We've just posted the LimeWire 3.4.0 beta on both the free download page and the pro download page. The pro download is available from your pro download page, and the free download is available at:
http://www.limewire.com/english/content/beta.shtml
3.4.0 adds a new "find more sources" button that will search for more sources fo r your download if your download fails. If LimeWire locates more sources for the same exact file you were downloading, it will automatically resume the download.
3.4.0 also fixes a number of bugs from previous versions.
As always, thanks very much for everyone's help testing the betas!
