It would be beneficial to also run the master branch version of Gramps so as to test bugs that are in the master branch only.
* At the moment only projects Gramps 3.4
, Gramps 4.0, Gramps 4.1, Gramps 4.2 and master are supported, so any bugs not closed or resolved in older versions must be resolved one way or the other:
** resolved in the meantime
** does not apply anymore
