Hello Flow **Testnet Access Node** Operator,

If you are running a Flow **Testnet**  **Access Node** , please upgrade to version [v0.39.0](https://github.com/onflow/flow-go/releases/tag/v0.39.0) by end of this month (28th Feb).

Docker tag: `v0.39.0` (alternate docker images: `v0.39.0-arm`, `v0.39.0-without-netgo-without-adx`, `v0.39.0-without-adx`)

Do _ **not** _ delete the data folder.

Testnet will be upgraded to support the new mechanism of coordinated upgrades for all node types in the first week of March. Access nodes not running `v0.39.0` will stop working after that.

No change to mainnet nodes.

Thank you,  
Flow Team
