 - SqlServerDsc.Common
   - Removed the function `Get-RegistryPropertyValue` and `Format-Path` in
     favor of the commands with the same names in the module _DscResource.Common_.
+- SqlRSSetup
+  - The DSC resource has been refactored into a class-based resource
+    - The parameter `SourcePath` was removed and replaced with `MediaPath`
+    - The parameter `IAcceptLicenseTerms` was removed and replaced with a
+      boolean parameter `AcceptLicenseTerms`
+    - The parameter `SourceCredential` was removed. Because of this the
+      functionality that allowed copying the media from a UNC path using
+      those credentials was also removed. If this was something you used,
+      please open an issue.
+    - The version validation no longer gets the current version from the
+      installed package (using `Get-Package`), but instead from the registry.
+    - The read-only property `CurrentVersion` was removed and replaced with
+      the more appropriate property `ProductVersion`.
+    - Prior when install was successful the resource checked whether there
+      were any pending rename operations. Since the install returns 3010
+      if a restart is needed it is now assumed that the setup process takes
+      care of this. If that is not the case, and this check is needed, then
+      open an issue to discuss in what cases this is needed.
