 ### Important Upgrade Notes
  - Improved performance on data retention ``DeleteOrphanedRows`` queries. See the [Important Upgrade Notes](https://docs.mattermost.com/upgrade/important-upgrade-notes.html) for notes on a new migration that was added. Removed feature flag ``DataRetentionConcurrencyEnabled``. Data retention now runs without concurrency in order to avoid any performance degradation. Added a new configuration setting ``DataRetentionSettings.RetentionIdsBatchSize``, which allows admins to to configure how many batches of IDs will be fetched at a time when deleting orphaned reactions. The default value is 100.
+ - Minimum supported Desktop App version is now v5.3. OAuth/SAML flows were modified to include ``desktop_login`` which makes earlier versions incompatible.
 
 **IMPORTANT:** If you upgrade from a release earlier than v9.0, please read the other [Important Upgrade Notes](https://docs.mattermost.com/upgrade/important-upgrade-notes.html).
