2.0.36-beta.1

• New option: block_undelegated. When enabled, dnscrypt-proxy will directly respond to queries for locally-served zones (https://sk.tl/2QqB971U) and nonexistent zones that should have been kept local, but are frequently leaked. This reduces latency and improves privacy.
• Conformance: the DO bit is now set in synthetic responses if it was set in a question, and the AD bit is cleared.
• The miegkg/dns module was updated to version 1.1.25, that fixes a security issue affecting non-encrypted/non-authenticated DNS traffic. In dnscrypt-proxy, this only affects the forwarding feature.

There have also been quite a bit of internal changes, so please report any possible regression!

2.0.35

• New option: block_unqualified to block A/AAAA queries with unqualified host names. These will very rarely get an answer from upstream resolvers, but can leak private information to these, as well as to root servers.
• When a CNAME pointer is blocked, the original query name is now logged along with the pointer. This makes it easier to know what the original query name, so it can be whitelisted, or what the pointer was, so it can be removed from the blacklist.

2.0.34

• Blacklisted names are now also blocked if they appear in CNAME pointers.
• dnscrypt-proxy can now act as a local DoH server. Firefox can be configured to use it, so that ESNI can be enabled without bypassing your DNS proxy.

2.0.34-beta.1

• Blacklisted names are now also blocked if they appear in CNAME pointers.
• dnscrypt-proxy can now act as a local DoH server. Firefox can be configured to use it, so that ESNI can be enabled without bypassing your DNS proxy.

2.0.33

Fixes an issue that caused some valid queries to return PARSE_ERROR.

2.0.32

• On certificate errors, the server name is now logged instead of the provider name, which is generally more useful.
• IP addresses for DoH servers that require DNS lookups are now cached for at least 12 hours.
• ignore_system_dns is now set to true by default.
• A workaround for a bug in Cisco servers has been implemented.
• A corrupted or incomplete resolvers list is now ignored, keeping the last good known cached list until the next update. In addition, logging was improved and unit tests were also added. Awesome contribution from William Elwood, thanks!
• On Windows, the network probe immediately returned instead of blocking if netprobe_timeout was set to -1. This has been fixed.
• Expired cached IP addresses now have a grace period, to avoid breaking the service if they temporarily can't be refreshed.
• On Windows, the service now returns immediately, solving a long-standing issue when initialization took more than 30 seconds ("The service did not respond to the start or control request in a timely fashion"). Fantastic work by Alison Winters, thanks!
• The SERVER_ERROR error code has been split into two new error codes: NETWORK_ERROR (self-explanatory) and SERVFAIL (a response was returned, but it includes a SERVFAIL error code).
• Responses are now always compressed.

2.0.31

• This version fixes two regressions introduced in version 2.0.29: DoH server couldn't be reached over IPv6 any more, and the proxy couldn't be interrupted while servers were being benchmarked.

2.0.30

• This version fixes a startup issue introduced in version 2.0.29, on systems for which the service cannot be automatically installed (such as OpenBSD and FreeBSD). Reported by @5ch17 and Vinícius Zavam, and fixed by Will Elwood, thanks!

2.0.29

• Support for Anonymized DNS has been added!
• Wait before stopping, fixing an issue with Unbound (thanks to Vladimir Bauer)
• DNS stamps are now included in the -list-all -json ouptut
• The netprobe_timeout setting from the configuration file or command-line was ignored. This has been fixed.
• The TTL or cloaked entries can now be adjusted (thanks to Markus Linnala)
• Cached IP address from DoH servers now expire (thanks to Markus Linnala)
• DNSCrypt certificates can be fetched over Tor and SOCKS proxies
• Retries over TCP are faster
• Improved logging (thanks to Alison Winters)
• Ignore non-TXT records in certificate responses (thanks to Vladimir Bauer)
• A lot of internal cleanups, thanks to Markus Linnala

2.0.29-beta.3

• Improved logging
• Added a workaround for DNS servers using a non-standard provider name.
