The storage filesystem that anchors countless home NAS boxes, self-hosted servers, and enterprise arrays has a fresh point release. OpenZFS 2.2.10 is out, the latest maintenance update to the 2.2 series and another routine increment to the branch most production Linux deployments actually run.
Version 2.2 is OpenZFS's long-term-support line, the one tagged for stability rather than new features. Point releases like this one exist to keep the out-of-tree kernel module building against the kernels shipped by distributions such as Debian, Ubuntu LTS, and RHEL, and to fold in bug fixes backported from the development branch. The tag was cut and signed by Tony Hutter, who shepherds the 2.2 LTS releases. For anyone running ZFS on root, a mirrored pool, or a backup target, the LTS branch is the conservative default, and updates here are about preserving that stability across kernel upgrades rather than chasing new capabilities.
Development momentum has moved to the newer 2.4 series, which carries the recent on-disk and performance work along with support for the latest mainline kernels. Sticking with the 2.2 line trades those additions for a longer patch window and broader compatibility with the slower-moving kernels common on servers. Both branches are maintained in parallel, so the choice comes down to whether a deployment values bleeding-edge kernel support or a stable target.
The release is available now from the project's GitHub as source tarballs, with packaging for major distributions following through their usual channels. Documentation and installation guides remain at zfsonlinux.org and the OpenZFS site.
