As a long time Django and DRF user I'm really happy this release finally got out. If you look at the PRs being released some of them are years old. It's true that DRF is a mature and feature-complete framework but Django is still evolving slowly and DRF must keep up with that at the very minimum. Big thanks to the maintainers for getting it out!

Here are some of my hilights from this relase:

* Default on model gets sent to API docs

* Orderedict replaced by plain dicts everywhere - plain dicts are ordered in python since 3.6 so this is a welcome simplification

* Automatic support for UniqueConstraints in ModelSerializers - this is one of the places where DRF were lagging behind. I found myself using the deprecated unique_together just to not bother with writing validators on all my serializers

* There is a new router supporting path converters instead of regexp - Looking forward to trying this out! Also long overdue IMO as this came to Django in 2017 :)
