**Deprecation Notice**: Python 2.7 reached the end of its life on January 1st,

2020 and is no longer being supported in the community. XlsxWriter support for

Python 2.7 will end by mid-year 2021 (probably in July 2021). No new features

or fixes for Python 2.7 will be added to XlsxWriter after that date/release.

Release 1.4.0 - April 23 2021

the data labels in the series.

digest to avoid issues on operating systems such as Red Hat in FIPS mode

which don't support MD5 for security reasons.

Release 1.2.7 - December 23 2019

--------------------------------

* Fix for duplicate images being copied to an XlsxWriter file. Excel uses an

optimization where it only stores one copy of a repeated/duplicate image in

a workbook. XlsxWriter didn't do this which meant that the file size would

increase when then was a large number of repeated images. This release fixes

that issue and replicates Excel's behavior.

Issue `#615 <https://github.com/jmcnamara/XlsxWriter/issues/615>`_.

* Added documentation on :ref:`num_format_categories` and

:ref:`num_format_locale`.

the event of an exception.

Issues `#471 <https://github.com/jmcnamara/XlsxWriter/issues/471>`_

and `#647 <https://github.com/jmcnamara/XlsxWriter/issues/647>`_.

to give a stacked orientation. See :ref:`chart_fonts`.

has been added to simulate inserting the object in hidden rows.

Issue `#618 <https://github.com/jmcnamara/XlsxWriter/issues/618>`_.

* Added object positioning for charts and textboxes, it was already supported

for images. Note, the parameter is now called ``object_position``. The

previous parameter name ``positioning`` is deprecated but still supported

for images.

Issue `#568 <https://github.com/jmcnamara/XlsxWriter/issues/568>`_.

----------------------------

correctly in the worksheet.

Issue `#613 <https://github.com/jmcnamara/XlsxWriter/issues/613>`_.

------------------------------

* Added named exceptions to XlsxWriter. See :ref:`exceptions`.
