Happy to help with this release. Unless someone else starts the work I'll try to put up some PRs this week.

Thanks @mbrobbel 🙏

I think the biggest thing that would help is to look through any open PRs that are stuck / haven't been reviewed and identify any that we should try and get in.

I don't have any from my side that need to get in

[alamb]

I will plan to test downstream with DataFusion

a bit last minute, but would love to get #8363 in to unblock work downstream in DataFusion.

Merged!

I think this is shaping up to be a good release
