Bugfixes:
  Label cmdstar:   part of the example code was just wrong

  Bug in "introduction=yes" HTML code corrected
  Label atsigns:   mark-up error caused curious HTML output (editorial
		   improvement too)
 +Release dates are now represented in ISO format (yyyy-mm-dd) --
  previously we used the LaTeX format, using solidus instead of hyphen

Future releases:
  There are no current plans for a major release, though work on the
  new web-based version continues.
