rlang 1.0.1

• New rlang_call_format_srcrefs global option (#1349). Similar to
  rlang_trace_format_srcrefs, this option allows turning off the
  display of srcrefs in error calls. This can be useful for
  reproducibility but note that srcrefs are already disabled
  within testthat by default.

• abort(parent = NA) is now supported to indicate an unchained
  rethrow. This helps abort() detect the condition handling context
  to create simpler backtraces where this context is hidden by
  default.

• When parent is supplied, abort() now loops over callers to
  detect the condition handler frame. This makes it easier to wrap or
  extract condition handlers in functions without supplying .frame.

• When parent is supplied and call points to the condition setup
  frame (e.g. withCallingHandlers() or try_fetch()), call is
  replaced with the caller of that setup frame. This provides a more
  helpful default call.

• is_call() is now implemented in C for performance.

• Fixed performance regression in trace_back().

• Fixed a partial matching issue with header, body, and footer
  condition fields.

• eval_tidy() calls are no longer mentioned in error messages.
