(official post) (https://make.wordpress.org/core/2025/10/08/whats-new-in-gutenberg-21-8-08-october/) - Gutenberg plugin (WordPress.org) (https://wordpress.org/plugins/gutenberg/) - Block Editor Handbook (https://developer.wordpress.org/block-editor/) ## 🗣️ Paraphrase - Paragraph A - Gutenberg 21.8 ships a new editor UI to hide blocks that won’t appear on the frontend, improving design accuracy and setting up future visibility granularity. - Paragraph B - The release also upgrades Time To Read (range/word-count, migration), improves Accordion accessibility/structure, and refines Block Comments’ UX and editing flow. ## 📰 Newsletter - Gutenberg 21.8 lands with the first Block Visibility UI—now the editor won’t mislead you when a block won’t render on the frontend. Time To Read gains range/word-count options (with migrations), Accordion gets accessibility and UI polish, and Block Comments sees notable UX upgrades. Kick the tires via the Gutenberg plugin and review the Block Editor Handbook for updated patterns.
