It's Time To Do More!
PHP 7, released in November 2015, will provide a significant performance boost to your website. Many web hosts already provide this as an option in your hosting account and it is highly recommended that you enable it.
Quoting the PHP 7 release note on Zend, “ This is the most important change for PHP since the release of PHP 5 in 2004. … You can expect to see up to 2x faster performance and 50% better memory consumption than PHP 5.6, allowing you to serve more concurrent users without adding any hardware”.
Adding support for PHP 7 has caused a minor backward compatibility break but no major impact is expected from this. You can read more about this change here.

Now you can safely customise the Protostar template styling using your own user.css file. Any changes made to this file will not be overwritten on an update so you don’t have to worry about losing your changes.
You no longer need to scroll down the page to find the “readmore” or “insert image” buttons. Editor extension buttons that used to be placed below the text area can now be found in the toolbar where they belong.
The Category Manager now displays the number of published, unpublished and trashed articles in every category. This will make managing the structure of your site easier and help to find unused categories etc.
Joomla! has taken a big leap into the mobile space with a total overhaul of both its frontend design and administrator interface.
Joomla! administration has a friendly look and feel, built with the power of Bootstrap responsive framework, along with a touch of the awesome UI/UX work of the Joomla! JUX team.
{less} CSS and jQuery were added so you can write less code and use the Icomoon font icon library, that provides a wealth of retina-optimized icons.
Joomla! was the first major CMS to implement two-factor authentication. Add a single-use code received on your cell phone or a Yubikey to your existing passwords to make your site extra hack-proof.
