v3.0.0
Summary
Version 3.0.0 of the xlsx library fixes a significant number of issues, but breaks backwards compatibility in order to do so. For a full list of changes see the milestone.
DiskV backend
You can now optionally pass the UseDiskVCellStore operation to all methods that open, or create an xlsx.File. Selecting this option will result in much lower memory usage when handling large sheets, but will run slightly slower than the default in-memory cell store backend.
Streaming support removed
If you were previously using the StreamFileBuilder you should use V2 of this library of earlier.
Sheet.ForEachRow and Row.ForEachCell accept options.
You can indicate that you'd like to SkipEmptyRows or SkipEmptyCells.
