+   * Ensure a recent version of Math::Complex in the test files that use that

+
+   * Improve code so subclassing works better.

+
+   * Misellaneous modernizations.

+   * This release closes CPAN RT ##104334 and #109353.

+All methods return new objects, so, for example, '$X->add($Y)' does not
+modify '$X'.
+
+    $X -> add($Y);         # $X not modified; output is lost
+    $X = $X -> add($Y);    # this works
+
+Some operators are overloaded (see OVERLOADING) and allow the operand to be
+modified directly.
+
+    $X = $X + $Y;          # this works
+    $X += $Y;              # so does this
