On certain system configurations we offer a 1-click update which will download the latest release.
This feature is only available when php-zip is enabled and the folder is writable by the apache user.
When an update is available, the main administrator will see an “Update” under the “Help” section. You can check for updates by going to Help > Check for Updates.
