 ### New Features {#new-features-1-128-0}
-* Demoted releases will now be hidden from the Version History page, removing a prior limitation in KOTS and kURL installations.
+* In online (internet-connected) KOTS existing cluster and kURL installations, demoted releases are hidden from the Admin Console **Version History** page after an update check occurs. This addresses a limitation in KOTS and kURL installations where a demoted release would remain viewable on the **Version History** page if the user had already checked for upstream updates before it was demoted.
