+The HTML tokenizer now conforms fully to HTML5. Several non-standard
+syntax warnings were removed. Note that HTML5 tree construction isn't
+implemented yet.
+
+Binary compatibility is restricted to versions 2.14 or newer. On ELF
+systems, the soname was bumped from libxml2.so.2 to libxml2.so.16.
 
 The serialization API will now take user-provided or default encodings
 into account when serializing attribute values, matching the
 serialization of text and avoiding unnecessary escaping.
 
+The XML parser won't try to merge consecutive CDATA sections as before
+to align with web standards. Each CDATA section will create exactly one
+node or SAX callback.

 Support for RELAX NG can now be disabled with a new configuration
 option independently of XML Schemas support. It is still enabled by
 default.
