WordPress.com is no longer part of the WordPress core, but an administrative interface that connects to it just like other third-party apps. The separated version of new WordPress interface uses REST API for fetching your posts, publishing new ones and uploading photos among its various other interactive functionalities.
Elaborating this further, the WordPress interface, once it completely loaded from the server, becomes a single page application. So there will be fewer loading screens and faster response. More good news, it will also run flawlessly on your smartphones and tablets as well just like another responsive WordPress website themes. Not to mention, the backend is still accessible, with additional options for hosted and self-hosted blogs.
Finally, we arrive at what everybody is talking about… WordPress.com has gone open source, putting everything on GitHub for developers to access and improve. You can view the code, fork it and reuse, but you must comply with the General Public License (GNU) version 2. Do you feel excited? Well, keep it under control because there is more!
WordPress also offers you a new downloadable Mac app to access the platform, which essentially works like the Slack desktop app. It boosts web technologies and combines it with desktop’s convenience so that you get a highly organized WordPress interface right on your PC, with additional goodies like desktop notifications. If you are on Windows or Linux, don’t lose your heart because WordPress team is working on their apps too.
