Release 0.3.7 - August 16 2013
------------------------------

* Added :func:`write_boolean()` function to write Excel boolean values. Issue
  #37. Also added explicit handling of Python bool values to the

  conversion of numbers in strings to numbers. The previous behaviour can be
  obtained by setting the constructor option to True.

  allow a default date format string to be set. Issue #5.
