Troubleshooting improvements

You can now get to troubleshooting easier than before, press Shift+T in the main window, and you will be taken to the troubleshooting page. You can also get to the troubleshooting page by clicking the "Troubleshooting" button in the sidebar.

And, if you're asked to provide a screenshot, you can now press S to take a screenshot and it's copied to your clipboard. You can then paste it into Discord.

Other changes:

• You can now open settings by pressing Cmd/Ctrl+, in the main window

• Holding the Alt/Option/Ctrl key while using the Switch stream option in the right-click menu, it will open the stream in a new player

• You can step through the tutorial with arrow keys

• Add little hint that ESC toggles the live timing settings bar at the top

Onboarding improvements

The app now greets you with a short tutorial and a pre-check, to ease the onboarding process. The pre-check checks for a number of common issues and will tell warn you if there are issues. The tutorial will guide you through the most important features of the app.

Other changes:

• Fixed a bug where team radios would show "An error occurred"

Changes:

• Improves live timing sync by using the live-timing latency and correcting for it
• Adds two new settings as a "escape hatch" in case the new corrections don't work as intended (I'll keep people up to date in Discord)

Changes:

• Fix track map (position) and car telemetry
• Hopefully fix the live timing sync

Improved live sync

Live sync had a number of issues for people, mainly that the live timing sync didn't work at all. This release is supposed to fix that, but it's impossible to test that without a live session. If you experience issues, please check your "Default base latency" in settings (if you didn't touch it, it's 30s by default), and calculate the "correct" live timing delay: live timing delay = (default base latency in ms, so 30000 by default) + 15500. You'll need this in case the new algorithm doesn't work for you. On Discord, we have a #syncing channel that you can read updates and instructions.

Other changes:

• Troubleshooting now also checks if you have "play from start" turned on
• Improved error messages with status code and body

Changes:

• Fix layout schema validation
• Add link to troubleshooting in the app menu

Troubleshooting

MultiViewer for F1 now has a "Troubleshooting page", accessible from the sidebar. This page is basically a health-check and checks all kinds of common issues and shows you how to fix them. If you have any issues, please check this page first and see if it helps you. If not, you can reach out on Discord and we'll try to help you out.

GraphQL API

MultiViewer for F1 now has a GraphQL API, which is available at http://localhost:10101/api/graphql (or check Settings, your installation might be using a different port). This API is currently in beta and is subject to change. If you have any feedback, please reach out on Discord.

Team Radio

You can now view and listen to select team radio captures (the same that were available in the F1 mobile app). If you don't want to see them, you can disable it in Settings. See how it works

Other changes:

• When clicking on the speed in the driver telemetry bar, it'll now open detailed speed trap information
• Changes to how gaps are shown
  • If the driver is within 1s and it's a (sprint) race session, the gap will have a green background
  • If the driver is marked as "catching" (meaning that over the last few laps, the driver has been gaining time on the driver in front), the gap will have a green border
• Config and layouts now reside in the correct folder (instead of directly in %AppData% on Windows, and Application Support on macOS)
• Speed up initial boot by not loading developer extensions in production
• Add 360p and 240p presets to "Set size" in the player context menu
• When turning off driver telemetry, the DRS will remain visible
• Fix possible (slow) memory leak in live timing

Fixed since the beta builds:

• Add GraphQL explorer
• Fix country detection

Live sync

Live sync is now available by default, and a number of improvements have been made. Live sync now also attempts to sync the live-timing (this is considered experimental), and now works from any player, not just from international. Feedback is still appreciated.

Moar data = Moar better

You can now view leaderboards for speeds on speed traps and best sector times by using the new buttons next to the weather in live-timing.

Championship predictions

That's how they're called anyway, but it's more like "live championship points", where you can see what the standings would be like were the session to finish right now. This is only available in sessions where points are awarded, not during qualifying (except sprint-qualifying) or practice.

Other changes:

• Hide car telemetry: if you don't use car telemetry, or want to preserve your CPU/GPU, you can now hide it.
• Close all other players is now an option in the context menu
• Live in schedule: Schedule now uses items from the homepage to show them as live, instead of just scheduled start time
• Players will now prefer cloudfront CDN, which is more reliable, and only fall back if that fails
• Wind direction simplified, limited to 8 directions, no longer 3-character
• Warning is now shown when "play from start" is enabled, since various features are unavailable and people may have it left enabled
• Switch stream context menu now has consistent sorting
• ChampionshipPrediction topic is now available in the API

Changes:

• Add recovery vehicle RCM detection
• Make sure safety-car related penalties/investigations don't get the safety-car icon
• When dates are unavailable in schedules, events will be sorted using their "session index", ensuring they are still in logical order (for older seasons)
• Update Electron to 21.2.0

Experimental live sync

There's now a very experimental live sync method available. To enable it, open Settings, scroll all the way down to "Experimental settings" and enable "Live sync". This method will try to see the differences in the live latencies across players and correct for it. This may not work, and may screw with your sync, which is why it's disabled by default. Try at your own risk, and please report any issues you may have with it using this form

Other changes:

• Refactor cross-window player communication
• Add live-latency diff tracking (for use with live-sync)
• Add live-content error dialog (for people in regions without F1TV Pro)

Changes:

• Fixed auto-update mechanism for multi-platform builds

Changes:

• Fixes a DRM issue on macOS (please note there are now separate builds, if you're on a M1 or M2 Mac, you want to get the "Apple Silicon" or arm64 build, if you're on an Intel Mac, you want to get "Intel" or x64)
• Added test tire compound (note that the test compound is only identified as such later in the FP2 session, it starts out as unknown)
