 [Full CHANGELOG here](https://github.com/scrthq/PSGSuite/blob/master/CHANGELOG.md)
 
-#### 2.30.2
-
-* [Issue #212](https://github.com/scrthq/PSGSuite/issues/212)
-  * Fixed: `Get-GSUserLicense` no longer short circuiting after first license match when processing pipeline input
-  * Updated: License SKU order to check most common license types first for `Get-GSUserLicense`, which should result in faster overall processing when working with a large amount of users.
-
-#### 2.30.1
-
-* Miscellaneous
-  * Fixed: `Remove-GSDrivePermission` duplicate parameter alias prevented usage after module update.
-
-#### 2.30.0
-
-* [Issue #193](https://github.com/scrthq/PSGSuite/issues/193)
-  * Added: Drive Revision functions:
-    * `Get-GSDriveRevision`
-    * `Remove-GSDriveRevision`
-    * `Update-GSDriveRevision`
-* [Issue #210](https://github.com/scrthq/PSGSuite/issues/210)
-  * Fixed: `Update-GSUser` was not accepting User ID's as the User parameter
-* [Issue #209](https://github.com/scrthq/PSGSuite/issues/209)
-  * Added: Support for inline image downloading with `Get-GSGmailMessage` where the image is not included on the Attachments property of the parsed message object.
-  * Fixed: `Get-GSGmailMessage` will now automatically set the `Format` to `Raw` if either `ParseMessage` or `SaveAttachmentsTo` is passed, as `ParseMessage` is a requirement in order to be able to access the message attachments as needed.
-* [Issue #204](https://github.com/scrthq/PSGSuite/issues/204)
-  * Added: `Recurse` parameter to `Get-GSDriveFileList` to allow recursively listing all files and subfolders underneath the result set. Confirmed setting the `Limit` parameter also works as expected with `Recurse` included, stopping is the original limit is reached.
-  * Added: `Get-GSDriveFolderSize` function to return the calculated total size of the files in the specified folder(s).
+#### 2.31.0
+
+* [Issue #218](https://github.com/scrthq/PSGSuite/issues/218)
+  * Fixed: `Update-GSOrganizationalUnit` was failing with `null` reference errors.
+* [Issue #213](https://github.com/scrthq/PSGSuite/issues/213)
+  * Added: Support for `RELEASE_RESOURCES` TransferParam for Calendar application data transfers to function `Start-GSDataTransfer`
+* [Issue #215](https://github.com/scrthq/PSGSuite/issues/215)
+  * Added:
+    * `Get-GSDomain`
+    * `Remove-GSDomain`
+    * `New-GSDomain`
+    * `Get-GSDomainAlias`
+    * `New-GSDomainAlias`
+    * `Remove-GSDomainAlias`
+  * _These will need the additional scope of `https://www.googleapis.com/auth/admin.directory.domain` added in order to use!_
 * Miscellaneous
-  * Added: `Rfc822MsgId` parameter to `Get-GSGmailMessageList` to easily build a query looking for a specific RFS 822 Message ID.
-  * Added: Pipeline support for `*-GSDrivePermission` functions to enable piping Drive Files into them to manage permissions without looping manually.
+  * Added:
+    * `Get-GSCustomer`
+    * `Update-GSCustomer`
+    * `Add-GSCustomerPostalAddress`
+  * _These will need the additional scope of `https://www.googleapis.com/auth/admin.directory.customer` added in order to use!_
