Description

The pcs builds mentioned in the description were not released. We took following actions to prevent this kind of issues: - focus on forward and backward compatibility when designing new data structures and API calls - check if an item is present in a data structure sent from other pcsd instances instead of simply reading it and rely on its presence - check for cases when a pcsd instance does not support requested operation (e.g. returns HTTP 404 code) and handle them appropriately - keep a backward compatibility layer when changing functionalities - implement functions to discover capabilities of a pcsd instance - check for cases when it is not possible to fulfill a request due to incompatibility, handle them gracefully and display an error message Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
