For those people who follow my blog/Twitter: TCPRelay 0.3 alpha 3 is now available! Check out the original post for version 0.3 and download the 32-bit or 64-bit version. You may also need to install the Microsoft .NET Framework 4. Keep in mind that this is an alpha version; some features may not behave correctly.
There were two changes to the GUI:
NEW: [alpha 3] application now has an icon (thanks to Fryderyk "Ziel" Dachowski!)
FIXED: [alpha 3] tooltips for speed buttons were incorrectly referring to "as slow as possible".
