The most recent version of the Release Notes is available online at https://www.suse.com/releasenotes.

These Release Notes are identical across all supported architectures.

Entries can be listed multiple times if they are important and belong to multiple sections.

Release notes usually only list changes that happened between two subsequent releases. Certain important entries from the release notes documents of previous product versions may be repeated. To make such entries easier to identify, they contain a note to that effect.

Repeated entries are provided as a courtesy only. Therefore, if you are skipping one or more service packs, check the release notes of the skipped service packs as well. If you are only reading the release notes of the current release, you could miss important changes.

2 SUSE Linux Enterprise High Availability Extension

SUSE Linux Enterprise High Availability Extension is an affordable, integrated suite of robust open source clustering technologies that enable enterprises to implement highly available Linux clusters and eliminate single points of failure. Used in combination with SUSE Linux Enterprise Server, it helps organizations maintain business continuity, protect data integrity, and reduce unplanned downtime for their mission-critical Linux workloads.

SUSE Linux Enterprise High Availability Extension provides all essential monitoring, messaging, and cluster resource management functionality of proprietary third-party solutions, but at a more affordable price, making it accessible to a wider range of enterprises.

The tight integration of SUSE Linux Enterprise High Availability Extension and SUSE Linux Enterprise Server ensure that the most robust, secure, and up-to-date high availability solution. Based on an innovative, highly flexible policy engine, it supports a wide range of clustering scenarios.

With static or stateless content, the High Availability cluster can be used without a cluster file system. This includes web services with static content as well as printing systems or communication systems like proxies that do not need to recover data.

Finally, its open-source license minimizes the risk of vendor lock-in, and its adherence to open standards encourages interoperability with industry standard tools and technologies.
