 R News
 
+CHANGES IN R-devel:
+
+  SIGNIFICANT USER-VISIBLE CHANGES:
+
+    * Startup banners, R --version, sessionInfo() and R CMD check no
+      longer report (64-bit) as part of the platform as this is almost
+      universal - the increasingly rare 32-bit platforms will still
+      report (32-bit).
+
+      On Windows, ditto for window titles.
+
+    * is.atomic(NULL) now returns FALSE, as NULL is not an atomic
+      vector.  Strict back-compatibility would replace is.atomic(foo)
+      by (is.null(foo) || is.atomic(foo)) but should happen only
+      sparingly.
+
+  NEW FEATURES:
+
+    * The confint() methods for "glm" and "nls" objects have been
+      copied to the stats package.  Previously, they were stubs which
+      called versions in package MASS. The MASS namespace is no longer
+      loaded if you invoke (say) confint(glmfit).  Further, the "glm"
+      method for profile() and the plot() and pairs() methods for class
+      "profile" have been copied from MASS to stats.  (profile.nls()
+      and plot.profile.nls() were already in stats.)
+
+    * The confint() and profile methods for "glm" objects have gained a
+      possibility to do profiling based on the Rao Score statistic in
+      addition to the default Likelihood Ratio. This is controlled by a
+      new test = argument.
+
+    * The "glm" method for anova() computes test statistics and
+      p-values by default, using a chi-squared test or an F test
+      depending on whether the dispersion is fixed or free.  Test
+      statistics can be suppressed by giving argument test a false
+      logical value.
+
+    * In setRepositories() the repositories can be set using their
+      names via name = instead of index ind =.
+
+    * methods() and .S3methods() gain a all.names option for the (rare)
+      case where functions starting with a . should be included.
+
+    * Serializations can now be interrupted (e.g., by Ctrl-C on a
+      Unix-alike) if they take too long, e.g., from save.image(),
+      thanks to suggestions by Ivan Krylov and others on R-devel.
+
+    * New startup option --max-connections to set the maximum number of
+      connections for the session.  Defaults to 128 as before: allowed
+      values up to 4096 (but resource limits may in practice restrict
+      to smaller values).
+
+    * R on Windows (since Windows 10 2004) now uses the new Segment
+      Heap allocator. This may improve performance of some
+      memory-intensive applications.
+
+    * When R packages are built, typically by R CMD build <pkg>, the
+      new --user=<build_user> option overrides the (internally
+      determined) user name, currently Sys.info()["user"] or LOGNAME.
+      This is a (modified) fulfillment of Will Landau's suggestion in
+      PR#17530.
+
+    * tools::testInstalledBasic() gets new optional arguments outDir
+      and testSrcdir, e.g., allowing to use it in a builddir != srcdir
+      setup, and in standard "binary" Windows installation *if* a
+      source tests/ folder is present.
+
+    * range(<DT_with_Inf>, finite = TRUE) now work for objects of class
+      "Date", "POSIXct", and "POSIXlt" with infinite entries,
+      analogously to range.default(), as proposed by Davis Vaughan on
+      R-devel.  Other range()-methods can make use of new .rangeNum().
+
+    * New .internalGenerics complementing .S3PrimitiveGenerics, for
+      documentation and low-level book keeping.
+
+    * grid() now invisibly returns the x- and y- coordinates at which
+      the grid-lines were drawn.
+
+    * norm(., type) now also works for complex matrices.
+
+    * kappa(., exact = TRUE, norm = *) now works for all norms and also
+      for complex matrices.  In symmetric / triangular cases, new
+      argument uplo = "U" | "L" allows to specify the upper or lower
+      triangular part.
+
+    * memDecompress(type = "unknown") recognizes compression in the
+      default 'zlib' format as used by memCompress(type = "gzip").
+
+    * memCompress() and memDecompress() will use the libdeflate library
+      (<https://github.com/ebiggers/libdeflate>) if installed.  This
+      uses the same type of compression for type = "gzip" but is 1.5-2x
+      faster than the system libz library on some common platforms: the
+      speed-up may depend on the library version.
+
+    * diff() for objects of class "Date", "POSIXct", and "POSIXlt"
+      accepts a units argument passed via ....
+
+    * Dynamic help now does a much better job rendering package
+      DESCRIPTION metadata.
+
+    * Rprof() gains an event argument and support for elapsed (real)
+      time profiling on Unix (PR#18076).
+
+    * filled.contour() gains key.border argument.
+
+    * tools::update_pkg_po() gets pot_make and mo_make options for
+      _not_ re-making the corresponding files, and additionally option
+      verbose.
+
+    * Hexadecimal string colour specifications are now accepted in
+      short form, so, for example, we can use "#123", which is
+      equivalent to "#112233".
+
+      Thanks to MikeFC for the original idea and Ella Kaye, Malcolm
+      Barrett, George Stagg, and Hanne Oberman for the patch.
+
+    * Plain-text help shows \var markup with angle brackets.
+
+    * The new experimental primitive function declare() is intended to
+      eventually allow information about R code to be communicated to
+      the interpreter, compiler, and code analysis tools. The syntax
+      for declarations is still being developed.
+
+    * Functions psmirnov(), qsmirnov() and rsmirnov() in package stats
+      have argument two.sided changed to alternative, to take into
+      account that the permutation distributions of the one-sided
+      statistics can be different in the case of ties.  Consequence of
+      PR#18582.
+
+    * sort() is now an implicit S4 generic in methods.
+
+    * Formatting and printing, format(z), print(z), of complex vectors
+      z no longer zap relatively small real or imaginary parts to zero,
+      fixing PR#16752.  This is an API change, as it was documented
+      previously to round real and imaginary parts together on purpose,
+      producing nicer looking output.  As mentioned, e.g. in the PR,
+      this change is compatible to many other "R-like" programming
+      environments.
+
+      We have simplified the internal code and now basically format the
+      real and imaginary parts independently of each other.
+
+    * New experimental functions Tailcall and Exec to support writing
+      stack-space-efficient recursive functions.
+
+    * Where characters are attempted to be plotted by pdf(),
+      postscript() and xfig() which are not in the selected 8-bit
+      character set (most often Latin-1) and the R session is using a
+      UTF-8 locale, the warning messages will show the UTF-8 character
+      rather than its bytes and one dot will be substituted per
+      character rather than per byte.  (Platforms whose iconv() does
+      transliteration silently plot the transliteration.)
+
+      In a UTF-8 locale some transliterations are now done with a
+      warning (e.g., dashes and Unicode minus to hyphen, ligatures are
+      expanded, permille (?) is replaced by o/oo), although the OS may
+      have got there first.  These are warnings as they will continue
+      to be replaced by dots in earlier versions of R.
+
+    * The matrix multiplication functions crossprod() and tcrossprod()
+      are now also primitive and S3 generic, as %*% had become in R
+      4.3.0.
+
+    * source() and example() have a new optional argument catch.aborts
+      which allows continued evaluation of the R code after an error.
+
+    * The non-Quartz tiff() devices allow additional types of
+      compression if supported by the platform's libtiff library.
+
+    * The list of base and recommended package names is now provided by
+      tools :: standard_package_names.
+
+    * cairo_pdf() and cairo_ps() default to onefile = TRUE to closer
+      match pdf() and postscript().
+
+    * New option catch.script.errors provides a documented way to catch
+      errors and continue in non-interactive use.
+
+    * L %||% R newly in base is an expressive idiom for the
+      if(!is.null(L)) L else R or if(is.null(L)) R else L phrases.
+
+    * warnings() now always inherits from "warnings" as documented,
+      newly also in the case of no warnings, where it previously
+      returned NULL.
+
+    * as.complex("1i") now returns 1i instead of NA with a warning.
+
+    * z <- c(NA, 1i) now keeps the imaginary part Im(z[1]) == 0, no
+      longer coercing to NA_complex_.  Similarly, cumsum(z) correctly
+      sums real and imaginary parts separately, i.e., without
+      "crosstalk" in case of NAs.
+
+    * On Alpine Linux iconv() now maps "latin2", "latin-2", "latin9"
+      and "latin-9" to names the OS knows about (case-insensitively).
+
+    * iconv(sub = "Unicode") now zero-pads to four (hex) digits, rather
+      than to 4 or 8.  (This seems to have become the convention once
+      Unicode restricted the number of Unicode points to 2^31 - 1 and
+      so will never need more than 6 digits.)
+
+    * NCOL(NULL) now returns 0 instead of 1, for consistency with
+      cbind().
+
+    * Support for encoding = "MacRoman" has been removed from the pdf()
+      and postscript() devices - this was a legacy encoding supporting
+      classic macOS up to 2001 (with various revisions), and no longer
+      has universal libiconv support.
