For a full list of changes in PHP 4.2.1, see the ChangeLog.


PHP 4.2.1 also has improved (but still experimental) support for Apache version 2. We do not recommend that you use this in a production environment, but feel free to test it and report bugs to the bug system.

External variables

We would also like to attend you on a big change in PHP 4.2.0 concerning variable handling.

The preferred method of accessing these external variables is by using the new Superglobal arrays, introduced in PHP 4.1.0. More information about this change:
