Experimental settings

An administrator can enable certain experimental features in Settings > Site administration > Development > Experimental > Experimental settings.

An experimental feature is defined as a feature which require additional testing and bug-fixing.

• Safe exam browser
• Group members only - adding the 'Available for group members only' checkbox to the activity settings page
• CSS optimiser (new in Moodle 2.3)
• Drag and drop upload of text/links (see MDL-22504 for further details)
• New backup format (supports large backups). May become default in a future Moodle version. See Backup and restore FAQ#Using the new backup format (experimental).

Note for sites upgrading from earlier versions of Moodle:

The experimental setting 'Group members only' has been removed in Moodle 2.8. The conditional availability setting 'Restrict access' now provides this functionality. Any group members only instances are automatically converted to restricted access instances as part of the site upgrade process.
