Could the changelog for 2.9b5 be any more specific than “some of bugs are fixed;”?! 
It’s the same thing with the other beta releases, some or a lot of bugs are fixed.
I know, but for bug reporting it would be handy to know if a certain feature should be there or should work (and I can report a bug, if it doesn’t), or if I don’t need to bother reporting it as it’s not supposed to work anyway…
