I’ve been following closely the WordPress 3.2 release in the past week and have noticed a small detail that some of us may not have seen. That is version 3.2 requires a minimum of:

PHP 5.2.4 and MySQL 5.0.15

For most people who have a host that’s on top of things, this will not be a problem. Still, it never hurts to check!

However, I wanted to point this out because I know some clients have sites that still run on MySQL 4 and even PHP 4 until very recently. So before you go and happily hit the update button, make sure you check your servers first. WordPress.org recommends the health check plugin.

A note on the health check plugin. A lot of people get confused with the version numbers. For example, you may see: Your server is running PHP 5.2.17 and tells you, you are good to go.

Due to the way we are all taught to look at numbers, you may be thinking 5.2.17 is less than 5.2.4 (the minimum). Actually it is not. What you should be focusing is the last number – 17. 17 is a later version (or larger number), after 4. In that sense, you’re good to go.

Thought I’d mention this because there were a lot of questions about this and for a moment there, I had to stop and think about it as well.
