v0.3.4 2026-07-16

Fixed

Le Mans Ultimate: RacePulse now works on fresh LMU installs with zero setup. It reads the shared memory interface built into the game, so the rF2 Shared Memory Map plugin DLL is no longer required — just turn on Settings > Gameplay > Enable Plugins. Previously, LMU telemetry silently depended on a plugin that other apps (Crew Chief, wheel software) happened to install; without it, RacePulse never detected the game. Older LMU versions that predate the built-in interface still fall back to the plugin if installed.

Improved

Le Mans Ultimate: your car is now identified directly by the game instead of through name-matching heuristics
In-app Help and the website setup guides for LMU rewritten for the zero-setup flow

v0.3.3 2026-07-16

Added

Widgets can now be hidden and shown again without losing them — hiding previously closed the widget for good
Smarter delta timing: the reference lap is now selected automatically and new personal bests are promoted as you set them

Fixed

iRacing: tire pressures now show real PSI values (a unit conversion ran the wrong way, giving readings in the thousands)
iRacing: on-track detection works again — it was permanently “off track”, which kept dependent widgets dark
iRacing: shift lights now scale to each car’s actual redline instead of a fixed RPM
iRacing: checkered and cooldown phases are no longer swapped at the end of a race, and wind speed uses the correct unit
iRacing: the last driver in the session roster is no longer missing from the leaderboard
iRacing: leaderboard gaps to the leader are now accurate
ACC: shift lights work again (a data type mismatch left them permanently dark)
ACC: the clutch bar no longer reads 100% while driving — the sim reports clutch engagement, which is now converted to pedal position
ACC & AC: pausing the game no longer disconnects the session after a few seconds
ACC: the live delta now works from your second lap onward
ACC: all three sector times now populate correctly
ACC: your car now appears at its true position on track maps
Assetto Corsa: flags and pit-lane detection now work (the app was reading ACC’s memory layout, which AC doesn’t share)
Assetto Corsa: phantom cars no longer appear on track maps
Le Mans Ultimate: tire temperatures now display in Celsius instead of raw Kelvin (~350°)
Le Mans Ultimate: track flags and session types now map correctly — green-flag racing no longer shows as a caution, and races are no longer “unknown” sessions
Le Mans Ultimate: the delta no longer compares against sectors you haven’t finished driving
Le Mans Ultimate: torn shared-memory frames are discarded instead of producing corrupted readings, and shared-memory faults no longer stop capture
F1 24/25: F1 24 is now auto-detected (a port bug made it undetectable on a fresh start)
F1 24/25: driver names are no longer garbled in F1 25, and several packet layouts were corrected for both games
ACC, AC & LMU: the rev limiter indicator no longer flashes before the car’s redline is known
Widget layouts can no longer be corrupted by a crash during save — saves are atomic, and a damaged file is set aside and recovered from instead of silently overwritten
Launching RacePulse twice no longer cross-wires widgets between the two instances
Widgets automatically reconnect if their connection to the main app drops
The app can no longer hang forever on exit — shutdown is bounded
Failed auto-connects now back off progressively instead of retrying every 3 seconds
Fuel-per-lap estimates are no longer skewed by your first lap out of the pits
Track map no longer shows a bogus gap to the car ahead while crossing the start/finish line
Invalid values from the sims no longer cause telemetry frames to silently drop
The inputs graph no longer floods solid red in widget previews
Rapidly toggling widgets on the Home page no longer gets them stuck

Improved

Live widget previews are far more realistic: coherent lap times, ticking sectors, a true live delta, distance-accurate car movement on the track map, and a proper multiclass field — with no flickering lap times
Lap time, delta, and gaps on ACC now update smoothly instead of stepping a few times per second
The Help menu now explains that ACC and AC can only be detected once you’ve loaded into a session

v0.3.2 2026-07-02

Added

Widgets, previews, and pages now show a small error panel instead of going blank if something unexpected goes wrong

Fixed

iRacing: projected iRating now reads the correct field and only shows in valid sessions
Le Mans Ultimate no longer gets stuck in a detect/reconnect loop after the game closes and its shared memory goes stale
F1: reconnecting now works after capture stops on its own (the UDP port is released properly)
Fixed hangs that could occur when stopping telemetry capture on iRacing, Le Mans Ultimate, and F1
Assetto Corsa Competizione and Assetto Corsa no longer hang when the game closes on its own
Failed auto-connects now retry and surface the error instead of failing silently
Telemetry no longer bleeds between sessions when switching games

Improved

Major performance pass while driving: the Home and dashboard pages stop re-rendering at 60Hz during capture, off-screen widget previews pause, graph canvases only reallocate when resized, and analysis and track-map updates are throttled — noticeably lower CPU and GPU usage
Home quick links restyled into a single row

v0.3.1 2026-06-02

Added

Help menu in the app header with quick-start steps and per-sim setup instructions (F1 UDP port, Le Mans Ultimate plugin, and more)

Fixed

Header tooltips no longer get cut off at the top edge of the window — they now open downward

Improved

Redesigned the main app header into a single unified control bar — game detection, connection status, and connect/disconnect now live in one cohesive control instead of separate status badges and buttons
Edit Mode and Click-Through are now clearly labeled toggle switches, so it’s obvious what they control and whether they’re currently on
The widget on/off switch is now screen-reader accessible and shows a brief spinner while a widget starts up or closes (and ignores accidental double-clicks)
Restyled the “reset to default settings” confirmation dialog to match the rest of the app

v0.3.0 2026-05-01

Fixed

Mid-session crashes during long Le Mans Ultimate races — several edge cases that could take the app down are now caught and contained
A single slow widget can no longer freeze every other widget on screen
Telemetry no longer cuts out for a moment during loading screens and session transitions
F1 telemetry handles unexpected or partial UDP packets without crashing
Rare crashes when closing the application
Pit window warning now correctly fires when your fuel tank reaches empty
Negative fuel readings from sensor glitches no longer break the fuel display
Personal best laps are now correctly marked in the lap list and session export
Lap consistency stat is now accurate (it was slightly too generous before, especially with only a few laps recorded)
Leaderboard rows no longer flicker when two cars share the same position
Leaderboard gap to the car ahead is now calculated correctly in all cases
Track map widgets handle missing track data on loading screens — cars no longer fly off to “infinity”
Le Mans Ultimate: only your car is now identified as the player car (some sessions previously flagged multiple cars)
Cars sitting exactly on the start/finish line stay visible on the Flat Track Map widget
Fuel widget’s low-fuel red color now triggers at the right moment when remaining laps include a decimal
Overlay opacity slider can no longer be broken by an invalid value (which previously made every widget invisible)

Improved

The auto-updater now only installs stable releases and skips beta/draft versions
Better error messages when an update fails to download (you’ll see what actually went wrong instead of a confusing “checksum mismatch”)

Compatibility

Existing widget layouts and per-widget settings carry over from earlier versions — no reconfiguration needed
