v18.0.0

MAJOR BREAKING CHANGES

• EditingController requires an instance of StylesProcessor in its constructor.
• DataController requires an instance of StylesProcessor in its constructor.
• DomConverter, HtmlDataProcessor and XmlDataProcessor require an instance of the view document in their constructors.
• The View class requires an instance of StylesProcessor as its first argument.
• The createViewElementFromHighlightDescriptor() function that is exported by src/conversion/downcasthelpers.js file requires an instance of the view document as its first argument.
• Method view.Document#addStyleProcessorRules() has been moved to the DataController class.
• The #document getter was removed from model nodes. Only the root element holds the reference to the model document. For attached nodes, use node.root.document to access it.

MINOR BREAKING CHANGES

• DataController does not accept the data processor instance any more.

Features

• Implemented the model and view Range#getContainedElement() methods. Closes ckeditor/ckeditor5#6364. (8fb1efa)

Bug fixes

• Fixed renderer bug causing editor crash in a range of scenarios involving reusing DOM elements. Closes ckeditor/ckeditor5#6092. (67884da)

Other changes

• DataController will now use a single instance of the view document for all its operations (DataController#viewDocument). Closes ckeditor/ckeditor5#6381. (851bac6)
• Document#version is no longer read-only. (968b193)
• StylesProcessor rules will not be stored in a singleton, which made them shared between editor instances. In order to allow binding a styles processor instance to a specific view document, we had to replace a dynamic #document property in view nodes with a static one, set upon node creation. Closes ckeditor/ckeditor5#6091. (0e2f02e)
• Introduced support for multi-range selections. Closes ckeditor/ckeditor5#6116. (ffce577)
