To upgrade from any previous 3.0.x release, simply upload the files inside the attached tar file over existing files (7-zip is just one of many tools for tar files). After this is done, run http://mybaseurl/force_upgrade.php and choose to clear caches.
Alternatively, if you are running 3.0.7 or higher, you may copy the URL of the attached tar file, and feed it into the http://mybaseurl/force_upgrade.php script on your website to allow it to automatically extract the files; then use the script to clear caches.
For more details, see our upgrading tutorial.
