 ## Update history
 
+### 3.2.0
+
+Added support for HMACSHA256 and HMACSHA512 as per the [RFC spec](https://datatracker.ietf.org/doc/html/rfc6238#section-1.2). In testing it was found that several popular apps (such as Authy and Microsoft Authenticator) may not have support for these algorithms so care should be taken by the developer to ensure compatible apps are used.
+
 ### 3.1.1
+
 Fixed an edge case where specifying an interval of 30 seconds to the Validate function would be treated as if you had passed in 0.
 
 ### 3.1.0
 
+- Removed .NET 5 and added .NET 7 to test frameworks
+- Updated dependencies for test runs
+- Support ValidateTwoFactorPIN with iterationOffset as parameter
+
 ### 3.0.0
 
 - Removed support for legacy .Net Framework. Lowest supported versions are now netstandard2.0 and .Net 4.6.2.
