bookdown 0.20

NEW FEATURES

• If delete_merged_file is set to false in _bookdown.yml, the merged (Rmd or md) file will not be deleted after the book is rendered (thanks, ilse pit, https://stackoverflow.com/q/61973608/559676).

• Numeric footnotes duplicated across chapters are now automatically renumbered. This is done by passing the --file-scope argument to pandoc (and having it operate on split out individual chapters of the target .md file rather than a combined file). This behavior can be toggled off by setting options(bookdown.render.file_scope = FALSE).

BUG FIXES

• Fixed a JS issue in gitbook when it is used with jQuery 3.x (thanks, @afkegel, #895).

MINOR CHANGES

• Removed the encoding argument from bookdown::render_book(). This argument has always been ignored in bookdown.
