     + New feature/improvement.
     - Removed/deprecated feature.
     ! Bug fix.


0.63 December 19 2012

    + Added Chart data tools such as:
          Error Bars
          Up-Down Bars
          High-Low Lines
          Drop Lines.
      See the chart_data_tool.pl example.


0.62 December 12 2012

    + Added option for adding a data table to a Chart X-axis.
      See output from chart_data_table.pl example.


0.61 December 11 2012

    + Allow a cell url string to be over written with a number or formula
      using a second write() call to the same cell. The url remains intact.
      Issue #48.

    + Added set_default_row() method to set worksheet default values for
      rows.

    + Added Chart set_size() method to set the chart dimensions.


0.60 December 5 2012

    + Added Excel form buttons via the worksheet insert_button() method.
      This allows the user to tie the button to an embedded macro imported
      using add_vba_project(). 
      The portal to the dungeon dimensions is now fully open.

    ! Fix escaping of special character in URLs to write_url(). 
      Issue #45.

    ! Fix for 0 access/modification date on vbaProject.bin files extracted
      using extract_vba. The date isn't generally set correctly in the
      source xlsm file but this caused issues on Windows.


0.59 November 26 2012

    + Added macro support via VBA projects extracted from existing Excel
      xlsm files. User defined functions can be called from worksheets
      and macros can be called by the user but they cannot, currently,
      be linked to form elements such as buttons.


0.58 November 23 2012

    + Added chart area and plot area formatting.


0.57 November 21 2012

    + Add major and minor axis chart gridline formatting.


0.56 November 18 2012

    ! Fix for issue where chart creation order had to be the same
      as the insertion order or charts would be out of sync.
      Frederic Claude Sievert and Hurricup. Issue #42.

    ! Fixed issue where gridlines didn't work in Scatter and Stock
      charts. Issue #41.

    ! Fixed default XML encoding to avoid/solve various issues with XML
      encoding created by the XML changes in version 0.51. Issue #43.


0.55 November 10 2012

    + Added Sparklines.

    ! Fix for issue with "begins with" and "ends with" Conditional
      Formatting. Issue #40.


0.54 November 5 2012

    + Added font manipulation to Charts.

    + Added number formats to Chart axes.

    + Added Radar Charts.

    ! Fix for XML encoding in write_url() internal/external 
      links. Issue #37.


0.53 October 10 2012

    ! Fix for broken MANIFEST file.


0.52 October 9 2012

    ! Added dependency on Date::Calc to xl_parse_date.t test.
      Closes #30 and RT#79790.

    ! Fix for XML encoding of URLs. Closes #31.

    + Refactored XMLWriter into a single class. This breaks the last
      remaining ties to XML::Writer to allow for future additions
      and optimisations. Renamed methods for consistency.


0.51 September 16 2012

    + Speed optimisations.

      This release contains a series of optimisations aimed
      at increasing the speed of Excel::Writer::XLSX. The
      overall improvement is around 66%.
      See the SPEED AND MEMORY USAGE section of the documentation.

    + Memory usage optimisations.

      This fixes an issue where the memory used for the worksheet
      data tables was freed but then brought back into usage due
      to the use of an array as the base data structure. This
      meant that the memory usage still continued to grow with
      large row counts.


    ! Added warning about Excel limit to 65,530 urls per worksheet.

    ! Limit URLs to Excel's limit of 255 chars. Fixes Issue #26.

    ! Fix for whitespace in urls. Fixes Issue #25.

    ! Fix for solid fill of type 'none' is chart series.
      Closes issue #27 reported on Stack Overflow.

    ! Modified write_array_formula() to apply format over full range.
      Fixes issue #18.

    ! Fix for issue with chart formula referring to non-existent sheet name.
      It is now a fatal error to specify a chart series formula that
      refers to an non-existent worksheet name. Fixes issue #17.


0.50 September 9 2012

     + Added option to add secondary axes to charts.
       Thanks to Eric Johnson and to Foxtons for sponsoring the work.

     + Added add_table() method to add Excel tables to worksheets.

     ! Fix for right/left auto shape connection when destination
       is left of source shape. Thanks to Dave Clarke for fix.

     ! Fix for issue #16. Format::copy() method not protecting values.
       The Format copy() method over-writes certain new properties that
       weren't in Spreadsheet::WriteExcel. This fixes the issue by
       storing and restoring the properties during copy.

     ! Fix for issue #15: write_url with local sub directory.
       Local sub-directories were incorrectly treated as
       file:// external.

     ! Fix for for issue #14: Non-numeric data in chart value axes
       are now converted to zero in chart data cache, as required
       by Excel.

    + Added show_blanks_as() chart method to control the display of
      blank data.

      shared with cell formats.
      Reported by Patryk Kwiatkowski.

    ! Fix for xl_parse_time() with hours > 24. Github issue #11.

      Krishna Rajendran.
