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.
These notes are retained for historical purposes. If you are upgrading between formal Django releases, you don’t need to worry about these notes.
