## v19.01: (Upcoming Release)
### ocf bdev
New virtual bdev module based on [Open CAS Framework](https://open-cas.github.io/) has been added.
This module allows for the use of one bdev to act as a high performance cache in front of another bdev.
Please see [documentation](https://spdk.io/doc/bdev.html#bdev_config_cas) for more details.
Only write through mode is currently supported and this feature is considered experimental.

memory size can be still set with `-s` or `--mem-size` option, although the default value
was reduced down to 0.
A custom hugetlbfs directory can now be specified via spdk_app_opts.
This can be used to configure hugepages with different sizes, a different size limit,
or different access permissions than the system's default hugepage pool.
SPDK applications can specify a custom hugetlbfs mount with the `--huge-dir` option.

Added `spdk_strtol` and `spdk_strtoll` to provide additional error checking around `strtol`
and `strtoll`.
Added `spdk_sprintf_append_realloc` and `spdk_vsprintf_append_realloc` for appending a string
with automatic buffer re-allocation.

Added fields `num_shared_buffers` and `buf_cache_size` in struct spdk_nvmf_transport_opts,
and also updated the related rpc function nvmf_create_transport, to make this
configurable parameter available to users. The `num_shared_buffers` is used to
configure the shared buffer numbers of the transport used by RDMA or TCP transport.
`buf_cache_size` configures number of shared buffers to cache per poll group.
### nvmf
@ -108,8 +127,18 @@ Add a new TCP/IP transport (located in lib/nvmf/tcp.c). With this tranport,
the SPDK NVMe-oF target can have a new transport, and can serve the NVMe-oF
protocol via TCP/IP from the host.
Added optional mechanism to modify the RDMA transport's behavior when creating protection domains and registering memory.
By default, the RDMA transport will use the ibverbs library to create protection domains and register memory.
Using `spdk_nvme_rdma_init_hooks` will subvert that and use an existing registration.
### bdev
Added `enable_bdev_histogram` and `get_bdev_histogram` RPC commands to allow gathering latency data for specified bdev.
Please see [documentation](https://spdk.io/doc/bdev.html#rpc_bdev_histogram) for more details.
Added `required_alignment` field to `spdk_bdev`, that specifies an alignment requirement for data buffers associated with an spdk_bdev_io.
Bdev layer will automatically double buffer any spdk_bdev_io that violates this alignment, before the spdk_bdev_io is submitted to the bdev module.
On shutdown, bdev unregister now proceeds in top-down fashion, with
claimed bdevs skipped (these will be unregistered later, when virtual
bdev built on top of the respective base bdev unclaims it). This

The `delete_bdev` RPC is now deprecated. Users should instead use the specific deletion RPC

Added support for separate bandwidth rate limits for read and write to QoS in bdev layer.
Bdev I/O statistics now track unmap opertations.

SCSI target hotremove can now be performed even without the VIRTIO_SCSI_F_HOTPLUG feature negotiated.
Regardless of VIRTIO_SCSI_F_HOTPLUG support, the hotremoval will be still reported through SCSI sense codes.

### net framework
Net framework initialization and finish is now done asynchronously.
### rpc
Added `spdk_rpc_is_method_allowed` function for checking whether method is permitted in a given state.
Added `spdk_rpc_get_state` to check current state of RPC server.
RPC `wait_subsystem_init` has been added to allow clients to block untill all subsystems are initialized.
### json rpc
JSON RPC client is now running in non-blocking mode. Requests are sent and received during spdk_jsonrpc_client_poll.
JSON RPC server can now recieve a callback on connection termination or server shutdown using `spdk_jsonrpc_conn_add_close_cb`
and `spdk_jsonrpc_conn_del_close_cb`.
