These are changes that were listed in the last Preview but weren't working as listed in those notes; now they are. There were not design changes between the last Preview and this build (though there is one missing as Lynn points out below).
I'll have to double-check if those notes made it into the last Lamannia, but it's essentially "Anything we listed in the Forum Preview of the ED pass as scaling with Melee or Ranged Power now works as its tooltip says it does".