+
+  INSTALLATION on a UNIX-ALIKE:
+
+    * System valgrind headers are required to use configure option
+      --with-valgrind-instrumentation with value 1 or 2.
+
+    * configure will warn if it encounters a 32-bit build, as that is
+      nowadays almost untested.
+
+    * Environment variable R_SYSTEM_ABI is no longer used and so no
+      longer recorded in etc/Renviron (it was not on Windows and was
+      only ever used when preparing package tools).
+
+    * If the libdeflate library and headers are available, libdeflate
+      rather than libz is used to (de)compress R objects in lazy-load
+      databases, Typically tasks spend up to 5% of their time on such
+      operations, although creating lazy-data databases is one of the
+      exceptions.
+
+      This can be suppressed if the library is available by the
+      configure option --without-libdeflate-compression.
+
+    * configure option --enable-lto=check has not worked reliably since
+      2019 and has been removed.
+
+  INSTALLATION on macOS:
+
+    * A new configure option --with-newAccelerate makes use of Apple's
+      'new' BLAS / LAPACK interfaces in their Accelerate framework.
+      Those interfaces are only available in macOS 13.3 or later, and
+      building requires SDK 13.3 or later (from the Command Line Tools
+      or Xcode 14.3 or later).
+
+      By default the option uses new Accelerate for BLAS calls: to also
+      use it for LAPACK use --with-newAccelerate=lapack.  The later
+      interfaces provide LAPACK 3.9.1 rather than 3.2.1: 3.9.1 is from
+      2021-04 and does not include the improved algorithms introduced
+      in LAPACK 3.10.0 (including for BLAS calls).
+
+  UTILITIES:
+
+    * R CMD check notes when S4-style exports are used without
+      declaring a strong dependence on package methods.
+
+    * tools::checkRd() (used by R CMD check) detects more problems with
+      \Sexpr-based dynamic content, including bad nesting of \Sexprs
+      and invalid arguments.
+
+    * tools::checkRd() now reports Rd titles and section names ending
+      in a period; this is ignored by R CMD check unless environment
+      variable _R_CHECK_RD_CHECKRD_MINLEVEL_ is set to -5 or smaller.
+
+    * R CMD check now notes Rd files without an \alias, as long
+      documented in 'Writing R Extensions' ?1.3.1.  The check for a
+      missing \description has been moved from tools::checkRd() to
+      tools::checkRdContents().
+
+    * R CMD check now visits inst/NEWS.Rd when checking Rd files.
+
+    * tools::checkDocFiles() and tools::checkRdContents() now also
+      check internal Rd files by default, but "specially" (ignoring
+      missing documentation of arguments).
+
+    * R CMD Rdiff gets option --useEx.
+
+    * R CMD check now warns on non-portable uses of Fortran KIND such
+      as INTEGER(KIND=4) and REAL(KIND=8).
+
+      To see the failing lines set environment variable
+      _R_CHECK_FORTRAN_KIND_DETAILS_ to a true value.
+
+    * When checking Rd files, R CMD check --as-cran now notes some of
+      the "lost braces" that tools::checkRd() finds.  Typical problems
+      are Rd macros missing the initial backslash (e.g., code{...}),
+      in-text set notation (e.g., {1, 2}, where the braces need
+      escaping), and \itemize lists with _description_-like entries of
+      the form \item{label}{description}.
+
+  C-LEVEL FACILITIES:
+
+    * Headers R_ext/Applic.h and R-ext/Linpack.h used to include
+      R_ext/BLAS.h although this was undocumented and unneeded by their
+      documented entry points.  They no longer do so.
+
+    * New R_missing(), factored out from do_missing(), used to fix
+      PR#18579.
+
+    * SEXP type S4SXP has been renamed OBJSXP to support experimenting
+      with alternative object systems.  The S4SXP value can still be
+      used in C code but is now deprecated. Based on contributions from
+      the R Consortium Object-Oriented Programming Working Group.
+
+  DEPRECATED AND DEFUNCT:
+
+    * data() no longer handles zipped data from long-defunct (since R
+      2.13.0) --use-zip-data installations.
+
+    * The legacy graphics devices pictex() and xfig() are now
+      deprecated.  They do not support recent graphics enhancements and
+      their font-handling is rudimentary. The intention is to retain
+      them for historical interest as long as they remain somewhat
+      functional.
+
+  BUG FIXES:
+
+    * The methods package is more robust to not being attached to the
+      search path. More work needs to be done.
+
+    * pairwise.t.test() misbehaved when subgroups had 0 DF for
+      variance, even with pool.sd=TRUE PR#18594 (Jack Berry).
+
+    * Probability distribution functions [dpq]<distrib>(x, *), but also
+      bessel[IKJY](x, .) are now consistently preserving attributes(x)
+      when length(x) == 0, e.g., for a 2 x 0 matrix, thanks to Karolis
+      Koncevi?ius' report PR#18509.
+
+    * Group "Summary" computations such as sum(1:3, 4, na.rm = 5, NA,
+      7, na.rm = LL) now give an error instead of either 17 or NN for
+      LL true or false, as proposed by Ivan Krylov on the R-devel
+      mailing list.  (This also means it is now an error to specify
+      na.rm more than once.)
+
+    * as.complex(x) now returns complex(real=x, imaginary=0) for _all_
+      numerical and logical x, notably also for NA or NA_integer_.
+
+    * Directories are now omitted by file.copy(,recursive = FALSE) and
+      in file.append() (PR#17337).
+
+    * gsub() and sub() are now more robust to integer overflow when
+      reporting errors caused by too large input strings (PR#18346).
+
+    * Top-level handlers are now more robust to attempts to remove a
+      handler whilst handlers are running (PR#18508).
+
+    * The handling of Alt+F4 in dialogs created on Windows using
+      GraphApp has been fixed (PR#13870).
+
+    * density() more consistently computes grid values for the
+      FFT-based convolution, following Robert Schlicht's analysis and
+      proposal in PR#18337, correcting density values typically by a
+      factor of about 0.999.  Optional old.coords=TRUE provides back
+      compatibility.
+
+    * palette.colors() gains a name argument that defaults to FALSE
+      controlling whether the vector of colours that is returned has
+      names (where possible).  PR#18529.
+
+    * tools::xgettext() no longer extracts the (non-translatable) class
+      names from warningCondition and errorCondition calls.
+
+    * S3method(<gen>, <class>, <func>) in the NAMESPACE file now works
+      (again) when <func> is visible from the namespace, e.g.,
+      imported, or in base.
+
+    * getParseData(f) now also works for a function defined in the
+      first of several <pkg>/R/*.R source files, thanks to Kirill
+      M?ller's report and Duncan Murdoch's patch in PR#16756.
+
+    * Rd \Sexpr macros with nested #ifdef conditionals were not
+      processed.
+
+    * A non-blocking connection with non-default encoding such as a
+      socket, now correctly returns from readLines() after new data has
+      arrived also when its EOF had been reached previously.  Thanks to
+      Peter Meilstrup's report on R-devel and Ivan Krylov's report and
+      patch proposal in PR#18555.
+
+    * tools::checkRdContents() failed to detect empty argument
+      descriptions when they spanned multiple lines, including those
+      generated by prompt().  These cases are now noted by R CMD check.
+
+    * Plain-text help no longer outputs spurious colons in the
+      arguments list (for multi-line \item labels in the Rd source).
+
+    * kappa() and rcond() work correctly in more cases; kappa(., norm =
+      "2") now warns that it computes the 1-norm with (default) exact =
+      FALSE; prompted by Mikael Jagan's quite comprehensive PR#18543.
+
+    * Rd skeletons generated by prompt() or promptData() now use a
+      dummy title (so R CMD build works).  tools::checkRdContents() has
+      been updated to detect such template leftovers, including from
+      promptPackage().
+
+    * When S4 method dispatch fails because no method was found, the
+      error message now includes the signature argument names; thanks
+      to Michael Chirico's proposal on R-devel.
+
+    * withAutoprint({ .. }) now preserves srcrefs previously lost,
+      thanks to Andrew Simmons' report plus fix in PR#18572.
+
+    * transform.data.frame() no longer adjusts names; in particular,
+      untransformed variables are kept as-is, including those with
+      syntactically invalid names (PR#17890).
+
+    * The keep.source option for Rd \Sexpr blocks is no longer ignored.
+
+    * The formula methods for t.test() and wilcox.test() now catch when
+      paired is passed, addressing PR#14359; use Pair(x1, x2) ~ 1 for a
+      paired test.
+
+    * The level reported in the browser prompt was often too large. It
+      now shows the number of browser contexts on the stack.
+
+    * For cbind() and rbind(), the optional deparse.level argument is
+      now properly passed to methods, thanks to Mikael Jagan's PR#18579
+      and comments there.
