* Version 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.
|
|
* Version 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.
|
|
* Version 2.0.33
- Fixes an issue that caused some valid queries to return `PARSE_ERROR`.
* Version 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.

* Version 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.
* Version 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 VinÃcius Zavam,
and fixed by Will Elwood, thanks!
* Version 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.

* Version 2.0.28
- Invalid server entries are now skipped instead of preventing a
source from being used. Thanks to Alison Winters for the contribution!
- Truncated responses are immediately retried over TCP instead of
waiting for the client to retry. This reduces the latency for large
responses.
- Responses sent to the local network are assumed to support at least
1252 bytes packets, and use optional information from EDNS up to 4096
bytes. This also reduces latency.
- Logging improvements: servers are not logged for cached, synthetic
and cloaked responses. And the forwarder is logged instead of the
regular server for forwarded responses.

* Version 2.0.27
- The X25519 implementation was changed from using the Go standard
implementation to using Cloudflare's CIRCL library. Unfortunately,
CIRCL appears to be broken on big-endian systems. That change has been
reverted.
- All the dependencies have been updated.
* Version 2.0.26
- A new plugin was added to prevent Firefox from bypassing the system
DNS settings.
- New configuration parameter to set how to respond to blocked
queries: `blocked_query_response`. Responses can now be empty record
sets, REFUSED response codes, or predefined IPv4 and/or IPv6 addresses.
- The `refused_code_in_responses` and `blocked_query_response` options
have been folded into a new `blocked_query_response` option.
- The fallback resolver is now accessed using TCP if `force_tcp` has
been set to `true`.
- CPU usage when enabling DNSCrypt ephemeral keys has been reduced.
- New command-line option: `-show-certs` to print DoH certificate
hashes.
- Solaris packages are now provided.
- DoH servers on a non-standard port, with stamps that don't include
IP addresses, and without working system resolvers can now be properly
bootstrapped.
- A new option, `query_meta`, is now available to add optional records
to client queries.

* Version 2.0.25
- The example IP address for network probes didn't work on Windows.
The example configuration file has been updated and the fallback
resolver IP is now used when no netprobe address has been configured.
* Version 2.0.24
- The query log now includes the time it took to complete the
transaction, the name of the resolver that sent the response and if
the response was served from the cache. Thanks to Ferdinand Holzer for
his help!
- The list of resolvers, sorted by latency, is now printed after all
the resolvers have been probed.
- The "fastest" load-balancing strategy has been renamed to "first".
- On Windows, a nul byte is sent to the netprobe address. This is
required to check for connectivity on this platform. Thanks to Mathias
Berchtold.
- The Malwaredomainlist URL was updated to directly parse the host
list. Thanks to Encrypted.Town.
- The Python script to generate lists of blacklisted domains is now
compatible both with Python 2 and Python 3. Thanks to Simon R.
- A warning is now displayed for DoH is requested but the server
doesn't speak HTTP/2.
- A crash with loaded-balanced sets of cloaked names was fixed.
Thanks to @inkblotadmirer for the report.
- Resolvers are now tried in random order to avoid favoring the first
ones at startup.

Changes since 2.0.22:
- .onion servers are now automatically ignored if Tor routing is not
enabled.
- Caching of server addresses has been improved, especially when
using proxies.
- DNSCrypt communications are now automatically forced to using TCP
when a SOCKS proxy has been set up.

The previous version had issues with the .org TLD when used in conjunction with dnsmasq.
This has been fixed.

|
* Startup is now way faster, especially when using DoH servers.
* A new action: CLOAK is logged when queries are being cloaked.
* A cloaking rule can now map to multiple IPv4 and IPv6 addresses, with load-balancing.
* New option: refused_code_in_responses to return (or not) a REFUSED code on blacklisted queries. This is disabled by default, in order to work around a bug in Android Pie.
* Time-based restrictions are now properly handled in the generate-domains-blacklist.py script.
* Other improvements have been made to the generate-domains-blacklist.py script.
* The Windows service is now installed as NT AUTHORITY\NetworkService.

Changelog:
* The value for netprobe_timeout was read from the command-line, but not from the configuration file any more. This is a regression introduced in the previous version, that has been fixed.
* The default value for netprobe timeouts has been raised to 60 seconds.
* A hash of the body is added to query parameters when sending DoH queries with the POST method in order to work around badly configured proxies.
|
|
* Version 2.0.18
- Official builds now support TLS 1.3.
- The timeout for the initial connectivity check can now be set from
the command line.
- An `Accept:` header is now always sent with `GET` queries.
- BOMs are now ignored in configuration files.
- In addition to SOCKS, HTTP and HTTPS proxies are now supported for
DoH servers.

Changes:
* Go >= 1.11 is now supported
* When dropping privileges, there is no supervisor process any more.
* DNS options used to be cleared from DNS queries, with the exception of flags and payload sizes. This is not the case any more.
* DoH queries are smaller, since workarounds are not required any more after Google updated their implementation.

Changes:
- On Unix-like systems, the server can run as an unprivileged user,
and the main process will automatically restart if an error occurs.
- pledge() on OpenBSD.
- New "offline" mode to serve queries locally without contacting any
upstream servers. This can be especially useful along with the
cloaking module for local development.
- New logo.
- TTL of OPT records is properly ignored by the caching module.
- The proxy doesn't quit any more if new TCP connections cannot be
created.
