Lustre feature releases follow a release train model, with community releases targeted every six months.

The latest Long Term Support (LTS) release is Lustre 2.12.6 - see Lustre 2.12.6 Changelog for more details.
Older Lustre Releases and Feature Roadmap
The archive of older releases are also available here.
Users are encouraged to always run the latest version of e2fsprogs on their servers.
Lustre-enhanced GNU Tar
The Lustre-enhanced version of GNU tar is capable of backing up and restoring the Lustre layout for files. This requires that the user specify the --xattr option when backing up and restoring the files. The RHEL6.3 and derivative releases of GNU tar include Lustre specific enhancements, so the separate Lustre-enhanced GNU tar is not needed for those releases.
