dnscrypt-proxy 2.0.22 has just been released, fixing a caching but that was introduced in version
But probably more interesting is a new technology that is likely to be part of the next major release: Stretch-Hash-and-Truncate.
Stretch-Hash-and-Truncate (SH&T) is a novel technique to drastically increase DNS privacy. It can work over DNS-over-HTTPS, but requires a specifically configured server.
A preliminary implementation has been merged to the development tree for testing: https://github.com/jedisct1/dnscrypt-proxy/commit/2d1dd7eaabc93d6d8669d3eaa05a759417e0c56b
Hoping to see Cloudflare deploy this technology on their servers soon.
