Questions about Éclair versions

How do I update Éclair to the latest version?

Download a backup, replace the app and assets folders, along with index.php and .htaccess, with the ones from the new version, then clear the cache in Settings › Advanced. Your content (data) and images (media) are never touched. It’s all explained in the documentation.

How can I tell which version of Éclair is installed?

Open the index.php file at the root of your site: the line define('ECLAIR_VERSION', '1.2.0'); shows the installed version. Then compare it with this changelog.

Can an update break my site?

An update doesn’t modify your content, settings or images. Only a custom theme in app/theme needs to be put back afterward, so keep a copy of it.

Where can I report a bug or suggest a feature?

On Éclair’s GitHub repository, or through the contact page.
