# Changelog



## (Upcoming release) v17.07



### Build System



A `configure` script has been added to simplify the build configuration process.

The existing CONFIG file and `make CONFIG_...` options are also still supported.

Run `./configure --help` for information about available configuration options.



A DPDK submodule has been added to make building SPDK easier.  If no `--with-dpdk`

option is specified to configure, the SPDK build system will automatically build a

known-good configuration of DPDK with the minimal options enabled.  See the Building

section of README.md for more information.



A [Vagrant](https://www.vagrantup.com/) setup has been added to make it easier to

develop and use SPDK on systems without suitable NVMe hardware.  See the Vagrant

section of README.md for more information.



### NVMe driver



The NVMe driver has been updated to support recent Intel SSDs, including the Intel®

Optane™ SSD DC P4800X series.



A workaround has been added for devices that failed to recognize register writes

during controller reset.



The NVMe driver now allocates request tracking objects on a per-queue basis.  The

number of requests allowed on an I/O queue may be set during `spdk_nvme_probe()` by

modifying `io_queue_requests` in the opts structure.



The SPDK NVMe `fio_plugin` has been updated to support multiple threads (`numjobs`).



### Environment Abstraction Layer



The environment abstraction layer has been updated to include several new functions

in order to wrap additional DPDK functionality. See `include/spdk/env.h` for the

current set of functions.



## v17.03: Blobstore and userspace vhost-scsi target



### Blobstore and BlobFS
