* Version 1.9.1
 - The blocking plugin introduced in version 1.9.0 didn't properly
handle overlapping rules. This has been fixed.
 - The documentation and examples were updated.
 - The mimimum time to keep a record in cache can be specified in the
cache plugin, with the `--with-ttl` option (config file: `with-ttl:...`).
 - The example generate-domains-blacklist.py script produces a more
optimized list, without overlapping names.

* Version 1.9.0
 - Support for TCP was added to the `hostip` tool.
 - New plugin: `example-ldns-forwarding`. This plugin forwards queries for
a specific set of domain names to one or more non-DNSCrypt resolvers.
This can be used to send queries for private domains to the router or
to an internal DNS server.
 - New plugin: `example-cache`. This plugin implements a simple,
zero-configuration DNS response cache.
 - The default plugin paths, as loaded via the configuration file, use
the native module file names instead of libtool's `.la` files. Installing the
`.la` files has now become optional.
 - Many changes and simplifications were made to the documentation.
 - `-Z` (syslog prefix) doesn't imply `-S` any more.
 - The `ResolverAddress` option can now be used even if a full
configuration was provided via `ResolverName` in order to override the
resolver IP and port.
 - A new `contrib` folder is born, and currently contains a Python
script to automatically generate a malware/spam/ads/tracker blacklist
from public lists. More contributions would be more than welcome!
 - Example startup scripts now use the configuration file.
 - A `SIGHUP` signal sent to the proxy now reloads all the plugins.
This can be used after a plugin configuration update, or to rotate the log
files.
 - `--ignore-timestamps` didn't work as expected. This has been fixed,
thanks to Toni Uhlig.
 - `make install` does not overwrite an existing `dnscrypt-proxy.conf`
file any more. An up-to-date example is installed as
`dnscrypt-proxy.conf.example`.
 - The query log and the logfile of hits for blacklisted domains/IPs
are now more detailed and more readable. As an alternative to human-readable
records, prefixing a log file name with "ltsv:" causes the log entries to use
the LTSV structured format. These logs can thus be easily sent to
Flowgger/ElasticSearch for visualization and reporting.
 - The domain/ip blocking plugin was completely rewritten, and is now
extremely fast even with very lasrge blacklists of names and IP addresses.
It can now be used to locally block malware/spam/ads/trackers and other
unwanted content, based on prefixes, suffixes and keywords.

* Version 1.8.1
 - Version 1.8.0 didn't use the same Windows registry key as past
versions. This has been fixed. In order to upgrade from 1.8.0,
it is recommended to uninstall the service before upgrading
(using the `dnscrypt-proxy --uninstall` command).
 - The SDK used to build Android binaries was downgraded in order to
retain compatibility with Android 4.1 (Jelly Bean).

* Version 1.8.0:
 - All the features of the proxy can now be enabled using a
configuration file.
 - On Windows, a new option, `--service-name` can be used to set the
service name, so that multiple instances can run simultaneously.
 - On Windows, `--install-with-config-file` can be used to install a
service using a configuration file.
 - The protocol can now use the XChaCha20 cipher as a faster alternative
to XSalsa20.
 - Time stamps are now being added to log files, including log files
from plugins.
 - `SIGINT` & `SIGTERM` handlers have been added to give plugins a chance
to call a teardown function.
 - A message is now displayed when servers are using a very long key
rotation period.
 - The domain blocking plugin is now a `pre_filter`: blocked queries are
not sent to upstream resolvers any more [breaking change for logging
resolvers].
 - The domain blocking plugin do not consider empty files an error any
more.
 - The domain blocking plugin has a new option (`--logfile`) to log
queries sent to blacklisted IPs and names.
 - Android's update-binary file is not part of the source distribution
any more.
 - libevent2 has been updated.
 - The resolvers list was updated to the latest version.
 - iOS builds now require iOS 6.0.0.
 - Windows builds now link ldns against LibreSSL.

* Version 1.7.0:
 - Plugins are now enabled by default.
 - Windows: new registry key: `LogFile`.
 - New command-line option: `--ignore-timestamps` to ignore timestamps
when performing certificate validation.
 - New command-line option: `--syslog-prefix` to add a prefix to log
messages.
 - Certificates can now be retrieved using TCP.
 - Libevent was updated to version 2.0.23.
 - Certificates serial numbers are printed as a string if possible.
 - The list of known public resolvers was updated.
 - Builds for Win64 are now available.

* Version 1.6.1:
 - Security: malformed packets could cause the OpenDNS deviceid,
OpenDNS set-client-ip, blocking and AAAA blocking plugins to use
uninitialized pointers, leading to a denial of service or possibly
code execution. The vulnerable code is present since dnscrypt-proxy
1.1.0. OpenDNS users and people using dnscrypt-proxy in order to block
domain names and IP addresses should upgrade as soon as possible.

* Version 1.6.0:
 - New feature: public-key based client authentication (-K), for
private and commercial DNS services to securely authenticate the
sender of a query no matter what the source IP address is, without
altering the DNS query.
 - On Windows, paths are now relative to the application folder. Which
means that the -L option is usually not required any more if the CSV
file is in the same folder as the dnscrypt-proxy executable. Full
paths to plugins are not required any more either; plugin names can be
given directly.

* Version 1.5.0:
 - New option: -E, to use an ephemeral key pair for each query.
 - Logging to files is supported on Windows.
 - TCP FASTOPEN is now enabled on Linux.

* Version 1.4.3:
 - libevent update, including a fix for CVE-2014-6272
 - Two new public dnscrypt resolvers were added: opennic-us-wa-ns1 and
dnscrypt.org-fr.
 - d0wn servers in France IP have changed.
 - Compilation fixes.

