Release 1.1.2 - October 20 2018
-------------------------------
* Fix for issue where ``in_memory`` files weren't compressed.
Issue `#573 <https://github.com/jmcnamara/XlsxWriter/issues/573>`_.
* Fix ``write()`` so that it handles array formulas as documented.
Issue `#418 <https://github.com/jmcnamara/XlsxWriter/issues/418>`_.
* Fix for issue with special characters in worksheet table functions.
Issue `#442 <https://github.com/jmcnamara/XlsxWriter/issues/442>`_.
* Added warnings for input issues in :func:`write_rich_string()` such as blank
strings, double formats or insufficient parameters.
Issue `#425 <https://github.com/jmcnamara/XlsxWriter/issues/425>`_.
Release 1.1.1 - September 22 2018
---------------------------------
* Added comment font name and size options.
Issue `#201 <https://github.com/jmcnamara/XlsxWriter/issues/201>`_.
* Fix for issue when using text boxes in the same workbook as a chartsheet.
Issue `#420 <https://github.com/jmcnamara/XlsxWriter/issues/420>`_.
Release 1.1.0 - September 2 2018
--------------------------------
* Added functionality to align chart category axis labels. See the
``label_align`` property of the :func:`set_x_axis()` method.
* Added worksheet :func:`hide_row_col_headers()` method to turn off worksheet
row and column headings.
Issue `#480 <https://github.com/jmcnamara/XlsxWriter/issues/480>`_.
* Added the :func:`set_tab_ratio()` method to set the ratio between the
worksheet tabs and the horizontal slider.
Issue `#481 <https://github.com/jmcnamara/XlsxWriter/issues/481>`_.
* Fixed issue with icon conditional formats when the values were zero.
Issue `#565 <https://github.com/jmcnamara/XlsxWriter/issues/565>`_.
Release 1.0.9 - August 27 2018
------------------------------
* Fix for issue with formulas quoted as strings in conditional formats,
introduced in version 1.0.7.
Issue `#564 <https://github.com/jmcnamara/XlsxWriter/issues/564>`_.
Release 1.0.8 - August 27 2018
------------------------------
* Added named exceptions to XlsxWriter. See :ref:`exceptions`.
* Removed the implicit :func:`close()` in the destructor since it wasn't
guaranteed to work correctly and raised a confusing exception when any other
exception was triggered. **Note that this is a backward incompatible
change.** The ``with`` context manager is a better way to close
automatically, see :func:`close()`.
* Added border, fill, pattern and gradient formatting options to
:func:`set_legend()`.
Issue `#545 <https://github.com/jmcnamara/XlsxWriter/issues/545>`_.

:ref:`ex_inheritance1` and :ref:`ex_inheritance2`.
* Added support for WMF and EMF image formats to the Worksheet
:func:`add_image` method.
Release 1.0.4 - April 14 2018
-----------------------------
* Set the xlsx internal file member datetimes to 1980-01-01 00:00:00 like
Excel so that apps can produce a consistent binary file once the workbook
:func:`set_properties` ``created`` date is set.
Pull request `#495 <https://github.com/jmcnamara/XlsxWriter/pull/495>`_.
* Fix for jpeg images that reported unknown height/width due to unusual SOF markers.
Issue `#506 <https://github.com/jmcnamara/XlsxWriter/issues/506>`_.

work.
Feature request `#455 <https://github.com/jmcnamara/XlsxWriter/issues/455>`_.
Release 1.0.1 - October 14 2017
-------------------------------
* Changed default :func:`write_url` format to the Excel hyperlink style so that
it changes when the theme is changed and also so that it indicates that the
link has been clicked.
Feature request `#455 <https://github.com/jmcnamara/XlsxWriter/issues/455>`_.
