knitr 1.28

BUG FIXES

• hook_pdfcrop() no longer crops images included via include_graphics() now (thanks, @hpages #1797, @salim-b #1800).

MAJOR CHANGES

• If the hook_pdfcrop() is enabled, the non-PDF image will be cropped only if the magick package is available, otherwise it will signal a message. In the previous version, it will signal an error (thanks, @trannhatanh89, #1796).

• By default, include_graphics(files) will signal an error if any files do not exist and are not web resources. To avoid the error (e.g., if you think it is a false positive), use include_graphics(..., error = FALSE) (thanks, @hadley, #1717).
