openSUSE Leap 16.1 folds Leap Micro into an Immutable Mode, ships Plasma 6.6 and Python 3.14
Victoria Shinder1 min readThe openSUSE Project has released Leap 16.1, the first minor release in the Leap 16 series. Its main change is structural: openSUSE's immutable server distribution, Leap Micro, becomes part of Leap itself as an Immutable Mode. Users boot the regular install image and choose that mode in the Agama installer. The project says there will be no Leap Micro 6.3 or 7.0.
In Immutable Mode the root filesystem is read-only and the system is updated transactionally. Each update with transactional-update creates a new snapshot, and a single command rolls it back. Extra software comes through containers with Podman or Distrobox, or through Flatpak on the desktop. The preconfigured Leap Micro appliances remain available, including images for KVM/Xen, Hyper-V, VMware, Harvester and cloud, and Leap Micro 6.2 systems can migrate with the openSUSE Migration tool, a path the project still calls experimental.
The core stays on Linux 6.12, systemd 257 and glibc 2.40. KDE moves from Plasma 6.4 to 6.6 with Qt 6.11, GNOME stays on 48 with bug fixes, and LXQt goes to 2.4. Developers get Python 3.14 alongside the default 3.13, LLVM 21, PHP 8.5.12, MariaDB 12.3 and PostgreSQL 18; virtualisation moves to QEMU 11.0 and libvirt 12.4, containers to Podman 5.8. The minimum CPU level stays x86-64-v2 and SELinux remains the default security module.
The announcement originally said Leap 16.1 shipped on the same day as SUSE Linux Enterprise Server 16.1. The project has since corrected that: SLES 16.1 is expected later this month. Annual minor releases are planned up to Leap 16.6 in 2031.
What it means
For anyone running Leap Micro the decision is now a migration, not a wait for the next Micro version. One release and one life cycle for traditional and immutable installs also means one update stream to track.
