British terminology
In MuseScore3 we had minim, crotchet, quaver, bar and all the other British terms. In MuseScore4 we appear to have only the American terms half-note, quarter-note, measure etc. I hope it won't be too long until we get an update with names that we Brits are used to.

That should be the case already.
