- fix: bound SixLabors.Fonts to version range [1.0.0,2.0.0)
- Named range expands upward when deleting its first row, unlike Excel
- LINQ operations (filtering) on IXLColumn [e.g. returned by ColumnsUsed()] (and I guess rows) do not work as expected
- DataTable fields with spaces/whitespace in name cause broken Excel spreadsheet (totals row) (#NAME error)
- Loading a very wide spreadsheet with a large number of rows hits a performance hotspot
- Background color is not showing in Excel but showing in Google Sheet
- Array formula is not properly shifted on row deletion
- TypeLoadException when loading workbook with SixLabors.Fonts 3.0.0 due to GlyphMetrics breaking change
