“Try Gutenberg” is an initiative, currently scheduled for WordPress 4.9.8, to drive more usage of the Gutenberg editor plugin. A while back, I left an offhand comment listing issues I saw as blockers (those that caused data transformation that would be hard to recover from at scale). This comment apparently received more attention than I expected it to, so now we’re partially focused on making sure those blockers are resolved.
And have we been fixing blockers! A non-exhaustive list includes:

The Gutenberg Migration Guide is a crowdsourcing project to document WordPress Classic Editor customization points and their Gutenberg equivalents (if such exist). media_buttons is the quintessential example; whereas you might’ve used this action previously in the Classic Editor to register a button, it no longer exists in Gutenberg and the block inserter is its direct equivalent.
We want the migration guide to be as comprehensive as it can be. This is defined as:
Identifying as many integration points as we can find. For instance, there are already 14 actions / filters listed. Some are commonly used, while others are not. As long as we have a good example for how the integration point is used, it makes sense to include in the guide.
Whenever possible, documenting how feature parity can be achieved with Gutenberg. Some integration points do already have Gutenberg equivalents. Others don’t yet, and that’s alright.
You can help make the migration guide more comprehensive. If you don’t have any examples of your own to include, here are a couple of places you can start looking:
Everyone can contribute to the migration guide, regardless of skill set. All you need to do is open a new GitHub issue and report the incompatibility you’ve found. Screenshots and GIFs are tremendously helpful. If you know the underlying problem, then please include that too. If all you know is that a given plugin’s feature doesn’t work in Gutenberg, no worries; simply open an issue and we can help track down the cause. Identifying examples of breakage are what we need help with most.
Feel free to join #hosting-community in the WordPress.org Slack if you have any questions, etc. Thanks for your help!
Since I last wrote two weeks ago, we’re making progress! Key achievements for Gutenberg and the REST API include:
Support for who=authors was added to GET wp/v2/users, making it possible to accurately query for authors. WordPress, for better or for worse, defines an author as user_level!=0. See WordPress/gutenberg#6361 for the context on why we can’t add this logic client-side (#42202 for WordPress 4.9.6).
Improved performance for the _fields= query parameter (e.g. GET wp/v2/pages?_fields=id,title) by ensuring WordPress core will only process the fields requested for the response. Notably, this helps us avoid running the_content when we don’t need to be (#43874 for WordPress 4.9.7).
Minor enhancements to reflect existing WordPress behaviors:
The “Merge Proposal: REST API” GitHub milestone represents the distance we still need to close. Slowly, steadily, we’re bridging the gap, but we could use your help. Here are some of the issues we’re still working through:
To ensure all necessary data is available to Gutenberg, we’ve settled upon permitting unbounded per_page=-1 REST API requests for authorized users. This landed for GET wp/v2/users (WordPress/gutenberg#6627), is in-progress for GET wp/v2/(pages|blocks) (WordPress/gutenberg#6657), and needs to be addressed for categories, tags, and custom taxonomies. We also need to patch core with this enhancement (#43998 for WordPress 4.9.7?)
Capabilities can’t be processed directly client-side (WordPress/gutenberg#6361), so we’ve introduced a new targetSchema concept to communicate which actions a user can perform. See it in action with wp:action-sticky (WordPress/gutenberg#6529) and wp:action-assign-author (WordPress/gutenberg#6630). There are a few other actions we will need to work out, and then we’ll need to patch core (no ticket yet).
Adam is putting together an improved autosaves implementation (WordPress/gutenberg#6257) that I literally cannot wait to see complete. I’m sure he could use some help testing in the near future.
media_buttons is only one of the many ways the Classic Editor can be customized. Wouldn’t it be great if there was a database covering all of them?
This is where you come in! Take a look through the Gutenberg Migration Guide. For each action, filter, and so on, we’d like to document real-world examples of how they’ve been used. Then, for each of those real-world examples, identify how the feature might be replicated in Gutenberg.
Since announcing the database on March 1st, 70 people have been granted testing status. However, of 5000 total plugins, we’re still at 4139 untested plugins. No companies have stepped up to contribute a significant amount of person-hours.
Of the 861 tested plugins:
219 (25.44%) are compatible.
518 (60.16%) are likely compatible.
25 (2.9%) are likely not compatible.
39 (4.53%) are not compatible.
60 (6.97%) are in “testing”, which means someone started test and abandoned the process.
Notably, this data is largely biased by the “likely compatible” results. For the most part, these are plugins I pre-screened (e.g. caching plugins) prior to March.
In the original data set, 18 (28.125%) of the 64 incompatible and likely incompatible plugins were updated in the four weeks prior to March 1st. This means the majority are on slower development cycles.
Of the 64 incompatible and likely incompatible plugins, the reasons include:
Missing Add Media and TinyMCE buttons (NextGen, WPForms, Formidable, FooGallery, Page Scroll to ID and others).
Missing QuickTag buttons (Quick AdSense).
Meta box doesn’t display at all (Page Links To, Revision Control).
Semi-live preview of SEO title doesn’t work in Gutenberg (All In One SEO).
Custom Short or Long Product Description fields don’t appear at all (WooCommerce).
Featured thumbnail previews aren’t being generated (Auto Post Thumbnail).Whitescreen of death (qTranslate X, CKEditor).
Registers a CPT with editor support that doesn’t include show_in_rest=>true (Portfolio Post Type)
Adds section to Media Library that isn’t displayed in Gutenberg (Add From Server).
Access restriction from plugin not applied in Gutenberg (Advanced Access Manager).
