@@ -3,6 +3,7 @@
 ## 12.8.0-beta.2 (Unreleased)
 - Fixed bug where the Stream returned by BlobBaseClient.OpenRead() would return a different Length after calls to Seek().
 - Fixed bug where BlobBaseClient.Exists() did not function correctly for blob encrypted with Customer Provided Key or Encryption Scope.
+- Added support for AzureSasCredential. That allows SAS rotation for long living clients.
 
 ## 12.8.0-beta.1 (2020-12-07)
 - Added support for service version 2020-04-08.
