What's new in Django 2.0?

Simplified URL routing syntax

The new django.urls.path() function allows a simpler, more readable URL routing syntax.

For example, this routing from previous Django releases:

url(r'^articles/(?P<year>[0-9]{4})/$', views.year_archive),

can be written as:

path('articles/<int:year>/', views.year_archive),

Mobile friendly contrib.admin

The build-in admin dashboard of Django is now responsive and supports all major mobile devices.

This is super useful, when you need to update some of your models in your live app, but your are on the go.

Window expressions

The new Window expression allows adding an OVER clause to your querysets and also do "magic" like the following:

from django.db.models import Avg, F, Window
from django.db.models.functions import ExtractYear

Movie.objects.annotate(
    avg_rating=Window(
        expression=Avg('rating'),
        partition_by=[F('studio'), F('genre')],
        order_by=ExtractYear('released').asc(),
    ),
)

🙌 Django 2.0 is the first release to drop support for Python 2 (works exclusively on Python 3) and is the last release to support Python 3.4.