+
+    * Some error and warning messages for large ('long vector')
+      matrix(v, nr, nc) and dim(m) <- d are now correct about sizes,
+      using long long formatting, fixing PR#18612 (and more) reported
+      by Mikael Jagan.
+
+    * readChar(useBytes = TRUE) now terminates strings even when the
+      underlying connection uses extra spacea in the input buffer.
+      This fixes problems with extra garbage seen with gzip
+      connections, PR#18605.
+
+    * Named capture in PCRE regular expressions now works also with
+      more than 127 named groups (PR#18588).
+
+    * Datetime functions are now robust against long jumps when dealing
+      with internal time zone changes.  This avoids confusing warnings
+      about an invalid time zone, previously triggered by turning
+      warnings into errors or handling them via tryCatch (PR#17966,
+      PR#17780).
+
+    * Datetime functions now restore even an empty TZ environment
+      variable after internal time zone changes (PR#17724).  This makes
+      results of datetime functions with this (typically unintentional)
+      setting more predictable.
+
+    * drop.terms(*) now drops response as by default, keep.response =
+      FALSE, fixing PR#18564 thanks to Mikael Jagan.
+
+    * dummy.coef(.) now also works for lm()-models with character
+      categorical predictor variables rather than factor ones, fixing
+      PR#18635 reported by Jinsong Zhao.
+
+    * formals(f) <- formals(f) now also works for a function w/o

+CHANGES IN R 4.3.2 patched:
+
+  NEW FEATURES:
+
+    * iconv() now fixes up variant encoding names such as "utf8"
+      case-insensitively.
+
+  DEPRECATED AND DEFUNCT:
+
+    * The legacy encoding = "MacRoman" is deprecated in pdf() and
+      postscript(): support was incomplete in earlier versions of R.
+
+  BUG FIXES:
+
+    * Arguments are now properly forwarded to methods on S4 generics
+      with ... in the middle of their formal arguments. This was broken
+      for the case when a method introduced an argument but did not
+      include ... in its own formals. Thanks to Herv? Pag?s for the
+      report PR#18538.
+
+    * Some invalid file arguments to pictex(), postscript() and xfig()
+      opened a file called NA rather than throw an error.  These
+      included postscript(NULL) (which some people expected to work
+      like pdf(NULL)).
+
+    * Passing filename = NA to svg(), cairo_pdf(), cairo_ps() or the
+      Cairo-based bitmap devices opened a file called NA: it now throws
+      an error.
+
+    * quartz(file = NA) opened a file called NA, including when used as
+      a Quartz-based bitmap device.  It now gives an error.
+
+    * rank(<long vector>) now works, fixing PR#18617, thanks to Ilia
+      Kats.
+
+    * seq.int() did not adequately check its length.out argument.
+
+    * match(<POSIXct>, .) is correct again for differing time zones,
+      ditto for "POSIXlt", fixing PR#18618 reported by Bastian Klein.
+
+    * drop.terms(*, dropx = <0-length>) now works, fixing PR#18563 as
+      proposed by Mikael Jagan.
+
+    * drop.terms(*) keeps + offset(.) terms when it should, PR#18565,
+      and drop.terms() no longer makes up a response, PR#18566, fixing
+      both bugs thanks to Mikael Jagan.
+
+    * getS3method("t", "test") no longer finds the t.test() function,
+      fixing PR#18627.
+
+    * pdf() and postscript() support for the documented Adobe encodings
+      "Greek" and "Cyrilllic" was missing (although the corresponding
+      Windows' codepages could be used).
+
+    * Computations of glyph metric information for pdf() and
+      postscript() did not take into account that transliteration could
+      replace one character by two or more (only seen on macOS 14) and
+      typically warned that the information was not known.
+
+    * list.files() on Windows now returns also files with names longer
+      that 260 bytes (the Windows limit is 260 characters).
+      Previously, some file names particularly with 'East Asian'
+      characters were omitted.

+    \itemize{
+      \item Startup banners, \command{R --version}, \code{sessionInfo()}
+      and \command{R CMD check} no longer report \code{(64-bit)} as part of
+      the platform as this is almost universal -- the increasingly rare
+      32-bit platforms will still report \code{(32-bit)}.
+
+      On Windows, ditto for window titles.
+
+      \item \code{is.atomic(NULL)} now returns \code{FALSE}, as \code{NULL}
+      is not an atomic vector.  Strict back-compatibility would
+      replace \code{is.atomic(foo)} by \code{(is.null(foo) || is.atomic(foo))}
+      but should happen only sparingly.
+    }
+  }
+
+  \subsection{NEW FEATURES}{
+    \itemize{
+      \item The \code{confint()} methods for \code{"glm"} and
+      \code{"nls"} objects have been copied to the \pkg{stats}
+      package.  Previously, they were stubs which called versions in
+      package \pkg{MASS}. The \pkg{MASS} namespace is no longer loaded
+      if you invoke (say) \code{confint(glmfit)}.  Further, the
+      \code{"glm"} method for \code{profile()} and the \code{plot()}
+      and \code{pairs()} methods for class \code{"profile"} have been
+      copied from \pkg{MASS} to \pkg{stats}.  (\code{profile.nls()} and
+      \code{plot.profile.nls()} were already in \code{stats}.)
+
+      \item The \code{confint()} and \code{profile} methods for
+      \code{"glm"} objects have gained a possibility to do profiling
+      based on the Rao Score statistic in addition to the default
+      Likelihood Ratio. This is controlled by a new \code{test =}
+      argument.
+
+      \item The \code{"glm"} method for \code{anova()} computes test
+      statistics and p-values by default, using a chi-squared test or
+      an F test depending on whether the dispersion is fixed or
+      free.  Test statistics can be suppressed by giving argument
+      \code{test} a false logical value.
+
+      \item In \code{setRepositories()} the repositories can be set
+      using their names via \code{name =} instead of index \code{ind =}.
+
+      \item \code{methods()} and \code{.S3methods()} gain a
+      \code{all.names} option for the (rare) case where functions starting
+      with a \samp{.} should be included.
+
+      \item Serializations can now be interrupted (e.g., by \kbd{Ctrl-C} on
+      a Unix-alike) if they take too long, e.g., from \code{save.image()},
+      thanks to suggestions by Ivan Krylov and others on R-devel.
+
+      \item New startup option \option{--max-connections} to set the
+      maximum number of connections for the session.  Defaults to 128 as
+      before: allowed values up to 4096 (but resource limits may in practice
+      restrict to smaller values).
+
+      \item \R on Windows (since Windows 10 2004) now uses the new Segment
+      Heap allocator. This may improve performance of some memory-intensive
+      applications.
+
+      \item When \R packages are built, typically by \command{R CMD build <pkg>},
+      the new \command{--user=<build_user>} option overrides the
+      (internally determined) user name, currently \code{Sys.info()["user"]}
+      or \env{LOGNAME}.  This is a (modified) fulfillment of Will Landau's
+      suggestion in \PR{17530}.
+
+      \item \code{tools::testInstalledBasic()} gets new optional
+      arguments \code{outDir} and \code{testSrcdir}, e.g., allowing to use
+      it in a \code{\var{builddir} != \var{srcdir}} setup, and in standard
+      \dQuote{binary} Windows installation \bold{if} a source \file{tests/}
+      folder is present.
+
+      \item \code{range(<DT_with_Inf>, finite = TRUE)} now work for objects
+      of class \code{"Date"}, \code{"POSIXct"}, and \code{"POSIXlt"} with
+      infinite entries, analogously to \code{range.default()}, as proposed
+      by Davis Vaughan on R-devel.  Other \code{range()}-methods can make
+      use of new \code{.rangeNum()}.
+
+      \item New \code{.internalGenerics} complementing
+      \code{.S3PrimitiveGenerics}, for documentation and low-level book
+      keeping.
+
+      \item \code{grid()} now invisibly returns the x- and y- coordinates
+      at which the grid-lines were drawn.
+
+      \item \code{norm(., type)} now also works for complex matrices.
+
+      \item \code{kappa(., exact = TRUE, norm = *)} now works for all
+      norms and also for complex matrices.  In symmetric / triangular
+      cases, new argument \code{uplo = "U" | "L"} allows to specify the
+      upper or lower triangular part.
+
+      \item \code{memDecompress(type = "unknown")} recognizes compression
+      in the default \sQuote{zlib} format as used by
+      \code{memCompress(type = "gzip")}.
+
+      \item \code{memCompress()} and \code{memDecompress()} will use the
+      \code{libdeflate} library
+      (\url{https://github.com/ebiggers/libdeflate}) if installed.  This
+      uses the same type of compression for \code{type = "gzip"} but is
+      1.5-2x faster than the system \code{libz} library on some
+      common platforms: the speed-up may depend on the library version.
