* Version 2.0.7
 - Bug fix: optional ports were not properly parsed with IPv6
addresses -- thanks to @bleeee for the report and fix.
 - Bug fix: truncate TCP queries to the prefixed length.
 - Certificates are force-refreshed after a time jump (e.g. when a
system resumes from hibernation).

* Version 2.0.6
 - Automatic log files rotation was finally implemented.
 - A new -pidfile command-line option to write the PID file was added.

* Version 2.0.5
 - Fixes a crash occasionally happening when using DoH servers, with
stamps not containing any IP addresses, a DNSSEC-signed name, a
non-working system DNS configuration, and a fallback server supporting
DNSSEC.

* Version 2.0.4
 - Fixes a regression with truncated packets. Thanks to @mazesy and
@the-w1nd for spotting a case triggering this!

* Version 2.0.3
 - Load balancing: resolvers that respond promptly, but with bogus
responses are now gradually removed from the preferred pool.
 - Due to popular request, Android binaries are now available! Thanks
to @sporif for his help on getting these built.
 - Binaries are built using Go 1.10-final.

* Version 2.0.2
 - Properly error out on FreeBSD and other platforms where built-in
service installation is not supported yet.
 - Improved load-balancing algorithm, which should result in lower
latency.

* Version 2.0.1
 - Cached source data were not redownloaded if the proxy was used
without interruption. This has been fixed.
 - If the network is down at startup time, fall back to cached source
data, even if is it out of date, and schedule an immediate update
after the networks is back.
 - RTT estimation for DNS-over-HTTP/2 servers was off. This has been
fixed.
 - The generate-domains-blacklist script now has a configurable
timeout value, and can produce time-based rules.
 - The timeout parameter in the example configuration file didn't had
the correct name; this has been fixed.
 - Cache: TTLs are now decreasing.
