The Testnet Crescendo Upgrade
We're excited to announce the finalized date for the next Testnet Crescendo Network Upgrade! Please note that testnet will be down for roughly 6 hours during this upgrade, and all smart contracts must be staged before the upgrade for a seamless migration!

Flow Testnet Maintenance
Flow Testnet will be upgrading on Wednesday, 14th August 2024, at 8am PT.
Flow Testnet will be unavailable between 8:00am PT to 2:00pm PT on that day.

Please plan accordingly to the date and time of this Network Upgrade. For more details on the Crescendo Network Upgrade, including how to make sure you're ready in time, you can visit here ⤵️
The Crescendo Network Upgrade is coming to Testnet!

With this upgrade, Cadence comes to a point of maturity, and will be backward compatible in future upgrades. But any Smart Contracts must be updated to Cadence 1.0 before the upgrade goes live.


Thank you,

The Flow Foundation 🌊
