Transmission 4.0.4

This is a bugfix-only release. Everyone’s feedback on 4.0.x has been very helpful — thanks for all the suggestions, bug reports, and pull requests!

What’s New in 4.0.4

All Platforms

• Fixed bug in sending torrent metadata to peers. (#5460)

GTK Client

• Fixed missing ‘Remove torrent’ tooltip. (#5777)

Web Client

• Don’t show null as a tier name in the inspector’s tier list. (#5462)
• Fixed truncated play / pause icons. (#5771)
• Fixed overflow when rendering peer lists and made speed indicators honor prefers-color-scheme media queries. (#5814)
• Made the main menu accessible even on smaller displays. (#5827)

transmission-cli

• Fixed «no such file or directory» warning when adding a magnet link. (#5426)

Transmission 4.0.0

Highlights

This is a major release, both in numbering and in effort! It’s been in active development for over a year and has a huge list of changes — over a thousand commits — since Transmission 3.00. Some of the highlights include:

• Resource Efficiency — Use less memory and fewer CPU cycles
• Better Community — Pull requests welcomed and used
• Code Modernization — Migrated from C90 to modern C++
• New Features — What would a major release be without them?

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!
• Transmission 4.0.0 includes over 350 new community commits (see the Thank You section below and in the previous 4.0.0 betas) since 3.00 and welcomes new contributors.
• Documentation has been moved into the transmission/transmission so that contributors can submit PRs to improve it.

Code Modernization

• The entire codebase has been migrated from C to C++. In the process, we’ve removed thousands of lines of custom code and used standard C++ tools instead. The core’s code has shrunk by 18%. The core codebase has been extensively refactored to be more testable and maintainable.
• 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.

New Features

• 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.
• When creating new torrents, users can now specify the piece size. (#3768, #3145, #2805)
• IPv6 blocklists are now supported. (#3835)
• Beginning with 4.0.0-beta.1, Transmission releases now use semver versioning.
• Dozens of other new features — too many to list here! We’ve been working on this for a year!

Welcome to the first beta release of Transmission 4.0.0! It’s been in active development for over a year and has a huge list of changes — over 1,000 commits — since Transmission 3.00. Some of the highlights include:

• Resource Efficiency — Use less memory, fewer CPU cycles
• Better Community — Pull requests welcomed and used
• Code Modernization — Rewritten in C++
• New Features — What would a major release be without them?

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!
• Transmission 4.0.0-beta.1 includes over 300 new community commits (see the Thank You section below for a list) and is welcoming new contributors.
• Documentation has been moved into the transmission/transmission so that contributors can submit PRs to improve it

Code Modernization

• The entire codebase has been migrated from C to C++. In the process, we’ve removed thousands of lines of custom code and used standard C++ tools instead. The core’s code has shrunk by 18%. The core codebase has extensively refactored to be more testable and maintainable.
• 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.

New Features

• 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.
• When creating new torrents, users can now specify the piece size. (#3768, #3145, #2805)
• IPv6 blocklists are now supported. (#3835)
• Beginning with 4.0.0-beta.1, Transmission releases now use semver versioning.
• Dozens of other new features — too many to list here! We’ve been working on this for a year!
