Previously, when a stack update failed the Orchestration service continued to store the old parameter values instead of the ones supplied with the failed update attempt. Whenever this occurred, the Orchestration service incorrectly showed the parameter values from the last successful update. If the parameter schema of the template changed, attempting to show the failed stack sometimes resulted in an error.
With this release, the Orchestration service now updates stored parameter values with new values during and after a failed update. As a result, when showing a stack, the parameter values will be the last ones supplied (as expected) even after a failed update.
