Getting ready for conf season and focused on keeping people unblocked, reviewing where available. Oh, and a new independent mailroom operator!

Focus

More of the same. Unblocking via review.

Bottleneck

Review of #1950 workarounds & build pipeline. If our pipeline was more settled (and corepc were cut). then we'd have cut another release by now.

Focus
A shift from last week's priorities: wasabi dropped; Integrations priority is now remaining BTCPay Plugin reviews, if time allows, clearing the critical path items from #1950, bindings fixes, then upgrades. more reviews

Bottleneck
The remaining accumulated backlog is getting large, but getting some items out of the way depends on communication speeds; I'd like to get it out of the way before more items pop up.
