@ -8,6 +8,24 @@ Legacy INI style configuration for SPDK applications has been deprecated and wil
removed in future release.
Please switch to JSON-RPC configuration files and/or RPC driven run-time configuration.
### copy
The copy engine library, modules and public APIs have been renamed. Use of the word `copy`
has been replaced with the word `accel` short for accelerator in preparation for adding new
capabilities in the future. Additionally, APIs for what was previously called the `memcpy`
engine have been renamed to identify the engine as a software accelerator.
### crypto
Support for AES_XTS was added for the QAT polled mode driver (pmd). The create RPC
`bdev_crypto_create` has 2 new optional parameters: cipher and key2. Cipher can be either
AES_CBC (default) or AES_XTS. AES_XTS is only valid when using the QAT polled mode driver.
The key2 parameter is the second key required for AES_XTS.

code includes two pre-defined configurations of IDXD groups/work queues/engines. A future
version will provide an interface to allow for setting of individual configuration
parameters.
IDXD is not yet available so this feature should be considered experimental. It will
be built up with additional documentation as an ongoing activity.
### ocf
Update OCF submodule to OCF v20.03
New version of OCF comes with API changes and bug fixes
### nvme
Export internal nvme_ctrlr_cmd_security_receive/send() APIs as public APIs with "spdk_"
prefix.
Added `priority` field in `spdk_nvme_transport_id`, this field is used to specify the priority
of the NVMe-oF connection, and currently it is used for NVMe-oF tcp connection.

### iSCSI
### iscsi
The iSCSI target now creates a lightweight thread per poll group instead of assuming a pool
of lightweight threads already exist at start up time. A poll group is a collection of
unrelated iSCSI connections. Each poll group is only accessed from the associated
lightweight thread.
### vmd
### miscellaneous
A new function, `spdk_vmd_fini`, has been added. It releases all resources acquired by the VMD
library through the `spdk_vmd_init` call.
The `--json-ignore-init-errors` command line parameter has been added to ignore
initialization errors on JSON config load.
The public header file io_channel.h has been removed. Please use thread.h which has the
exact same API.

numbers based on serial number arithmetic.

A new RPC `thread_set_cpumask` has been added to set the cpumask of the thread
to the specified value.
A new RPC `thread_get_pollers` has been added to retrieve pollers of SPDK threads.
A new RPC `thread_get_pollers` has been added to retrieve pollers from SPDK threads.
A new RPC `thread_get_io_channels` has been added to retrieve I/O channels of SPDK threads.

### sock
The `spdk_sock_set_priority` function has been removed since the feature to set the sock priority
will be contained in two new functions, i.e., `spdk_sock_listen_ext` and `spdk_sock_connect_ext`.
