What's new in Joomla 3.8?
Joomla 3.8 stable version is around the corner, now you may download the Joomla! 3.8 Beta release for testing that's why DO NOT use the beta version on your live production website since it's still not ready and needs the final fixes and improvements before the official Joomla 3.8 stable release.
Moreover, note that the beta release cannot be upgraded which means that you there will not be an upgrade path from the beta to next higher ones. All community members who find bugs in Joomla 3.8 beta may report issues in the Joomla! CMS Issue Tracker.
