This option is enabled by setting the global option `tutorial.quick_restore = 2` or the environment variable `TUTORIAL_QUICK_RESTORE=2`. This option augments the quick restore value when `TRUE` or `1`, wherein only the last submitted **code** is restored, such that users will need to click the "Submit" button to evaluate and see the output. (#794) +- A new `exercise.pipe` tutorial or exercise chunk option can now be used to determine which pipe operator is used for interactive exercises. The default is `"|>"` (the native R pipe) when the tutorial is rendered with R >= 4.1.0, or `"%>%"` otherwise (the magrittr pipe). You can set the pipe used for the tutorial using `tutorial_options()`, or you can use `exercise.pipe` as a knitr chunk option on an individual exercise chunk.
