New dual-branch firmware
Firmware 2026.27.11 is the current public dual-branch NA build. HW4 stays on FSD (Supervised) v14.3.10. HW3 Model 3 / Y stay on FSD (Supervised) v14.2 Lite — Tesla did not publish a new Lite number. Not a Tesla App says this is an updated FSD release from 2026.27.10 with the same version numbers and the same public notes. Teslascope is logging both computers onto 2026.27.11 in North America today. Still Supervised. No v15.

v14.3.10 on HW4 — same notes as v14.3.9
Firmware 2026.27.10 is an early North America HW4 wave. Cars are logging FSD (Supervised) v14.3.10. Tesla published the same FSD notes as v14.3.9, including Automatic Collision Evasion. Not a Tesla App says the extra on this build is Vehicle-to-Home with Powerwall on Cybertruck, not a new FSD feature list. Confirm the version on the car. 2026.27.6 remains the public dual-branch (HW4 v14.3.9 / HW3 v14.2 Lite). HW3 Lite number did not move. Still Supervised.

New dual-branch firmware
Firmware 2026.27.6 is the public dual-branch NA build. HW4 moves to FSD (Supervised) v14.3.9 with Automatic Collision Evasion. HW3 Model 3 / Y get the same firmware with FSD (Supervised) v14.2 Lite — Tesla published a new Lite version number. Early North America wave; 2026.26.6.5 remains the larger install. Still Supervised.

v14.3.9 on HW4 — Automatic Collision Evasion
HW4 S / 3 / X / Y / Cybertruck get v14.3.9. Automatic Collision Evasion can engage FSD (Supervised) during manual driving if a frontal collision is imminent and braking alone may not avoid it, or if the car detects insufficient attention or an unintended disengage. Tesla published the same core notes as the employee 2026.27.5 build. Confirm the version on the car. Still Supervised.

v14.3.9 adds Automatic Collision Evasion
Firmware 2026.27.5, HW4 only. Automatic Collision Evasion turns FSD (Supervised) on while you are driving manually, in exactly two cases. One: a frontal collision is imminent and braking alone may not avoid it. Two: the car detects you are not sufficiently attentive to the road, or that FSD (Supervised) may have been unintentionally disengaged. Still Supervised — Tesla's own notes say it does not make your vehicle autonomous. Employee release for now: 0 cars on the build. HW3 Model 3 / Y stay on v14.1 Lite (2026.26.6.5) and do not get v14.3.9.

Firmware 2026.21.6 ships FSD (Supervised) v14.1 Lite to HW3 Model 3 and Y. Public notes match earlier Lite — distilled HW4 v14 behavior, parking/unparking, Arrival Options, Speed Profiles. Aimed at stability and ECU thermal issues after early August overheating reports on prior Lite builds (APP_w141). Still Supervised. Same firmware serves HW4 as v14.3.7. Later waves expanded beyond the first NA cohort, including South Korea reports.

Tesla started a very limited rollout of FSD (Supervised) v14.3.7 on firmware 2026.21.5. Release notes match v14.3.6 — a maintenance build, not a feature drop. Keeps the unified Summon / FSD / Robotaxi model and Actually Smart Summon on Cybertruck.
