Microsoft has announced that it will be deprecating support for regular OAuth in Azure Devops and requiring the use of Microsoft Entra OAuth.

Support for OAuth will end in 2026 (no specific date announced yet) and existing OAuth connections will work until then.  This change will impact the authentication method of the ADO connector in Jira Align.  

To prepare for this, we should work on adding support for Entra in the Jira Align ADO connector.
