Is the CollabNet TeamForge SOAP API backward-compatible?

The CollabNet TeamForge Enterprise Edition 5.x and CollabNet TeamForge Enterprise 6.x APIs (including Service Pack updates) are fully compatible with CollabNet TeamForge.

Applications developed using these earlier APIs will continue to function after you upgrade to CollabNet TeamForge. A release of CollabNet TeamForge may be accompanied by updates to the API. These changes are always backward compatible with earlier versions of the API. However, the calls from the different API versions are not interchangeable.

• For updates and patch releases, existing methods are incremented, not overwritten. For example, if an update is made to the createDocument method, it is reflected in a new method createDocument1. You do not have to update your existing applications to reflect a new API with any Service Pack or Hot Fix release.
• For a major CollabNet TeamForge release, such as this 17.4 release, updates are merged into a new API version. At this point, if you want to use the new API calls, you must update your existing applications.
