I've finished building all the variations of the recently released PHP 4.0.5 & put together a new page specifically for PHP, http://silk.apana.org.au/php/ which is also mirrored at apache.org. The full list of changes can be found on http://www.php.net/ though I should add that php.ini handling is now fixed in my OS/2 port (was broken in 4.0.4 as many of you noticed).
