Hi. I love WordPress. But what happenend with the 3.1.3 update pushes me to write. The automatic update get the blog to 3.1.3 and replaces the TwentyTen theme (as well).
This is fine if people haven't touched the original theme. But chances are that people had customised it (as was my case). Of course, I should have renamed it, but still. I think that updating the blog-system should not impose a theme change. These are two distinct elements, at least in my view.
Sorry for the rant. Have a nice day.
