lifecycle (development version) Unreleased

lifecycle 0.2.0 2020-03-06

lifecycle 0.1.0 2019-08-01

  • Deprecated functions under the control of the developer now warn repeatedly in unit tests.

  • Deprecation warnings now record a backtrace. Call lifecycle::last_warnings() and lifecycle::last_warning() to print the warnings that occurred during the last command, along with their backtraces.

  • The naming scheme of signaller functions has been simplified:

  • The signaller functions now take a version and two descriptors for the deprecated feature and its replacement (the latter is optional). The deprecation message is built from these components. You can pass a details argument to append additional information to the generated deprecation message.

  • Helpers from rlang’s compat-lifecycle.R drop-in file are now exported in this package.
