#1277 - retrieve deprecated terms

CHANGELOG.md

@@ -36,6 +36,7 @@ The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/).
 - Added capability to Debug the module in Visual Studio. [#1880](https://github.com/pnp/powershell/pull/1880)
 - Added `Set-PnPTeamsChannelUser` cmdlet to update the role of user in a private channel. [#1865](https://github.com/pnp/powershell/pull/1865)
 - Added `Restart-PnPFlowRun` which allows for a failed Power Automate flow run to be retried [#1915](https://github.com/pnp/powershell/pull/1915)
+- Added `-IncludeDeprecated` parameter to `Get-PnPTerm` cmdlet to fetch deprecated terms if specified [#1903](https://github.com/pnp/powershell/pull/1903)
 
 ### Changed
 - Changed `Sync-PnPSharePointUserProfilesFromAzureActiveDirectory` to map users based on their Ids instead which should resolve some issues around user identities reporting not to exist. You can use the new `-IdType` option to switch it back to `PrincipalName` if needed.  [#1752](https://github.com/pnp/powershell/pull/1752)
