• v2.0-RC3 Changes

  August 27, 2020

  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.
