How updates are applied to this blog

A simple question that I have answered today. This blog needs updated every so often to ensure the best WordPress compatibility. To do this, I need to temporarily close the blog down to maintenance mode. This means that the transition will be as seamless as possible whilst as effective as possible. I will not post before doing this, but I will probably skip most minor updates, only updating on major builds (or perhaps every few builds) as I want to keep disruption as minimal as possible.
