Remember that installing SharpCap 3.1 will not uninstall SharpCap 3.0 (or other earlier versions). This means that you can go back to an earlier version if you encounter any problems (do remember to report any problems you find though!)

The SharpCap 3.1 Beta is now over – however you can still find the list of builds and changes this page.

You can find very old versions of SharpCap here.
