DotA 6.81d map is publicly released in the early August. This map has been released after a very long wait. This release closely focuses on balancing some key heroes which were carrying extra edge in the previous map. Interestingly there hasn't been any new hero or item included in the new map instead there are numerous heroes, cosmetics, items and gameplay balance changes have been made.
Seeing the past record its clear that fans might well have to see one more map in the few days. The further progress in the current series is under progress and fans will be able to see the new version in the short period of time. So stay patient for the next update.
