CHANGES IN R 4.2.1:

  NEW FEATURES:

    * New function utils::findCRANmirror() to find out if a CRAN mirror
      has been selected, otherwise fallback to the main site.  This
      behaves in the same way as tools::CRAN_package_db() and is
      intended for packages wishing to access CRAN for purposes other
      than installing packages.

      The need for this was shown by a day when the main CRAN website
      was offline and a dozen or so packages which had its URL
      hardcoded failed their checks.

  INSTALLATION on a UNIX-ALIKE:

    * The libraries searched for by --with-blas (without a value) now
      include BLIS (after OpenBLAS but before ATLAS).  And on macOS,
      the Accelerate framework (after ATLAS).  (This is patterned after
      the AX_BLAS macro from the Autoconf Archive.)

    * The included LAPACK sources have been updated to 3.10.1.

  UTILITIES:

    * The (full path to) the command tidy to be used for HTML
      validation can be set by environment variable R_TIDYCMD.

    * Setting environment variable _R_CHECK_RD_VALIDATE_RD2HTML_ to a
      false value will override R CMD check --as-cran and turn off HTML
      validation.  This provides a way to circumvent a problematic
      tidy.

      The 2006 version that ships with macOS is always skipped.

  C-LEVEL FACILITIES:

    * The undocumented legacy declarations of Sint, Sfloat, SINT_MAX
      and SINT_MIN in header R.h are deprecated.

  BUG FIXES:

    * fisher.test(d) no longer segfaults for "large" d; fixing PR#18336
      by preventing/detecting an integer overflow reliably.

    * tar(., files=*) now produces correctly the warning about invalid
      uid or gid of files, fixing PR#18344, reported by Martin Morgan.

    * tk_choose.files() with multi = FALSE misbehaved on paths
      containing spaces (PR#18334) (regression introduced in R 4.0.0).

    * sort(x, partial = ind, *) now works correctly notably for the
      non-default na.last = FALSE or TRUE, fixing PR#18335 reported by
      James Edwards.

    * Environment variable _R_CHECK_XREFS_REPOSITORIES_ is only used
      for checking .Rd cross-references in R CMD check (as documented)
      and not for other uses looking for a CRAN mirror.

    * The search for a CRAN mirror when checking packages now uses
      getOption("repos") if that specifies a CRAN mirror, even when it
      does not also specify all three Bioconductor repositories (as was
      previously required).

    * The HTML code generated by tools::Rd2HTML() has been improved to
      pass tidy 5.8.0.

  BUG FIXES on Windows:

    * Writing to a clipboard connection works again, fixing a
      regression in R 4.2.0 (PR#18332).  Re-using a closed clipboard
      connection longer issues a spurious warning about an ignored
      encoding argument.

    * C function getlocale no longer attempts to query an unsupported
      category from the OS, even when requested at R level, which may
      cause crashes when R 4.2.0 (which uses UCRT) is embedded
      (reported by Kevin Ushey).

    * Accent keys now work in GraphApp Unicode windows, which are used
      by Rgui whenever running in a multibyte locale (so also in UTF-8,
      hence fixing a regression in R 4.2.0 for users of systems where R
      4.1 used a single-byte locale).

    * Completion in Rgui now works also with non-ASCII characters.

    * Rgui no longer truncates usage information with --help.

    * Text injection from external applications via SendInput now works
      in GraphApp Unicode windows, fixing a regression in R 4.2.0 for
      Rgui users of systems where R 4.1 used a single-byte locale but R
      4.2.0 uses UTF-8.

    * Performance of txtProgressBar() in Rgui when running in a
      multi-byte locale has been improved (fixing a performance
      regression in R 4.2.0 for users of systems where R 4.1 used a
      single-byte locale).

    * The script editor in Rgui now works also on systems using UTF-8
      as the native encoding.  Users of the script editor have to
      convert their scripts with non-ASCII characters to UTF-8 before
      reading them in R 4.2.1 or newer (on recent Windows where UTF-8
      is used).  This fixes a regression in R 4.2.0, which prevented
      some operations with scripts when they contained non-ASCII
      characters.
