+* License::getLicenses has been deprecated; use License::getLines instead.
+* The driver 'mysql' for MySQL, deprecated in MediaWiki 1.30, has been removed.
+ The driver has been deprecated since PHP 5.5 and was removed in PHP 7.0. The
+ default driver for MySQL has been 'mysqli' since MediaWiki 1.22.
+* The following properties of PreparedEdit were deprecated in 1.21 and have been removed:
+ * PreparedEdit->newText
+ * PreparedEdit->oldText
+ * PreparedEdit->pst
+* QuickTemplate::setRef() was deprecated in favour of QuickTemplate::set().
+ Setting template variables by reference allowed violating the principle of data being
+ immutable once added to the skin template. In practice, this method was not being
+ used for that. Rather, setRef() existed as memory optimisation for PHP 4.
+* Passing false to ParserOptions::setWrapOutputClass() is deprecated. Use the
+ 'unwrap' transform to ParserOutput::getText() instead.
