SPDK v21.04: ZNS NVMe bdev, PMR, ADQ initiator, RPM
On behalf of the SPDK community I’m pleased to announce the release of SPDK 21.04!!
This release contains the following new features:
- ZNS NVMe bdev: Added support for zoned namespaces to the NVMe bdev module. This builds on the work to support zoned namespaces in the NVMe driver in the previous release.
- NVMe PMR: Added support for the Persistent Memory Region feature to NVMe driver.
- NVMe-oF ADQ: Added support for Application Device Queues (ADQ) to the NVMe-oF TCP initiator.
- RPM: Added script for building SPDK RPM packages. See RPM documentation.
Users updating from the previous release should note that a large number of deprecated APIs have been removed. The process for deprecation has been formalized in deprecated.md, where a list of deprecation notices for future releases can be found.
The full changelog for this release is available here.
This release contains 730 commits from 49 authors with over 29k lines of code changed.
