Previously, some kinds of errors would throw nice and fun cascades of exceptions. We now have a nice, clean error page for 500 and 503 (backend connectivity) errors which includes minimal debugging information for productive setups and a traceback for development setups. In any case, the full exception is logged to the log with an error ID which is printed on the error page.
