Quart on the new flask 3.1.0 release, and PROVIDE_AUTOMATIC_OPTIONS

[afurgal]

Was pulling my hair out today to track down a new error on quart / hypercorn related to PROVIDE_AUTOMATIC_OPTIONS.

Managed to track it down to the recent 3.1.0 release of flask, and @pgjones looks like you fixed but have not released this already. 2473a04

I'm new to quart so be kind, and probably have missed a lot of crossover an nuance.

This was my stack trace, and have fixed now by putting flask==3.0.3 before quart in my package installs. Are there any other workarounds which might be a bit more elegant, or different ways to configure options?

It was a temporary incompatibility with Flask 3.1. The release fixing this is literally being built and uploaded right now.

Quart 0.19.9 is now available on PyPI.
