Each square is one capability area in one year. The brighter it is, the more the area gained in the Enterprise Linux Ledger that year; 1, 2 and 3 mark that year's biggest pushes.

no change+0.5+1+1.5 or moreScores out of 5 per area.
Biggest pushes overall: Containers and Kubernetes host (+1.5), AI and GPU readiness (+1.5), Software currency and packaging (+1). Already strong in 2015: Storage and filesystems, Lifecycle and upgrades, Hardware and architectures.
Top focus each year: 2018 Software currency and packaging; 2021 Containers and Kubernetes host; 2025 AI and GPU readiness. 8 of 11 years show no gain in any area.
Owner: SUSE S.A. (private; owned by EQT since the 2023 take-private; a sale process was reported in March 2026)
Licence: Open-source components; update repositories, support and extensions need a subscription per socket pair or per VM (list prices are not published)
Support lifecycle: 16 family: general support to 2035-11-30, LTS to 2038-11-30, each 16.x minor 2 years general plus 3 years LTS; 15 SP7: general to 2031-07-31, LTSS to 2034-07-31
Next milestone: 16.1 general availability planned for November 2026 (lifecycle page)
Support window: 15 line: 13 years (10 general plus 3 LTSS); 16 line: 13 years per family with 2 plus 3 years per minor; source: suse.com/lifecycle
Tier: Commercial subscription
Archetype: Dependable builder
Evidence grade: B. The lifecycle page, the 16.0 release notes, the SLE 15 release notes and the Multi-Linux Manager 5.1 release notes were read directly. Release dates for the 15 service packs come from endoflife.date, the 16.1 beta facts from a SUSE blog post, and the ownership story from press reports. The start dates of Arm64 support, kernel live patching and the Rancher products could not be re-read, so those steps are dated at the first primary source that confirms them.
AI say-do, 2023 to 2026: 4 AI items announced; 1 GA, 3 still preview, 0 pending, 0 dropped. SUSE AI counts as GA on the strength of its 1.0 documentation; mcphost, the 16.1 MCP components and the AI Factory with NVIDIA are previews.
SLES runs GPU workloads through NVIDIA's own repositories and leaves the AI platform to SUSE AI on SUSE Linux Micro, which is a different product with a different lifecycle. Its own AI items are MCP previews; nothing AI-assisted operates SLES itself yet.
Reading
SLES is the most predictable of the commercial three in what it ships and when: a service pack every June for seven years, then 16.0 on the day the lifecycle page named. The 16 line is a bigger change than the version number suggests, with SELinux replacing AppArmor, a new installer, a two-year window per minor and POWER9 and older x86 CPUs dropped, so a 15 to 16 move is a project, not a patch. Capability is strong across the board and Multi-Linux Manager is the widest fleet tool in the group. The thing to check before signing is the owner: EQT took SUSE private in 2023 and a sale was reported in March 2026, and SUSE does not publish list prices, so put price and term protection into the contract.
Open questions and items to re-score
SLES 16.0 end date is stated two ways: the lifecycle page gives general support to 2027-11-30 and LTS to 2030-11-30, the 16.0 release notes say 'fully maintained and supported until 31 Jul 2034' (extendable to December 2037). The Ledger uses the lifecycle page; confirm with SUSE before planning.
SLES 16.1 general availability: planned for November 2026 on the lifecycle page; the beta opened 2026-05-28 and RC2 shipped 2026-07-31.
FIPS 140-3: 16.0 is 'prepared' and 16.1 'targets' certification; no certificate found for the 16 line.
SUSE AI general availability date and the AI Factory with NVIDIA (preview per secondary sources) were not confirmed from primary pages.
The reported Rancher AI assistant, Liz agent and a Multi-Linux Manager MCP server rest on secondary sources only (grade C) and did not move any score.
Start dates not re-read from primary sources (grade C): Arm64 support in the 12 line, kernel live patching (kGraft) in SLES 12, Rancher RKE2 and K3s support on SLES, DISA STIG profiles for SLES 15. Earlier years may be understated by half a step in hardware and containers.
Whether the EQT sale process concluded after March 2026, and whether list prices changed since 2023 (SUSE sells through partners).
