Migration Guide

The following guide assumes a valid v0.7.x config.json file. All changes listed below will need to be implemented in order to migrate to Airnode v0.8. This document is written in a way that will preserve existing behaviour with earlier Airnode versions, but some of the new fields have additional options that can be found in the v0.8 Airnode documentation

Summary

1. chains[n].authorizers is now an object rather than an array of strings

2. chains[n].authorizations added as a new object allowing the Airnode operator to authorize specific endpoints for specific requester contracts without having to make onchain transactions. i.e. providing an offchain way to authorize specific requesters.
