* require C++11 to build libtorrent
* document deprecation of dynamic loading/unloading of torrents
* include user-agent in tracker announces in anonymous_mode for private torrents
* add support for IPv6 peers from udp trackers
* correctly URL encode the IPv6 argument to trackers
* fix default file pool size on windows
* fix bug where settings_pack::file_pool_size setting was not being honored
* add feature to periodically close files (to make windows clear disk cache)
* fix bug in torrent_handle::file_status
