In the Projects Portal you can force updates to specific drivers by clicking the "Updates Available" tab.
This will bring up a menu of all of the updates available in your projects. From here you may select each driver to be updated automatically in all of the projects in your Projects Portal.
Alternatively you may go into each project to update the drivers one by one as needed by clicking on the update button under the Action column.

Please be aware that you may need to refresh the Projects Portal before the update will be displayed on the site.
