PHP 4.0.2 has been released.  This is a maintenance version, with no big 
 revolutions.  It mostly features many bug fixes, some new functionality, 
 and increased performance under certain circumstances.  Users that are 
 happy with PHP 4.0.1pl2 that aren't experiencing any of the problems that 
 were fixed, and don't need the new functionality, don't necessarily have to 
 upgrade - even though 4.0.2 is a recommended upgrade.
 
 As for PHP 3.0 users, well, time to sync in :)  I'd like to take this 
 opportunity to strongly urge people to upgrade to PHP 4.0.  The number of 
 reasons to do this is too long to be listed here, so I'll only say that PHP 
 4.0 is superior to PHP 3.0 in *every* aspect, be it performance, stability 
 or features.  The only reasonable reason to stay with PHP 3.0, temporarily, 
 is if your applications require porting to PHP 4.0 (and then too, my 
 suggestion is to try and make the necessary fixes when you get the 
 time).  Otherwise, staying with PHP 3.0 makes no sense
 
 The full list of changes is enclosed.
