Dear documentation bug triager. This bug was created here because we did not know how to map the project name "openstack/heat-translator" to a launchpad project name. This indicates that the notify_impact config needs tweaks. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Added checking for invalid or malformed command line parameters

    The parse_parameters function needed additional logic to recognize and
    reject bad parameters. Primarily, this fix assures that each
    parameter is a valid assignment of the form 'a=b'.
