Changelog

6.7.0 - 2023-08-30

Added

• New help_accessibility option displays the keyboard shortcut to open the in-application help in the status bar.
• Added a new InsertNewBlockBefore command which inserts an empty block before the block containing the current selection.
• Added a new InsertNewBlockAfter command which inserts an empty block after the block containing the current selection.

Improved

• Adding a newline after a table would, in some specific cases, not work.
• Menus now have a slight margin at the top and bottom to more clearly separate them from the frame edge.
• Updated More toolbar button tooltip text from More…​ to Reveal or hide additional toolbar items.
• Where multiple case sensitive variants of a translation key are provided, they will now all be preserved in the translation object instead of just the lowercase variant.
• Improved screen reader announcements of the column and row selection in the grid presented by the Table menu and toolbar item.
• Improved the keyboard focus visibility for links inside dialogs.

Changed

• Change UndoLevelType from enum to union type so that it is easier to use.
• The pattern replacement removed spaces if they were contained within a tag that only contained a space and the text to replace.
• If loading content CSS takes more than 500ms, the editor will be set to an in progress state until the CSS is ready.

Fixed

• Applying an ordered or unordered list to a selected checklist incorrectly turned the list into paragraphs.
• Returning an empty string in a custom context menu update function resulted in a small white line appearing on right-click and the browser-native context menu would not present.
• For sufficiently long URLs and sufficiently wide windows, URL autocompletion hid middle portions of the URL from view.
• Numeric input in toolbar items did not disable when a switching from edit to read-only mode.
• The Quick Toolbars plugin showed text alignment buttons on pagebreaks.
• Creating lists in empty blocks sometimes, and incorrectly, converted adjacent block elements into list items.
• Creating a list from multiple
  elements only created a partial list.
• Tab navigation incorrectly stopped around iframe dialog components.
• It was possible to delete the sole empty block immediately before a <details> element if it was nested within another <details> element.
• Deleting <li> elements that only contained <br> tags sometimes caused a crash.
• It was possible to remove the <summary> element from a <details> element by dragging and dropping.
• It was possible to break <summary> elements if content containing block elements was dragged-and-dropped inside them.
• Contents were not removed from the drag start source if dragging and dropping internally into a transparent block element.
• Using the Media plugin unexpectedly changed <script> tags in the editor body to <image> tags.
• In some circumstances, pressing the Enter key scrolled the entire page.
• The border styles of a table were incorrectly split into a longhand form after table dialog updates.
• Links in Help → Help → Plugins and Help → Help → Version were not navigable by keyboard.
• Fixed the inability to insert content next to the <details> element when it is the first or last content element. Pressing the Up or Down arrow key now inserts a block element before or after the <details> element.
• An empty element with a contenteditable="true" attribute within a noneditable root was deleted when the Backspace key was pressed.
• The color_cols option was not respected when set to the value 5 with a custom color_map specified.
• In Safari on macOS, deleting backwards within a <summary> element removed the entire <details> element if it had no other content.
