This release introduces drag and drop capabilities for sorting blocks, various refinements to the block visual interface (including a label with block type identifier) and extensibility APIs, plus a lot of bug fixes. Thanks to everyone who contributed for all the ongoing efforts!

2.6 🐉 💧

• Add drag and drop functionality to reorder blocks (in addition to arrow movers).
• Improve side UI around nested groups and introduce a block name label on hover.
• Focus the block inspector automatically when a block is selected.
  
• Allow extending auto-completers via filters — this also exposes the "user" auto-complete to all RichText component instances, making it much easier to leverage for external blocks.
• Use debounced search request in user auto-complete mechanism improving the experience of mentioning in sites with more than 100 users.

#core-editor, #editor, #gutenberg

This release iterates further on some design and writing flow details — lighter up/down movers, engaging the UI-less focus mode more often, etc. It also brings many extensibility API improvements, exposing internal editor state through selectors, enhancements to the meta-box handling, and implements the "Copy All" button as if it was a plugin as an example of how to leverage native hooks.

2.1 🦔

• Iterate on the design of up/down arrows and how focus is managed. This seeks to further reduce the visual and cognitive weight of the up/down movers.
• Show immediate visual feedback when dragging and dropping images into the editor. (Expands on the previous release work.)
• Expose state through data module using selectors. This is an important piece of the extensibility puzzle.
• New button outline and focus styles.
• Show original block icon after converting to reusable block. Also hides the generic reusable block from inserters. This moves data logic out of the inserter.
• Introduce a migration function for block versioning.
• Add HTML handler to dropzone. Allows drag and dropping images from other web pages directly.
• Trigger typing mode when ENTER or BACKSPACE are pressed. This improves the writing flow but engaging the UI-less mode more frequently.
  

Other changes:

• Added ability to align the text content of a cover image to the right, left, or center of the image.
• Refactor CopyContentButton as a core extension to illustrate how to add functionality to the editor outside of blocks.
• Allow collapsing/sorting meta-boxes panels.
  
• Remove dirty-checking from meta-boxes state, fixes issues with default values and updating certain text fields.
• Defer registration of all core blocks until editor loads. Improves ability to hook into registerBlockType.
• Only trigger select block action when block is unselected.
• Try new markup for Galleries using lists.
• New: trying a Subheading block.
• Reduce sibling inserter initial height.
• Force an update when a new filter is added or removed while using withFilters higher-order component. This improves the rendering flow of filters.
  
• Refactor the MediaUploadButton to be agnostic to its rendered UI.
• Change "size" label to "level" in Heading block settings.
• Remove breaking spaces logic on List block.
• Update progress button color state based on theme used.
• Update Video block description.
• Refactor the multi-selection behavior to dispatch the multi-selection start action only after the cursor begins to move after a mousedown event.
• Avoid persisting mobile and publish sidebars.
• Move drag handling to instance-bound handler.
• Remove "Open in new window" link option.
• Use username slug instead of name and remove ephemeral link from it.
  
• Ensure isLoading set to false after request error.
• Allow copying individual text from a block that is not purely text without copying the whole block.
• Match consistency of tooltip text with Classic Editor.
• Fix issue with Lists having additional lines when used in a reusable block.
• Fix errors when adding duplicate tags.
• Fix inconsistency with applyOrUnset().
• Fix incorrect display when loading a saved block with no content.
• Fix issue where black rectangle would briefly blink on new paragraphs.

• Force wp-api.js to use HTTP/1.0 for better compatibility.
• Avoid the deprecated (from 5.0 to 5.2) is_a() function.
• Remove unused dependency.
• Update contributing instructions with steps.
• Consistency cleanup in doc return statements.
• Include how to assign a template to a default Post Type in the documentation. Also add more context to the code.
• Improve incremental development build performance by only minimizing -rtl files for production builds.

• Add new page explaining how to create a block using WP-CLI.

What's next?

As we approach the final stages of features, we are looking at finalizing the nested blocks interface (with its own Columns component), some remaining important extensibility hooks for plugins, and adding drag-drop functionality for moving and inserting blocks. ⛰
