Which version of PHP should I be running on our DH VPS supporting WordPress?
Currently 5.2.17. A quick look at php.net shows that 5.4 has been released for almost a year. While I appreciate a careful approach to stability (I run a Debian file/mail/application server for a client), even Debian stable is including PHP 5.3.
If an upgrade is appropriate, where is the best place to learn about how to do that for our DH VPS?
If there is more than one answer to the 'which version' question, where is the best place to learn about the tradeoffs between my choices?
