Running the upgrade script is required.

Before performing any upgrade please remember to backup your forum’s files and database and store them safely. If you have edited core files, including language files, please make sure you make a changelog for these changes so you can make them again (if necessary) once the upgrade is complete.

Follow the Upgrade Documentation for more detailed instructions.

Note: this version removes the discontinued “Yahoo” profile field, which may have been customized for other purposes.
