Comment (by RJVB):

 You don't need to worry about the 5 "beta" status, the application works
 as well with Qt5 as it did with Qt4. Probably better (faster) and more
 reliably on such a recent OS where Qt4 is likely to start showing its age
 and lack of updates.
 In fact, the "5 beta" version is just the stable 4.x release with the
 minimum changes required to make it build against Qt5. I think Martin is a
 bit like me in that he probably forgets about details such as version
 numbers when software just works.

 I did make a few more tweaks to my own version but nothing that I felt
 needed "upstreaming".
