On the Laravel News site they've posted information about a series of videos on the Laracasts site covering what's new in Laravel 5.6.
Laravel 5.6 has been for a few weeks now and it includes a few nice new features like Broadcast Channel Classes, Collision Reporting, Improved Logging, and more.
In order to get you up to speed on all these new features, Laracasts has started a new free series, “What’s new in Laravel 5.6” that will go through each major feature of this release.
The series includes videos covering how they upgraded the Laracasts' codebase to 5.6, collision reporting, logging improvements and dynamic rate limiting. More videos will be added to the series as it goes along. You can check out the current listing of videos on the Laracasts site.
