The GitHub repository for dnscrypt-proxy was simply moved from my personal GitHub account to the DNSCrypt organization. GitHub automatically adds redirections when a project is moved, so this should be transparent.
dnscrypt-proxy 2 is actively supported since it was released in January 2018. What has been EOL'd is the legacy dnscrypt-proxy 1.x client, after having been supported for 7 years.
The protocol itself is also still evolving, with the recent introduction of a lightweight alternative to Tor in order to hide IP addresses: https://raw.githubusercontent.com/DNSCrypt/dnscrypt-protocol...
Besides the main website https://dnscrypt.info, there is a subreddit for announcements: https://www.reddit.com/r/dnscrypt/
I normally use WireGuard and use a DNS server supplied by that. If WireGuard is offline, I automatically use DNSCrypt.
Been using it for years, but did not know of the recent episode. Leaves you wondering..
Last month or so, the main GitHub repo for DNSCrypt randomly got deleted. It wasn't until several days later, the author posted a tweet saying he/she are not supporting it anymore.
Now it has seemingly been resurrected...after I have already configured my server to use a new project called getdns (and stubby).
