We've just posted the LimeWire 3.5.1 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:

3.5.1 adds many new features to improve your searching and downloading experience. These changes include:
- iTunes integration on OSX. When an audio download finishes, it will automatically be added to a 'LimeWire' playlist in iTunes.
- Easier bug reporting. You can now help us debug by simply clicking 'Send' when an internal error occurs. You still have the option to review the information before it is sent.
- Better validation on extra download sources, ultimately saving bandwidth and improving download success rates.
- Stalled downloads will now correctly die, allowing other sources to finish the download.
- More sources in search results.
- More aggressive download behaviour. LimeWire will now always attempt to find an active downloader, even if you're waiting in line from some hosts.
- More options for search results, downloads, uploads, connections and the library. By right-clicking (or control-click on macs) on the column headers of tables, you can choose to whether or not you want to display tooltips or row stripes, or if you want that table to be sorted automatically (automatic sorting is currently not available in search results).

Numerous bugs are also fixed.

As always, thanks very much for everyone's help testing the betas!
