Chapter 1. Summary of changes

The 6.15 release of Red Hat Satellite features the following changes:

Removed katello-agent subsystem

katello-agent, qpid messaging system, and related Content settings have been removed from Satellite.
You have to migrate your hosts from katello-agent to remote execution before the upgrade. Remote execution is now the only way to perform remote package actions.
Red Hat recommends you to disable katello-agent on your Satellite Server and Capsule Servers before the upgrade.
Optionally, you can remove the katello-agent package from hosts. Red Hat recommends you to do so and verify that you can perform remote package actions by using remote execution.
See also katello-agent.

Security hardening support

You can enable fapolicyd on Satellite Server and Capsule Servers. For more information, see fapolicyd on Satellite and Capsule is now available.

The main Satellite menu in the Satellite web UI now reveals items on click instead of hover, it has three levels, and is searchable. For more information, see Vertical navigation changes.
The Satellite web UI displays a banner if the Satellite version is nearing or even past the end-of-life date. For more information, see Satellite EOL date in the web UI.
Users can subscribe to new email notifications for failed tasks. For more information, see Satellite sends email notifications after certain background actions fail.
Satellite can use Redis as the WebUI cache, which can handle greater load in larger setups. For more information, see Redis cache.
Satellite auto-selects the activation key during host registration in the Web UI. For more information, see Satellite auto-selects the activation key during host registration.