+      %% libdeflate 1.13 claims significant improvements in
+      %% decompression speed.
+
+      \item \code{diff()} for objects of class \code{"Date"},
+      \code{"POSIXct"}, and \code{"POSIXlt"} accepts a \code{units}
+      argument passed via \code{...}.
+
+      \item Dynamic help now does a much better job rendering package
+      \file{DESCRIPTION} metadata.
+
+      \item \code{Rprof()} gains an \code{event} argument and support
+      for elapsed (real) time profiling on Unix (\PR{18076}).
+
+      \item \code{filled.contour()} gains \code{key.border} argument.
+
+      \item \code{tools::update_pkg_po()} gets \code{pot_make} and
+      \code{mo_make} options for \emph{not} re-making the corresponding
+      files, and additionally option \code{verbose}.
+
+      \item Hexadecimal string colour specifications are now accepted
+      in short form, so, for example, we can use \code{"#123"}, which is
+      equivalent to \code{"#112233"}.
+
+      Thanks to MikeFC for the original idea and Ella Kaye, Malcolm
+      Barrett, George Stagg, and Hanne Oberman for the patch.
+
+      \item Plain-text help shows \verb{\var} markup with angle brackets.
+
+      \item The new experimental primitive function \code{declare()} is
+      intended to eventually allow information about R code to be
+      communicated to the interpreter, compiler, and code analysis
+      tools. The syntax for declarations is still being developed.
+
+      \item Functions \code{psmirnov()}, \code{qsmirnov()} and
+      \code{rsmirnov()} in package \pkg{stats} have argument
+      \code{two.sided} changed to \code{alternative}, to take into
+      account that the permutation distributions of the one-sided
+      statistics can be different in the case of ties.  Consequence of
+      \PR{18582}.
+
+      \item \code{sort()} is now an implicit S4 generic in \pkg{methods}.
+
+      \item Formatting and printing, \code{format(z), print(z)}, of complex
+      vectors \code{z} no longer zap relatively small real or imaginary
+      parts to zero, fixing \PR{16752}.  This is an API change, as it was
+      documented previously to round real and imaginary parts together on
+      purpose, producing nicer looking output.  As mentioned, e.g. in the
+      PR, this change is compatible to many other \dQuote{\R-like}
+      programming environments.
+
+      We have simplified the internal code and now basically format the
+      real and imaginary parts independently of each other.
+
+      \item New experimental functions \code{Tailcall} and \code{Exec}
+      to support writing stack-space-efficient recursive functions.
+
+      \item Where characters are attempted to be plotted by
+      \code{pdf()}, \code{postscript()} and \code{xfig()} which are
+      not in the selected 8-bit character set (most often Latin-1) and
+      the \R session is using a UTF-8 locale, the warning messages will
+      show the UTF-8 character rather than its bytes and one dot will be
+      substituted per character rather than per byte.  (Platforms whose
+      \code{iconv()} does transliteration silently plot the
+      transliteration.)
+
+      In a UTF-8 locale some transliterations are now done with a
+      warning (e.g., dashes and Unicode minus to hyphen, ligatures are
+      expanded, permille (\samp{‰}) is replaced by \samp{o/oo}),
+      although the OS may have got there first.  These are warnings as
+      they will continue to be replaced by dots in earlier versions of
+      \R.
+
+      \item The matrix multiplication functions \code{crossprod()} and
+      \code{tcrossprod()} are now also primitive and S3 generic, as
+      \code{\%*\%} had become in \R 4.3.0.
+
+      \item \code{source()} and \code{example()} have a new optional
+      argument \code{catch.aborts} which allows continued evaluation of
+      the \R code after an error.
+
+      \item The non-Quartz \code{tiff()} devices allow additional types
+      of compression if supported by the platform's \samp{libtiff} library.
+
+      \item The list of base and recommended package names is now provided by
+      \code{tools :: standard_package_names}.
+
+      \item \code{cairo_pdf()} and \code{cairo_ps()} default to
+      \code{onefile = TRUE} to closer match \code{pdf()} and
+      \code{postscript()}.
+
+      \item New option \code{catch.script.errors} provides a documented way
+      to catch errors and continue in non-interactive use.
+
+      \item \code{L \%||\% R} newly in base is an expressive idiom for the
+      \code{if(!is.null(L)) L else R} or \code{if(is.null(L)) R else L}
+      phrases.
+
+      \item \code{warnings()} now always inherits from \code{"warnings"} as
+      documented, newly also in the case of no warnings, where it
+      previously returned \code{NULL}.
+
+      \item \code{as.complex("1i")} now returns \code{1i} instead of
+      \code{NA} with a warning.
+
+      \item \code{z <- c(NA, 1i)} now keeps the imaginary part
+      \code{Im(z[1]) == 0}, no longer coercing to \code{NA_complex_}.
+      Similarly, \code{cumsum(z)} correctly sums real and imaginary parts
+      separately, i.e., without \dQuote{crosstalk} in case of \code{NA}s.
+
+      \item On Alpine Linux \code{iconv()} now maps \code{"latin2"},
+      \code{"latin-2"}, \code{"latin9"} and \code{"latin-9"} to names
+      the OS knows about (case-insensitively).
+
+      \item \code{iconv(sub = "Unicode")} now zero-pads to four (hex)
+      digits, rather than to 4 or 8.  (This seems to have become the
+      convention once Unicode restricted the number of Unicode points
+      to \eqn{2{^31} - 1}{2^31 - 1} and so will never need more than 6
+      digits.)
+
+      \item \code{NCOL(NULL)} now returns 0 instead of 1, for
+      consistency with \code{cbind()}.
+
+      \item Support for \code{encoding = "MacRoman"} has been removed
+      from the \code{pdf()} and \code{postscript()} devices -- this was
+      a legacy encoding supporting classic macOS up to 2001 (with
+      various revisions), and no longer has universal \code{libiconv}
+      support.%% e.g. not in musl

+
+  \subsection{INSTALLATION on a UNIX-ALIKE}{
+    \itemize{
+      \item System valgrind headers are required to use
+      \command{configure} option \option{--with-valgrind-instrumentation}
+      with value \code{1} or \code{2}.
+
+      \item \command{configure} will warn if it encounters a 32-bit
+      build, as that is nowadays almost untested.
+
+      \item Environment variable \env{R_SYSTEM_ABI} is no longer used and
+      so no longer recorded in \file{etc/Renviron} (it was not on Windows
+      and was only ever used when preparing package \pkg{tools}).
+
+      \item If the \code{libdeflate} library and headers are available,
+      \code{libdeflate} rather than \code{libz} is used to (de)compress
+      \R objects in lazy-load databases,  Typically tasks spend up to 5\% of
+      their time on such operations, although creating lazy-data
+      databases is one of the exceptions.
+
+      This can be suppressed if the library is available by the
+      \command{configure} option
+      \option{--without-libdeflate-compression}.
+
+      \item \command{configure} option \option{--enable-lto=check} has
+      not worked reliably since 2019 and has been removed.
+    }
+  }
+
+  \subsection{INSTALLATION on macOS}{
+    \itemize{
+      \item A new \command{configure} option \option{--with-newAccelerate}
+      makes use of Apple's \sQuote{new} BLAS / LAPACK interfaces in their
+      Accelerate framework.  Those interfaces are only available in macOS
+      13.3 or later, and building requires SDK 13.3 or later (from the
+      Command Line Tools or Xcode 14.3 or later).
+
+      By default the option uses new Accelerate for BLAS calls: to also
+      use it for LAPACK use \option{--with-newAccelerate=lapack}.  The
+      later interfaces provide LAPACK 3.9.1 rather than 3.2.1: 3.9.1 is
+      from 2021-04 and does not include the improved algorithms
+      introduced in LAPACK 3.10.0 (including for BLAS calls).

+
+  \subsection{UTILITIES}{
+    \itemize{
+      \item \command{R CMD check} notes when S4-style exports are used
+      without declaring a strong dependence on package \pkg{methods}.
+
+      \item \code{tools::checkRd()} (used by \command{R CMD check})
+      detects more problems with \verb{\Sexpr}-based dynamic content,
+      including bad nesting of \verb{\Sexpr}s and invalid arguments.
+
+      \item \code{tools::checkRd()} now reports Rd titles and section
+      names ending in a period; this is ignored by \command{R CMD check}
+      unless environment variable \env{_R_CHECK_RD_CHECKRD_MINLEVEL_} is
+      set to -5 or smaller.
+
+      \item \command{R CMD check} now notes Rd files without an
+      \verb{\alias}, as long documented in \sQuote{Writing R Extensions}
+      §1.3.1.
+      The check for a missing \verb{\description} has been moved from
+      \code{tools::checkRd()} to \code{tools::checkRdContents()}.
