I am running WordPress 2.3 on my website. My webhost is telling me that I need to update it to 2.6.1. They are saying that there are security issues in this version of WordPress and that I need to keep it up to date. They even mention that my blog may be disabled if it is not updated.
Is it absolutely mandatory to update to version 2.6.1? I'm afraid that if I update that it will break my blog.
