We've gotten a lot of requests for better support for AMD processors (Athlon II, Phenom, FX, etc.), and we deliver in this version. This involved rewriting the parts of our code which used SSSE3, SSE4.1 to only use SSE2. The rewrite actually helped us increase performance overall (even on Intel Core i7 processors). We're pretty happy with the result and encourage you to try out our latest version!
Another improvement in this version is a smoother installation process. For people who don't have administrative access on their machines, this version is a big deal. Now, once our software has been installed, it can be configured and run by any user on the local machine without permission issues or stomping on someone else's data.
As always, you can grab our latest version from our download page.