+
+      \item \command{R CMD check} now visits \file{inst/NEWS.Rd}
+      when checking Rd files.
+
+      \item \code{tools::checkDocFiles()} and
+      \code{tools::checkRdContents()} now also check internal Rd files
+      by default, but \dQuote{specially} (ignoring missing documentation
+      of arguments).
+
+      \item \command{R CMD Rdiff} gets option \option{--useEx}.
+
+      \item \command{R CMD check} now warns on non-portable uses of
+      Fortran \code{KIND} such as \code{INTEGER(KIND=4)} and
+      \code{REAL(KIND=8)}.
+
+      To see the failing lines set environment variable
+      \env{_R_CHECK_FORTRAN_KIND_DETAILS_} to a true value.
+
+      \item When checking Rd files, \command{R CMD check --as-cran} now
+      notes some of the \dQuote{lost braces} that
+      \code{tools::checkRd()} finds.  Typical problems are Rd macros
+      missing the initial backslash (e.g., \samp{code{...}}), in-text
+      set notation (e.g., \samp{{1, 2}}, where the braces need
+      escaping), and \verb{\itemize} lists with \emph{description}-like
+      entries of the form \verb{\item{label}{description}}.
+    }
+  }
+
+  \subsection{C-LEVEL FACILITIES}{
+    \itemize{
+      \item Headers \file{R_ext/Applic.h} and \file{R-ext/Linpack.h}
+      used to include \file{R_ext/BLAS.h} although this was undocumented and
+      unneeded by their documented entry points.  They no longer do so.
+
+      \item New \code{R_missing()}, factored out from \code{do_missing()},
+      used to fix \PR{18579}.
+
+      \item \code{SEXP} type \code{S4SXP} has been renamed \code{OBJSXP}
+      to support experimenting with alternative object systems.  The
+      \code{S4SXP} value can still be used in \code{C} code but is now
+      deprecated. Based on contributions from the R Consortium
+      Object-Oriented Programming Working Group.
+    }
+  }
+
+  \subsection{DEPRECATED AND DEFUNCT}{
+    \itemize{
+      \item \code{data()} no longer handles zipped data from
+      long-defunct (since \R 2.13.0) \option{--use-zip-data} installations.
+
+      \item The legacy graphics devices \code{pictex()} and
+      \code{xfig()} are now deprecated.  They do not support recent
+      graphics enhancements and their font-handling is rudimentary. The
+      intention is to retain them for historical interest as long as
+      they remain somewhat functional.
+    }
+  }
+
+  \subsection{BUG FIXES}{
+    \itemize{
+      \item The methods package is more robust to not being attached to
+      the search path. More work needs to be done.
+
+      \item \code{pairwise.t.test()} misbehaved when subgroups had 0 DF
+      for variance, even with \code{pool.sd=TRUE} \PR{18594} (Jack Berry).
+
+      \item Probability distribution functions \code{[dpq]<distrib>(x, *)},
+      but also \code{bessel[IKJY](x, .)} are now consistently preserving
+      \code{attributes(x)} when \code{length(x) == 0}, e.g., for a
+      \eqn{2 \times 0}{2 x 0} matrix, thanks to Karolis Koncevičius'
+      report \PR{18509}.
+
+      \item Group \dQuote{Summary} computations such as
+      \code{sum(1:3, 4, na.rm = 5, NA, 7, na.rm = LL)} now give an error
+      instead of either \code{17} or \code{NN} for \code{LL} true or false,
+      as proposed by Ivan Krylov on the R-devel mailing list.  (This
+      also means it is now an error to specify \code{na.rm} more than once.)
+
+      \item \code{as.complex(x)} now returns \code{complex(real=x,
+      imaginary=0)} for \emph{all} numerical and logical \code{x}, notably
+      also for \code{NA} or \code{NA_integer_}.
+
+      \item Directories are now omitted by
+      \code{file.copy(,recursive = FALSE)} and in \code{file.append()}
+      (\PR{17337}).
+
+      \item \code{gsub()} and \code{sub()} are now more robust to integer
+      overflow when reporting errors caused by too large input strings
+      (\PR{18346}).
+
+      \item Top-level handlers are now more robust to attempts to remove a
+      handler whilst handlers are running (\PR{18508}).
+
+      \item The handling of \code{Alt+F4} in dialogs created on Windows using
+      GraphApp has been fixed (\PR{13870}).
+
+      \item \code{density()} more consistently computes grid values for the
+      FFT-based convolution, following Robert Schlicht's analysis and
+      proposal in \PR{18337}, correcting density values typically by a
+      factor of about 0.999.  Optional \code{old.coords=TRUE} provides
+      back compatibility.
+
+      \item \code{palette.colors()} gains a \code{name} argument that
+      defaults to \code{FALSE} controlling whether the vector of colours
+      that is returned has names (where possible).  \PR{18529}.
+
+      \item \code{tools::xgettext()} no longer extracts the
+      (non-translatable) class names from \code{warningCondition} and
+      \code{errorCondition} calls.
+
+      \item \code{S3method(<gen>, <class>, <func>)} in the \file{NAMESPACE}
+      file now works (again) when \code{<func>} is visible from the
+      namespace, e.g., imported, or in base.
+
+      \item \code{getParseData(f)} now also works for a function defined
+      in the first of several \file{<pkg>/R/*.R} source files, thanks to
+      Kirill Müller's report and Duncan Murdoch's patch in \PR{16756}.
+
+      \item Rd \verb{\Sexpr} macros with nested \verb{#ifdef}
+      conditionals were not processed.
+
+      \item A non-blocking connection with non-default encoding such as
+      a socket, now correctly returns from \code{readLines()} after new
+      data has arrived also when its \code{EOF} had been reached
+      previously.  Thanks to Peter Meilstrup's report on R-devel and
+      Ivan Krylov's report and patch proposal in \PR{18555}.
+
+      \item \code{tools::checkRdContents()} failed to detect empty
+      argument descriptions when they spanned multiple lines,
+      including those generated by \code{prompt()}.
+      These cases are now noted by \command{R CMD check}.
+
+      \item Plain-text help no longer outputs spurious colons in the
+      arguments list (for multi-line \verb{\item} labels in the Rd source).
+
+      \item \code{kappa()} and \code{rcond()} work correctly in more cases;
+      \code{kappa(., norm = "2")} now warns that it computes the 1-norm with
+      (default) \code{exact = FALSE}; prompted by Mikael Jagan's quite
+      comprehensive \PR{18543}.
+
+      \item Rd skeletons generated by \code{prompt()} or
+      \code{promptData()} now use a dummy title (so \command{R CMD
+      build} works).  \code{tools::checkRdContents()} has been updated
+      to detect such template leftovers, including from
+      \code{promptPackage()}.
+
+      \item When S4 method dispatch fails because no method was found, the
+      error message now includes the signature argument names; thanks to
+      Michael Chirico's proposal on R-devel.
+
+      \item \code{withAutoprint({ .. })} now preserves \code{srcref}s
+      previously lost, thanks to Andrew Simmons' report plus fix in
+      \PR{18572}.
+
+      \item \code{transform.data.frame()} no longer adjusts names;
+      in particular, untransformed variables are kept as-is,
+      including those with syntactically invalid names (\PR{17890}).
+
+      \item The \code{keep.source} option for Rd \verb{\Sexpr} blocks is
+      no longer ignored.
+
+      \item The \code{formula} methods for \code{t.test()} and
+      \code{wilcox.test()} now catch when \code{paired} is passed,
+      addressing \PR{14359}; use \code{Pair(x1, x2) ~ 1} for a paired test.
+
+      \item The level reported in the browser prompt was often too
+      large. It now shows the number of browser contexts on the stack.
+
+      \item For \code{cbind()} and \code{rbind()}, the optional
+      \code{deparse.level} argument is now properly passed to methods,
+      thanks to Mikael Jagan's \PR{18579} and comments there.
+
+      \item Some error and warning messages for large (\sQuote{long
+	vector}) \code{matrix(v, nr, nc)} and \code{dim(m) <- d} are now
+      correct about sizes, using \code{long long} formatting, fixing
+      \PR{18612} (and more) reported by Mikael Jagan.
+      \item \code{readChar(useBytes = TRUE)} now terminates strings even when
+      the underlying connection uses extra spacea in the input buffer.  This
+      fixes problems with extra garbage seen with \command{gzip}
+      connections, \PR{18605}.
+
+      \item Named capture in PCRE regular expressions now works also with
+      more than 127 named groups (\PR{18588}).
+
+      \item Datetime functions are now robust against long jumps when
+      dealing with internal time zone changes.  This avoids confusing
+      warnings about an invalid time zone, previously triggered by turning
+      warnings into errors or handling them via \code{tryCatch} (\PR{17966},
+      \PR{17780}).
