According to Foresight News, the Stacks Foundation tweeted that its core developers said the Nakamoto testnet hard fork planned for this week has been successfully activated. During the testnet upgrade, the core developers found some bugs related to node communication, and a reset may be done over the weekend to eliminate some of the problems. Currently, most of the testnet is running normally, and the official plan is to release an update on the details of the hard fork before October 4.
