**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 after the first release in 2021 (probably in January
2021). No new features or fixes for Python 2.7 will be added to XlsxWriter
after that date/release.
Release 1.3.0 - July 30 2020
----------------------------
* Added support for custom chart :ref:`custom data labels
<chart_series_option_custom_data_labels>`.
Feature request `#343 <https://github.com/jmcnamara/XlsxWriter/issues/343>`_.
Release 1.2.9 - May 29 2020
---------------------------
* Added support for ``stacked`` and ``percent_stacked`` Line charts.
Release 1.2.8 - February 22 2020
--------------------------------
* Fix for issue where duplicate images with hyperlinks weren't handled
correctly.
Issue `#686 <https://github.com/jmcnamara/XlsxWriter/issues/686>`_.
* Removed ``ReservedWorksheetName`` exception which was used with the reserved
worksheet name "History" since this name is allowed in some Excel variants.
Issue `#688 <https://github.com/jmcnamara/XlsxWriter/issues/688>`_.
* Fix for worksheet objects (charts, images and textboxes) that are inserted
with an offset that starts in a hidden cell.
Issue `#676 <https://github.com/jmcnamara/XlsxWriter/issues/676>`_.
* Fix to allow handling of NoneType in :func:`add_write_handler`.
Issue `#677 <https://github.com/jmcnamara/XlsxWriter/issues/677>`_.
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`.
* Added note to :func:`protect()` about how it is possible to encrypt an
XlsxWriter file using a third party, cross platform, open source tool called
`msoffice-crypt <https://github.com/herumi/msoffice>`_.
Release 1.2.6 - November 15 2019
--------------------------------
* Added option to remove style from worksheet tables.
Feature request `#670 <https://github.com/jmcnamara/XlsxWriter/issues/670>`_.
Release 1.2.5 - November 10 2019
--------------------------------
* Added option to add hyperlinks to textboxes. See :ref:`textbox_hyperlink`.
Feature request `#419 <https://github.com/jmcnamara/XlsxWriter/issues/419>`_.
Release 1.2.4 - November 9 2019
-------------------------------
* Added option to link textbox text from a cell. See :ref:`textbox_textlink`.
Feature request `#516 <https://github.com/jmcnamara/XlsxWriter/issues/516>`_.
* Added option to rotate text in a textbox. See
:ref:`textbox_formatting_rotation`.
Feature request `#638 <https://github.com/jmcnamara/XlsxWriter/issues/638>`_.
Release 1.2.3 - November 7 2019
-------------------------------
* Increased allowable worksheet url length from 255 to 2079 characters, as
supported in more recent versions of Excel. A lower or user defined limit
can be set via the ``max_url_length`` property in the :func:`Workbook`
constructor.
* Fixed several issues with hyperlinks in worksheet images.
Release 1.2.2 - October 16 2019
-------------------------------
* Fixed Python 3.8.0 warnings.
Issue `#660 <https://github.com/jmcnamara/XlsxWriter/issues/660>`_.
Release 1.2.1 - September 14 2019
---------------------------------
* Added the :func:`add_write_handler` method to allow user defined types to be
handled by the :func:`write` method. See :ref:`writing_user_types` for more
information.
Feature request `#631 <https://github.com/jmcnamara/XlsxWriter/issues/631>`_.
* Add support for East Asian vertical fonts in charts.
Feature request `#648 <https://github.com/jmcnamara/XlsxWriter/issues/648>`_.
Release 1.2.0 - August 26 2019
------------------------------
* Refactored exception handling around the workbook file :func:`close()`
method to allow exceptions to be caught and handled. See
:ref:`ex_check_close`. Also refactored the code to clean up temp files in
the event of an exception.
Issues `#471 <https://github.com/jmcnamara/XlsxWriter/issues/471>`_
and `#647 <https://github.com/jmcnamara/XlsxWriter/issues/647>`_.
* Added the option to allow chart fonts to be rotated to 270 degrees
to give a stacked orientation. See :ref:`chart_fonts`.
Issue `#648 <https://github.com/jmcnamara/XlsxWriter/issues/648>`_.
Release 1.1.9 - August 19 2019
------------------------------
* Another fix for issues where zipfile.py raises "ZIP does not support
timestamps before 1980" exception.
Issue `#651 <https://github.com/jmcnamara/XlsxWriter/issues/651>`_.
Release 1.1.8 - May 5 2019
--------------------------
* Added ability to combine Doughnut and Pie charts.
* Added gauge chart example which is a combination of a Doughnut and a Pie
chart. See :ref:`ex_chart_gauge`.
Release 1.1.7 - April 20 2019
-----------------------------
* Added docs on :ref:`object_position`.
* Added fix for sizing of cell comment boxes when they cross columns/rows that
have size changes that occur after the comment is written.
Issue `#403 <https://github.com/jmcnamara/XlsxWriter/issues/403>`_ and
issue `#312 <https://github.com/jmcnamara/XlsxWriter/issues/312>`_.
* Added fix for the sizing of worksheet objects (images, charts, textboxes)
when the underlying cell sizes have changed and the "object_position"
parameter has been set to 1 "Move and size with cells". An additional mode 4
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>`_.
Release 1.1.6 - April 7 2019
----------------------------
* Fixed issue where images that started in hidden rows/columns weren't placed
correctly in the worksheet.
Issue `#613 <https://github.com/jmcnamara/XlsxWriter/issues/613>`_.
* Fixed the mime-type reported by system ``file(1)``. The mime-type reported
by "file --mime-type"/magic was incorrect for XlsxWriter files since it
expected the ``[Content_types]`` to be the first file in the zip container.
Issue `#614 <https://github.com/jmcnamara/XlsxWriter/issues/614>`_.
Release 1.1.5 - February 22 2019
--------------------------------
* This version removes support for end of life Pythons 2.5, 2.6, 3.1, 3.2 and

Release 0.3.7 - August 16 2013
------------------------------
* Added :func:`write_boolean()` function to write Excel boolean values. Feature request
`#37 <https://github.com/jmcnamara/XlsxWriter/issues/37>`_. Also added
explicit handling of Python bool values to the :func:`write()` function.
* Changed :func:`Workbook` constructor option
``strings_to_numbers`` default option to False so that there is no implicit
conversion of numbers in strings to numbers. The previous behavior can be
obtained by setting the constructor option to True.
**Note** This is a backward incompatibility.
