- CHANGES IN R 4.1.0:
  FUTURE DIRECTIONS:
    * It is planned that the 4.1.x series will be the last to support
      32-bit Windows, with production of binary packages for that
      series continuing until early 2023.
  SIGNIFICANT USER-VISIBLE CHANGES:
    * Data set esoph in package datasets now provides the correct
      numbers of controls; previously it had the numbers of cases added
      to these.  (Reported by Alexander Fowler in PR#17964.)
  NEW FEATURES:
    * www.omegahat.net is no longer one of the repositories known by
      default to setRepositories().  (Nowadays it only provides source
      packages and is often unavailable.)
    * Function package_dependencies() (in package tools) can now use
      different dependency types for direct and recursive dependencies.
    * The checking of the size of tarball in R CMD check --as-cran
      <pkg> may be tweaked via the new environment variable
      _R_CHECK_CRAN_INCOMING_TARBALL_THRESHOLD_, as suggested in
      PR#17777 by Jan Gorecki.
    * Using c() to combine a factor with other factors now gives a
      factor, an ordered factor when combining ordered factors with
      identical levels.
    * apply() gains a simplify argument to allow disabling of
      simplification of results.
    * The format() method for class "ftable" gets a new option justify.
      (Suggested by Thomas Soeiro.)
    * New ...names() utility.  (Proposed by Neal Fultz in PR#17705.)
    * type.convert() now warns when its as.is argument is not
      specified, as the help file always said it _should_.  In that
      case, the default is changed to TRUE in line with its change in
