libtorrent-1.2.10

Fixes since last stable release:

• fix regression in python binding for move_storage()
• improve stat_file() performance on Windows
• fix issue with loading invalid torrents with only 0-sized files
• fix to avoid large stack allocations

libtorrent-2.0.0-RC3

Major changes since 2.0 RC2:

• restored backwards compatibility with info_hash fields (introducing the v2-compatible info_hash_t as "info_hashes" instead). This is a major fix to ease upgrade. This brings libtorrent 2.0 much closer to being fully source compatible with 1.2.x. The custom storage API is the main part whose API has changed.
• dropped dependency on iconv
• dropped deprecated wstring overloads of some functions
• merged change from 1.2.x to drop Unicode-licensed code (for Debian compatibility)
• the soname of the libtorrent library is "2.0" and will be . going forward.

libtorrent-1.2.9

1.2.9 released

• add macro TORRENT_CXX11_ABI for clients building with C++14 against
  libtorrent build with C++11
• refreshed m4 scripts for autotools
• removed deprecated wstring overloads on non-windows systems
• drop dependency on Unicode's ConvertUTF code (which had a license
  incompatible with Debian)
• fix bugs exposed on big-endian systems
• fix detection of hard-links not being supported by filesystem
• fixed resume data regression for seeds with prio 0 files

libtorrent-1.2.8

Changes since the previous stable release:

• validate UTF-8 encoding of client version strings from peers
• don't time out tracker announces as eagerly while resolving hostnames
• fix NAT-PMP shutdown issue
• improve hostname lookup by merging identical lookups
• fix network route enumeration for large routing tables
• fixed issue where pop_alerts() could return old, invalid alerts
• fix issue when receiving have-all message before the metadata
• don't leave lingering part files handles open
• disallow calling add_piece() during checking
• fix incorrect filename truncation at multi-byte character
• always announce listen port 1 when using a proxy

libtorrent-2.0.0-RC2

In this 2nd release candidate of libtorrent-2.0, a fair number of issues has been fixed in the 1.2.x branch and been merged into the 2.0 one.

One notable update is an overhaul of the documentation, a pre-release of it can be found here.

The updated changelog for libtorrent-2.0 is:

• deprecate set_file_hash() in torrent creator, as it's superceded by v2 torrents
• deprecate mutable access to info_section in torrent_info
• removed deprecated lazy_entry/lazy_bdecode
• stats_alert deprecated
• remove bittyrant choking algorithm
• update userdata in add_torrent_params to be type-safe and add to torrent_handle
• add ip_filter to session_params
• added support for wolfSSL for SHA-1 hash and HTTPS (no Torrents over SSL)
• requires OpenSSL minimum version 1.0.0 with SNI support
• deprecated save_state() and load_state() on session in favour of new
  write_session_params() and read_session_params()
• added support for BitTorrent v2 (see docs/upgrade_to_2.0.html)
• create_torrent() pad_file_limit parameter removed
• create_torrent() merkle- and optimize-alignment flags removed
• merkle_tree removed from add_torrent_params
• announce_entry expose information per v1 and v2 info-hash announces
• torrent_removed_alert, torrent_deleted_alert, torrent_delete_failed_alert: info_hash member is no longer a sha-1 hash, but (deprecated) implicitly convertible to one
• undeprecate error_file_metadata for torrent errors related to its metadata
• remove support for adding a torrent under a UUID (used for previous RSS support)
• remove deprecated feature to add torrents by file:// URL
• remove deprecated feature to download .torrent file from URL
• requires boost >= 1.66 to build
• update networking API to networking TS compatible boost.asio
• overhauled disk I/O subsystem to use memory mapped files (where available)
• libtorrent now requires C++14 to build
• added support for GnuTLS for HTTPS and torrents over SSL
