Thank. Nbd on timing; I think (correct me if I'm wrong) I can just attach the signature to the release, after the event.

Yes. Recently had a situation where I added signature signed with a wrong key to one release, was able to change it later.

Ready to squash and merge according to me. LMK.

LGTM

However, as this is the "final" release, it might be good to ship this release with deps with their latest versions, for example secp256k1. Which is now at v5 (2024-05-06), latest is v7.1 (2026-01-26).

As a general principle, not going to be doing updates to latest on deps since that could be all sorts of extra work, but worth checking this one specifically. Reading the secp release schedule, 0.7 was an API break, and 0.6 was mainly for MuSig. Won't update (though of course later developments of joinmarket here or elsewhere definitely would have to pay attention to it at some point).
