Upcoming release
----------------
v16.08: iSCSI target, NVMf maturity
-----------------------------------
This release adds a userspace iSCSI target. The iSCSI target is capable of exporting
NVMe devices over a network using the iSCSI protocol. The application is located
in app/iscsi_tgt and a documented configuration file can be found at etc/spdk/spdk.conf.in.
- NVMe
- The Weighted Round Robin arbitration method is now supported. This allows
the user to specify different priorities on a per-I/O-queue basis. To
enable WRR, set the `arb_mechanism` field during `spdk_nvme_probe()`.
- A simplified "Hello World" example was added to show the proper way to use
the NVMe library API; see `examples/nvme/hello_world/hello_world.c`.
- NVMe over Fabrics
This release also significantly improves the existing NVMe over Fabrics target.
- The configuration file format was changed, which will require updates to
any existing nvmf.conf files (see `etc/spdk/nvmf.conf.in`):
- `SubsystemGroup` was renamed to `Subsystem`.

- `nvmf_tgt` was updated to correctly recognize NQN (NVMe Qualified Names)
when naming subsystems. The default node name was changed to reflect this;
it is now "nqn.2016-06.io.spdk".
- `Port` and `Host` sections were merged into the `Subsystem` section
- Global options to control max queue depth, number of queues, max I/O
size, and max in-capsule data size were added.
- The Nvme section was removed. Now a list of devices is specified by
bus/device/function directly in the Subsystem section.
- Subsystems now have a Mode, which can be Direct or Virtual. This is an attempt
to future-proof the interface, so the only mode supported by this release
is "Direct".
- Many bug fixes and cleanups were applied to the `nvmf_tgt` app and library.
- The target now supports discovery.
This release also adds one new feature and provides some better examples and tools
for the NVMe driver.
- The Weighted Round Robin arbitration method is now supported. This allows
the user to specify different priorities on a per-I/O-queue basis. To
enable WRR, set the `arb_mechanism` field during `spdk_nvme_probe()`.
- A simplified "Hello World" example was added to show the proper way to use
the NVMe library API; see `examples/nvme/hello_world/hello_world.c`.
- A test for measuring software overhead was added. See `test/lib/nvme/overhead`.
