Blockdaemon will update Cardano Ogmios nodes to v7.0.0 on 07/14/2026 at 10:00 UTC. We are updating our nodes due to a release from the Cardano foundation. This update applies to all Blockdaemon Cardano Ogmios nodes, there will be planned downtime of up to 30 minutes per node.
Please be aware that the Ogmios release contains the following breaking change: - on ProtocolParameters and ProposedProtocolParameters, the field maxReferenceScriptsSize has been renamed to maxReferenceScriptsSizePerTransaction to disambiguate it from maxReferenceScriptsSizePerBlock. - transaction object now omits the validityInterval and outputs fields when they're empty. - Byron bootstrap witness encoding has changed from a single 64-bytes key payload to a combo key + chain-code.
Removed: transaction submission and evaluation no longer include shelley, allegra and mary parsing hints on errors. Only alonzo onwards is included.
We have tested the release and do not anticipate any unexpected downtime other than mentioned above as a result of the update. If you have any questions or concerns please reach out to your Customer Success Manager.
