VERSION 0.8.2

This version fixes a few more issues with TCP tunneling including GitHub issue #63. It also adds automatic announcement and location of peers on physical LANs (GitHub issue #56) which should greatly improve performance if you happen to be on the same LAN or WiFi network as another peer. It can take 60 seconds or so for this to occur, but it should.
More toward GitHub issue #56

+To build the UI you will need Qt version 5.0 or later. The Qt home must
+be symbolically linked into "Qt" in the parent directory of the ZeroTier

+You can also load the UI in Qt Creator and build/test it that way.

 ZeroTier One creates flat virtual Ethernet networks of almost unlimited size. [Visit ZeroTier Networks on the web](https://www.zerotier.com/) for more information.

-This project is now in beta, which means that major incompatible protocol shifts should now become considerably more rare. You should still update very often if you plan to use it. Binary packages with auto-update are coming very soon.
-
 Follow the [ZeroTier blog](http://blog.zerotier.com/) and the [GitHub project](https://github.com/zerotier/ZeroTierOne) to stay up to date.

-See BUILDING.txt and RUNNING.txt for instructions. It currently runs on Mac and Linux. A Windows port is well along the way to completion. If you're brave you can load the Visual Studio 2012 solution and play around.
+Auto-updating binary packages that install easily [can be found here.](https://www.zerotier.com/download.html) If you want to build from source, clone this repository and see BUILDING.txt and RUNNING.txt.

-Once you have it running you can join the Earth network -- a LAN for the planet -- by using the 'zerotier-cli' tool: 'sudo zerotier-cli join 8056c2e21c000001'. Right now Earth is the only network. Ability to create private networks, as well as some additional special-purpose public ones, will be coming soon. (Note: previous alpha versions auto-joined Earth, but since 0.5.0 it no longer does this.)
+Once you are up and running, you can [create an account on the network control panel](https://www.zerotier.com/networks.html) if you want to create a private network or you can join [Earth](https://www.zerotier.com/earth.html) by running (on Linux and Mac) `sudo ./zerotier-cli join 8056c2e21c000001`.

 Note that this won't work if your firewall does not allow outbound UDP. It must allow two way UDP conversations on port 9993 at a minimum.
