From this release, an error handler service provided by the CloudStreams provider is invoked to handle the error events. The error handler service does the callback on a custom callback service provided by the user to take further action based on the error handler service output. Thus, user can ensure that the listener is fault tolerant by enabling the error handler and listener runtime errors are reported and appropriate action taken.

From this release, a Connector Developer can define lookups for a field available in the header, parameter, or input signature. This capability allows the CloudStreams Development UI to show a list of options from the back end to the end user for header, parameter, or signature field for which lookup is defined.
