+==== Configuration as code entry for 'myViewsTabBar' is deprecated.
+
+As of 2.528.1, the configuration as code entry for 'myViewsTabBar' has been deprecated.
+In its place, a new user property has been introduced that makes it possible for a user to override what is configured for the global dashboard or a folder.
+This will be seen as the Views Tab Bar in Jenkins.
+Instead of the 'myViewsTabBar', users can now select one of the implementations of 'ViewsTabBar' to be used for the My Views dashboard.
+The default view on the *My Views* configuration is a selectable option instead of checking if the user enters a valid view name.
+
+==== Container images update Debian from Bookworm to Trixie
+
+With the release of 2.528.1, the container images based on Debian are now using Debian 13 ("Trixie") instead of Debian 12 ("Bookworm").
+The upgrade to Trixie includes performance improvements and upgrades to Linux kernel 6.12 LTS for enhanced performance and hardware support.
+
+Users of the Debian based Jenkins container images may need to adjust their custom container images to adapt to the Debian upgrade.
+Please keep this in mind when using any Debian based Jenkins images and report issues in the link:https://github.com/jenkinsci/docker/issues[Jenkins Docker issue tracker].
+
+==== Timestamper plugin update
+
+If you have the plugin:timestamper[Timestamper] plugin installed, it must be upgraded to the link:https://plugins.jenkins.io/timestamper/releases/[latest version] before upgrading to Jenkins LTS 2.528.1.
+If the plugin is not updated prior to the Jenkins upgrade, you may encounter issues with the plugin compatibility and dependencies.
+If you mistakenly update to Jenkins 2.528.1 before updating the plugin, you will need to revert to the previous Jenkins version and update the Timestamper plugin before you can upgrade Jenkins again.
