added

• Global hotkey Ctrl+Alt+C toggles CSV logging on/off, mirroring the tray Start logging / Stop logging action.
• Polling and rendering decoupled across threads — source runs on its own QThread; UI repaints at QScreen.refreshRate() Hz.
• FrameBus transports the latest snapshot (deep-copied, under lock) to the UI and a bounded queue to the CSV writer thread.
• Tray submenu Polling Hz — 30 / 60 / 100 / 120 / 144 / 250; choice persisted via settings.json.
• Tray actions Start logging / Stop logging + Open logs folder; CSV writes on a dedicated thread off the polling worker.
• CSV schema auto-built from dataclasses.fields() on TelemetryFrame; new fields appear in the next session's file automatically.
• New overlay.paths module — positions.json and logs/ sit next to the executable (CWD in dev); LIVE_TELEMETRY_DATA_DIR overrides.
• Countdown screen shows the detected game name above the digit, both centred at the detection-screen font size.
• AC EVO: KERS fields exposed (has_kers, battery_temp_c, lap-cap flags, overtake/heat/deploy/recharge maps); chips KMAX/CMAX/OT/HEAT.
• AC1: per-car ACD data plumbed to widgets — torque curve drives rev-bar tint, per-compound curves drive tyre temps, ideal psi surfaced.
• WheelData.susp_v flag — true when susp_m_t is rolling-max calibrated; suspension mid-band paints blue in that mode.

Changed

• AC1 boost bar: dropped static.maxTurboBoost seed (unreliable on mods); right-edge now tracks rolling max of observed turbo_boost.
• Engine rev-bar colour: uses per-car torque curve from ACD on AC1; otherwise self-calibrates from observed current_bhp peak RPM.
• Boost and KERS battery bar slots fully transparent on NA / ICE-only cars — no more black stripes at the top of the engine widget.
• AC EVO ABS blink merges all three signals (absInAction int, abs intensity float, graphics.abs_active bool); same logic for TC.
• Per-wheel ABS heuristic on AC EVO uses documented slipRatio (not wheelSlip); threshold 0.10 → 0.03 — fires before the wheel is lost.
• Brake disk now always rendered on AC1 (neutral white base + blue ABS blink); other games keep temp-curve tint + white blink.
• AC1 + AC EVO: per-wheel body-roll height correction — per-axle rideHeight split by relative suspension travel across the axle.
• Engine max_turbo_boost default 1.2 → 0.0 so NA cars on every source hide the boost slot via the existing > 0.05 gate.
• Default polling rate moved from CLI-only --hz to a persisted setting changeable at runtime; --hz 0 (new default) uses persisted value.

Fixed

• AC1 suspension calibration: removed 5 % headroom and 2× initial seed; static suspensionMaxTravel now trusted as-is. ACC/Rally too.
• AC1 tyre-wear bar: raw tyreWear is a grip/health value (~0.06 useful range), not a linear 0-100 % counter — remapped onto 0..1.
• KERS deploy-power on AC EVO now gates on physics.ersIsCharging instead of inferring direction from SoC drop; robust at SoC 0 / 1.
• has_brake_temp=False on AC1 no longer hides the whole brake column — icon stays for ABS/lock blink, only the °C label is suppressed.
• Dropped wasted writes to brake_t / brake_t_norm on AC1 (consumed only when has_brake_temp=True).
• Sibling project fix: lt_wheel_info.py body-roll correction mixed Python-API and SHM reads across wheels — now consistent on both sides.

Full Changelog: v0.6.0...v0.6.5

v0.6.0

Added

• --source auto (now default) detects the running game via SHM tag namespace + process snapshot; shows "Detecting AC Environment..." until found.
• Assetto Corsa Rally support via --source acrally flag.
• Assetto Corsa Competizione support via --source acc flag.
• Original Assetto Corsa support via --source ac1 flag.
• Tire silhouette rotates by per-wheel camber on each wheel widget.
• Contact-patch bars below each tire encoding inner/middle/outer load distribution.
• Brake-pad and disc wear bars on each wheel widget, self-calibrated against per-wheel max observed since session start.
• New pad_w / disc_w fields on WheelData, populated from ph.padLife / ph.discLife.
• Per-zone temperature readouts (inner / middle / outer / core) on the tyre silhouette, with luminance-based text colour.

