Faster downloads: We have switched from the old python based bittorrent core to Rasterbar's libtorrent, so expect less resource usage too, we are saturating a symmetric 100Mb/s connection without much trouble.
Less disk and CPU consumption used for community synchronization.
UI improvements (download speed graphs, some new icons, general UI cleanup...)
Throttling (Bandwidth limitation) is working again.
The LibSwift engine has been updated too.
The "Save as" dialog has been modified to improve usability when downloading from magnet links.
Thumbnails for downloaded media: Now when a new video file gets downloaded, Tribler will automatically create a thumbnail and make it available to the rest of peers to be shown on the search results for all the media you download from your favourite open channels.
Fixed freezing at startup on some machines.
Fixed race conditions and lockups in synchronizations.
Various bug fixes and minor improvements.
Fixes for the bugs reported by the community during beta1 and beta2 (Thanks!)
