  • New vignettes:

    • vignette("stages") describes the lifecycle stages
    • vignette("manage") teaches you how to manage lifecycle changes in
      functions you use.
    • vignette("communicate") shows how to use lifecycle in functions that
      you write.
  • In deprecate_soft(), deprecate_warn(), and deprecate_stop():

    • You can deprecate an argument with foo(arg) instead of foo(arg =) (#78).
      This syntax is similar in spirit to the formal arguments of function

    • You can deprecate R6 methods by using class$method() (#54).

    • A character vector details is now converted into a bulleted list (#55).

    • Messages for non-prefix functions (like "x<-()" and "%>%()")
      look a little nicer (#95).

    • Manually printed warnings now omit the advice footer (#68).

  • Experimental signal_stage() can be used to signal that a function is
    experimental or superseded. These signals are not currently hooked up to any
    behaviour, but we'll add tools in a future release (#44).

  • lifecycle_cnd_data() has been removed; as far as I can tell it wasn't
    used by anyone.
