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.
