Following WordCampUS late last year, Steph Yiu gave a great overview to WordPress.com’s VIP users and their support teams on the changes coming to the WordPress Editor with Gutenberg. I hope this overview will give you some additional information about the coming roll-out of Gutenberg as well.
As you read Steph’s overview keep in mind that the VIP and regular WordPress.com platforms are very different, with different support networks, but also that the regular WordPress.com platform has far fewer customization needs or options.
The New WordPress Editor: What You Need to Know about Gutenberg
In 2018, WordPress will modernize, streamline, and simplify the content creation experience with Gutenberg. It represents the biggest change to the WordPress user experience in several years. In fact, in the State Of The Word 2017 Matt Mullenweg described its enduring importance as “the editor for the next twelve years.”
N.B. If you’d like to try out the Gutenberg plugin, but don’t have a standalone WP.org install handy, you can set up a temporary site on https://poopy.life and then install the Gutenberg plugin from the WP Admin plugin dashboard. Feedback is welcome on Github.
