It was only one of the proposals at this conference. However, as I understand from this article, the proposal of the main developer of Ethereum, Tim Beiko, who proposed September 19 as the tentative date for the merger, was accepted. Moreover, it is indicated that this target date did not raise objections from the main developers. So I think that this fall we will already see an updated Ethereum network. Recently, Buterin suggested that this date could be moved to October, but not later. Of course, if there are no other unforeseen difficulties.
