qBittorrent v4.3.0 was released.
This is a major version release due to the high number of accumulated changes and due to the long time since the last release.
Some notes:

  • Theming support has been enhanced but previous theme bundles will not work properly with this release. Please contact the theme provider for a fix. The new format is described here.
  • If you want faster tracker announce rate or are having a slower client exit(compared to 4.2.x) then you may try increasing the Max concurrent HTTP announce limit from advanced settings.
  • The latest version of libtorrent used contains many important fixes compared to the last one, including memory leaks and speed issues due to wrong caching logic on Windows.
  • Qt 5.15.1 is used which offers far better HiDPI support. However, the torrent context menu will close after each tag selection.
  • Brave users can download experimental builds from "Actions CI" on github.
