1.1.9 October 24 2024

• Fix minor pointer/value error in lxw_name_to_row() and lxw_name_to_col()
  utility functions.

1.1.8 July 31 2024

• Added support for embedding images into worksheets with
  worksheet_embed_image().

  This can be useful if you are building up a spreadsheet of products with a
  column of images for each product. Embedded images move with the cell so they
  can be used in worksheet tables or data ranges that will be sorted or
  filtered.

  This functionality is the equivalent of Excel's menu option to insert an image
  using the option to "Place in Cell" which is available in Excel 365 versions
  from 2023 onwards.

  • Failure on 32bit architectures #441
