That's why I wanted to ask about it. I can imagine there is a lot of inertia in a shared environment against a semi-major update like this, and not a lot of incentive to make it available, since a lot of the stuff that might break now will probably still be there months from now, and the same breakage screams... . You don't have any plans to make 5.3 available as an alternative/dual install so that individual accounts can enable it via .htaccess configuration? I could get by without it for awhile if I have to, but since it is generally available to me in OSX at work and at home, it would be a shame to have to avoid it if I want to throw something up on my site.
Will do - I won't have time to actually migrate to whatever new host I choose until next weekend at the earliest, so I wasn't in a big rush for the answers.
Thanks,
