Users can now use web proxies to route their downloads to protect their identity. Searches in LimeWire now immediately display information that fully describes files. Users can browse the network for the most recent content additions. LimeWire now recognizes OGGs and MP3s licensed under a Creative Commons License. Windows and Mac users can now take advantage of LimeWire's iTunes integration.
UPnP support allows LimeWire to find more search results and have faster downloads. Using new 'UDP Host Caches', LimeWire starts up and connects faster than ever before!
Since about 60% of users are currently firewalled, this feature greatly increases the amount of content on the network.
