Prior to this update, the output of the "nmap -h" (or "nmap --help") command did not describe all the available nmap options that begin with the "-s" or "-P" prefix. As a result, a user could have been unable to research what options can be used to perform specific tasks with nmap. With this update, the bug has been fixed so that the output of "nmap -h" now describes all the aforementioned nmap options that were previously missing from the output.
