Yes - there is. You have to keep upgrading and the best idea is not to change the core files at all. That way you don't have to worry about losing your modifications every time there is an upgrade. You have to upgrade because Wordpress fix security holes - hackers are constantly trying to find ways to get into low security blogs so they can place their links back to their sites.
If you want to modify code and not be in danger of overwriting it, use the Thesis theme (or something similar) - it allows you to make major changes to your blog's functionality without changing core files.
