+ ** Parsing of Command-style Functions.
+
+    Octave now parses command-style functions without needing to first
+    declare them with "mark_as_command".  The rules for recognizing a
+    command-style function calls are
+
+      * A command must appear as the first word in a statement,
+        followed by a space.
+
+      * The first character after the space must not be '=' or '('
+
+      * The next token after the space must not look like a binary
+        operator.
+
+    These rules should be mostly compatible with the way Matlab parses
+    command-style function calls and allow users to define commands in
+    .m files without having to mark them as commands.
+
+    Note that previous versions of Octave allowed expressions like
+
+      x = load -text foo.dat
+
+    but an expression like this will now generate a parse error.  In
+    order to assign the value returned by a function to a variable,
+    you must use the normal function call syntax:
+
+      x = load ("-text", "foo.dat");
+
  ** Block comments.
 
-    Commented code can be between matching "%{" and "%}" markers, even
-    if the commented code spans several line.  This allows blocks code
-    to be commented, without needing to comment each line.  For
-    example,
+    Commented code can be between matching "#{" and "#}" or "%{" and
+    "%}" markers, even if the commented code spans several line.  This
+    allows blocks code to be commented, without needing to comment
+    each line.  For example,
 
-    function y = func (x)
-      y = 2 * x;
-    %{
-      y += 1;
-    %}
+    function [s, t] = func (x, y)
+      s = 2 * x;
+    #{
+      s *= y;
+      t = y + x;
+    #}
     endfunction
 
-    the line "y += 1;" will not be executed.
+    the lines "s *= y;" and "t = y + x" will not be executed.
