OpenZFS uses the MAJOR.MINOR.PATCH versioning scheme described here:
|
||
|
|
|
||
|
|
* MAJOR - Incremented at the discretion of the OpenZFS developers to indicate
|
||
|
|
a particularly noteworthy feature or change. An increase in MAJOR number
|
||
|
|
does not indicate any incompatible on-disk format change. The ability
|
||
|
|
to import a ZFS pool is controlled by the feature flags enabled on the
|
||
|
|
pool and the feature flags supported by the installed OpenZFS version.
|
||
|
|
Increasing the MAJOR version is expected to be an infrequent occurrence.
|
||
|
|
|
||
|
|
* MINOR - Incremented to indicate new functionality such as a new feature
|
||
|
|
flag, pool/dataset property, zfs/zpool sub-command, new user/kernel
|
||
|
|
interface, etc. MINOR releases may introduce incompatible changes to the
|
||
|
|
user space library APIs (libzfs.so). Existing user/kernel interfaces are
|
||
|
|
considered to be stable to maximize compatibility between OpenZFS releases.
|
||
|
|
Additions to the user/kernel interface are backwards compatible.
|
||
|
|
|
||
|
|
* PATCH - Incremented when applying documentation updates, important bug
|
||
|
|
fixes, minor performance improvements, and kernel compatibility patches.
|
||
|
|
The user space library APIs and user/kernel interface are considered to
|
||
|
|
be stable. PATCH releases for a MAJOR.MINOR are published as needed.
|
||
|
|
|
||
|
|
Two release branches are maintained for OpenZFS, they are:
|
||
|
|
|
||
|
|
* OpenZFS LTS - A designated MAJOR.MINOR release with periodic PATCH
|
||
|
|
releases that incorporate important changes backported from newer OpenZFS
|
||
|
|
releases. This branch is intended for use in environments using an
|
||
|
|
LTS, enterprise, or similarly managed kernel (RHEL, Ubuntu LTS, Debian).
|
||
|
|
Minor changes to support these distribution kernels will be applied as
|
||
|
|
needed. New kernel versions released after the OpenZFS LTS release are
|
||
|
|
not supported. LTS releases will receive patches for at least 2 years.
|
||
|
|
The current LTS release is OpenZFS 2.1.
|
||
|
|
|
||
|
|
* OpenZFS current - Tracks the newest MAJOR.MINOR release. This branch
|
||
|
|
includes support for the latest OpenZFS features and recently releases
|
||
|
|
kernels. When a new MINOR release is tagged the previous MINOR release
|
||
|
|
will no longer be maintained (unless it is an LTS release). New MINOR
|
||
|
|
releases are planned to occur roughly annually.
