PHP 5.1 released today

[Joel]

PHP 5.1 was released today:
http://www.php.net/

However, I suspect it'll take a while for end-users to start making web
apps specifically for 5.1; after all, the majority of web hosts don't
even offer PHP 5 in their environment yet. But as support for 5.1
increases, I suspect more and more end-uses will generate code for 5.1
using POG.
