We are planning an upgrade of php tomorrow night, 
(Thursday Jan 21st) starting at around 9 PM PST.  It
will take several hours to update the entire webhosting
cluster.

We have been testing the latest version (5.2.8) for
several weeks now and are satisfied that it should be a
drop-in replacement for the previous version.  Please
let us know if you run into any issues Friday!

I should also note that the upgrade is not yet planned
for dedicated servers.  Send us an email if you're on a
dedicated server and you would like us to upgrade your
server as well.

Cheers,
