Hi Jason,
I've been keeping my pi current, both on OS and BAP updates, so there should be no mismatches. I'm still on Buster. The last date on any file in the .wl2k-old file was Nov 5, 2021, so that's when things changed (IE. I did an apt update/upgrade and ran BAP update). I've run updates since then too.
