bdev_set_options RPC making iobuf use in bdev configurable.
bdev_raid
Added support for rebuild in raid1 and raid5f levels.
Added superblock argument to bdev_raid_create RPC to allow writing out raid metadata to
a superblock. It can be then re-created from examined base bdevs, without the need
to issue bdev_raid_create.
Added bdev_raid_add_base_bdev RPC to add a base bdevs to an existing raid bdev.
Added bdev_raid_set_options RPC that changes options for raid bdev module,
currently allows setting process_window_size_kb affecting background operations
like rebuild.
blobstore
Added spdk_bs_grow_live() and spdk_bdev_update_bs_blockcnt() API that can be used to
increase size of blobstore filling the underlying device without first closing the blobstore.
env
Added SPDK command line parameter --no-huge, which enables SPDK to run without hugepages.
event
Added SPDK command line parameter --interrupt-mode, which enables to run SPDK in interrupt
mode. Effective only if all components used in the application, support interrupt mode.

Added rpc_bdev_ftl_get_properties and bdev_ftl_set_property RPC with matching API calls,
to allow modification of FTL device properties.
idxd
Added spdk_idxd_submit_dif_check() and spdk_idxd_submit_dif_insert() API to support
new operations for computing Data Integrity Field (DIF).
json
Added spdk_json_write_uuid(), spdk_json_write_named_uuid() and spdk_json_decode_uuid()
to help with writing and decoding UUID.
nvme
A new transport option rdma_max_cq_size was added to limit indefinite growth of CQ size.
Added spdk_nvme_ctrlr_cmd_iov_raw_with_md() API to allow sending larger passthru commands.
nvmf
Added max_discard_size_kib and max_write_zeroes_size_kib to nvmf_create_subsystem RPC to set the
maximum discard size and maximum write zeroes size.
Added new optional --ana-state (or shortly -n) parameter to nvmf_subsystem_add_listener RPC.
Added public APIs spdk_nvmf_subsystem_get_ana_reporting() and spdk_nvmf_subsystem_set_ana_state(),
replacing the internal functions nvmf_subsystem_get_ana_reporting() and nvmf_subsystem_set_ana_state()
respectively.
Added support for NVMe-oF referrals in NVMe-oF target with addition of
spdk_nvmf_tgt_add_referral() and spdk_nvmf_tgt_remove_referral() API and nvmf_discovery_add_referral,
nvmf_discovery_remove_referral and nvmf_discovery_get_referrals RPC.
Added spdk_nvmf_set_custom_ns_reservation_ops() API allowing to register custom handlers for reservation
operations.
scsi
Added support for SPDK_SBC_WRITE_SAME_10 and SPDK_SBC_WRITE_SAME_16.
thread
Added iobuf_get_stats RPC and spdk_iobuf_get_stats() API to track iobuf use across components.
env
Added SPDK command line parameter --no-huge, which enables SPDK to run without hugepages.
nvme
A new transport option rdma_max_cq_size was added to limit indefinite growth of CQ size.
nvmf
Added max_discard_size_kib and max_write_zeroes_size_kib to nvmf_create_subsystem RPC to set the
maximum discard size and maximum write zeroes size.
Added new optional --ana-state (or shortly -n) parameter to nvmf_subsystem_add_listener RPC.
Added public APIs spdk_nvmf_subsystem_get_ana_reporting() and spdk_nvmf_subsystem_set_ana_state(),
replacing the internal functions nvmf_subsystem_get_ana_reporting() and nvmf_subsystem_set_ana_state()
respectively.
scsi
