Feature description

The AMP Stories editor currently requires at least Gutenberg 5.9 due to some of the JS dependencies in the editor. Also, we require at least WordPress 5.0, even when the Gutenberg plugin is installed.

Now that WordPress 5.3 is around the corner which includes Gutenberg 6.6, we should adjust the requirements in \AMP_Story_Post_Type::has_required_block_capabilities() accordingly:

To make maintenance and support easier, I suggest the following:

• WordPress 5.3+ or
• Gutenberg 6.6+

Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• The editor should be accessible on WordPress 5.3 RC 1 or higher, without requiring the Gutenberg plugin
• If the WordPress version is older than WordPress 5.3, it should require the latest version of Gutenberg to be installed (6.6 as of this writing).

Implementation brief

• Bump REQUIRED_GUTENBERG_VERSION
• Make the requirements check pass for WordPress 5.3 RC and higher
• Adjust inline documentation where necessary

QA testing instructions

1. Check that you're using WordPress 5.3 RC
2. Disable Gutenberg plugin
3. Verify that the story editor is still functioning.
