 ## Recent Changes
 
+## `2.10.0`
+- Bugfix: Datasets with VOLSER set to an MVS Symbol would cause dataset read, write, and metadata API calls to fail for those datasets. (#603)
+- Bugfix:  Preventing error code 0C9-09 caused by a block size of zero (#606)
+
 ## `2.9.0`
 - Bugfix: expose the version of the ZIS dynamic linkage base plugin so it can be updated during a build
 - Disable the ZIS dynamic linkage plugin as it's not needed by default
