Blizzard has announced that the Weekly Mythic+ testing window will open shortly with all dungeons and updated keystone affixes being testable. However, from datamining, it doesn't look like the updated affixes are actually in as things like Bolster and Enrage still having their current effects.
Freehold was updated with some tuning changes though.
