If you are tuned into the WordPress world, you've heard one word many times over the last few weeks: Gutenberg.

On stage at WordCamp EU in mid-June, Matt Mullenwegg unveiled the first version of Gutenberg. This is the new editor that Matt hopes will replace the current TinyMCE.

This would be a mind-boggling radical change for WordPress. In recent years, they have developed a legendary reputation for always keeping backward compatability. Gutenberg would probably shatter that reputation. Gutenberg would probably break a lot of existing plugins - many people would not be able to update easily.
