I'm opening this here as the change will be applied here and affect all nRF24 repos.

I just noticed clang-format-12 is no longer available in apt PPA anymore (on Ubuntu).

sudo apt list clang-format*
Listing... Done
clang-format-13/mantic 1:13.0.1-13 amd64
clang-format-14/mantic 1:14.0.6-16 amd64
clang-format-15/mantic 1:15.0.7-10 amd64
clang-format-16/mantic 1:16.0.6-15 amd64
clang-format-17/mantic 1:17.0.2-1~exp1ubuntu2.1 amd64
clang-format/mantic 1:16.0-57 amd64

Looks like v16 is the default. Also, currently MSVC expects v16 or newer, so nRF24 devs running from Windows as their everyday OS can use the same clang tools required by other (up-to-date) projects that build on Windows.
