Flow: Temporarily postponed the Crescendo testnet upgrade because it was found that the core smart contract was not ready for migration

Odaily News According to official news, Flow released an update on the testnet migration: While preparing for the upcoming Crescendo testnet upgrade, we discovered 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 disruptions for dependent smart contracts and improve the developer experience for 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.
