What’s new in v3.6.1¶

(released 05/09/2025)

Fix an error when generating the driver-team mapping for plotting constants (caused by incorrect source data in the 2025 Monza FP1).

(released 08/07/2025)

The number of laps that each driver completed in a race or sprint session is now available in SessionResults, accessible through results, in a new Laps column. (#766)
fastf1.get_events_remaining() now correctly considers the current time of day and the starting time of the last session of an event to determine the remaining events. (#750) (by @VLADOZXD)
Preliminary Race and Sprint results are now calculated from timing data when no official results data is available from Jolpica-F1. (#737) (by @Casper-Guo)

Fixed a bug where incorrect positions were calculated for all drivers at the end of the first lap in the 2025 British GP (#765)
Added additional logic to detect and correct incorrect tyre information in the source data of the 2025 Australian GP Race and the 2025 Miami GP Sprint (#746)
The API parser will now calculate missing lap times from existing sector times if possible when the source data explicitly indicates a missing lap time by providing an empty lap time object. This fixes data errors caused by transponder issues with RUS car at the 2025 Bahrain GP. (#740)
The team name matching used with the plotting functionality now additionally considers the team short names to fix problems with the short “RB F1 Team” name. (#726) (by @Casper-Guo)

The following module level properties of fastf1.plotting have been removed: COMPOUND_COLORS DRIVER_COLORS DRIVER_TRANSLATE TEAM_COLORS TEAM_TRANSLATE COLOR_PALETTE

The argument misc_mpl_mods of function setup_mpl() has been removed without replacement for its functionality.

Addressed upcoming changes in pandas and fixed a related deprecation warning caused by implicit type coercion. (by @Casper-Guo) (#727)
