+=======================================================
+Breaking: #72667 - RTE: Unused internal methods removed
+=======================================================
+
+Description
+===========
+
+The HTML parsing features for the Rich Text Editor feature related to the xhtml_cleaning were removed. The following now obsolete methods are
+removed as well:
+
+* ``HtmlParser->checkTagTypeCounts()``
+* ``HtmlParser->unprotectTags()``
+* ``HtmlParser->get_tag_attributes_classic()``
+* ``HtmlParser->cleanFontTags()``
+* ``HtmlParser->indentLines()``
+
+Additionally, the third parameter for the method ``HtmlParser->getAllParts()`` was removed as well, resulting that the method will always include
+the parsed tags in the result set.
+
+
+Impact
+======
+
+Calling any of the methods will result in a fatal PHP error.
+
+
+Affected Installations
+======================
+
+Any installation which uses a third-party extension that modifies the HtmlParsing via PHP.
