October CMS is a content management system built on the Laravel Framework. It's been in development since 2013 and is definitely part of a new generation of PHP of content management tools.
As a fresh initiative October contains little baggage. It builds on the popular Laravel MVC framework that heavily utilises Symfony components for crucial low level operations.
In addition it uses the Twig templating system, rather than the Laravel standard Blade. This all leads to a content management system that is familiar to many developers, especially if you've got a background with Laravel development.
October CMS offers an integrated marketplace with plugins and themes. For basic features out of the box it is also quite fully featured with features such as multilingual capabilities, multisite and media management.
