Leap Micro 5.5 Launches, Leap Micro 5.3 Reaches End of Life

openSUSE has announced the availability of Leap Micro 5.5, the latest version of its modern lightweight host operating system. Leap Micro 5.5 is essentially a rebranded version of SLE Micro, so all the documents and release notes from SLE Micro 5.5 are applicable to Leap Micro as well.

It’s important to note that with the release of Leap Micro 5.5, Leap Micro 5.3 has reached its End of Life (EOL). Users of Leap Micro 5.3 are strongly advised to upgrade to either the Leap Micro 5.4 or 5.5 release to ensure access to the latest features, security enhancements, and ongoing support.

One of the standout features of Leap Micro 5.5 is its enhanced support for SELinux. Security-Enhanced Linux (SELinux) now includes podman-docker and hyper-v support for AArch64, providing users with a more robust and secure computing experience. Leap Micro 5.5 also includes podman 4.4, which introduces podman quadlets. Users can check out the Nextcloud deployment using quadlets to explore this feature. Additionally, Leap Micro ships with podman-docker, a podman wrapper that can be used together with docker-compose.

The container management interface Cockpit has also received notable improvements in version 298. Users can now use Cockpit to manage all of their home workloads, providing a more convenient management solution.

For users new to the immutable OS space, which consists of systems with read-only /root, there is a transactional update guide available to help navigate the update process. Additionally, users can use the Toolbox tool to install additional software without the need for a reboot, making it particularly useful for debugging scenarios where a reboot is not feasible.
