* some timer optimizations
* removed the reuse-address flag on the listen socket
* fixed bug where local peer discovery and DHT wouldn't be announced to without trackers
* fixed bug in bdecoder when decoding invalid messages
* added build warning when building with UNICODE but the standard library
doesn't provide std::wstring
* fixed add_node python binding
* fixed issue where trackers wouldn't tried immediately when the previous one failed
* fixed synchronization issue between download queue and piece picker
* fixed bug in udp tracker scrape response parsing
* fixed bug in the disk thread that could get triggered under heavy load
* fixed bug in add_piece() that would trigger asserts
* fixed vs 2010 build
* recognizes more clients in identify_client()
* fixed bug where trackers wouldn't be retried if they failed
* slight performance fix in disk elevator algorithm
* fixed potential issue where a piece could be checked twice
* fixed build issue on windows related to GetCompressedSize()
* fixed deadlock when starting torrents with certain invalid tracker URLs
* fixed iterator bug in disk I/O thread
* fixed FIEMAP support on linux
* fixed strict aliasing warning on gcc
* fixed inconsistency when creating torrents with symlinks
* properly detect windows version to initialize half-open connection limit
* fixed bug in url encoder where $ would not be encoded
0.15 release
* introduced a session state save mechanism. load_state() and save_state().
this saves all session settings and state (except torrents)
* deprecated dht_state functions and merged it with the session state
* added support for multiple trackers in magnet links
* added support for explicitly flushing the disk cache
* added torrent priority to affect bandwidth allocation for its peers
* reduced the number of floating point operations (to better support
systems without FPU)
* added new alert when individual files complete
* added support for storing symbolic links in .torrent files
* added support for uTorrent interpretation of multi-tracker torrents
* handle torrents with duplicate filenames
* piece timeouts are adjusted to download rate limits
* encodes urls in torrent files that needs to be encoded
* fixed not passing &supportcrypto=1 when encryption is disabled
* introduced an upload mode, which torrents are switched into when
it hits a disk write error, instead of stopping the torrent.
this lets libtorrent keep uploading the parts it has when it
encounters a disk-full error for instance
* improved disk error handling and expanded use of error_code in
error reporting. added a bandwidth state, bw_disk, when waiting
for the disk io thread to catch up writing buffers
* improved read cache memory efficiency
* added another cache flush algorithm to write the largest
contiguous blocks instead of the least recently used
* introduced a mechanism to be lighter on the disk when checking torrents
* applied temporary memory storage optimization to when checking
a torrent as well
* removed hash_for_slot() from storage_interface. It is now implemented
by using the readv() function from the storage implementation
* improved IPv6 support by announcing twice when necessary
* added feature to set a separate global rate limit for local peers
* added preset settings for low memory environments and seed machines
min_memory_usage() and high_performance_seeder()
* optimized overall memory usage for DHT nodes and requests, peer
entries and disk buffers
* change in API for block_info in partial_piece_info, instead of
accessing 'peer', call 'peer()'
* added support for fully automatic unchoker (no need to specify
number of upload slots). This is on by default
* added support for changing socket buffer sizes through
session_settings
* added support for merkle hash tree torrents (.merkle.torrent)
* added 'seed mode', which assumes that all files are complete
and checks hashes lazily, as blocks are requested
* added new extension for file attributes (executable and hidden)
* added support for unbuffered I/O for aligned files
* added workaround for sparse file issue on Windows Vista
* added new lt_trackers extension to exchange trackers between
peers
* added support for BEP 17 http seeds
* added read_piece() to read pieces from torrent storage
* added option for udp tracker preference
* added super seeding
* added add_piece() function to inject data from external sources
* add_tracker() function added to torrent_handle
* if there is no working tracker, current_tracker is the
tracker that is currently being tried
