Images can now be instantly imported from local files, remote + files served over HTTP(S) or remote S3 buckets in ``raw`` (``rbd export v1``) + or basic ``qcow`` and ``qcow2`` formats. Support for ``rbd export v2`` + format, advanced QCOW features and ``rbd export-diff`` snapshot differentials + is expected in future releases. + +* Initial support for client-side encryption has been added. This is based + on LUKS and in future releases will allow using per-image encryption keys + while maintaining snapshot and clone functionality -- so that parent image + and potentially multiple clone images can be encrypted with different keys. + +* A new persistent write-back cache is available. The cache operates in + a log-structured manner, providing full point-in-time consistency for the + backing image. It should be particularly suitable for PMEM devices. + +* A Windows client is now available in the form of ``librbd.dll`` and + ``rbd-wnbd`` (Windows Network Block Device) daemon. It allows mapping, + unmapping and manipulating images similar to ``rbd-nbd``. + +* librbd API now offers quiesce/unquiesce hooks, allowing for coordinated + snapshot creation. + RGW object storage ~~~~~~~~~~~~~~~~~~
