This is a major change, probably changing some packet version underneath, probably gcc-arm-none-eabi and clang which can impact some projects.
Doing this should be done carefully.

Looking at the build logs, alpine 15 installs:

clang (12.0.1-r1)
gcc-arm-none-eabi (10.3.0-r0)

And alpine 16 installs:

clang (13.0.1-r1)
gcc-arm-none-eabi (11.2.0-r2)
