Looks like another boring release - which is a good thing!
Django has definitely matured to the point where it does not need major breaking changes every release. Now updating to the latest version is somewhat trival.
At this point I have projects that span 3 major release of Django without any significant breakage. That's my favorite feature.
I like the querystring feature. Before I write my own, does anything like this exist outside of Django for other Python-based projects? I use Flask, with jinja2 of course for templating.
I use Flask a lot too. I generally just add keyword arguments to url_for() to automatically add querystrings to URLs.