+
+      \item Datetime functions now restore even an empty \env{TZ}
+      environment variable after internal time zone changes (\PR{17724}).
+      This makes results of datetime functions with this (typically
+      unintentional) setting more predictable.
+
+      \item \code{drop.terms(*)} now drops response as by default,
+      \code{keep.response = FALSE}, fixing \PR{18564} thanks to Mikael Jagan.
+
+      \item \code{dummy.coef(.)} now also works for \code{lm()}-models with
+      \code{character} categorical predictor variables rather than
+      \code{factor} ones, fixing \PR{18635} reported by Jinsong Zhao.
+
+      \item \code{formals(f) <- formals(f)} now also works for a function
+      w/o arguments and atomic \emph{constant} \code{body(f)}.
+
+      \item Correct \code{as.function(<invalid list>, .)}'s error message.

+
+  \subsection{BUG FIXES}{
+    \itemize{
+      \item Arguments are now properly forwarded to methods on S4 generics
+      with \dots{} in the middle of their formal arguments. This was
+      broken for the case when a method introduced an argument but did
+      not include \dots{} in its own formals. Thanks to Hervé Pagès for
+      the report \PR{18538}.
+
+      \item Some invalid \code{file} arguments to \code{pictex()},
+      \code{postscript()} and \code{xfig()} opened a file called
+      \samp{NA} rather than throw an error.  These included
+      \code{postscript(NULL)} (which some people expected to work like
+      \code{pdf(NULL)}).
+
+      \item Passing \code{filename = NA} to \code{svg()}, \code{cairo_pdf()},
+      \code{cairo_ps()} or the Cairo-based bitmap devices opened a file
+      called \samp{NA}: it now throws an error.
+
+      \item \code{quartz(file = NA)} opened a file called \samp{NA}, including
+      when used as a Quartz-based bitmap device.  It now gives an error.
+
+      \item \code{rank(<long vector>)} now works, fixing \PR{18617}, thanks to
+      Ilia Kats.
+
+      \item \code{seq.int()} did not adequately check its
+      \code{length.out} argument.
+
+      \item \code{match(<POSIXct>, .)} is correct again for differing time
+      zones, ditto for \code{"POSIXlt"}, fixing \PR{18618} reported by
+      Bastian Klein.
+
+      \item \code{drop.terms(*, dropx = <0-length>)} now works, fixing
+      \PR{18563} as proposed by Mikael Jagan.
+
+      \item \code{drop.terms(*)} keeps \code{ + offset(.)} terms when it should,
+      \PR{18565}, and \code{drop.terms()} no longer makes up a response,

+
+      \item \code{getS3method("t", "test")} no longer finds the

+
+      \item \code{pdf()} and \code{postscript()} support for the documented
+      Adobe encodings \code{"Greek"} and \code{"Cyrilllic"} was missing
+      (although the corresponding Windows' codepages could be used).
+

+<li><p> Startup banners, <code>R --version</code>, <code>sessionInfo()</code>
+and <code>R CMD check</code> no longer report <code>(64-bit)</code> as part of
+the platform as this is almost universal &ndash; the increasingly rare

+but should happen only sparingly.
+</p>
+</li></ul>
+
+
+
+
+<h4>NEW FEATURES</h4>
+
+
+<ul>
+<li><p> The <code>confint()</code> methods for <code>"glm"</code> and
+<code>"nls"</code> objects have been copied to the <span class="pkg">stats</span>
+package.  Previously, they were stubs which called versions in
+package <span class="pkg">MASS</span>. The <span class="pkg">MASS</span> namespace is no longer loaded
+if you invoke (say) <code>confint(glmfit)</code>.  Further, the
+<code>"glm"</code> method for <code>profile()</code> and the <code>plot()</code>
+and <code>pairs()</code> methods for class <code>"profile"</code> have been
+copied from <span class="pkg">MASS</span> to <span class="pkg">stats</span>.  (<code>profile.nls()</code> and
+<code>plot.profile.nls()</code> were already in <code>stats</code>.)
+</p>
+</li>
+<li><p> The <code>confint()</code> and <code>profile</code> methods for
+<code>"glm"</code> objects have gained a possibility to do profiling
+based on the Rao Score statistic in addition to the default
+Likelihood Ratio. This is controlled by a new <code>test =</code>
+argument.
+</p>
+</li>
+<li><p> The <code>"glm"</code> method for <code>anova()</code> computes test
+statistics and p-values by default, using a chi-squared test or
+an F test depending on whether the dispersion is fixed or
+free.  Test statistics can be suppressed by giving argument
+<code>test</code> a false logical value.
+</p>
+</li>
+<li><p> In <code>setRepositories()</code> the repositories can be set
+using their names via <code>name =</code> instead of index <code>ind =</code>.
+</p>
+</li>
+<li> <p><code>methods()</code> and <code>.S3methods()</code> gain a
+<code>all.names</code> option for the (rare) case where functions starting
+with a &lsquo;<span class="samp">&#8288;.&#8288;</span>&rsquo; should be included.
+</p>
+</li>
+<li><p> Serializations can now be interrupted (e.g., by <kbd>Ctrl-C</kbd> on
+a Unix-alike) if they take too long, e.g., from <code>save.image()</code>,
+thanks to suggestions by Ivan Krylov and others on R-devel.
+</p>
+</li>
+<li><p> New startup option <span class="option">--max-connections</span> to set the
+maximum number of connections for the session.  Defaults to 128 as
+before: allowed values up to 4096 (but resource limits may in practice
+restrict to smaller values).
+</p>
+</li>
+<li> <p><span class="rlang"><b>R</b></span> on Windows (since Windows 10 2004) now uses the new Segment
+Heap allocator. This may improve performance of some memory-intensive
+applications.
+</p>
+</li>
+<li><p> When <span class="rlang"><b>R</b></span> packages are built, typically by <code>R CMD build &lt;pkg&gt;</code>,
+the new <code>--user=&lt;build_user&gt;</code> option overrides the
+(internally determined) user name, currently <code>Sys.info()["user"]</code>
+or <span class="env">LOGNAME</span>.  This is a (modified) fulfillment of Will Landau's
+suggestion in <a href="https://bugs.R-project.org/show_bug.cgi?id=17530">PR#17530</a>.
+</p>
+</li>
+<li> <p><code>tools::testInstalledBasic()</code> gets new optional
+arguments <code>outDir</code> and <code>testSrcdir</code>, e.g., allowing to use
+it in a <code><var>builddir</var> != <var>srcdir</var></code> setup, and in standard
+&ldquo;binary&rdquo; Windows installation <b>if</b> a source &lsquo;<span class="file">tests/</span>&rsquo;
+folder is present.
+</p>
+</li>
+<li> <p><code>range(&lt;DT_with_Inf&gt;, finite = TRUE)</code> now work for objects
+of class <code>"Date"</code>, <code>"POSIXct"</code>, and <code>"POSIXlt"</code> with
+infinite entries, analogously to <code>range.default()</code>, as proposed
+by Davis Vaughan on R-devel.  Other <code>range()</code>-methods can make
+use of new <code>.rangeNum()</code>.
+</p>
+</li>
+<li><p> New <code>.internalGenerics</code> complementing
+<code>.S3PrimitiveGenerics</code>, for documentation and low-level book
+keeping.
+</p>
+</li>
+<li> <p><code>grid()</code> now invisibly returns the x- and y- coordinates
+at which the grid-lines were drawn.
+</p>
+</li>
+<li> <p><code>norm(., type)</code> now also works for complex matrices.
+</p>
+</li>
+<li> <p><code>kappa(., exact = TRUE, norm = *)</code> now works for all
+norms and also for complex matrices.  In symmetric / triangular
+cases, new argument <code>uplo = "U" | "L"</code> allows to specify the
+upper or lower triangular part.
+</p>
+</li>
+<li> <p><code>memDecompress(type = "unknown")</code> recognizes compression
+in the default &lsquo;zlib&rsquo; format as used by
+<code>memCompress(type = "gzip")</code>.
+</p>
+</li>
+<li> <p><code>memCompress()</code> and <code>memDecompress()</code> will use the
+<code>libdeflate</code> library
+(<a href="https://github.com/ebiggers/libdeflate">https://github.com/ebiggers/libdeflate</a>) if installed.  This
+uses the same type of compression for <code>type = "gzip"</code> but is
+1.5-2x faster than the system <code>libz</code> library on some
+common platforms: the speed-up may depend on the library version.
+
+
+</p>
+</li>
+<li> <p><code>diff()</code> for objects of class <code>"Date"</code>,
+<code>"POSIXct"</code>, and <code>"POSIXlt"</code> accepts a <code>units</code>
+argument passed via <code>...</code>.
