Gutenberg Migration Guide
This repository documents WordPress Classic Editor customization points and their Gutenberg equivalents (if such exist). Its goal is to help WordPress developers update their plugins and themes for Gutenberg compatibility.
This README.md provides an overview to all impacted hooks (actions and filters) and TinyMCE features. Each item then has an extended document with an overview, examples of existing usage, and documentation for its Gutenberg equivalent (if any).
For the full history, see WordPress/gutenberg#4151. Please open an issue to suggest new hooks, usage examples, or other ideas for improvement.
