what is next most stable FW after 21.00?

The question is obsolete.
If you are not in the beta program and/or have downloaded the former alpha versions, you can only install the latest, stable? version. This is currently still the 25.10.

Hi, i have offline about 10 different Fw some alpha and betas. So i can choose which one. Also i have disabled auto update.

Well then ...
I still have the alpha 24.78 on the clock and no longer intend to update.
New features are no longer added and the 24.78 behaves normally in battery consumption.
In addition, BT headphones can be connected again. (Bugs in 24.76 or 24.77).
This version is sufficiently stable for me, although not without bugs. That e.g. nm are displayed instead of km (fixed imho in 24.79) does not bother me.
The only real innovation is the HRV status which was added in alpha 22.76.

so i decided to go 24.80, will see if its any good, dont fancy downgrading again...this is my collection if anybody wants old FW

I would like the 24.80 FW. I have a F6X pro that was replaced by garmin after it was bricked after the 25.00 update. Currently running 22.50 with no issues.
