The new release implements all major functions of the Service Availability Forum (SA Forum) Application Interface Specifications (AIS).

The enhanced middleware platform focuses on improved manageability, enhanced availability modelling, the ability to support root and non-root environments for flexible system design and increased testability for both OpenSAF developers and users.

Release 4.2 enables multiple appliers to simplify distribution of configuration changes throughout distributed parts of an application and offers enhancements for administrative operations that enable additional data to be carried, providing more information when an error occurs, or when a configuration change is rejected.

CCB Augmentation can be used to abstract and mediate between a high level system model seen by an operator and the detailed model of an application.

Enhancements to the Availability Management Framework (AMF) to provide increased functionality and flexibility include improved support for modelling of application dependencies and integration with the new IMM enhancements.

The enhancements also include support for the AMF B.04 API, OpenSAF processes executed as non-root, improving system security and Python language bindings for the SA Forum AIS services to enable development of test environments for OpenSAF developers and users.
