This is the relevant part of the NEWS file



    * The workaround in headers R.h and Rmath.h (using namespace std;)
      for the Oracle Developer Studio compiler is no longer needed now
      C++11 is required so has been removed.  A couple more usages of
      log() (which should have been std::log()) with an int argument
      are reported on Solaris.

    * The undocumented limit of 4095 bytes on messages from the
      S-compatibility macros PROBLEM and MESSAGE is now documented and
      longer messages will be silently truncated rather than
      potentially causing segfaults.

    * If the R_NO_SEGV_HANDLER environment variable is non-empty, the
      signal handler for SEGV/ILL/BUS signals (which offers recovery
      user interface) is not set. This allows more reliable debugging
      of crashes that involve the console.


    * The legacy S-compatibility macros PROBLEM, MESSAGE, ERROR, WARN,
      WARNING, RECOVER, ... are deprecated and will be hidden in R
      4.2.0. R's native interface of Rf_error and Rf_warning has long
      been preferred.


    * .mapply(F, dots, .) no longer segfaults when dots is not a list
      and uses match.fun(F) as always documented; reported by Andrew
      Simmons in PR#18164.

    * hist(<Date>, ...) and hist(<POSIXt>, ...)  no longer pass
      arguments for rect() (such as col and density) to axis().
      (Thanks to Sebastian Meyer's PR#18171.)

    * \Sexpr{ch} now preserves Encoding(ch). (Thanks to report and
      patch by Jeroen Ooms in PR#18152.)

    * Setting the RNG to "Marsaglia-Multicarry" e.g., by RNGkind(), now
      warns in more places, thanks to Andr'e Gillibert's report and
      patch in PR#18168.

    * gray(numeric(), alpha=1/2) no longer segfaults, fixing PR#18183,
      reported by Till Krenz.

    * Fixed dnbinom(x, size=<very_small>, .., log=TRUE) regression,
      reported by Martin Morgan.

    * as.Date.POSIXlt(x) now keeps names(x), thanks to Davis Vaughan's
      report and patch in PR#18188.

    * model.response() now strips an "AsIs" class typically, thanks to
      Duncan Murdoch's report and other discussants in PR#18190.

    * try() is considerably faster in case of an error and long call,
      as e.g., from some do.call().  Thanks to Alexander Kaever's
      suggestion posted to R-devel.

    * qqline(y = <object>) such as y=I(.), now works, see also

    * Non-integer mgp par() settings are now handled correctly in
      axis() and mtext(), thanks to Mikael Jagan and Duncan Murdoch's
      report and suggestion in PR#18194.

    * formatC(x) returns length zero character() now, rather than ""
      when x is of length zero, as documented, thanks to Davis
      Vaughan's post to R-devel.

    * removeSource(fn) now retains (other) attributes(fn).
