FSD Software Changelog

Tesla began rolling out FSD (Supervised) v14.3.3 inside firmware 2026.14.6.6 on 17 May 2026. The release adds a live intervention-free streak counter in the Self-Driving App, unifies the Actually Smart Summon backend with FSD and Robotaxi for a max-speed bump from 6 to 8 mph, and bundles the full 2026 Spring Update payload for both HW3 and HW4 vehicles.

Tesla pushed FSD v14.3.2 firmware 2026.2.9.9 to a wider rollout in late April 2026 with a redesigned post-disengagement menu adding a 'Navigation' option, and a new seat belt rule that lets drivers unbuckle before parking is engaged. Fleet saturation reached around 15 percent within 24 hours.

Software build 2026.2.9.8 collapses three previously separate Tesla AI stacks into one unified model, improving Actually Smart Summon behaviour and adding Blind Spot Warning While Parked. EU cars receive the update without Supervised FSD activation.
