+* The following methods related to caching of half-parsed HTML were deprecated:
+ * Parser::serializeHalfParsedText()
+ * Parser::unserializeHalfParsedText()
+ * Parser::isValidHalfParsedText()
+ * StripState::getSubState()
+ * StripState::merge()
+* The "free" class is now only applied to unbracketed URLs in wikitext. Links
+ written using square brackets will get the class "text" not "free".
