Wow, cool. It's a step for raising the minimum supported Python version to 3.12 and bringing the new features from 3.11 and 3.12?

[laipz8200]

@bowenliang123 I think the minimum supported Python version should be 3.11, at first.

[bowenliang123]

SGTM. So are you considering using 3.11 in the dockerfile?

[laipz8200]

I’d prefer to use 3.12 while keeping compatibility with 3.11, but it still needs some testing.

[bowenliang123]

Reasonable. Let's suggested to use Python 3.12 in docs for deployment and development, while maintaining support for 3.11 in tests.

The PR #10386 is raised to show the impacts of bumping the minimum version to 3.11.
