xlsx v2.0.0 Release NotesRelease Date: 2019-11-02 // almost 2 years ago
🚀 This release breaks an important, but bad, assumption that there should be a 1-to-1 mapping between the cells in a sheet and the column definitions. This model simplified the development of the original library a little, but it defeats the purpose of the
coldefinitions (to apply stylistic information over ranges of columns).
🛠 Numerous other fixes have been included. For a full list of changes look here: https://github.com/tealeg/xlsx/milestone/5?closed=1
