Release notes for the official Django releases. Each release note will tell you what’s new in each version, and will also describe any backwards-incompatible changes made in that version.
For those upgrading to a new version of Django, you will need to check all the backwards-incompatible changes and deprecated features for each ‘final’ release from the one after your current Django version, up to and including the new version.
Below are release notes through Django 4.0 and its patch releases. Newer versions of the documentation contain the release notes for any later releases.
Whenever a security issue is disclosed via Django’s security policies, appropriate release notes are now added to all affected release series.
Additionally, an archive of disclosed security issues is maintained.
