This is a big one fellas.
This release fixes a nasty bug where Applications files were not being shared (relief)
The Peer list is now ordered by distance (closer peers appear on top, you should be always on top), other peers that don’t say where they are go towards the bottom sorted alphabetically.
4 nasty crashes were fixed.
Spanish Support. More translations are coming in further releases.
We added back the “Search” button to search since Android’s keyboards tend to behave differently and lots of people complained about not having an explicit Search button.

I really think you should update the user interface for the pc version. Im getting kind of tired of the same old boring low tech interface.
UI upgrades coming this year, promised.
how can i sync music from frostwire to my phone?
If you have an Android phone, install FrostWire on it, and have it connected to the same Wi-Fi network as your computer. You will be able to transfer files From FrostWire for Desktop to your phone very easily from Within FrostWire.
Otherwise, you’ll just have to connect your phone to your computer via USB and transfer files to your phone, FrostWire doesn’t do this, but your phone and your operating system should allow you to do so.
