This is the relevant part of the NEWS file



    * require(pkg, quietly = TRUE) is quieter and in particular does
      not warn if the package is not found.


    * Use of ftp:// URIs should be regarded as deprecated, with
      on-going support confined to method = "libcurl" and not routinely
      tested.  (Nowadays no major browser supports them.)

    * The non-default method = "internal" is deprecated for http:// and
      ftp:// URIs for both download.file and url.

    * On Windows, method = "wininet" is deprecated for http://,
      https:// and ftp:// URIs for both download.file and url.  (A
      warning is only given for ftp://.)

      For ftp:// URIs the default method is now "libcurl" if available
      (which it is on CRAN builds).

      method = "wininet" remains the default for http:// and https://
      URIs but if libcurl is available, using method = "libcurl" is


    * make check now works also without a LaTeX installation.  (Thanks
      to Sebastian Meyer's PR#18103.)


    * make check-devel works again in an R build configured with

    * qnbinom(p, size, mu) for large size/mu is correct now in a range
      of cases (PR#18095); similarly for the (size, prob)
      parametrization of the negative binomial.  Also qpois() and
      qbinom() are better and or faster for extreme cases.  The
      underlying C code has been modularized and is common to all four
      cases of discrete distributions.

    * gap.axis is now part of the axis() arguments which are passed
      from bxp(), and hence boxplot().  (Thanks to Martin Smith's
      report and suggestions in PR#18109.)

    * .First and .Last can again be set from the site profile.

    * seq.int(from, to, *) and seq.default(..) now work better in large
      range cases where from-to is infinite where the two boundaries
      are finite.

    * all.equal(x,y) now returns TRUE correctly also when several
      entries of abs(x) and abs(y) are close to .Machine$double.xmax,
      the largest finite numeric.

    * model.frame() now clears the object bit when removing the class
      attribute of a value via na.action (PR#18100).

    * charClass() now works with multi-character strings on Windows
      (PR#18104, fixed by Bill Dunlap).

    * encodeString() on Solaris now works again in Latin-1 encoding on
      characters represented differently in UTF-8.  Support for
      surrogate pairs on Solaris has been improved.

    * file.show() on Windows now works with non-ASCII path names
      representable in the current native encoding (PR#18132).

    * Embedded R on Windows can now find R home directory via the
      registry even when installed only for the current user

    * pretty(x) with finite x now returns finite values also in the
      case where the extreme x values are close in size to the maximal
      representable number .Machine$double.xmax.

      Also, it's been tweaked for very small ranges and when a boundary
      is close (or equal) to zero; e.g., pretty(c(0,1e-317)) no longer
      has negative numbers, currently still warning about a very small
      range, and pretty(2^-(1024 - 2^-1/(c(24,10)))) is more accurate.

    * The error message for not finding vignette files when weaving has
      correct file sizes now. (Thanks to Sebastian Meyer's PR#18154.)

    * dnbinom(20, <large>, 1) now correctly gives 0, and similar cases
      are more accurate with underflow precaution.  (Reported by
      Francisco Vera Alcivar in PR#18072.)
