Migration Guide ​

The following guide assumes a valid v0.10.x config.json file. All changes listed below will need to be implemented in order to migrate to Airnode v0.11.x. This document is written in a way that will preserve existing behavior with earlier Airnode versions.

The document also mentions changes to user facing services related to Airnode, such as airnode-deployer, airnode-admin, etc., and new features.

Summary ​

1. ois[n].oisFormat updated to "2.0.0".

2. nodeSettings.nodeVersion updated to "0.11.1".

3. ois[n].endpoints[n].preProcessingSpecifications and ois[n].endpoints[n].postProcessingSpecifications have an updated allowed Node environment value.

4. chains[n].authorizers.requesterAuthorizersWithErc721 and chains[n].authorizers.crossChainRequesterAuthorizersWithErc721 added.

5. Section nodeSettings.oevGateway was added.

Details ​

1. ois[n].oisFormat

Updated to "2.0.0"

{
- "oisFormat": "1.4.0"
+ "oisFormat": "2.0.0"
}

2. nodeSettings.nodeVersion

Updated to "0.11.1"

{
- "nodeVersion": "0.10.0"
+ "nodeVersion": "0.11.1"
}

3. ois[n].endpoints[n].preProcessingSpecifications and ois[n].endpoints[n].postProcessingSpecifications

Removes 14 from the Node 14 environment value to represent that the Node version of the pre- and post-processing environments is dictated by the Node.js version of Airnode. As of v0.11, the Node.js version of Airnode was upgraded from 14 to 18.

{
  "preProcessingSpecifications": [
    {
-     "environment": "Node 14",
+     "environment": "Node",
      "timeoutMs": 5000,
      "value": ""
    }
  ]
}

{
  "postProcessingSpecifications": [
    {
-     "environment": "Node 14",
+     "environment": "Node",
      "timeoutMs": 5000,
      "value": ""
    }
  ]
}

4. chains[n].authorizers.requesterAuthorizersWithErc721 and chains[n].authorizers.crossChainRequesterAuthorizersWithErc721

Adds two new authorizers, requesterAuthorizersWithErc721 and crossChainRequesterAuthorizersWithErc721, that enable request authorization using ERC721 tokens. These new fields are required, but their values may be empty arrays if this feature is not required. For further details, see the Authorizers page.

"chains": [
    {
      "authorizers": {
+       "requesterAuthorizersWithErc721": [],
+       "crossChainRequesterAuthorizersWithErc721": [],
        "requesterEndpointAuthorizers": [],
        "crossChainRequesterAuthorizers": []
      },
    }
  ]

5. With the new OEV gateway feature there's a new section in the config.json file for it. The new section nodeSettings.oevGateway needs to be added in order for the configuration file to be valid.

{
  "httpSignedDataGateway": {
    "enabled": false
  },
+ "oevGateway": {
+   "enabled": false
+ },
  "logFormat": "plain",
  "logLevel": "INFO",
}

Read the OEV gateway doc to learn more about this feature.
