Good morning. This is your Django development briefing for June 12th, 2026.
The biggest development this cycle is a major async performance improvement. Two related pull requests from Hiteshsai007 are implementing native async Redis caching methods. Currently, Django's Redis cache uses sync-to-async wrappers, which creates unnecessary thread overhead and prevents proper full-page caching in…
The second major theme is reliability fixes across Django's admin and authentication systems. Pull request 21065 fixed a subtle bug where permission-only authentication backends were incorrectly selected by the test client's force login method.