+</p>
+</li>
+<li><p> Dynamic help now does a much better job rendering package
+&lsquo;<span class="file">DESCRIPTION</span>&rsquo; metadata.
+</p>
+</li>
+<li> <p><code>Rprof()</code> gains an <code>event</code> argument and support
+for elapsed (real) time profiling on Unix (<a href="https://bugs.R-project.org/show_bug.cgi?id=18076">PR#18076</a>).
+</p>
+</li>
+<li> <p><code>filled.contour()</code> gains <code>key.border</code> argument.
+</p>
+</li>
+<li> <p><code>tools::update_pkg_po()</code> gets <code>pot_make</code> and
+<code>mo_make</code> options for <em>not</em> re-making the corresponding
+files, and additionally option <code>verbose</code>.
+</p>
+</li>
+<li><p> Hexadecimal string colour specifications are now accepted
+in short form, so, for example, we can use <code>"#123"</code>, which is
+equivalent to <code>"#112233"</code>.
+</p>
+<p>Thanks to MikeFC for the original idea and Ella Kaye, Malcolm
+Barrett, George Stagg, and Hanne Oberman for the patch.
+</p>
+</li>
+<li><p> Plain-text help shows <code style="white-space: pre;">&#8288;\var&#8288;</code> markup with angle brackets.
+</p>
+</li>
+<li><p> The new experimental primitive function <code>declare()</code> is
+intended to eventually allow information about R code to be
+communicated to the interpreter, compiler, and code analysis
+tools. The syntax for declarations is still being developed.
+</p>
+</li>
+<li><p> Functions <code>psmirnov()</code>, <code>qsmirnov()</code> and
+<code>rsmirnov()</code> in package <span class="pkg">stats</span> have argument
+<code>two.sided</code> changed to <code>alternative</code>, to take into
+account that the permutation distributions of the one-sided
+statistics can be different in the case of ties.  Consequence of
+<a href="https://bugs.R-project.org/show_bug.cgi?id=18582">PR#18582</a>.
+</p>
+</li>
+<li> <p><code>sort()</code> is now an implicit S4 generic in <span class="pkg">methods</span>.
+</p>
+</li>
+<li><p> Formatting and printing, <code>format(z), print(z)</code>, of complex
+vectors <code>z</code> no longer zap relatively small real or imaginary
+parts to zero, fixing <a href="https://bugs.R-project.org/show_bug.cgi?id=16752">PR#16752</a>.  This is an API change, as it was
+documented previously to round real and imaginary parts together on
+purpose, producing nicer looking output.  As mentioned, e.g. in the
+PR, this change is compatible to many other &ldquo;<span class="rlang"><b>R</b></span>-like&rdquo;
+programming environments.
+</p>
+<p>We have simplified the internal code and now basically format the
+real and imaginary parts independently of each other.
+</p>
+</li>
+<li><p> New experimental functions <code>Tailcall</code> and <code>Exec</code>
+to support writing stack-space-efficient recursive functions.
+</p>
+</li>
+<li><p> Where characters are attempted to be plotted by
+<code>pdf()</code>, <code>postscript()</code> and <code>xfig()</code> which are
+not in the selected 8-bit character set (most often Latin-1) and
+the <span class="rlang"><b>R</b></span> session is using a UTF-8 locale, the warning messages will
+show the UTF-8 character rather than its bytes and one dot will be
+substituted per character rather than per byte.  (Platforms whose
+<code>iconv()</code> does transliteration silently plot the
+transliteration.)
+</p>
+<p>In a UTF-8 locale some transliterations are now done with a
+warning (e.g., dashes and Unicode minus to hyphen, ligatures are
+expanded, permille (&lsquo;<span class="samp">&#8288;‰&#8288;</span>&rsquo;) is replaced by &lsquo;<span class="samp">&#8288;o/oo&#8288;</span>&rsquo;),
+although the OS may have got there first.  These are warnings as
+they will continue to be replaced by dots in earlier versions of
+<span class="rlang"><b>R</b></span>.
+</p>
+</li>
+<li><p> The matrix multiplication functions <code>crossprod()</code> and
+<code>tcrossprod()</code> are now also primitive and S3 generic, as
+<code>%*%</code> had become in <span class="rlang"><b>R</b></span> 4.3.0.
+</p>
+</li>
+<li> <p><code>source()</code> and <code>example()</code> have a new optional
+argument <code>catch.aborts</code> which allows continued evaluation of
+the <span class="rlang"><b>R</b></span> code after an error.
+</p>
+</li>
+<li><p> The non-Quartz <code>tiff()</code> devices allow additional types
+of compression if supported by the platform's &lsquo;<span class="samp">&#8288;libtiff&#8288;</span>&rsquo; library.
+</p>
+</li>
+<li><p> The list of base and recommended package names is now provided by
+<code>tools :: standard_package_names</code>.
+</p>
+</li>
+<li> <p><code>cairo_pdf()</code> and <code>cairo_ps()</code> default to
+<code>onefile = TRUE</code> to closer match <code>pdf()</code> and
+<code>postscript()</code>.
+</p>
+</li>
+<li><p> New option <code>catch.script.errors</code> provides a documented way
+to catch errors and continue in non-interactive use.
+</p>
+</li>
+<li> <p><code>L %||% R</code> newly in base is an expressive idiom for the
+<code>if(!is.null(L)) L else R</code> or <code>if(is.null(L)) R else L</code>
+phrases.
+</p>
+</li>
+<li> <p><code>warnings()</code> now always inherits from <code>"warnings"</code> as
+documented, newly also in the case of no warnings, where it
+previously returned <code>NULL</code>.
+</p>
+</li>
+<li> <p><code>as.complex("1i")</code> now returns <code>1i</code> instead of
+<code>NA</code> with a warning.
+</p>
+</li>
+<li> <p><code>z &lt;- c(NA, 1i)</code> now keeps the imaginary part
+<code>Im(z[1]) == 0</code>, no longer coercing to <code>NA_complex_</code>.
+Similarly, <code>cumsum(z)</code> correctly sums real and imaginary parts
+separately, i.e., without &ldquo;crosstalk&rdquo; in case of <code>NA</code>s.
+</p>
+</li>
+<li><p> On Alpine Linux <code>iconv()</code> now maps <code>"latin2"</code>,
+<code>"latin-2"</code>, <code>"latin9"</code> and <code>"latin-9"</code> to names
+the OS knows about (case-insensitively).
+</p>
+</li>
+<li> <p><code>iconv(sub = "Unicode")</code> now zero-pads to four (hex)
+digits, rather than to 4 or 8.  (This seems to have become the
+convention once Unicode restricted the number of Unicode points
+to <code class="reqn">2{^31} - 1</code> and so will never need more than 6
+digits.)
+</p>
+</li>
+<li> <p><code>NCOL(NULL)</code> now returns 0 instead of 1, for
+consistency with <code>cbind()</code>.
+</p>
+</li>
+<li><p> Support for <code>encoding = "MacRoman"</code> has been removed
+from the <code>pdf()</code> and <code>postscript()</code> devices &ndash; this was
+a legacy encoding supporting classic macOS up to 2001 (with
+various revisions), and no longer has universal <code>libiconv</code>
+support.
+</p>
+</li></ul>
+
+
+
+
+<h4>INSTALLATION on a UNIX-ALIKE</h4>
+
+
+<ul>
+<li><p> System valgrind headers are required to use
+<code>configure</code> option <span class="option">--with-valgrind-instrumentation</span>
+with value <code>1</code> or <code>2</code>.
+</p>
+</li>
+<li> <p><code>configure</code> will warn if it encounters a 32-bit
+build, as that is nowadays almost untested.
+</p>
+</li>
+<li><p> Environment variable <span class="env">R_SYSTEM_ABI</span> is no longer used and
+so no longer recorded in &lsquo;<span class="file">etc/Renviron</span>&rsquo; (it was not on Windows
+and was only ever used when preparing package <span class="pkg">tools</span>).
+</p>
+</li>
+<li><p> If the <code>libdeflate</code> library and headers are available,
+<code>libdeflate</code> rather than <code>libz</code> is used to (de)compress
+<span class="rlang"><b>R</b></span> objects in lazy-load databases,  Typically tasks spend up to 5% of
+their time on such operations, although creating lazy-data
+databases is one of the exceptions.
+</p>
+<p>This can be suppressed if the library is available by the
+<code>configure</code> option
+<span class="option">--without-libdeflate-compression</span>.
+</p>
+</li>
+<li> <p><code>configure</code> option <span class="option">--enable-lto=check</span> has
+not worked reliably since 2019 and has been removed.
