Changelog
Items listed in bold are considered potentially breaking changes from the previous released version. Potentially breaking changes include:
-
Changes to the structure of returned objects
- Addition/removal of properties or links
- Changes to the structure of composed types (e.g. collections)
- Status code changes
- Changes to default parameter values
We make a special effort not to remove properties or links, change the structure of composed types, change the class of status codes (e.g. 200 class to 400 class), or change default parameter values.
Clients should be prepared to handle changes to status codes within the same class, especially the 400 and 500 classes, and to handle the addition of properties and links to response objects.
