This is the relevant part of the NEWS file



    * Some recently-added Windows time zone names have been added to
      the conversion table used to convert these to Olson names.
      (Including those relating to changes for Russia in Oct 2014, as
      in PR#16503.)

    * (Windows) Compatibility information has been added to the
      manifests for Rgui.exe, Rterm.exe and Rscript.exe.  This should
      allow win.version() and Sys.info() to report the actual Windows
      version up to Windows 10.

    * Windows "wininet" FTP first tries EPSV / PASV mode rather than
      only using active mode (reported by Dan Tenenbaum).

    * which.min(x) and which.max(x) may be much faster for logical and
      integer x and now also work for long vectors.

    * The 'emulation' part of tools::texi2dvi() has been somewhat
      enhanced, including supporting quiet = TRUE.  It can be selected
      by texi2dvi = "emulation".

      (Windows) MiKTeX removed its texi2dvi.exe command in Sept 2015:
      tools::texi2dvi() tries texify.exe if it is not found.

    * (Windows only) Shortcuts for printing and saving have been added
      to menus in Rgui.exe.  (Request of PR#16572.)

    * loess(..., iterTrace=TRUE) now provides diagnostics for
      robustness iterations, and the print() method for
      summary(<loess>) shows slightly more.

    * The included version of PCRE has been updated to 8.38, a bug-fix

    * View() now displays nested data frames in a more friendly way.
      (Request with patch in PR#15915.)


    * The included configuration code for libintl has been updated to
      that from gettext version - this should only affect how
      an external library is detected (and the only known instance is
      under OpenBSD).  (Wish of PR#16464.)

    * configure has a new argument --disable-java to disable the checks
      for Java.

    * The configure default for MAIN_LDFLAGS has been changed for the
      FreeBSD, NetBSD and Hurd OSes to one more likely to work with
      compilers other than gcc (FreeBSD 10 defaults to clang).

    * configure now supports the OpenMP flags -fopenmp=libomp (clang)
      and -qopenmp (Intel C).

    * Various macros can be set to override the default behaviour of
      configure when detecting OpenMP: see file config.site.

    * Source installation on Windows has been modified to allow for
      MiKTeX installations without texi2dvi.exe.  See file


    * regexpr(pat, x, perl = TRUE) with Python-style named capture did
      not work correctly when x contained NA strings.  (PR#16484)

    * The description of dataset ToothGrowth has been
      improved/corrected.  (PR#15953)

    * model.tables(type = "means") and hence TukeyHSD() now support
      "aov" fits without an intercept term.  (PR#16437)

    * close() now reports the status of a pipe() connection opened with
      an explicit open argument.  (PR#16481)

    * Coercing a list without names to a data frame is faster if the
      elements are very long. (PR#16467)

    * (Unix-only) Under some rare circumstances piping the output from
      Rscript or R -f could result in attempting to close the input
      file twice, possibly crashing the process.  (PR#16500)

    * (Windows) Sys.info() was out of step with win.version() and did
      not report Windows 8.

    * topenv(baseenv()) returns baseenv() again as in R 3.1.0 and
      earlier.  This also fixes compilerJIT(3) when used in .Rprofile.

    * detach()ing the methods package keeps .isMethodsDispatchOn()
      true, as long as the methods namespace is not unloaded.

    * Removed some spurious warnings from configure about the
      preprocessor not finding header files.  (PR#15989)

    * rchisq(*, df=0, ncp=0) now returns 0 instead of NaN, and
      dchisq(*, df=0, ncp=*) also no longer returns NaN in limit cases
      (where the limit is unique).  (PR#16521)

    * pchisq(*, df=0, ncp > 0, log.p=TRUE) no longer underflows (for
      ncp > ~60).

    * nchar(x, "w") returned -1 for characters it did not know about
      (e.g. zero-width spaces): it now assumes 1.  It now knows about
      most zero-width characters and a few more double-width

    * Help for which.min() is now more precise about behavior with
      logical arguments.  (PR#16532)

    * The print width of character strings marked as "latin1" or
      "bytes" was in some cases computed incorrectly.

    * abbreviate() did not give names to the return value if minlength
      was zero, unlike when it was positive.

    * (Windows only) dir.create() did not always warn when it failed to
      create a directory.  (PR#16537)

    * When operating in a non-UTF-8 multibyte locale (e.g. an East
      Asian locale on Windows), grep() and related functions did not
      handle UTF-8 strings properly.  (PR#16264)

    * read.dcf() sometimes misread lines longer than 8191 characters.
      (Reported by Herv'e Pag`es with a patch.)

    * within(df, ..) no longer drops columns whose name start with a

    * The built-in HTTP server converted entire Content-Type to
      lowercase including parameters which can cause issues for
      multi-part form boundaries (PR#16541).

    * Modifying slots of S4 objects could fail when the methods package
      was not attached. (PR#16545)

    * splineDesign(*, outer.ok=TRUE) (splines) is better now
      (PR#16549), and interpSpline() now allows sparse=TRUE for speedup
      with non-small sizes.

    * If the expression in the traceback was too long, traceback() did
      not report the source line number.  (Patch by Kirill M"uller.)

    * The browser did not truncate the display of the function when
      exiting with options("deparse.max.lines") set.  (PR#16581)

    * When bs(*, Boundary.knots=) had boundary knots inside the data
      range, extrapolation was somewhat off.  (Patch by Trevor Hastie.)

    * var() and hence sd() warn about factor arguments which are
      deprecated now. (PR#16564)

    * loess(*, weights = *) stored wrong weights and hence gave
      slightly wrong predictions for newdata.  (PR#16587)

    * aperm(a, *) now preserves names(dim(a)).

    * poly(x, ..) now works when either raw=TRUE or coef is specified.

    * data(package=*) is more careful in determining the path.

    * prettyNum(*, decimal.mark, big.mark): fixed bug introduced when
      fixing PR#16411.
