1.2.0 (2014-10-03):

  • blkback: add 'force_close' to more forcibly tear down the device

  • blkback: make 'destroy' idempotent

  • blkback: measure ring utilisation; segments per request; total requests and responses (ok and error)

  • blkback: support indirect descriptors (i.e. large block sizes)

  • blkfront: if the 'connect' string is at all ambiguous, fail rather than risk using the wrong disk

  • blkfront: use indirect segments if available

1.1.0 (2014-01-30):

  • blkback: functorise over Activations.

  • Depend on xen-grant and xen-event libraries rather than xenctrl.
