Release notes

The developer portal release notes are organized by the month and year of the release, starting with the most current. We also identify the affected APIs and the level of impact for the changes made. This is a quick cue to know if you need to make any necessary changes immediately or if you can integrate the API enhancements at your own pace.

We categorize changes as either breaking or non-breaking.

• Breaking changes require upgrading to a new version of the API framework. These changes can cause incompatibility and possibly disrupt your connection to API services. Some examples of breaking changes are a change to the type of a parameter, removing request fields, or developing an existing object with additional parameters.
• Non-breaking changes are changes that do not require you to upgrade to a new version or disrupt your connection to current API services. Some examples of a non-breaking change are to add an optional parameter field like a custom data field or removing a deprecating parameter no longer valid or in use.
