 ## What's New in 3.2?
 
-- Async - write more here!!!!
+- A lot of backend rework of the integration to utilise built in HA functions and make it more performant.
+  - Moved to a new fully async api from the old sync api
+  - Now utilises the data update coordinator functionality in HA instead of our own custom one
+  - Quite a bit of code tidying and black formatting
+
+- MORE TO COME BEFORE RELEASE - ADD HERE!
