This change applies to API checks that assert JSON bodies in response arrays, enabling the use of JSON path expressions to check individual elements within the array. The new regime will apply to a tiny percentage of users, mainly those who have assertions with JSON paths that target specific elements in the array. This change may break certain assertions that previously checked the entire array as a whole, but many existing JSON path queries will remain unaffected. Users are advised to review their API checks and remove any assertions that target individual elements in the array, or set reminders to add similar ones after November 2nd. The change is expected to be released on November 3rd, and users can expect alerts if their checks fail as a result of this update.
