Workarounds have been added to ensure vhost compatibility with QEMU 2.12.
EXPERIMENTAL: Support for vhost-nvme has been added to the SPDK vhost target. See the
[vhost documentation](http://www.spdk.io/doc/vhost.html) for more details.
### Unified Target Application
A new unified SPDK target application, `spdk_tgt`, has been added. This application combines the
functionality of several existing SPDK applications, including the iSCSI target, NVMe-oF target,
and vhost target. The new application can be managed through the existing configuration file and
[JSON-RPC](http://www.spdk.io/doc/jsonrpc.html) methods.

The bdev layer now allows modules to provide an optional per-bdev UUID, which can be retrieved with

Enforcement of IOPS limits for quality of service (QoS) has been added to the bdev layer. See the
