qBittorrent 4.2.0 release notes:

There were no significant user facing changes since the previous RC release. ATTENTION: This release uses the libtorrent 1.2.x series. It saves fastresumes a bit differently than the 1.1.x series, which are used so far in the previous versions. If you run it and then downgrade to a previous qBittorrent version then your torrents will probably start rechecking.