Changed

• WheelData gains has_wheel_load, has_ride_height, has_camber capability flags; widgets hide indicators when a source lacks the signal.
• Removed the trapezoidal camber strip; tire rotation plus contact bars replace it.
• IMO temp grid always shows the inner face on the screen-centre-facing side of the widget.
• Wheel widget logical height bumped 271 → 316 to fit the new bars and rotated tire.
• Synthetic source: right-side camber sign flipped; corner-load → camber coupling rescaled.
• Brake icon no longer shrinks with disc temperature; temperature drives only tint, wear moves to the dedicated bars.

Fixed

• Per-face tyre temperatures now read from graphics-block TyreState on AC EVO instead of the dead legacy AC1 slots.
• Brake icon now falls back to interpolating the brake curve from raw temp when brake_normalized_temperature is missing.
• Tyre-wear restyled as a horizontal "Tire Wear" bar stacked under the existing Disk/Pads Wear rows; gated on has_tire_wear (hidden on AC EVO).
• AC1 hides the Disk/Pads Wear bars — AC1's SDK predates padLife / discLife, so the bars previously rendered a stuck-fresh value.
• AC1 hides the brake icon entirely (icon + label) since brakeTemp is never written by the game; lock/ABS blink disappears with it on AC1.
• Wear bars now space themselves evenly between the brake column and pressure icon — a lone visible bar pins to the top of the available height.
• AC1 contact-patch middle bar no longer collapses: new has_pressure_norm flag neutralises the pressure axis when the norm is a rough synthesis.
• AC1 reads per-car spec data from data.acd: real per-axle ideal pressure, raw torque LUT for live BHP/torque, per-compound tyre thermal curves.
• AC install auto-detected via Steam registry + libraryfolders.vdf; honours LT_AC_PATH env override and falls back to the default Steam path.

Full Changelog: v0.5.0...v0.6.0

v0.5.0

Added

• System-tray icon with a context menu: Reset positions, Click-through
  toggle, Size submenu (XS/S/M/L/XL), Quit. Left-click and right-click
  both surface the menu; tray icon shares the same source PNG as the EXE icon.
• Two new global hotkeys (Win32 RegisterHotKey, fire even with the game
  focused): Ctrl+Alt+R resets every widget to its default position;
  Ctrl+Alt+S cycles widget size. Each tray entry shows its shortcut.
• Phase 1 — driver-aid chips on the engine widget: ESC, LC (launch
  control), DRS (bright when deployed, dim when only available), ERS
  (charging), WW (wrong way), INV (lap invalidated), LAST (final lap).
  Strip auto-compresses width when many fire at once.
• Phase 2 — analog readouts row on the engine widget: water / oil temp,
  oil / fuel pressure, exhaust temp, battery V, fuel L, brake bias %F. Cells
  hide automatically when the source publishes nothing for the current car.
• Phase 3 — new inputs widget (top-centred): pedal bars (THR/BRK/CLU/HBR),
  signed steering bar, FFB clipping indicator, G-meter circle with reference
  rings, five-zone damage chips, tyres-off-track count, performance-mode
  label. Hidden by default in 0.5.0 — Ctrl+Alt+R brings it on screen.
• 18 MDI icons rendered into resources/img/ via a new fetch_icons.py
  helper (downloads SVGs from Iconify, rasterises to 256×256 PNGs through
  QSvgRenderer — no extra dependencies).
• GitHub Action (.github/workflows/release.yml) that builds the Windows
  executable and publishes a release on every v* tag push.

Changed

• Removed the floating reset and size buttons from the overlay itself —
  their job is now done by the tray menu plus the new hotkeys.
• App icon replaced with the higher-resolution LT branding (256×256);
  tray and EXE share the same source file so they always match.
• Engine widget logical height grew from 120 to 148 px to fit the new
  Phase 2 readouts row; the bar still anchors to the bottom of the screen.

Fixed

• Tire temperature grid showed thin transparent seams between colours at
  fractional logical coordinates (anti-aliased edges of adjacent rects).
  AA is now disabled for that grid; aliased fills snap flush.
• Tray context menu was being covered by the overlay every second when the
  topmost-reassertion timer fired. The reassertion now skips while any
  popup widget is active.
• build.py now bundles resources/icon.png into the EXE so the tray
  icon resolves at runtime (previously only the embedded .ico was set,
  so the tray was iconless in the frozen build).
