• New League Rules with No Refuelling, Two-tyre rules and more, available now as editable options for the league host. Further reading: League Rules guide
• Improved dirty air and slipstreaming physics for closer racing.
• Until further notice, driver weight will not impact the simulation, also for closer racing.
• Improved qualifying: push level now unaffected by advanced strategy and uses more precise fuel loads, benefitting fuel economy development.
• Improved accuracy of connection instability prompts, they were showing too frequently.
• Improved UI consistency of team management screens across various devices and pixel densities.
• Improved league finder and league page to show key information on league and race settings and rules.
• Fixed a bug when go to pits action was not properly sent.
• Fixed an Android ANR (app not responding) problem by updating SDKs.
• Fixed a rare bug when the WebGL race viewer was very low-res on launch.
• Fixed visual inaccuracies in 2D race viewer masks for overhead objects (bridges, trees etc.) causing cars to appear and disappear in the wrong locations
• Fixed pressing ESC in WebGL resulting in the camera pointing at nothing with all cars disappearing.
• Fixed a glitch that resulted in deselecting the car in 3D and the camera becoming stuck.
• Fixed a bug where a driver name was not properly updated on the timing row.
• Fixed a bug where a translation could fail to load on management screens if there was a corrupt translation file.
• Fixed UI scaling bug introduced by Samsung One UI and/or Android System WebView updates.
• Implemented new 'Disqualified' status for drivers in live timing and race results.
• Fixed bug with sponsor 1 showing in slot 2.
• Upgraded several SDK integrations.

• Changes to 'dirty air', allowing cars to follow more closely and overtake without DRS.
• Subtle changes to Push Level, Boost, DRS and Fuel load to make their impacts more noticeable.
• Nerfed car attributes: Acceleration, Braking, Downforce and Handling. This is only a minor reduction intended to prevent cars reaching top speed as easily and to increase the effectiveness of DRS, further encouraging overtaking.
• Buffed car attributes: Fuel Efficiency and Tyre Efficiency.
• Tyres are more influenced by the climate / temperature such that different strategies can work in different seasons.
• Increased wear rate for Soft tyres.
• Decreased wear rate for Super Soft and Hard tyres.
• Changes to the tyre wear rate curve, making it more linear.
• Increased pace for Super Soft and Hard tyres.
• Decreased pace for Soft tyres.

These changes to racing have been developed with a team of high level managers based on their feedback. This update does not require any updates to be downloaded. It will be seamlessly implemented in to future races after this changelog.

NOTE: Races that took place on 11 December from 11:30 UTC to 13:00 UTC ran on a different balance to races after 13:00. Since 13:30 the Super Soft tyre performance has been reduced slightly.

Patches 4.051 and 4.052 are hotfix patches for 4.050, which were released in quick succession, containing several fast but important fixes. At the time of this changelog entry they are available on Android and Windows standalone and pending approval for release on iOS. UPDATE: Patch 4.051 is available on iOS as of 27 Nov @ 17:00 GMT.

4.051

• Fixed 2D having offset racing lines on re-scaled tracks.
• Fixed boost tail missing in 2D.
• Fixed commentary text being invisible.
• Fixed misaligned track alpha masks in 2D.
• Fixed Driver/Team column toggle on live timing table not working on landscape layout.
• Fixed a bug when viewer settings were not properly applied between races.
• Fixed 3D water splash effect having a missing texture.
• Fixed Windows standalone not launching on some devices (reinstall may be required if experiencing this issue).

4.052

• Fixed the currently selected driver's DRS indicator in overhead telemetry not lighting up in the 3D viewer interface.
• Further fixes and improvements to 2D viewer alpha masks that hide cars under overhead objects (bridges etc.).
• Fixed 2D boost effect displaying as larger than the car.
• Fixed misaligned driver health and tyre condition gauges, noticeable when a driver has retired or the race is over.
• Fixed sector "bars" on live timing only reporting the sectors when the viewer was launched.
