@maxirmx JFYI, CI is now broken due to Botan head issue. I'm fixing it via the PR #2240

Thank you I struggling with python upgrade on MacOs/ I guess it is something different

lgtm.

There is still https://github.com/rnpgp/rnp/blame/main/src/lib/types.h#L75

I guess one needs to include the sexp.h header before the types.h header?

@ni4 , I think we shall merge it on top of #2240

[ni4]
