Hello,
Please note that the protocol_version field from the NodeVersionInfo endpoint of the Access API will be removed next week.
A new field protocol_state_version has been added instead.
See changes to API definition here and to the node software here
Original deprecation notice: 18th Feb Height Coordinated Upgrade Release Notes under ⚠️ Deprecation.
This is part of the larger change to protocol versioning as discussed earlier.
Thank you,
Flow Team
