4.2.1 download missing Apache2 experimental folder

Referring to... PHP 4.2.1 zip package [5,217Kb] - 14 May 2002 (CGI binary plus server API versions for Apache, Apache2 (experimental), ISAPI, NSAPI, Servlet and Pi3Web. MySQL support built-in, many extensions included, packaged as zip) The "Apache2 (experimental)" piece apparently didn't make it into this zip file. Is that intentional? If so, I presume the current 4.2.0 release is still the most current. Is there a timeframe for a production grade API version of PHP? Thanks in advance.
