Coaster CMS can be upgraded through the dashboard or via the composer update command. To update Coaster via the dashboard, login and navigate to system settings. From here click on the "Site Health" tab. If there are any updates available, an update button will appear. Simply click this button and updates will be installed.
If you'd rather update Coaster through the command line you can navigate to your sites root directory and run the "composer update" command. This will ensure that all packages are kept up to date.
