yeh I emailed hm last night, haven't gotten to check that email today yet though; I will likely pay for the upgrade to the latest build then hack in some php5/reg globals off support (honestly, it really ins't that hard).
One thing to keep in mind is that, from what i hear, safemode and registerglobals won't be an option in PHP6, so cleaning them up in php5 should be a priority for programmers...
