Releases

This is a hotfix addressing a regression that caused the dashboard to break. The immediate trigger was an update pushed by the ag-grid team, but the underlying issue was on our side - CDN dependencies weren't pinned to exact versions, so any upstream update could silently invalidate our integrity checks.

Bug Fixes

• Dashboard scripts failing to load - ag-grid (the data table library used in the driver and engineer views) stopped loading after the CDN updated the file it was serving, causing an integrity check mismatch. All CDN-loaded libraries are now pinned to exact versions so this cannot happen again silently.

This release replaces the incorrect executable uploaded in v4.0.1. No application changes from v4.0.1 - only the packaged binary/version has been corrected. Below are the release notes from the previous release

This is a hotfix release focused on reliability and data accuracy, addressing a handful of bugs introduced or uncovered in v4.0.0.

F1 2025 Session Data Protection

• Just-in-case autosave -- F1 2025 has a game bug where a false session-start signal is sent just before the final classification screen, which previously caused all collected session data to be wiped before it could be saved. The app now detects this pattern and automatically saves your data as a precaution, so your race results are no longer lost. This can be turned off under Save Data -> Just-in-case autosave in settings.

Data & Display Improvements

• Tyre wear MFD page now defaults to showing the maximum wear rate across all four tyres. Max wear rate is a more intuitive and commonly used metric -- it tells you which tyre is under the most stress rather than averaging it away. This can be changed under Overlays -> MFD -> Tyre wear rate metric (choices: Max, Average).
• Pace comparison now picks the right lap for each session type: last lap in races, best lap in qualifying and practice. Time Trial sessions get a dedicated 4-row layout (PB / SB / Rival / Last Lap) with deltas against your personal best.

---

Bug Fixes

• Fixed the dashboard connection error that could occur on first load -- v4.0.0 inadvertently flipped the connection transport order, causing a crash when binary telemetry packets were sent over the wrong channel.
• Fixed the driver view not correctly highlighting the reference driver row when switching to spectator mode.
• Fixed the tyre stint history chart in the overall race stats page showing a blank tab on initial load.

This is a major release centred on a brand-new in-game HUD overlay, a fully overhauled engineer view, time trial support, and a wave of dashboard and overlay improvements.

🗺️ Engineer View - Full Overhaul

• Live track map showing real-time driver positions on circuit maps for all F1 2023–2025 circuits. The map can be rotated, and a reference driver can be pinned (click the star next to any driver's name).
• Weather forecast graph - temperature and rain probability displayed as a timeline across the session.
• Column settings profiles - save, rename, and delete named column layouts that persist visibility, order, and sizing. The Default profile always shows everything.
• Tyre and brake temperatures now appear in the race table.
• Collapsible upper section - collapse the header row to a compact one-line summary when you need more table space.

---

🎮 New HUD Overlays

• HUD overlay (new) - an in-game-style overlay showing gear, RPM, ERS, fuel, speed, and current corner/straight name. Configurable scale, opacity, and UDP toggle.
• Circuit info overlay (new) - a dedicated strip showing lap progress, sector splits, and corner info. Corner labels now correctly show the name above and turn number below; unnamed corners show turn number only. Configure its scale and its length to your liking!
• Drag-to-resize - overlay windows can be resized by dragging their edges. The old UI scale sliders are removed.

⚠️ Heads up: Due to the resize overhaul, saved UI scale settings from previous versions will be reset. You'll need to resize your overlays once after upgrading. (Positions will remain intact from the previous version config)

---

⏱️ Time Trial Support

• Timing tower has a dedicated Time Trial mode with lap/sector data, rival info, and dynamic rival labeling.
• Lap timer overlay now works in Time Trial sessions (delta not yet supported in TT mode).

---

🏎️ Driver View Improvements

• Column configuration - show/hide and reorder columns via a new modal; preferences are saved in the browser.
• Visual telemetry bars for tyre wear, fuel, and ERS in the table.
• Minimal damage display option - show only front wing damage instead of the full breakdown.

---

⚙️ Settings & Config

• UDP action codes pane - the settings window now lists all configured UDP action code mappings with live updates.
• Pace comparison MFD page - a new overlay page breaking down your per-sector pace against the car immediately ahead and the car immediately behind, so you can see exactly where you're gaining or losing time.
• Minimal lap timer mode - stripped-back display showing only your current lap time, delta, and sector bars for the lap in progress. Great for drivers who want just the essentials on screen.
• Font customisation for track limits, air/track temperature, and fuel displays.
• Configurable bind address for all web servers (default 0.0.0.0), set from the launcher.

🌧️ Smarter Tyre Wear Predictions

The tyre wear extrapolator has been overhauled to give more accurate end-of-stint predictions in tricky conditions:

• Weather-aware — if the weather changes mid-stint (e.g. dry → wet), wear data from the wrong conditions is no longer mixed in, keeping predictions reliable through transitions.
• Sliding-window regression — predictions now react faster to changes in wear rate rather than averaging over the whole stint.
• Safety car resilience — laps run behind the safety car (where wear is artificially low) are filtered out so they don't skew the projection.

This feature is disabled by default and can be enabled in settings.

---

🐞 Bug Fixes

• Fixed the HUD toggle (show/hide all overlays) not working.
• Fixed use_cpu_acceleration not being detected, which could cause severe performance degradation.
• Fixed settings search returning stale results.

🔍 Diagnostic Data (for debugging only)

This release introduces detailed performance counters and latency metrics written to the app's log file. This data never leaves your machine - the app does not transmit it anywhere. It is only accessible if you choose to share your log file (e.g. when reporting a bug). If you're curious, you can inspect it yourself at debug.pitsngiggles.com.

🙏 Contributors

Thanks to @PettableCat for major contributions to this release - engineer view overhaul, driver view improvements, web server enhancements, HUD watchdog improvements, and more.

Pits n' Giggles v3.2.2

This is a small patch release fixing two macOS-specific issues with file handling that caused crashes or write failures when running the bundled app.

🐞 Bug Fixes

• macOS: Session save now works correctly — Saving session data to disk was failing silently on macOS because the app bundle's working directory is read-only. Saves now go to the correct writable location (~/Library/Application Support/pits_n_giggles).

• macOS: File open dialog now defaults to a sensible location — On macOS, the file picker was opening in a non-accessible directory, making it difficult to navigate to your files. It now defaults to the app's data folder on first use, and remembers the last directory you browsed to on subsequent opens.

No Windows or Linux users are affected by these changes.

🐞 Bug Fix – Pit Rejoin Position in Web Dashboards (Driver & Engineer Views)

A bug introduced in v3.2.0 caused the pit rejoin position to always display as NA in the web dashboards (both Driver and Engineer views). This issue has now been fixed.

Along with the fix, the pit rejoin prediction algorithm has been improved. The prediction now accounts for additional parameters, including:

• Time spent in the pit lane
• Pit stop duration
• Other timing factors affecting rejoin position

These improvements provide a more accurate prediction of where the car will rejoin the race after a pit stop.
