-Version 1.1pre2              Juli 17 2011
+Version 1.1pre3              October 14 2012
+
+ * New experimental protocol:
+   * Uses 521 bit ECDSA keys for authentication.
+   * Uses AES-256-CTR and HMAC-SHA256.
+   * Always provides perfect forward secrecy.
+   * Used for both meta-connections and VPN packets.
+   * VPN packets are encrypted end-to-end.
+
+ * Many improvements to tincctl:
+   * "config" command shows/adds/changes configuration variables.
+   * "export" and "import" commands help exchange configuration files.
+   * "init" command sets up initial configuration files.
+   * "info" command shows details about a node, subnet or address.
+   * "log" command shows live log messages.
+   * Without a command it acts as a shell, with history and TAB completion.
+   * Improved starting/stopping tincd.
+   * Improved graph output.
+
+ * When trying to directly send UDP packets to a node for which multiple
+   addresses are known, all of them are tried.
+
+ * Many small fixes, code cleanups and documentation updates.
+
+Version 1.1pre2              July 17 2011
 
  * .cookie files are renamed to .pid files, which are compatible with 1.0.x.

 Features
 --------
 
-This version of tinc supports multiple virtual networks at once. To
-use this feature, you may supply a netname via the -n or --net
-options. The standard locations for the config files will then be
-/etc/tinc/<net>/.
-
-tincd regenerates its encryption key pairs. It does this on the first
-activity after the keys have expired. This period is adjustable in the
-configuration file, and the default time is 3600 seconds (one hour).
-
-This version supports multiple subnets at once. They are also sorted
-on subnet mask size. This means that it is possible to have
-overlapping subnets on the VPN, as long as their subnet mask sizes
-differ.
-
-Since pre5, tinc can operate in several routing modes. The default mode,
-"router", works exactly like the older version, and uses Subnet lines to
-determine the destination of packets. The other two modes, "switch" and "hub",
-allow the tinc daemons to work together like a single network switch or hub.
-This is useful for bridging networks. The latter modes only work properly on
-Linux, FreeBSD and Windows.
-
-The algorithms used for encryption and generating message authentication codes
-can now be changed in the configuration files. All cipher and digest algorithms
-supported by OpenSSL can be used. Useful ciphers are "blowfish" (default),
-"bf-ofb", "des", "des3", etcetera. Useful digests are "sha1" (default), "md5",
-etcetera.
-
-Support for routing IPv6 packets has been added. Just add Subnet lines with
-IPv6 addresses (without using :: abbreviations) and use ifconfig or ip (from
-the iproute package) to give the virtual network interface corresponding IPv6
-addresses. tinc does not provide autoconfiguration for IPv6 hosts, if you need
-it use radvd or zebra.
-
-It is also possible to make tunnels to other tinc daemons over IPv6 networks,
-if the operating system supports IPv6.  tinc will automatically use both IPv6
-and IPv4 when available, but this can be changed by adding the option
-"AddressFamily = ipv4" or "AddressFamily = ipv6" to the tinc.conf file.
+Tinc is a peer-to-peer VPN daemon that supports VPNs with an arbitrary number
+of nodes. Instead of configuring tunnels, you give tinc the location and
+public key of a few nodes in the VPN. After making the initial connections to
+those nodes, tinc will learn about all other nodes on the VPN, and will make
+connections automatically. When direct connections are not possible, data will
+be forwarded by intermediate nodes.
+
+By default, nodes authenticate each other using 2048 bit RSA (or 521 bit
+ECDSA*) keys. Traffic is encrypted using Blowfish in CBC mode (or AES-256 in
+CTR mode*), authenticated using HMAC-SHA1 (or HMAC-SHA-256*), and is protected
+against replay attacks.
+
+*) When using the ExperimentalProtocol option.
+
+Tinc fully supports IPv6.
+
+Tinc can operate in several routing modes. In the default mode, "router", every
+node is associated with one or more IPv4 and/or IPv6 Subnets. The other two
+modes, "switch" and "hub", let the tinc daemons work together to form a virtual
+Ethernet network switch or hub.
 
 Normally, when started tinc will detach and run in the background. In a native
 Windows environment this means tinc will intall itself as a service, which will
 restart after reboots.  To prevent tinc from detaching or running as a service,
 use the -D option.
 
+The status of the VPN can be queried using the "tincctl" tool, which connects
+to a running tinc daemon via a control connection. The same tool also makes it
+easy to start and stop tinc, and to change its configuration.
