• 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.

• Rescaled circuits - Belgium, China, Malaysia, Mexico and Singapore have all been re-scaled to have a normal road width and circuit length. Number of laps (100% length):
  Belgium 43 Malaysia 55 China 55 Singapore 60 Mexico 70
• Improved visual accuracy in races - The visual position of cars on the track in both 2D and 3D modes has been substantially improved to reduce out-of-sync events creating visual gaps inconsistent with live timing.
• New TV Cameras - Ideal for streaming, broadcasting and recording race videos, or for increased immersion for managers who want to participate in a race like it's on TV.
• Performance & Stability update (part 2) - Parts 1 and "1.5" of this update increased app stability for everyone in the managerial screens only. This update builds on those improvements to further stabilise app launch and runtime performance, plus improved reliability and performance when loading, viewing and returning from live races.
• Greatly improved 3D Visuals - major revisions to all surfaces such as terrains, asphalts, gravel traps. Higher quality textures, the elimination of visible texture tiling through shader techniques.
• Fixes to race viewer loading - reducing scenarios where viewer loading could get stuck.
• Fixes to app launch - reducing scenarios where the app could cease responding or crash on low-end devices.
• Fixed Android push notifications not sending.
• Various other fixes and improvements.
