The SOAP API signature will change between minor releases, typically to add new functionality or to extend existing features.

Some of these changes might require a refresh of the client libraries generated, for instance Apache Axis 1 SOAP stubs must be regenerated if a complex type receives a new property. Such changes will be announced before the release of the new MantisBT version on the mantisbt-soap-dev mailing list. Typically there will be two weeks time to integrate the new SOAP stubs.
