Build 3.0.0.143 of xlsgen fixes how chart position is written back to XLSX files. The algorithm has been fluctuating due to it being undocumented.

Build 3.0.0.142 of xlsgen improves how legend formatting details and position are read and written back from XLSX files.

Build 3.0.0.141 of xlsgen supports writing individual data label positions in XLSX files.

Build 3.0.0.140 of xlsgen adds support for deletion of individual legend entries in XLSX files.

Build 3.0.0.139 of xlsgen fixes the handling of subcharts when writing XLSX files. In several scenarios, the "stacked" property would be written for all subcharts, instead of the right one(s).

Build 3.0.0.138 of xlsgen adds support for writing series-wide data label number formats in XLSX files.

Build 3.0.0.137 of xlsgen adds support for reading some missing custom data label properties from XLSX files.

Build 3.0.0.134 of xlsgen adds support for non secable spaces to the Html output. Basically non secable spaces is multiples spaces that are intentionally in the content for indenting purposes. So far there was not a special encoding into a &nbsp entity so when viewed in an Html browser, those spaces would collapse as a single space.

Build 3.0.0.133 of xlsgen adds support for center across selection in the Html output. Center across selection is similar to merged cells except it is not merged cells.

Build 3.0.0.132 adds support for international number formats. These are formats where the currency is automatically prefixed or suffixed to the number format at run-time, regardless where it is defined, depending on the user's regional settings (in Windows / Config panel / Regional settings, there are settings for the format of positive numbers and negative numbers, including the currency position, as well as the currency symbol itself).

xlsgen supports all of that transparently for who ever uses 4 of these international number formats.

Build 3.0.0.131 of xlsgen has a fix for built-in number formats. 4 of the built-in number formats had a parenthesis instead of an underscore followed by a parenthesis, leading to a different parsing in xlsgen. (underscore followed by a character is for padding the width of said character).
