Porting plugins to MuseScore 4.4

How to check for museScore version in 4.4?
In the updated CourtesyAccidentals plugins in
https://github.com/musescore/MuseScore/commits/7fe32bacbc9287b716d40462…
i see that this check has been disabled.

   *if (mscoreMajorVersion == 3 && mscoreMinorVersion == 0
            && mscoreUpdateVersion < 5) {
        versionError.open();
    }*

Is this because this does not work anymore?
