Hello,
This is for python projects.
Today, May 4th, urllib3 https://pypi.org/project/urllib3/#history has released a new major version 2.0.2 which breaks the extremely popular requests https://pypi.org/project/requests/ library.
The fix is to pin urllib3<2 to prevent the new major version from being installed (example https://gerrit.wikimedia.org/r/c/integration/config/+/915736/1/tox.ini).
