The anticipated release of WordPress 4.4 is Tuesday, December 8. The release will include the first half of the WordPress REST API, responsive images, term meta, a new default theme called Twenty Sixteen, oEmbed for WordPress, and many small updates.

The leads for the next WordPress updates are as follows: Mike Schroder for 4.5, Dominik Schilling for 4.6, and Mullenweg for 4.7.

The WordPress REST API

Mullenweg discussed examples of projects that have done awesome things with the REST API:

  • Microsoft’s new ERP solution and Microsoft Dynamics AX use WordPress REST API for moving content within the application.
  • Nomadbase, a tool built by Human Made that allows you to check-in and update your location all over the world, uses the REST API as a back-end solution.
  • StoryCorps, an application that lets you record and upload interviews, uses the REST API to be the connecting piece between a mobile app and the website.


Matt Mullenweg’s State Of The Word AddressMullenweg spent some time discussing Calypso, the codename for WordPress’s new architecture, which is 100 percent JavaScript. It is fully responsive, more social, facilitates great multisite management and works with both WordPress.com and WordPress.org sites. While only on version 1.0, expect more to come.



Recently launched, Mullenweg called PHP 7 the most important version of PHP that has been released since the start of WordPress, as it is faster than any other PHP versions to date and offers better stability.

JavaScript Interfaces and PHP APIs are the Future of WordPress

Matt Mullenweg’s State Of The Word Address“I believe quite strongly that JavaScript and API-driven interfaces are the future of not just WordPress but the web,” Mullenweg said. The best way to build a plugin is with this combination. He stressed the importance of customization, as it’ll help to improve the new user experience.


He added that WordPress will reverse the trend of closed APIs.

Homework Assignment – Learn Javascript

Mullenweg gave the audience a homework assignment to “learn Javascript deeply,” adding, “It’s what’s going to allow WordPress to thrive for the next 13 years.”.

“I think we can use this opening up, API-driven development to actually open up more of the web,” Mullenweg said. “We have a very exciting year ahead of us making the web a more open place.”
