[dependabot]

Bumps xlsxwriter from 3.2.5 to 3.2.9.

Changelog

Sourced from xlsxwriter's changelog.

Release 3.2.9 - September 16 2025

• Removed the py.typed file since it was causing a lot of downstream CI failures where consumers weren't handling the xlsxwriter types correctly or taking them into account.

  The file will be re-added once the xlsxwriter typing is more comprehensive.

Release 3.2.8 - September 14 2025

• Fixed mypy implicit export error caused by the Workbook() type annotations changes in v3.2.7 and v3.2.6.

  :issue:1154.

Release 3.2.7 - September 13 2025

• Fixed typing issue in Workbook() constructor.

  :issue:1152.

Release 3.2.6 - September 12 2025

• Added an option to position custom data labels in the same way that the data labels can be positioned for the entire series.

  :feature:1147.

• Add border, fill, gradient and pattern formatting options for chart titles and also chart axis titles.

  :feature:957.

• Add additional type annotations. This is an ongoing refactoring.

  :feature:1123.
