* New listview for uploads and downloads view. Those should ease CPU usage a lot when expanding downloads with many sources.
* Better keyboard focus handling throughout the app: the downloads, uploads, search and library views now set keyboard focus to their primary list (or search box) when the tab or window is activted.
* Optimized piece picker for BitTorrent
* Optimized BitTorrent "Show interest" algorithm
* Optimized ed2k fragment selector
* Optimized verification selector
* Sending "extended requests" instead of standard ones to eDonkey2000 download sources.
* Fixed a bug where exporting a collection based on a virtual folder with no metadata would crash.
