+
+It's time for release 0.21 and it contains massive core improvements: replacement of our home grown HTTP stack with a standardized WSGI stack. This will improve performance, speed, security and make future development of advanced HTTP features a breeze.
+
+This work was driven by the amazing Josh Wright. His knowledge, high standards and drive for security has helped improve Home Assistant a lot ever since he started helping out. Hip hip hurray for Josh!
+
+Alright, time for the changes:

+### Breaking Changes
+
+ - Our work in the WSGI stack is not fully done yet. We still have a minor issues where retrieving the error log in the about screen can raise an encoding error
+ - The API used to incorrectly accept a JSON body with form-url-encoded headers. Our cURL examples on the website used to be wrong and have [been updated].
