Build 5.0.0.51 of xlsgen fixes a problem related to writing header-footer pictures. Copying header-footer pictures across sheets did not work. It now works in XLS, XLSX and XLSB files.

Build 5.0.0.50 of xlsgen fixes a problem related to handling large pivot tables. It improves how column fields are written to XLS/XLSX/XLSB files and by doing so avoids an unnecessary large memory consumption when the resulting file is opened in Excel. By doing so, in a 32-bit scenario it may avoid a 2 GB process limit crash.

Build 5.0.0.49 of xlsgen improves HTML import, that is, how data formatted as HTML gets imported in xlsgen in order to create an Excel file.

HTML import now supports two mechanisms for splitting a row of data into multiple columns :

- a SeparationCharacters property in the IXlsHTMLImportOptions interface which allows to specity a string used as separation.

- a SplitBySeparatorString property in the IXlsImportColumnSplitter interface, which adds a string rather than single character property if you were already using the column split interface.
