According to Odaily, the Stacks Foundation announced on X that the Primary Testnet has successfully undergone a hard fork and is now running the full version of Nakamoto. This marks the final 'rehearsal' before the mainnet hard fork and is proceeding as planned. Core developers expect to observe at least five consecutive days of stable behavior on the Primary Testnet before making a decision next week. During this period, various teams and contributors will continue testing through transactions and activities.
