@ckeditor/ckeditor5-build-classic 43.1.0

on Node.js NPM

We are happy to announce the release of CKEditor 5 v43.1.0.

Release highlights

This release includes important bug fixes and enhancements for the editor:

• Block merge fields: In contrast to regular, inline merge fields, the block merge fields are designed to represent complex, block-level structures, such as a dynamically generated table, a row of products, or a personalized call-to-action segment. Block merge fields are supposed to be replaced by arbitrary HTML data when the document template is post-processed or exported to a PDF or Word file.

• Nested dropdown menus: this release introduces a new UI component: nested dropdown menus. They can be used by feature developers to easily provide an advanced user interface where UI elements are organized into a nested menu structure.

• Customizable accessible label: You can now configure the label for the accessible editable area through the editor settings, ensuring it fits your system’s needs.

• Improved table and cell border controls: It is now easier to manage both table and cell borders. The table user interface now clearly indicates the default border settings, allowing you to set “no borders” (None) for tables and cells without any additional configuration.

  ⚠️ In some cases this update may lead to data changes in the tables’ HTML markup when the editor loads them. However, visually nothing will change, and the experience will be the same.

The full list of enhancements can be found below.

MINOR BREAKING CHANGES ℹ️

• Reverted config.sanitizeHtml. In v43.0.0 we made a decision to move config.htmlEmbed.sanitizeHtml to a top-level property config.sanitizeHtml. However, we realized that it was a wrong decision to expose such a sensitive property in a top-level configuration property. Starting with v43.1.0 you should again use config.htmlEmbed.sanitizeHtml and/or config.mergeFields.sanitizeHtml. The editor will throw an error if config.sanitizeHtml is used. See the {@link
  updating/update-to-43#reverted-recently-introduced-configsanitizehtml migration guide} for additional context behind this decision.
• ai: The structure and presentation of the list of AI commands in the toolbar have changed (a flat filtered list is now a nested menu). Additionally, if your integration customizes this user interface, please ensure your integration code is up-to-date.
• ui: The default [aria-label] provided by InlineEditableUIView is now 'Rich Text Editor. Editing area: [root name]' (previously: 'Editor editing area: [root name]'). You can use the options.label constructor property to adjust the label.
