Not at this time. I'm pretty full up at this point with day job ( https://replay.io ), conferences, and personal life stuff.
My current ongoing Redux maintenance task is trying to revamp our "Redux Essentials" tutorial to be TS-first. Making slower progress on that than I'd wanted, but hopefully can get that wrapped up in the not _too_ distant future.
Beyond that, we've got a ton of open RTK Query feature requests that I'd like to address later on this year.
