Features
Gantry Race Control (by @23Kev)
A new race-control view for spectating and replay review on a spare screen.
- Incident review: Follow a live incident feed, jump the replay directly to an incident, and switch the camera to any driver from the standings.
- Race-long lap graph: Review trace, position, or gap history that keeps recording while Gantry is closed and survives an app restart.
- Flexible workspace: Resize the standings and incident panes, browse drivers beside the lap graph, and use standings columns that remain aligned at different window sizes.
- Reliable detection: Crash detection is more accurate, works while spectating, and avoids duplicate reports during sustained incidents or replay rewinds.
Delta Speed (by @CtrlAltDale)
See how much faster or slower you are right now than your session-best clean lap at the same point on track.
- Choose automatic, km/h, or mph units and optionally show the numeric difference.
- The colour display fades from neutral toward green when faster or red when slower.
- A clear empty state explains when a clean reference lap is still needed.
Standings and Session Bar Enhancements (by @toba-k, @Foribald, and @tariknz)
- Resizable standings: Scale the Standings widget from 50% to 200% to suit your display.
- More session information: Add fuel, last and best laps, top speed, manufacturer position, and class rank to Standings and Relative session bars.
- Richer class headers: Use compact Strength of Field values and optional per-manufacturer car counts.
- Practice estimates: Optionally display hypothetical iRating changes during online practice sessions.
Input and Layout Improvements (by @Foribald)
- ABS bar style: Show ABS activity as a highlighted fill beneath the brake trace, with the original overlay style still available.
- Clearer gear display: Larger speed and unit text improves readability at smaller widget sizes.
- Layout alignment markers: Edge midpoint indicators make it easier to centre and align widgets in edit mode.
Performance Optimizations (by @tariknz and @23Kev)
- Reduced unnecessary background processing and display updates across normal dashboards.
- Improved efficiency when several widgets or displays use the same session information.
- Kept hidden overlays from consuming unnecessary processing until they become visible again.
- Smoothed Track Map movement and restored fast, stable Blind Spot Monitor updates.
Bug Fixes
- Settings window recovery: The settings window is moved back onto a connected display when a monitor is unplugged or rearranged (by @CtrlAltDale).
- AI class headers: Standings now show useful class headers and driver counts in AI races, even when iRacing omits class names or ratings (by @tariknz).
- Stable standings layout: Car numbers no longer shift adjacent columns as the displayed driver changes (by @tariknz).
- Accurate manufacturer totals: Class-header manufacturer counts now use the full field instead of only the visible standings rows (by @tariknz).
- Fuel label sizing: The
AVG 10consumption label no longer wraps or collapses at larger font sizes (by @tariknz). - Country flag columns: Empty flag columns are hidden automatically in AI and offline sessions (by @tariknz).
- Settings spacing: Nested settings and session-bar reorder controls now have consistent alignment (by @tariknz).
- Offline reference laps: Clean laps can now power live-position gaps and delta displays in offline sessions where iRacing reports class ID 0 (by @CtrlAltDale).
- Team-race pit timing: Driver swaps during a pit stop no longer restart the pit timer and shorten the reported stop (by @CtrlAltDale).
- Replay responsiveness: Track maps, standings, relative timing, and lap-time displays continue updating during paused and slow-motion replays (by @tariknz).
- Reliable quitting: A stalled save can no longer leave the app running indefinitely after Quit is selected (by @tariknz).
- Input trace visibility: The brake trace remains visible when ABS highlighting is turned off (by @Foribald).
- Speed-unit preferences: The steering dial now respects the configured speed-unit layout (by @Foribald).
- Browser dashboards: Restored session data and the animated live preview on the website (by @CtrlAltDale and @tariknz).
- Development replay: The telemetry replay tool can launch correctly on Windows (by @CtrlAltDale).
- Development reliability: Automated tests are more stable on heavily loaded build machines (by @tariknz).
