Good morning, it's Tuesday, October 13th, 2026, and this is your Django briefing.

The main signal today is maintenance over new features, with work focused on making the object-relational mapper cheaper, more correct, and easier to maintain.

First theme: ORM internals. Pull request 22141 reduces the cost of building many-to-many related managers by moving relation-only attributes to the class level and avoiding repeated database routing lookups for reverse foreign key managers. That's a direct performance win for code that touches related objects in…

Second theme: geographic and database compatibility. Pull request 22140 would allow the Make Line aggregate to accept ordering on PostGIS, matching capabilities available since PostGIS 2.2. For spatial developers, this means ordered line construction without raw SQL workarounds. Meanwhile pull request 22139, now…

Finally, two small reliability fixes. Pull request 22061, now merged, makes the unordered object list warning point to user code instead of Django internals when pagination goes through list views, admin, or the async paginator. And pull request 22143 tightens file-based sessions to enforce integer expiry times…
