The current download, PRO or Free, is LimeWire 4.4.0. (I'm not sure where this extra 1 got tacked on.)

The websites say 4.2 because we haven't updated them yet. I'm not positive if FileFront has updated their downloads to use 4.4 for OSX & Linux or if they're still giving 4.2.

When we update the website, everything will be in order. For now, consider it a sneak preview.
