Hi sheepdog users and developers,

I released sheepdog v0.9.0. This release has some important
long-awaited features and bunch of bugfixes. Quoting from

 - new object reclaim scheme: Sheep uses new garbage collection
   algorithm for reclaiming objects. Disk consumption of deleted VDIs
   are reduced dramatically.
 -- In addition, the limitation of maximum number of children
    (snapshots and clones) is resolved. Creating more than 1024
    snapshots or clones from single virtual disk is allowed.

 - iSCSI multipath: now tgtd isn't a single point of failure

 - VDI locking: opening single VDI by multiple QEMU process is not

But you should be careful about some points:
 - v0.8.x and v0.9.0 isn't compatible. Currently, you cannot update
   your existing cluster in-place manner.

 - The critical bug related to gateway node still remains
   (https://bugs.launchpad.net/sheepdog-project/+bug/1327037). If you
   don't use gateway nodes, you don't have to care about it. The
   problem will be fixed in v0.9.1.
