It contains some changes, new features and patches also.
If you used the HEOS binding before, so you already have your HEOS Things, you should delete them and recreate to see the new channels.
In my opinion the usage of the binding is more straighforward and in my tests, it works as it should. However, again if you already use the binding, be prepared that some channels changed/removed so not everything will work as it was before.
