+==== Bug fixes
+
+* Before this update, the `catalog-operator` captured snapshots every five minutes, which caused CPU spikes when dealing with many namespaces, subscriptions, and large catalog sources. This increased load on the catalog source pods and prevented users from installing or upgrading operators. With this release, the catalog snapshot cache lifetime has been increased to 30 minutes allowing enough time for the catalog source to resolve attempts without causing an undue load and stabilizing the operator installation and upgrade process. (link:https://issues.redhat.com/browse/OCPBUGS-57429[OCPBUGS-57429])
+
+* Before this update, forward slashes were permitted in the `console.tab/horizontalNav` `href` values. Starting in 4.15, a regression resulted in the forward slashes no longer working correctly when used in `href` values. With this release, forward slashes in `console.tab/horizontalNav` `href` values continue to work as expected. (link:https://issues.redhat.com/browse/OCPBUGS-59358[OCPBUGS-59358])
