Announcement on Cancellation of Upgrade GreatVoyage-4.5.0

Dear developers,

We are receiving feedback from some developers that after upgrading to GreatVoyage-v4.5.0 (Nietzsche), the node's smart contract query API is unstable, there is a small chance that an abnormal state will be returned. The relevant team is already investigating in depth.

This problem does not bring any safety issue and risks to any on-chain assets. However, in order to ensure the stability of all business activities, it is recommended to cancel the upgrade. If you have upgraded to version 4.5.0, please observe if this abnormal state return occurs. If so, you may roll back to version 4.4.6. Detail follow-up upgrade arrangement will come shortly.
