Introduction

Welcome to the dedicated web page for the beta of SUSE Linux Enterprise Server (SLES®) 16.1, SUSE Linux Enterprise for SAP applications 16.1 (SLES for SAP) and SUSE Linux Enterprise High Availability Extension 16.1 (SLEHA). They are all part of the SUSE Linux products family, thus are sharing the same core and have the same planned releases dates, from Beta to First Customer Shipment.  

Immutability Meets SLES

The standout evolution in this release is all about flexibility and resilience. By integrating the immutable architecture pioneered by SUSE Linux Micro directly into SUSE Linux Enterprise Server (SLES), we are offering immutability capabilities to our entire SUSE Linux Enterprise Server customer base.

What does this mean for your business? This architectural shift enables highly resilient deployments with immutable capabilities—powered by transactional, atomic updates—making it ideal mission-critical workloads requiring ultra-resiliency.

At the same time, we know that choice matters. If your workloads require a classic Linux approach, you can seamlessly choose Standard Mode, featuring traditional read-write partitions. The choice is entirely yours, giving you the best of both worlds within a single, unified enterprise platform.

What Else is Coming?

Beyond immutability, SUSE Linux 16.1 focuses heavily on hardening security, streamlining systems management, and updating developer environments. Here is a look at the major capabilities for this release:

  • Agentic AI via MCP: We are rolling out deeper AI integration capabilities with new Model Context Protocol (MCP) components (in tech preview) and extending the management ecosystem with companies like Fujitsu/FSAS, n8n, Revenium and Stacklok, and major cloud providers AWS, Google Cloud, Microsoft Azure and Oracle. (Check this video of Rick Spencer & Craig McLuckie in Techstrong TV)
  • Built-in Real-Time Capabilities: The previously separated real time capabilities are now integrated directly into SLES right out of the box. This means you will be able to count on the same SLES for your Real-Time projects.
  • Browser-Based Installation & Management: Remote administration is getting a deeper polished upgrade. Expect an improved next-generation, API-driven Agama browser-based installer and updated Cockpit management.
  • Easy graphical Snapshot Management: Best of all, you will be able to manage BTRFS and Snapper Snapshots directly from Cockpit.
  • Ironclad Security: To meet strict compliance demands, the platform is targeting top-tier security certifications, including FIPS-140-3 and Common Criteria among others.
  • Modernized Developer Stacks: Ready to build? The release features refreshed versions of essential development tools, including GCC, PHP, Python, Java and Node.js. Build on Linux.
  • Updated Applications: Updated database and infrastructure components like PostgreSQL and MariaDB to deliver better features and performance.
  • Future-Proof Infrastructure: SUSE Linux 16.1 provides the foundational requisites for future modernization by making Arm a first-class citizen, enabling reproducible builds, and introducing new hardware support.
  • Smooth Transitions: Seamless upgrade paths from SLES 15 merge with, SUSE Linux Enterprise Real Time, SUSE Linux Micro and openSUSE are being designed to make transitions frictionless.

Planned Releases

  • Our plan is to release one Open Beta, and three Public Release Candidates.

  • Important : Please note that we reserve the right to change or adapt this schedule depending on various factors. Rest assured that we will communicate if there is any change to the plan.
