This is the relevant part of the NEWS file



    * The C-level API version of R's integrate(), Rdqags() in Applic.h,
      now returns the correct number of integrand evaluations neval,
      fixing PR#18515 reported and diagnosed by Stephen Wade.

    * The C prototypes for LAPACK calls dspgv and dtptrs in
      R_exts/Lapack.h had one too many and one too few character length
      arguments - but this has not caused any known issues. To get the
      corrected prototypes, include

              #include <Rconfig.h> // for PR18534fixed
              #ifdef PR18534fixed
              # define usePR18534fix 1
              #include <R_exts/Lapack.h>
      in your C/C++ code (PR#18534).


    * Many of the checks of esoteric Internet operations and those
      using unreliable external sites have been moved to a new target
      that is not run by default and primarily intended for the core
      developers.  To run them use

              cd tests; make test-Internet-dev

    * .S3methods(), typically called from methods(), again marks
      methods from package base as visible.

      Also, the visibility of non-base methods is again determined by
      the method's presence in search().

    * tools::Rdiff() is now more robust against invalid strings, fixing
      installation tests on Windows without Rtools installed

    * Fix (new) bug in hcl.colors(2, *), by Achim Zeileis (PR#18523).

    * head(., <illegal>) and tail(..) now produce more useful "Error in
      ...." error messages, fixing PR#18362.

    * Package code syntax on Windows is checked in UTF-8 when UTF-8 is
      the native encoding.

    * na.contiguous(x) now also returns the first run, when it is at
      the beginning and there is a later one of the same length;
      reported to R-devel, including a fix, by Georgi Boshnakov.
      Further, by default, it modifies only an existing attr(*,"tsp")
      but otherwise no longer sets one.

    * chol(<not pos.def>, pivot = <T|F>) now gives a correct error or
      warning message (depending on pivot), thanks to Mikael Jagan's
