+---
+
+Cockpit is the [modern Linux admin interface](https://cockpit-project.org/).
+We release regularly.
+
+Here are the release notes from Cockpit 335 and cockpit-machines 329:
+
+
+## Storage: SMART device health
+
+The Storage page now shows disk device health and can run disk self-check tests on demand.

+
+## Machines: Fix remote viewer launching
+
+The "Launch viewer" button in Cockpit Machines now reliably launches "virt-viewer". The fix adds a generated filename to the `application/x-virt-viewer` helper file, resolving browser-specific launch issues. The filename also clarifies the file's purpose in the downloads folder.
+
+
