After a year of development, the launch of the new version of the popular Linux distribution, openSUSE Leap 15.4. The release is based on the same set of binary packages with SUSE Linux Enterprise 15 SP 4 with some custom applications from the openSUSE Tumbleweed repository.
Using the same binary packages in SUSE and openSUSE simplifies switching between distributions, saves resources on building packages, distributing updates, and testing, unifies differences in specification files, and lets you stop diagnosing different package builds when parse error messages.
In this new version of Leap 15.4 it is highlighted by Leap Micro 5.2, a modern, lightweight operating system that is immutable and ideal for host container and virtualized workloads. Leap Micro is ideal for decentralized computing environments, edge uses, and embedded/IoT deployments.
Leap Micro is a simplified distribution based on the Tumbleweed repository, which uses an atomic install system and automatic update enforcement, supports configuration via cloud-init, comes with a read-only root partition with Btrfs, and built-in runtime support for Podman/CRI-O and Docker . The main purpose of Leap Micro is to be used in decentralized environments, to create microservices and as a base system for virtualization platforms and container isolation.
One of the Leap Micro related packages for developers is Podman. Podman gives developers options to run their apps with Podman in production and the 3.4.2 updateThe release brings new pod support for ini containers
leap 15.4 continues to deliver a robust and familiar release and offers stable open source software for desktops, servers, containers and virtualized workloads,” said Max Lin, Release Team Member. “Leap is a hard distro for techies to ignore; security fixes, new technologies, and updated packages provide professionals with a well-designed community release that is identical to its enterprise twin. And it offers a huge amount of community software.”
As with the previous version of Leap, users can migrate to SUSE Linux Enterprise and let workloads run as normal. This release further improves migration proficiency because the YaST team developed a simplified migration tool for SLE migrations.
