On behalf of the SPDK community I'm pleased to announce the release of SPDK 21.07!

This release contains the following new features:

- Kernel DSA: Added support in IDXD library for the kernel DSA driver.
- Init library: Added Init library that initializes the SPDK subsystems.
- Userspace DTrace: Added support running bpftrace scripts against SPDK applications. See https://spdk.io/doc/usdt.html.
- zipf utility: Added zipf random number generator with power law probability distribution. When used with bdevperf and nvme perf tools - blocks over the full range of LBAs will be used, but will more frequently select lower-numbered LBAs.
