WTForms==3.1.0 is fixed in providers-constraints: https://raw.githubusercontent.com/apache/airflow/constraints-main/constraints-source-providers-3.8.txt
Which I believe is failing CI image building on my local Breeze installation:

Shouldn't the constraint file be changed to reflect WTForms<3.1.0 version dependency? Or is it some problem on my local installation?

@potiuk tag you just in case

ABR - Always Be Rebased.

This limit has been removed few days later as FAB fixed the problem and we upgraded to latest version of FAB (FAB version is pinned in Airflow).

You are not living on the "edge enough".
