Footnotes with linebreaks

 ## [Unreleased]
 
+- **Breaking** Footnotes are by default separated with linebreaks now. This can be changed by setting the new `Table` option `linebreak_footnotes = false` [#34](https://github.com/PumasAI/SummaryTables.jl/pull/34).
 - **Breaking** Changed `show_overall` keyword of `table_one` to `show_total`. The name of all total columns was changed from `"Overall"` to `"Total"` as well but this can be changed using the new `total_name` keyword.
 - Added ability to show "Total" statistics for subgroups in `table_one` [#30](https://github.com/PumasAI/SummaryTables.jl/pull/30).
 - Fixed tagging of header rows in docx output, such that the header section is now repeated across pages as expected [#32](https://github.com/PumasAI/SummaryTables.jl/pull/32).
