 ## Unreleased
 
+## 4.5.0.0
+
+- Opt-in to Example publishing to PowerShell Gallery - fixes [Issue #186](https://github.com/PowerShell/StorageDsc/issues/186).
+- DiskAccessPath:
+  - Updated the resource to not assign a drive letter by default when adding
+    a disk access path. Adding a Set-Partition -NoDefaultDriveLetter
+    $NoDefaultDriveLetter block defaulting to true.
+    When adding access paths the disks will no longer have
+    drive letters automatically assigned on next reboot which is the desired
+    behavior - Fixes [Issue #145](https://github.com/PowerShell/StorageDsc/issues/145).
+
 ## 4.4.0.0
 
 - Refactored module folder structure to move resource to root folder of
