1.2 is a major upgrade from the 1.1.x series. It is not ABI compatible with 1.1.x.

Most prominent changes are:

• requires boost >= 1.58 to build
• require C++11 to build
• improved support for listening on multiple sockets and interfaces
• announce_entry no longer represents a single tracker IP, but has a list of endpoints announced to. This is to support multi-homed clients.

• alert types are no longer copyable and ownership is never transferred to clients
• deprecated alert::progress_notification alert category, split into finer grained categories
• deprecate identify_client() and fingerprint type
• deprecated public to_hex() and from_hex() functions
• remove deprecate session_settings API (use settings_pack instead)
• transitioned exception types to system_error
• move files one-by-one when moving storage for a torrent
• removed RSS support
• removed feature to resolve country for peers

1.1.12 release

libtorrent-1.2-RC2

This is a release candidate of libtorrent 1.2.0, not a final release.
This version is ABI incompatible with the 1.1.x releases.
With libtorrent 1.2.0, C++11 is required to build and in some cases the API has been altered as well. Mostly to use standard C++ types instead of boost types, but also to use more modern vocabulary types like string_view and span.

The main changes affecting the API are documented here.

The main differences since RC1 are:

• span type now use std::ptrdiff_t for size and indices, aligned with gsl::span
• the old (slow) bdecode() function has been deprecated

The updates since the latest stable release are:

• support &ipv4= tracker argument for private torrents
• renamed debug_notification to connect_notification
• when updating listen sockets, only post alerts for new ones
• deprecate anonymous_mode_alert
