* This is the last XlsxWriter release to support Python 2. From now bug fixes
  and new features will only be available for Python 3. The deprecation notice

  Python community support for Python 2 ended in January 2020. Downloads of
  XlsxWriter for Python 2 is currently less than 6% of all downloads of the
  library, and decreasing month by month.

  Python 2 users should still be able to install versions of XlsxWriter up to
  this release but not any releases afterwards.
