I took the plunge and upgraded to WordPress 2.7. So far, so good. Nothing seems to be particularly broken. The administrative interface is very different from the last version but I’m getting used to it. It feels like some information takes more clicking to get to. I also don’t like the new color scheme. It’s very gray.
Soon the theme I use, Tarski, should be putting out a new version that will take full advantage of WordPress’ new features. Once December hits and I have a few free days, I will be coding up a few templates and plugins for the site to make it a tad bit prettier, too.
My final concluision: 2.7 is a Good Thing. I will be much happier though when it’s out of beta.
