New in Transmission 4.0.0 (Feb 9, 2023)

  • Resource Efficiency:
  • The code has been extensively profiled and improved to fix inefficient code and memory use. For example, a stress test of starting transmission-daemon with 25,000 torrents is almost entirely IO-bound, using 50% fewer CPU cycles and 70% fewer memory allocations than Transmission 3.00.
  • The remote control GUIs (transmission-qt and transmission-web) now use the RPC API "table" mode, resulting in smaller payloads / less bandwidth use.
  • RPC payloads are now compressed using libdeflate, a "heavily optimized [library that is] significantly faster than the zlib library."
  • Community:
  • The project is much more responsive to bug reports and code submissions than it has been in the past.
  • There is a new group of volunteer contributors who are working on Transmission!

  • The GTK client has been ported to gtkmm.
  • The Web client has been rewritten in modern JavaScript and no longer uses jQuery. The entire gzipped bundle is now 68K.
  • The unit tests have been expanded and ported to Google Test. Clang sanitizer builds are run during CI.
  • The core library is now fuzz tested.
  • Transmission now uses Sonarcloud, Coverity, LGTM, and clang-tidy static analysis on new code. Several hundred code warnings have been fixed compared to Transmission 3.00.

  • Support for using BitTorrent v2 torrents and hybrid torrents. (Support for creating v2 and hybrid torrents is slated for an upcoming release.)
  • Users can now set "default" trackers that can be used to announce all public torrents.
  • Newly-added seeds can start immediately and verify pieces on demand, instead of needing a full verify before seeding can begin. (#2626)
  • Added an option to omit potentially-identifying information (e.g. User-Agent and date created) when creating new torrents. (#3452)
  • The Web client has been rewritten and now supports mobile use.
