     getdns_get_suffix(). Thanks Jim Hague
   * Better README.md.  Thanks Andrew Sullivan
 
+* 2016-10-19: Version 1.1.0-a2
+  * Improved TLS connection management
+  * OpenSSL 1.1 support
+  * Stubby, Server version of getdns_query that by default listens
+    on 127.0.0.1 and ::1 and reads config from /etc/stubby.conf
+    and $HOME/.stubby.conf
+
+* 2016-07-14: Version 1.1.0a1
+  * Conversion functions from text strings to getdns native types:
+    getdns_str2dict(), getdns_str2list(), getdns_str2bindata() and
+    getdns_str2int()
+  * A getdns_context_config() function that configures a context
+    with settings given in a getdns_dict
+  * A a getdns_context_set_listen_addresses() function and companion
+    getdns_reply() function to construct simple name servers.
+  * Relocate getdns_query to src/tools and build by default
+  * Enhancements to the logic used to select connection based upstream
+    transports (TCP, TLS) to improve robustness and re-use of
+    connections/upstreams.
+
 * 2016-07-14: Version 1.0.0b2
   * Collect coverage information from the unit tests
     Thanks Shane Kerr

@@ -19,6 +19,8 @@ Traditional access to DNS data from applications has several limitations:
 
 * Sophisticated uses of the DNS (things like IDNA and DNSSEC validation) require considerable application work, possibly by application developers with little experience with the vagaries of DNS.
 
+getdns also provides a experimental DNS Privacy enabled client called 'stubby' - see below for more details.
+
 ## Motivation for providing the API
 
 The developers are of the opinion that DNSSEC offers a unique global infrastructure for establishing and enhancing cryptographic trust relations.  With the development of this API we intend to offer application developers a modern and flexible interface that enables end-to-end trust in the DNS architecture, and which will inspire application developers to implement innovative security solutions in their applications.

+## Stubby
+
+* Stubby is an experimental implementation of a DNS Privacy enabled stub resolver. It is currently suitable for advanced/technical users - all feedback is welcome! Also see [dnsprivacy.org](https://dnsprivacy.org) for more information on DNS Privacy and stubby.
+* By default stubby will attempt to use 'Opportunistic' Privacy for DNS queries.
+* A sample configuration file is available in the source code (src/tools/stubby.conf) which uses 'Strict' Privacy and some of the available test DNS Privacy servers to resolve queries. Note these servers are test servers that offer no service guarantees. The location of a configuration file can be specified with the '-C' flag
+* RECOMMENDED: Minimal logging output from Stubby is available  (e.g. which servers are used and connection level statistics) by also using the '--enable-debug-daemon' flag when running 'configure'.
+
+To use stubby
+* Start stubby from the command line
+* Test it by doing, for example, 'dig @127.0.0.1 www.example.com'
+* Alter the default DNS resolvers on your system to point at localhost (127.0.0.1, ::1)
