I have all sorts of messages littering my blog dashboard this morning telling me to upgrade to WordPress 2.3.1; I suppose that I’d better set to work with upgrading then. However, this is never something that I do without first testing on my offline blogs. And then, there’s the need to save some tweaks to WordPress source code ahead of time. I know that I could create my own plugins but that involves finding the correct hooks and it’s a subject for another time, anyway.
