Odaily Planet Daily News According to official news, Flow released an update on the testnet migration: In preparation for the upcoming Crescendo testnet upgrade, we found that a core smart contract FiatToken has not been upgraded for Cadence 1.0 migration. FiatToken is a key dependency that affects hundreds of contracts. In order to avoid interruptions to dependent smart contracts and improve the developer experience of builders on Flow, the testnet upgrade has been temporarily postponed while we work with contract owners to upgrade. Once there is a clear roadmap and timetable, the community will be informed in a timely manner.
