I looked through meta-arago and meta-qt5 about a month ago for compatability.

I checked again today:

meta-qt5/master	= 5.3.0
meta-qt5/daisy	= 5.2.1
meta-qt5/dora	= 5.1.1

meta-arago/master = 5.2.0
meta-arago/dora   = 5.2.0 (used to be 5.1.1)
There is no meta-arago/daisy branch.

The only revision I could find which was available in both was 5.1.1.
and that is why I used it.

It would make sense if the qt5 related recipes in meta-arago matched those in meta-qt5.

Now meta-arago is using 5.2.0 which is not present in any branch of meta-qt5 (did not check old branches, only dora and daisy).

I dont understand why the meta-arago:dora recipes for qt5 has been updated from 5.1.1 to 5.2.0, 
thus making it incompatible with meta-qt5:dora. Isn't this a mistake.
