Joomla! has a registration system that allows users to configure personal options. Out of the box, there are nine user groups with various types of permissions on what users are allowed to access, edit, publish and administer.
Speedy page loads are possible with page caching, granular-level module caching, and GZIP page compression.
If your system administrator needs to troubleshoot an issue, an extended debugging mode and error reporting are invaluable. The FTP Layer allows file operations (like installing Extensions) without having to make all the folders and files writable, making your site administrator's life easier and increasing the security of your site.
Microdata library implementation
Developers will now be able to incorporate microdata more easily into their extensions and sites. From automating the Author tag in articles, to generating detailed markup for directories of information, the microdata library will significantly enhance how you can optimise SEO with Joomla.
PHP 7 Support
As of Joomla! 3.5.0, Joomla! supports the most recent release of Zend’s PHP: PHP 7, which provides a significant performance boost to your website. Joomla! users can enjoy the benefit of that performance improvement. Joomla! still provides legacy PHP support going back to PHP version 5.3.10 for web servers that have not yet upgraded.
