v0.2.90 Release Notes

This release adds cell background color extraction via colors_map, including conditional formatting support when running with Excel COM.

Highlights

• colors_map: SheetData now includes background color locations keyed by hex color strings.
• COM display colors: in COM environments, extraction reads DisplayFormat.Interior to capture conditional formatting colors.
• ColorsOptions: configure color extraction with include_default_background and ignore_colors (normalized hex keys).
• Verbose mode: mode="verbose" now enables colors_map extraction by default.
• Tests: added coverage for default background exclusion and ignore lists.

Compatibility Notes

• Non-COM environments still extract colors via openpyxl, without conditional formatting evaluation.
• ignore_colors is applied during extraction, reducing payload size early.
