+26 May 2014
+
+** support expression functions
+
+** beginning-of-defun-function, end-of-defun-function are now set. A
+ "defun" is a generic, package, protected, subprogram, or task spec
+ or body.
+
+** C-c C-s is now bound to ada-goto-previous-pos, which goes to the
+ first position in ada-goto-pos-ring. Most navigation functions set
+ ada-goto-pos-ring. This allows easy navigation back to the start of
+ a cross-reference chain.
+
+** xref tool error handlers no longer show the xref tool buffer; the
+ new Ada menu item 'show xref tool buffer' can be used instead.
+
+** The parser supports more deeply nested case statements.
