  • Paste audio and video files: Users can copy and paste audio and video files from the local file browser, enabling bulk multimedia ingestion for faster content creation.

Bug Fixes

  • #I822860 - Now, the Rich Text Editor QuickToolbar dropdown will open properly in the limited height web view.

  • #I843394 - Now, border-collapse and border-spacing are now included in allowedStyleProps, enabling correct preservation of double borders when pasting tables.

  • Audio and Video saved on the server will no longer be automatically deleted when using keyboard or quick toolbar actions in the editor. This change is necessary because if the audio and video are removed from the server, it would prevent the ability to perform undo/redo actions on them.

  • Solution : To handle audio and video deletions properly, use the afterMediaDelete event to capture the src of the deleted audio and video. Then, send a request to your server to remove the audio and video from storage, ensuring it is only deleted when explicitly intended.

  • #I835102 - Now, the image preview will be shown properly for drag and dropped images in RichTextEditor.

  • #I842908 - Now, the RTL Mode will not hide Left Border of table pasted from Excel in RichTextEditor.

  • #I831960 - Now, the insert link dialog will be visible while scrolling using scrollbar.

  • #I846471 - Now, the bullet list formatting will be preserved after pasting.

  • #I848296 - Now, pasting contents with list and hyperlinks issue has been resolved.

Web Block Editor

Applies To: React, Angular, JavaScript, TypeScript, Vue, ASP.NET Core, and ASP.NET MVC.

Features

  • Collaborative Editing: The Block Editor now supports real-time collaborative editing through the collaborationSettings property, enabling multiple users to work on the same document simultaneously. This feature includes seamless integration with collaboration providers, configuration of the YJS adapter, and cursor awareness using enableAwareness. Active user presence is effectively managed with the users and currentUserId properties, allowing clear identification and visualization of collaborators within the editor.

Breaking Changes

The following API’s have been modified/removed.

  • Now the allowedStyles property in pasteCleanupSettings has been removed.

  • The default Block Editor image saveFormat has been changed from Base64 to Blob. Serialized outputs now generate binary Blob objects, improving performance and reducing payload size.

Blazor Block Editor

Features

  • Now the Block Editor improved the image block with server-side storage support for better asset management. Users can upload images directly from the editor, configure server-side storage for upload operations. Users can use the BlockEditorImageBlock to configure the image related properties (SaveUrl, Path, SaveFormat).

  • Now the Block Editor supports transform block options in the inline toolbar for quick and seamless block conversion. Users can convert blocks between different types (such as paragraph to heading or quote to callout) directly from the inline toolbar, access commonly used block transformations through intuitive controls, and maintain content integrity during the conversion process.

  • Now the Block Editor supports inline code and link support in the inline toolbar to improve code and link formatting capabilities. Users can apply inline code and link formatting to selected text, benefit from inline code styling with syntax highlighting & link addition, and seamlessly combine it with other text formatting options available in the toolbar.
