    openEuler Versions and Lifecycle

    Dual track: LTS and innovation

    Section titled “Dual track: LTS and innovation”

    openEuler ships on a dual track: the official download page states it plainly — community releases are classified into Long Term Support (LTS) versions and innovation versions. Production follows an LTS line through SP updates; new-feature validation rides the innovation line.

    Current versions and planned end dates

    Section titled “Current versions and planned end dates”
    Major Status GA EOL Kernel
    26.09 In development 2026-09 2027-03 6.6+ / 6.18
    24.03-LTS-SP4 Current 2024-06 2027-03 6.6

    Lifecycle dates are the planned end of support (YYYY-MM); status badges are evaluated at build time. The upstream project is authoritative: Official openEuler website.

    The innovation entry on the official download page is 26.09 (Innovation Versions) — a dual-kernel release on the Linux 6.6+ and 6.18 kernels for early validation; its planned end date and kernel baseline follow the table and the official download page.

    The current LTS entry is 24.03 LTS SP4 (Long-Term Supported Versions), officially described as built on kernel 6.6 for server, cloud and AI scenarios; its planned end date is in the table above.

    22.03 and historical versions

    Section titled “22.03 and historical versions”

    The official repo tree still carries the 22.03-LTS line (SP1–SP4) and 24.03-LTS (SP1–SP4) directories, but the download page’s current list features 26.09 and the 24.03 SP3/SP4 entries — the 22.03 line is no longer listed there, and historical versions live on the archives site. Machines still on 22.03 should follow official lifecycle announcements rather than reading “repo directory exists” as “still maintained”.

    Architecture support

    Section titled “Architecture support”

    The official download page states openEuler supports x86, AArch, Arm and RISC-V architectures. Media is published per-architecture — see Download and verify.

    Kernel identity

    Section titled “Kernel identity”
    Terminal window
    uname -r                  # includes the kernel version and openEuler build tag
    cat /etc/openEuler-release

    Kernel baselines follow the release line; each version’s kernel is stated on the official download page (this site keeps no static snapshot). For the dual-kernel trade-offs see Kernel and drivers.

    Relation to the EL family

    Section titled “Relation to the EL family”

    openEuler carries no compatibility promise with RHEL: its own kernel branch and a full package build system, keeping only the RPM/DNF operating habits. See the hub’s EL lifecycle timeline for the EL family timeline.
