As the site migration went so well, and as everything is looking stable ... ... ... our Site Geek (praise his nurdly appendages) has decided that it's time to upgrade the site software. The version of PHP being used is getting on a bit now, admittedly, so he's probably correct. He's thinking of doing it at some point in the next few days, but don't worry - we'll do our best to warn you when it's going to happen.
The last time John tried anything like this it all went pear-shaped, as he'd never done it before. And as it went pear-shaped and he had to reinstate the old software, he still hasn't done it before. Don't let this worry you in any way
It will all go swimmingly and we'll hardly notice anything. It will. Honest. No, seriously - I have utter faith in John's abilities.
