0.88.0 is the latest version. Is there are reason not to update to that version?

Hi @sanders41 thanks for reviewing! No real reason other than that I've done a lot of testing of this version and no testing of the latest.

Seeing sqlalchemy.exc.TimeoutError: QueuePool limit of size 5 overflow 10 reached, connection timed out, timeout 30.00 (Background on this error at: https://sqlalche.me/e/14/3o7r) after bringing this up-to-date with main, this happened several times - will not be merging until I know what this is.

@pattisdr looks like 0.88.0 is also failing, but for different reasons #1863. The failures with 0.85.1 I'm not sure what is causing this.

I think I understand the failures in 0.88.0 and know how to fix them. The TestClient was changed from requests to httpx so the methods/arguments need to be updated for httpx.

Thanks for looking into this @sanders41 - yeah it might be best to upgrade all the way. I should have started testing that version first, I had just been looking at this version to see if it would resolve a bug we had on the plus side.

Closing - we should just update to 0.88.0 in #1863.
