Django Fellow Report - Jacob - 2025

Django Internals
11

Week ending 2025-11-09 (Week 45)

This week we landed a migrations fix that prevents flaky CircularDependencyErrors when squashed replacements are in play. If you haven’t tried squashing migrations in a while, check out main and give it another go!

We also fixed an unreleased regression in the urlize template filter–big thanks to Mehraz Hossain Rumman for testing the beta. (Are you the next tester to report a regression before 6.0 final?)
