How can I upgrade to version 3.0 as a user? I am an end user and see there is a 3.0 version. Can I upgrade for free and what steps do I need to take to do that?
Upgrade instructions are found here, although i wouldn't recommend it as an end user. You want to backup your database in case something goes wrong, change file paths/content, etc. Even if you have the access and knowledge to run the scripts, you should have a developer do this for you.
