+Deprecation: #24387 - TypoScript option config.xhtmlDoctype=xhtml_2
+===================================================================
+
+See :issue:`24387`
+
+Description
+===========
+
+The TypoScript option `config.xhtmlDoctype = xhtml_2` is marked for removal in CMS 8, due to the W3C decision to
+fully work on HTML5 instead of XHTML2. See http://www.w3.org/MarkUp/ and http://www.w3.org/News/2010.html#entry-8982
+for more details.
+
+
+Affected installations
+======================
+
+Any TYPO3 installation with TypoScript that relies on `config.xhtmlDoctype = xhtml_2`.
+
+Migration
+=========
+
+Use other doctypes like html5 to render the frontend of the TYPO3 site.
