Update, August 19, 2026: The Holiday branch is 2025.44.25.x cabin/Toybox software. The FSD point-build that landed on some HW4 EAP cars the same week is Tesery’s v14.2.1.25 note. Later 2025.45.5 / v14.2.2 is a different firmware train.
In the second week of December 2025 Tesla started pushing the 2025 Holiday Update as software 2025.44.25.1 (then .3 / .5). In-car notes listed Tesla Photobooth (selfies in Park, filters, share to the Tesla app) and Dog Mode Live Activity on iPhone (cabin temperature; Premium Connectivity adds periodic cabin snapshots; Tesla App 4.51.5+). Not a Tesla App and Tesla Oracle logged the official notes. This is a holiday firmware package. It is not unsupervised FSD, and Photobooth is not a camera-safety upgrade.
Key facts
- Version: 2025.44.25.1 and point releases, mid-December 2025.
- Cabin items Tesla wrote down: Photobooth; Dog Mode Live Activity on iOS; plus the usual holiday Toybox / light-show / Grok-nav bits on the same notes list.
- Hardware caveat: Several items were listed for AMD Ryzen cars, not every Intel MCU.
- What this is not: A new FSD generation. FSD version numbers travel on their own track.
Holiday notes vs FSD notes
Owners often see both land the same night. Read the car: one card is Santa and Photobooth; another may be FSD (Supervised) v14.2.1.x. Tesery already split the FSD pairing onto its own URL. Charging Passport is an app year-in-review, not this OTA.
FAQ
Do I need Premium Connectivity for Dog Mode Live?
Tesla’s note: temperature Live Activity without it; cabin snapshots need Premium Connectivity.
Does Photobooth work while driving?
Notes say the car must be in Park.
Is this v14.2.2?
No. v14.2.2 rode 2025.45.5 about December 22.
For owners: install if you want Toybox. It does not change your duty to watch the road on FSD.
