Finally, Real-Time Django Is Here: Get Started with Django Channels

Django Channel header

Today, we're thrilled to host Jacob Kaplan-Moss. Jacob's a former Herokai and long-time core contributor to Django, and he's here to share an in-depth look at something that he believes will define the future of the framework.

Today we are introducing Add-on Controls for Heroku Enterprise customers. This new feature enables team leads to whitelist specific add-ons for approved use within their organization, choosing from our marketplace of over 150 add-on services.
