libtorrent-1.1.0

1.1.0 release

  posted regardless of alert mask
• improve DHT performance when changing external IP (primarily affects
  bootstrapping).
• add feature to stop torrents immediately after checking files is done
• make all non-auto managed torrents exempt from queuing logic, including
  checking torrents.
• add option to not proxy tracker connections through proxy
• removed sparse-regions feature
• support using 0 disk threads (to perform disk I/O in network thread)
• removed deprecated handle_alert template
• enable logging build config by default (but alert mask disabled by default)
• deprecated RSS API
• experimental support for BEP 38, "mutable torrents"
• replaced lazy_bdecode with a new bdecoder that's a lot more efficient
• deprecate time functions, expose typedefs of boost::chrono in the
  libtorrent namespace instead
• deprecate file_base feature in file_storage/torrent_info
• improve piece picker support for reverse picking (used for snubbed peers)
  to not cause priority inversion for regular peers
• improve piece picker to better support torrents with very large pieces
  and web seeds. (request large contiguous ranges, but not necessarily a
  whole piece).
• deprecated session_status and session::status() in favor of performance
  counters.
• improve support for HTTP where one direction of the socket is shut down.
• remove internal fields from web_seed_entry
• separate crypto library configuration and whether to support
  bittorrent protocol encryption
• simplify bittorrent protocol encryption by just using internal RC4
  implementation.
• optimize copying torrent_info and file_storage objects
• cancel non-critical DNS lookups when shutting down, to cut down on
  shutdown delay.
• greatly simplify the debug logging infrastructure. logs are now delivered
  as alerts, and log level is controlled by the alert mask.
• removed auto_expand_choker. use rate_based_choker instead
• optimize UDP tracker packet handling
• support SSL over uTP connections
• support web seeds that resolve to multiple IPs
• added auto-sequential feature. download well-seeded torrents in-order
• removed built-in GeoIP support (this functionality is orthogonal to
  libtorrent)
• deprecate proxy settings in favor of regular settings
• deprecate separate settings for peer protocol encryption
• support specifying listen interfaces and outgoing interfaces as device
  names (eth0, en2, tun0 etc.)
• support for using purgrable memory as disk cache on Mac OS.
• be more aggressive in corking sockets, to coalesce messages into larger
  packets.
• pre-emptively unchoke peers to save one round-trip at connection start-up.
• add session constructor overload that takes a settings_pack
• torrent_info is no longer an intrusive_ptr type. It is held by shared_ptr.
  This is a non-backwards compatible change
• move listen interface and port to the settings
• move use_interfaces() to be a setting
• extend storage interface to allow deferred flushing and flush the part-file
  metadata periodically
• make statistics propagate instantly rather than on the second tick
• support for partfiles, where partial pieces belonging to skipped files are
  put
• support using multiple threads for socket operations (especially useful for
  high performance SSL connections)
• allow setting rate limits for arbitrary peer groups. Generalizes
  per-torrent rate limits, and local peer limits
• improved disk cache complexity O(1) instead of O(log(n))
• add feature to allow storing disk cache blocks in an mmapped file
  (presumably on an SSD)
• optimize peer connection distribution logic across torrents to scale
  better with many torrents
• replaced std::map with boost::unordered_map for torrent list, to scale
  better with many torrents
• optimized piece picker
• optimized disk cache
• optimized .torrent file parsing
• optimized initialization of storage when adding a torrent

  performance)
