The developers of the BitTorrent client qBittorent recently released an update to version 4.3.0 with several changes and fixes.
If you are already using this client to download torrents, you have probably received an update notification when starting qBittorent, if not go to the software menu on Help> Check for updates to run the update manually.
qBittorent 4.3.0 is therefore the first version since April 2020 and brings the customer several improvements and changes whether in terms of the interface and its ergonomics or its functionalities and performance.
This version uses the latest version of the libtorrent Library, the open source implementation of the BitTorrent peer-to-peer (P2P) file sharing communication protocol, which fixes poor memory management and improves at the same time the download speed on Windows. qBittorent 4.3.0 also uses the new Qt5 libraries (5.15.0), which offers better HiDPI support.
There has also been an improvement in theme support, but previous theme sets will not work properly with this release.
