Today we are ready to ship to you an updated version of Skype 4.0 Beta 3 for Windows.

With this update we have included some features from Skype 3.8 for Windows which have not yet been part of the 4.0 series. In addition we have added an option to disable uPnp and Nat-PMP port mapping, because some of our users were asking for it.

That's not all. Starting from this version we've included the new Super Wideband Audio codec. This is our second in-house built audio codec especially designed for calls over the internet with superb quality. The Super Wideband Audio codec will help you most on lousy network conditions and when you have lower bandwidth available, although it also improves quality in normal conditions too.

We recommend that everyone who is already using 4.0 beta versions to upgrade to this build and welcome everyone else to try out this new version.

You can download the 4.0 beta 3 hotfix from here. Please keep in mind that it is still a beta version which might have some mysteries hidden under the surface.

Please let us know if you happen to be the lucky finder of any hidden mysteries . You can inform us about problems in our public issue tracker. You are also welcomed to discuss things on Skype Community or just leave us a note on our feedback page.
