Service update: This service will be updated when new operational needs are identified. Please get in touch with the Service Provider Point of Contact for any evolution request regarding this Service. Backwards compatibility is guaranteed between minor versions but not for major. Given a version number MAJOR.MINOR.PATCH, ACG will increment: the MAJOR version number when incompatible API changes occur, the MINOR version number when functionality evolve in a backwards compatible manner, the PATCH version number when backwards compatible bug fixes occur.
