- update with commits added after 2022-06-10
- credits for the website redesign
- update with commits newer than 8a77f571ecf2503989f77ebaf7f9ba952bc4c9c5 (Thu Aug 4)
- the whole thing needs some copyediting. It's not as focused as it could be.

### Community
The project is more responsive to bug reports and code submissions than it has been in the past. Transmission 4.0.0-beta.1 includes over 250 new community commits (see [the Thank You section below](#Thank-You) for a list) and is welcoming new contributors.
The project is far more responsive to bug reports and code submissions than it has been in the past. It also has a new group of volunteer contributors who work on the project. Transmission 4.0.0-beta.1 includes over 250 (FIXME) new community commits (see [the Thank You section below](#Thank-You) for a list) and is welcoming new contributors.
### Resource Efficiency
libtransmission and the Qt client have been profiled and re-profiled to avoid unnecessary memory allocations and to fix inefficient code. 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 temporary 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](https://github.com/ebiggers/libdeflate), a "heavily optimized [library that is] significantly faster than the zlib library."
libtransmission now uses [fast_float](https://github.com/fastfloat/fast_float) for faster floating-point parsing of JSON.

### Code modernization
### Code Modernization
- The entire codebase has been migrated from C to C++. In the process, we were able to remove thousands of lines of custom code and use standard C++ libraries instead. libtransmission's source code size has shrunk by 15% compared to Transmission 3.00.
- The GTK client has been ported to [gtkmm](http://www.gtkmm.org/en/).
- The Web client no longer uses jQuery and uses modern JavaScript.
- The unit tests have been ported to [Google Test](https://github.com/google/googletest). Many new tests, including fuzz testing, have been added. CI has been improved to run sanitizer builds of the tests for new code.
- Transmission now uses Sonarcloud, Coverity, and clang-tidy static analysis on new code. Hundreds of code warnings have been fixed compared to Transmission 3.00.

- Transmission now uses Sonarcloud, Coverity, LGTM, and clang-tidy static analysis on new code. Hundreds of code warnings have been fixed compared to Transmission 3.00.
### New Features
- Transmission 4.0.0 now supports .torrent files that were created with the [BitTorrent v2 spec](http://bittorrent.org/beps/bep_0052.html). 4.0.0 users will be able to download and seed torrents created by both BitTorrent v1 and v2. Support for _creating_ v2 torrents is slated for the next major release of Transmission.
- Support setting "default" trackers that can be used for announcing all public torrents
- Newly-added seeds can start immediately and verify pieces as needed, instead of requiring a full verify before seeding can begin ([#2626](https://github.com/transmission/transmission/pull/2626))
- Added `transmission-create` option to omit potentially-identifying information, such as User-Agent and date created, when creating torrents. ([#3452](https://github.com/transmission/transmission/pull/3452))
