Share Article

A new UX, a new technology stack, the same ease of use and open source approach.

PortlandLabs released version 5.7 of concrete5, a major update to the popular content management system. Both the interface and technical architecture have been revisited from the bottom up in every way.

“We’ve had in-context editing working in our open source framework for years, but with this version’s interface update we’ve really added a level of polish that makes it feel like you’re just using a word processor to edit your website.” explains PortlandLabs CEO Franz Maruna. “Anyone can quickly pick up editing a site with concrete5, but we’re also a mature open source platform with versions, permissions, workflows, and an extendable override structure under the hood. Concrete5 has everything an organization needs to be successful with their web presence.”

Andrew Embler, PortlandLabs CTO elaborates, “With two years of development and a no-limits approach to what we tackled, it is really exciting to launch 5.7 today. Editing functionality is smoother and more refined, theme developers will love our integration with grid systems and LESS, and we’ve created more flexibility in the way pages are created. We’ve also fully modernized and rewritten our development platform, taking advantage of modern PHP features like Composer and libraries like Laravel, Symfony2 components, Doctrine and much, much more. It’s awesome to be working with the latest and greatest out there.”

The team is particularly excited about the inclusion of Redactor as a text editor. This extremely clean javascript HTML editor is deeply integrated so editors are writing text in-line on the page but can still use concrete5’s file and link management. “The team at Imperavi generously has allowed us to include a version of Redactor under the LGPL - it is a great tool that any application developer should look seriously at for their HTML editor needs.”

This is a production ready release that add-on and theme developers should update their extensions for. A follow up release with marketplace integration and performance optimization is scheduled for September 30th. Learn more about the latest version of concrete5 at
