Just a quick note from a pointer on PHP Magazine - according to a posting from the php-dev mailing list by Andi Gutmans, RC1 might be just around the corner.

I have posted RC2 of RC1 (http://www.php.net/~andi). I am hopefully rolling RC1 tomorrow unless something unexpected comes up. Please try out this package because it was rolled on the new snaps machine (thanks Derick) and I want to be sure that it's OK.

So, keep an eye on the main PHP.net site (or your favorite mirror) for this upcoming release...
