+summary: "Handle unsupported storage partitions, link quadlet logs to their service, source mode for virtual networks, various UX improvements."
+---
+
+Cockpit is the [modern Linux admin interface](https://cockpit-project.org/).
+We release regularly.
+
+Here are the release notes from Cockpit 340, cockpit-podman 107, cockpit-machines 333, and cockpit-ostree 211:
+
+## Storage: Prevent modifying unsupported partitions
+
+Cockpit now detects unsupported partitions and displays a notice that Cockpit does not support it, such as modifying LVM2 Logical Volume partitions.
+
+![Screenshot showing a notice inside a GPT partitions card saying "Unexpected partitions" in bold, followed by a description saying "Partitions are not supported on this block device. If it is used as a disk for a virtual machine, the partitions must be managed by the operating system inside the virtual machine."]({{ site.baseurl }}/images/340-storage-unsupported-partitions.png)
+
+## Storage: Rename safety warning
+
+We now display a warning when renaming volume groups that contain the root filesystem as it might break the next boot.
+
+
+## Podman: Quadlet log links
+
+Quadlet logs now link to their systemd service log page counterpart.
+
+![An image of a podman logs page for a container called "systemd-test" below the black logs box is a link saying "View test.service logs".]({{ site.baseurl }}/images/340-quadlet-service-logs-link.png)
+
+## Machines: Virtual network interfaces can now select source mode
+
+When adding a new virtual network interface you can now select between VEPA, Bridge, Private, or Passthrough for more flexibility with how machines are exposed to the network.
+
+![Screenshot showing off new form selection, it includes an information button for "Source" as well as a radio button to select either VEPA, Bridge, Private, or Passthrough.]({{ site.baseurl }}/images/340-machines-network-source-mode.png)
