 ## Release notes
 
-### Current release: Version 0.4368.1
+### Current release: Version 0.4578.0
+
+- Added support for configuring the Briefing Email for your organization at the user level with **Set-UserBriefingConfig** and **Get-UserBriefingConfig** cmdlets.
+
+- Support for session cleanup using **Disconnect-ExchangeOnline** cmdlet. This cmdlet is the V2 equivalent of `Get-PSSession | Remove-PSSession`. In addition to cleaning up session object and local files, it also removes the access token from cache, which is used for authenticating against V2 cmdlets.
+
+- You can now use `FolderId` as an identity parameter in **Get-EXOMailboxFolderPermission**. You can get the `FolderId` value using **Get-MailboxFolder**. For example:
+
+  `Get-MailboxFolderPermission -Identity <UPN>:<Folder-Path>`
+  
+  `Get-MailboxFolderPermission -Identity <UPN>:\<Folder-Id>`
+
+- Improved reliability of **Get-EXOMailboxStatistics** as certain request routing errors which led to failures have been resolved.
+
+- Optimized memory usage when a session is created by re-using any existing module with a new session instead of creating a new one every time session is imported.
