New Features

  • 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)

Bug Fixes

  • Fixed a bug where incorrect positions were calculated for all drivers at the end of the first lap in the 2025 British GP (#765)