* Version 1.4.2:
 - New compilation switch: --with-systemd, to enable socket activation
support when using systemd.
 - The list of public DNSCrypt-enabled resolvers was updated.
 - Libevent2 updates.

* Version 1.4.1:
 - Alternative ports to dnscrypt.eu servers have been added
 - Android build scripts are now part of the package
 - UDP queries timing out are not retried any more. This caused some issues
and was already better handled by stub resolvers and caching name servers.

* Version 1.4.0:
 - Security: versions 0.11 to 1.3.3 were vulnerable to a denial of
service when running out of output buffer space. Reported by @iamultra.
 - Windows: --uninstall now actually stops the service
 - Windows: registry keys are automatically created for a given
provider when installing the service.
 - The resolver to use and its configuration can now be specified as a
definition file + the name of the resolver to use. The new
command-line options to use are --resolvers-list=<csv file> (optional
on non-Windows platforms) and --resolver-name=<name>. This deprecates
--provider-key, --provider-name and --resolver-address.
 - Documentation and diagnostics have been improved.

* Version 1.3.3:
 - Try to send questions as big as the response can be. Upgrading is
highly recommended, as the server can refuse to respond to queries using
UDP if the response is larger than the question.

* Version 1.3.2:
 - faster startup on iOS and Android
 - New command-line switch: --test, in order to check if a certificate can be
   used, with an optional time safety margin.
 - The package now includes an AppArmor profile, thanks to InsanityBit.
 - Plugins using ldns can now be compiled on Windows.

* Version 1.3.1:
 - dnscrypt-proxy doesn't ship its own, possibly outdated copy of libsodium
   any more, and always picks the system one instead.
 - Minor compilation improvements for iOS, Android and FreeBSD.

* Version 1.3.0:
 - The bundled NaCl library with only reference implementations has been
   replaced with libsodium, leading to significant performance improvements.
 - A new command-line switch, --loglevel, allows adjusting the log verbosity.

* Version 1.2.1:
 - Add support for certificates split into multiple TXT records.
   Contributed by Yecheng Fu, thanks!

* Version 1.2.0:
 - A pre-filter can now totally bypass the resolver and directly send a
   reply to the client.
 - A new example plugin has been shipped: ldns-aaaa-blocking. It
   directly sends an empty response to AAAA queries in order to
   significantly speed up lookups on hosts without IPv6 connectivity
   (but with clients still asking for AAAA records anyway).
 - Example plugins requiring ldns can be compiled on Windows.
 - Paths with a drive name are now recognized as absolute paths on
   Windows.

* Version 1.1.0:
 - dnscrypt-proxy can now use plugins in order to alter/inspect
   queries and responses before and after they are relayed.
   See README-PLUGINS.markdown for more information.
 - The default max payload size has been trimmed down to 1252 bytes
   for compatibility with some scary network setups.
 - The --local-port and --resolver-port options are gone for good.
   They had been deprecated for a while and were undocumented since
   version 1.0.
 - Multiple certificates are now properly handled.
 - Memory leaks have been fixed, a big bad use-after-free condition
   has been fixed, uninitialized variables have been initialized.
   Upgrading is recommended, especially on Windows.

* Version 1.0.1:
 - dnscrypt-proxy and hostip can now be compiled for Android and
   Solaris.
 - The proxy can now run as a Windows service. The new --install and
   --uninstall command-line switches can automatically register the proxy
   as a service. Startup options are read from the Windows registry.
   See the README-WINDOWS.markdown file for details.

* Version 1.0:
 - Autotools scripts have been improved.
 - 1.0.

* Version 0.12:
 - Datagrams are resent after running out of memory, or if the queue
   was full.
 - Missing compilation flags broke 0.11 on some Linux distributions.
   This has been fixed.

* Version 0.11:
 - A new tool, hostip, can resolve host names before dnscrypt-proxy is
   started. This should help resolving chicken-and-egg problems on
   routers, as reported by LanceThePants.
 - The --local-port and --resolver-port options have been deprecated.
   Please use --local-address=<ip>:<port> and
   --resolver-address=<ip>:<port> instead.
 - Improved stability on Win32.

* Version 0.10.1:
 - The daemon didn't start on some Linux distributions lacking the
   RANDOM_UUID sysctl. This has been fixed.
 - The config.guess files have been patched in order to run out of the
   box on Bitrig.

* Version 0.10:
 - Almost a complete rewrite, with libuv being replaced by libevent.
 - The max number of simultaneous queries is now global, not
   per-protocol.
 - As an insane amount of routers and ISPs are hijacking port 53, the default
   server port is now 443.
 - iOS binaries are now smaller.
 - More dtrace probes.

* Version 0.9.5:
 - Full IPv6 support.

* Version 0.9.4:
 - The --tcp-port option is gone. The resolver port can now be set
   with --resolver-port= and forcing use of TCP can be achieved with
   --tcp-only.
 - portage files for Gentoo have been added.
 - Libuv has been updated.

* Version 0.9.3:
 - Support for native Windows builds.
 - --daemonize has been fixed.

* Version 0.9.2:
 - Support for cross-compilation. In particular, the proxy can now
   compile and work on iOS.

* Version 0.9.1:
 - DNSCrypt should compile out of the box on DD-WRT and other
   uclibc-based systems.

* Version 0.9:
 - libuv has been updated.
 - Enhanced compatibility with non-Intel architectures.

* Version 0.8:
 - Support for Windows (through Cygwin, for now) has been improved.
 - Documentation has been improved.
 - The package now compiles on Dragonfly BSD-current.
 - Signatures are now using ed25519 instead of edwards25519sha512batch.
 - The proxy now compiles on Openwall Linux.
 - Libuv has been updated.
 - A sample .plist file and a Homebrew formula for OSX are now provided.

* Version 0.7:
