Subject: Re: [PHP-DEV] Upgrading php
From: andi@zend.com (Andi Gutmans)

Hi Todd,

I'm hoping that in future we can provide better tools for upgrading 
in between versions. Both from an auto-conversion perspective and 
just scanning the code statically and printing out warnings on what 
code to check. Coupled with better upgrading docs I think we'd 
improve the current situation significantly.
Main problem is that currently there haven't been the people to get 
it done. We did write some upgrading docs for 5.1 (not sure if they 
made it into the RC but they can always make it to the site), but 
this whole area needs a lot more work and help.

Andi
