[Qgis-developer] QGIS and GRASS Plugin: How?

[m roy]

Hi,

I'd like very much to use QGIS with the awesome new GRASS plugin,
but lately it seems to be harder and harder (at least for me) to achieve 
this goal.
What i find really very confusing is what release (on windows) or PPA 
(personal package archive
on ubuntu) we are supposed to use to have QGIS working with GRASS.
Now i do not have a fully working QGIS+GRASS system in windows (using 
OSGEO4W)
nor in Ubuntu 14.04 because GRASS GIS in ubuntugis-unstable is no more
compatible with QGIS or vice versa...

I think that QGIS and GRASS GIS enormously benefit each other
and really hope someone could give advise on what 
package/osegeo/ppa/stable/unstable/installer
to use to simply have QGIS and GRASS run together :-)

thanks, Roy.
