+
+In order to continue to drive the project forward, I'm launching a Kickstarter campaign to help fund the development of a major new release - Django REST framework 3.
+
+## Project details
+
+This new release will allow us to comprehensively address some of the shortcomings of the framework, and will aim to include the following:
+
+* Faster, simpler and easier-to-use serializers.
+* An alternative admin-style interface for the browsable API.
+* Search and filtering controls made accessible in the browsable API.
+* Alternative API pagination styles.
+* Documentation around API versioning.
+* Triage of outstanding tickets.
+* Improving the ongoing quality and maintainability of the project.
+
+Full details are available now on the [project page](https://www.kickstarter.com/projects/tomchristie/django-rest-framework-3).
+
+If you're interested in helping make sustainable open source development a reality please [visit the Kickstarter page](https://www.kickstarter.com/projects/tomchristie/django-rest-framework-3) and consider funding the project.
+
+I can't wait to see where this takes us!
+
+Many thanks to everyone for your support so far,
+
+  Tom Christie :)
