New driver. The headline is a brand-new Weka share driver landing at nearly 9,900 lines, adding another vendor backend to the tree.

Driver features. Dell backends saw the bulk of the remaining feature churn, with roughly 5,000 lines across PowerStore and PowerScale. PowerStore gained QoS support, manage/unmanage for both shares and share snapshots. PowerScale picked up its own QoS implementation and revert-to-snapshot. Underpinning the latter, the core manager gained support for asynchronous revert-to-snapshot, giving drivers a proper long-running code path for the operation. On the NetApp side, DHSS=True custom ipspaces are now cleaned up correctly via the REST API, and SnapMirror snapshots left behind after a DR replica promotion are deleted.

Stability. Several small but real bugs were squashed: two missing raise statements (one in the DB layer's NotFound handling, one in the NetApp SnapLock check, the latter backported), a share-group DB query that now skips share instances with no instance, and a policies operation-path fix. A missing set of driver config options were registered in opts.py.

Elsewhere. Devstack cross-service auth was fixed, plus api-ref, release-note and docstring touch-ups including an HPE revert-snapshot limitation note.
