One more update soon?
On the official blog, the main Game Deva of Dota 2 IceFrog announced the approximate release of 6.85 patch on the next week. The main amendments will influence the game balance, which will impact the preparation to the Fall's Major qualifiers.
It's yet unclear what the minor changes of balance imply. It can be both a small fix of a hero and the total change of a hero, which will result in its "elimination" from the pick even in public games (as it happened with Terrorblade).
Big changes can be expected in 6.86, to be released after the first major. Most likely it's the time of introduction of new hero Arc Warden.
