According to IceFrog, the long-awaited patch will be out in one or two weeks. This patch will focus on the balance of the game for the upcoming tournaments. There is still not any new regarding the new hero he introduced us a few months ago.


Here is the full post:
The update is nearing completion. It took a little longer than anticipated, but it should be ready soon. The primary focus of this patch is to provide overall balance and gameplay improvements, while the follow-up content for 6.70 is still being developed. Of course you can still expect the traditional .x9 quest to be included!

I plan to release this within a week or two to provide some time before the start of some big tournaments in the following months.
