Gutenberg 5.1.0: gutenberg_can_edit_post_type is deprecated since version 5.0.0! Use use_block_editor_for_post_type instead.

Workarounds

• deactivate classic-editor
• deactivate Gutenberg
• revert to Gutenberg v5.0 or earlier
• define( 'WP_DEBUG', false );

Interesting that the message says deprecated since 5.0.0 but there's no message from that version!

Should be fixes as of 45ff568.

It still checks if the function exists before using it to support older Gutenberg versions (it that needed?).
