This is to avoid any confusion + where a response was generated elsewhere in the pipeline and not in + direct relation to the original exception. If anyone upstream wants to + catch and render responses for exceptions they should set + ``request.exception`` and ``request.exc_info`` themselves to indicate + the exception that was squashed when generating the response. + + This is a very minor incompatibility. Most tweens right now would give + priority to the raised exception and ignore ``request.exception``. This + change just improves and clarifies that bookkeeping by trying to be + more clear about the relationship between the response and its squashed + exception.
