+
+* **support:** Unity 2020.3 is no longer supported
+* **dotnet:** Removed all explicit/implicit operators to convert Algorand.Unity types to Algorand
+types. All conversions now can be done with `ToUnity` and `ToDotnet` extension methods by
+referencing the `Algorand.Unity.Net` assembly.
+* **sodium:** Unity 2020.3 is no longer supported
+* All `AlgoSdk` namespaces are now renamed to `Algorand.Unity`. A simple find and
+replace should fix it.
+* **account:** Obsolete methods in `Account` class relating to signing have been removed.
+* **blockchain:** Removed `RootTransaction`
+* **services:** Algod no longer has `GetProof` method
