CHANGES IN R 3.2.4:

  NEW FEATURES:

    * install.packages() and related functions now give a more
      informative warning when an attempt is made to install a base
      package.

    * summary(x) now prints with less rounding when x contains infinite
      values. (Request of PR#16620.)

    * provideDimnames() gets an optional unique argument.

    * shQuote() gains type = "cmd2" for quoting in cmd.exe in Windows.
      (Response to PR#16636.)

    * The data.frame method of rbind() gains an optional argument
      stringsAsFactors (instead of only depending on
      getOption("stringsAsFactors")).

    * smooth(x, *) now also works for long vectors.

    * tools::texi2dvi() has a workaround for problems with the texi2dvi
      script supplied by texinfo 6.1.

      It extracts more error messages from the LaTeX logs when in
      emulation mode.

  UTILITIES:

    * R CMD check will leave a log file build_vignettes.log from the
      re-building of vignettes in the .Rcheck directory if there is a
      problem, and always if environment variable
      _R_CHECK_ALWAYS_LOG_VIGNETTE_OUTPUT_ is set to a true value.

  DEPRECATED AND DEFUNCT:

    * Use of SUPPORT_OPENMP from header Rconfig.h is deprecated in
      favour of the standard OpenMP define _OPENMP.

      (This has been the recommendation in the manual for a while now.)

    * The make macro AWK which is long unused by R itself but recorded
      in file etc/Makeconf is deprecated and will be removed in R
      3.3.0.

    * The C header file S.h is no longer documented: its use should be
      replaced by R.h.

  BUG FIXES:

    * kmeans(x, centers = <1-row>) now works. (PR#16623)

    * Vectorize() now checks for clashes in argument names.  (PR#16577)

    * file.copy(overwrite = FALSE) would signal a successful copy when
      none had taken place.  (PR#16576)

    * ngettext() now uses the same default domain as gettext().
      (PR#14605)

    * array(.., dimnames = *) now warns about non-list dimnames and,
      from R 3.3.0, will signal the same error for invalid dimnames as
      matrix() has always done.

    * addmargins() now adds dimnames for the extended margins in all
      cases, as always documented.

    * heatmap() evaluated its add.expr argument in the wrong
      environment.  (PR#16583)

    * require() etc now give the correct entry of lib.loc in the
      warning about an old version of a package masking a newer
      required one.

    * The internal deparser did not add parentheses when necessary,
      e.g. before [] or [[]].  (Reported by Lukas Stadler; additional
      fixes included as well).

    * as.data.frame.vector(*, row.names=*) no longer produces
      'corrupted' data frames from row names of incorrect length, but
      rather warns about them.  This will become an error.

    * url connections with method = "libcurl" are destroyed properly.
      (PR#16681)

    * withCallingHandler() now (again) handles warnings even during S4
      generic's argument evaluation.  (PR#16111)

    * deparse(..., control = "quoteExpressions") incorrectly quoted
      empty expressions.  (PR#16686)

    * format()ting datetime objects ("POSIX[cl]?t") could segfault or
      recycle wrongly.  (PR#16685)

    * plot.ts(<matrix>, las = 1) now does use las.

    * saveRDS(*, compress = "gzip") now works as documented.
      (PR#16653)

    * (Windows only) The Rgui front end did not always initialize the
      console properly, and could cause R to crash.  (PR#16998)

    * dummy.coef.lm() now works in more cases, thanks to a proposal by
      Werner Stahel (PR#16665).  In addition, it now works for
      multivariate linear models ("mlm", manova) thanks to a proposal
      by Daniel Wollschlaeger.

    * The as.hclust() method for "dendrogram"s failed often when there
      were ties in the heights.

    * reorder() and midcache.dendrogram() now are non-recursive and
      hence applicable to somewhat deeply nested dendrograms, thanks to
      a proposal by Suharto Anggono in PR#16424.

    * cor.test() now calculates very small p values more accurately
      (affecting the result only in extreme not statistically relevant
      cases).  (PR#16704)

    * smooth(*, do.ends=TRUE) did not always work correctly in R
      versions between 3.0.0 and 3.2.3.

    * pretty(D) for date-time objects D now also works well if range(D)
      is (much) smaller than a second.  In the case of only one unique
      value in D, the pretty range now is more symmetric around that
      value than previously.

      Similarly, pretty(dt) no longer returns a length 5 vector with
      duplicated entries for Date objects dt which span only a few
      days.

    * The figures in help pages such as ?points were accidentally
      damaged, and did not appear in R 3.2.3.  (PR#16708)

    * available.packages() sometimes deleted the wrong file when
      cleaning up temporary files.  (PR#16712)

    * The X11() device sometimes froze on Red Hat Enterprise Linux 6.
      It now waits for MapNotify events instead of Expose events,
      thanks to Siteshwar Vashisht. (PR#16497)

    * [dpqr]nbinom(*, size=Inf, mu=.) now works as limit case, for
      'dpq' as the Poisson.  (PR#16727)
      pnbinom() no longer loops infinitely in border cases.

    * approxfun(*, method="constant") and hence ecdf() which calls the
      former now correctly "predict" NaN values as NaN.

    * summary.data.frame() now displays NAs in Date columns in all
      cases.  (PR#16709)
