Would be great to talk about a timeline for the next Esplora client release. In particular, LDK Lite would make use of a recently merged PR. It would therefore would be nice if the upcoming BDK release (that will hopefully also finally include an update to rust-bitcoin), would include the updated Esplora client already.

[notmandatory]

The hold-up right now for upgrading BDK to rust-bitcoin 0.29 is that we also need the rust-miniscript crate updated, and I haven't seen an ETA yet on that (https://github.com/rust-bitcoin/rust-miniscript/milestone/1?closed=1). But we should still be able to do a release of the Esplora client. I'll add it to the agenda to discuss on Tuesday. And maybe we can also add a feature flag or something like that to use rust-bitcoin 0.29 instead of 0.28 in the esplora client.

Yeah, I've been monitoring the progress in rust-miniscript. It's not entirely urgent, but it would be nice to have a BDK release with rust-bitcoin 0.29, especially since there will be a pause before the migration to BDK core, IIUC?

The main pain point for me is that LDK updated rust-bitcoin basically immediately and since this conflicts with BDK, I can't make use of any upstream changes I got merged into LDK since then, even though we had at least one release in the mean time...

[notmandatory]

For bdk we'll keep making dependency updates and bug fixes on the same monthly schedule, but we just are not doing any big feature changes until the bdk_core PRs are merged. So as soon as rust-miniscript is updated we can upgrade the rust-bitcoin version too.

Ah, that's good news! I so far thought there would be one last release before the big one.

[notmandatory]

Yes, and if necessary we can keep back-porting fixes to what ever the final pre-1.0 version is to give users time to update to 1.0.

rust-miniscript had a release just a few hours ago 🎉

I fixed the week # on this.. I had 45, but should be week 43.
