On behalf of the SPDK community I’m pleased to announce the release of SPDK 20.04!

This release contains the following new features:

• SPDK Top: Added application to allow users to monitor resource consumption by a running SPDK application.
• NVMe qpair groups: Added API to allow for pooling of NVMe qpairs across a single entity.
• OCF: Added support for OCF v20.03.
• Crypto bdev: Added support for AES_XTS for the QAT polled mode driver.
• IDXD: Added support for IDXD as an accel plug-in module allowing for use with the generic accel framework API. This feature is considered experimental.

Note: Legacy INI style configuration for SPDK applications has been deprecated and will be removed in a future release. Please switch to JSON-RPC configuration files and/or RPC driven run-time configuration.

The full changelog for this release is available here.
