    Check whether the features you are currently using have seen bug fixes otherwise you can keep using the same code with the same import versions.

  • Thanks for that info. As suggested, bug fix can be checked with the Qt's official Release Note.
    Is there anything more which needs to be considered or looked upon like performance improvement in terms of CPU, Memory consumption or any other factors.