+</p>
+</li></ul>
+
+
+
+
+<h4>INSTALLATION on macOS</h4>
+
+
+<ul>
+<li><p> A new <code>configure</code> option <span class="option">--with-newAccelerate</span>
+makes use of Apple's &lsquo;new&rsquo; BLAS / LAPACK interfaces in their
+Accelerate framework.  Those interfaces are only available in macOS
+13.3 or later, and building requires SDK 13.3 or later (from the
+Command Line Tools or Xcode 14.3 or later).
+</p>
+<p>By default the option uses new Accelerate for BLAS calls: to also
+use it for LAPACK use <span class="option">--with-newAccelerate=lapack</span>.  The
+later interfaces provide LAPACK 3.9.1 rather than 3.2.1: 3.9.1 is
+from 2021-04 and does not include the improved algorithms
+introduced in LAPACK 3.10.0 (including for BLAS calls).
+</p>
+</li></ul>
+
+
+
+
+
+
+
+
+
+<h4>UTILITIES</h4>
+
+
+<ul>
+<li> <p><code>R CMD check</code> notes when S4-style exports are used
+without declaring a strong dependence on package <span class="pkg">methods</span>.
+</p>
+</li>
+<li> <p><code>tools::checkRd()</code> (used by <code>R CMD check</code>)
+detects more problems with <code style="white-space: pre;">&#8288;\Sexpr&#8288;</code>-based dynamic content,
+including bad nesting of <code style="white-space: pre;">&#8288;\Sexpr&#8288;</code>s and invalid arguments.
+</p>
+</li>
+<li> <p><code>tools::checkRd()</code> now reports Rd titles and section
+names ending in a period; this is ignored by <code>R CMD check</code>
+unless environment variable <span class="env">_R_CHECK_RD_CHECKRD_MINLEVEL_</span> is
+set to -5 or smaller.
+</p>
+</li>
+<li> <p><code>R CMD check</code> now notes Rd files without an
+<code style="white-space: pre;">&#8288;\alias&#8288;</code>, as long documented in &lsquo;Writing R Extensions&rsquo;
+§1.3.1.
+The check for a missing <code style="white-space: pre;">&#8288;\description&#8288;</code> has been moved from
+<code>tools::checkRd()</code> to <code>tools::checkRdContents()</code>.
+</p>
+</li>
+<li> <p><code>R CMD check</code> now visits &lsquo;<span class="file">inst/NEWS.Rd</span>&rsquo;
+when checking Rd files.
+</p>
+</li>
+<li> <p><code>tools::checkDocFiles()</code> and
+<code>tools::checkRdContents()</code> now also check internal Rd files
+by default, but &ldquo;specially&rdquo; (ignoring missing documentation
+of arguments).
+</p>
+</li>
+<li> <p><code>R CMD Rdiff</code> gets option <span class="option">--useEx</span>.
+</p>
+</li>
+<li> <p><code>R CMD check</code> now warns on non-portable uses of
+Fortran <code>KIND</code> such as <code>INTEGER(KIND=4)</code> and
+<code>REAL(KIND=8)</code>.
+</p>
+<p>To see the failing lines set environment variable
+<span class="env">_R_CHECK_FORTRAN_KIND_DETAILS_</span> to a true value.
+</p>
+</li>
+<li><p> When checking Rd files, <code>R CMD check --as-cran</code> now
+notes some of the &ldquo;lost braces&rdquo; that
+<code>tools::checkRd()</code> finds.  Typical problems are Rd macros
+missing the initial backslash (e.g., &lsquo;<span class="samp">&#8288;code{...}&#8288;</span>&rsquo;), in-text
+set notation (e.g., &lsquo;<span class="samp">&#8288;{1, 2}&#8288;</span>&rsquo;, where the braces need
+escaping), and <code style="white-space: pre;">&#8288;\itemize&#8288;</code> lists with <em>description</em>-like
+entries of the form <code style="white-space: pre;">&#8288;\item{label}{description}&#8288;</code>.
+</p>
+</li></ul>
+
+
+
+
+<h4>C-LEVEL FACILITIES</h4>
+
+
+<ul>
+<li><p> Headers &lsquo;<span class="file">R_ext/Applic.h</span>&rsquo; and &lsquo;<span class="file">R-ext/Linpack.h</span>&rsquo;
+used to include &lsquo;<span class="file">R_ext/BLAS.h</span>&rsquo; although this was undocumented and
+unneeded by their documented entry points.  They no longer do so.
+</p>
+</li>
+<li><p> New <code>R_missing()</code>, factored out from <code>do_missing()</code>,
+used to fix <a href="https://bugs.R-project.org/show_bug.cgi?id=18579">PR#18579</a>.
+</p>
+</li>
+<li> <p><code>SEXP</code> type <code>S4SXP</code> has been renamed <code>OBJSXP</code>
+to support experimenting with alternative object systems.  The
+<code>S4SXP</code> value can still be used in <code>C</code> code but is now
+deprecated. Based on contributions from the R Consortium
+Object-Oriented Programming Working Group.
+</p>
+</li></ul>
+
+
+
+
+<h4>DEPRECATED AND DEFUNCT</h4>
+
+
+<ul>
+<li> <p><code>data()</code> no longer handles zipped data from
+long-defunct (since <span class="rlang"><b>R</b></span> 2.13.0) <span class="option">--use-zip-data</span> installations.
+</p>
+</li>
+<li><p> The legacy graphics devices <code>pictex()</code> and
+<code>xfig()</code> are now deprecated.  They do not support recent
+graphics enhancements and their font-handling is rudimentary. The
+intention is to retain them for historical interest as long as
+they remain somewhat functional.
+</p>
+</li></ul>
+
+
+
+
+<h4>BUG FIXES</h4>
+
+
+<ul>
+<li><p> The methods package is more robust to not being attached to
+the search path. More work needs to be done.
+</p>
+</li>
+<li> <p><code>pairwise.t.test()</code> misbehaved when subgroups had 0 DF
+for variance, even with <code>pool.sd=TRUE</code> <a href="https://bugs.R-project.org/show_bug.cgi?id=18594">PR#18594</a> (Jack Berry).
+</p>
+</li>
+<li><p> Probability distribution functions <code>[dpq]&lt;distrib&gt;(x, *)</code>,
+but also <code>bessel[IKJY](x, .)</code> are now consistently preserving
+<code>attributes(x)</code> when <code>length(x) == 0</code>, e.g., for a
+<code class="reqn">2 \times 0</code> matrix, thanks to Karolis Koncevičius'
+report <a href="https://bugs.R-project.org/show_bug.cgi?id=18509">PR#18509</a>.
+</p>
+</li>
+<li><p> Group &ldquo;Summary&rdquo; computations such as
+<code>sum(1:3, 4, na.rm = 5, NA, 7, na.rm = LL)</code> now give an error
+instead of either <code>17</code> or <code>NN</code> for <code>LL</code> true or false,
+as proposed by Ivan Krylov on the R-devel mailing list.  (This
+also means it is now an error to specify <code>na.rm</code> more than once.)
+</p>
+</li>
+<li> <p><code>as.complex(x)</code> now returns <code>complex(real=x,
+      imaginary=0)</code> for <em>all</em> numerical and logical <code>x</code>, notably
+also for <code>NA</code> or <code>NA_integer_</code>.
+</p>
+</li>
+<li><p> Directories are now omitted by
+<code>file.copy(,recursive = FALSE)</code> and in <code>file.append()</code>
+(<a href="https://bugs.R-project.org/show_bug.cgi?id=17337">PR#17337</a>).
+</p>
+</li>
+<li> <p><code>gsub()</code> and <code>sub()</code> are now more robust to integer
+overflow when reporting errors caused by too large input strings
+(<a href="https://bugs.R-project.org/show_bug.cgi?id=18346">PR#18346</a>).
+</p>
+</li>
+<li><p> Top-level handlers are now more robust to attempts to remove a
+handler whilst handlers are running (<a href="https://bugs.R-project.org/show_bug.cgi?id=18508">PR#18508</a>).
+</p>
+</li>
+<li><p> The handling of <code>Alt+F4</code> in dialogs created on Windows using
+GraphApp has been fixed (<a href="https://bugs.R-project.org/show_bug.cgi?id=13870">PR#13870</a>).
+</p>
+</li>
+<li> <p><code>density()</code> more consistently computes grid values for the
+FFT-based convolution, following Robert Schlicht's analysis and
+proposal in <a href="https://bugs.R-project.org/show_bug.cgi?id=18337">PR#18337</a>, correcting density values typically by a
+factor of about 0.999.  Optional <code>old.coords=TRUE</code> provides
+back compatibility.
+</p>
+</li>
+<li> <p><code>palette.colors()</code> gains a <code>name</code> argument that
+defaults to <code>FALSE</code> controlling whether the vector of colours
+that is returned has names (where possible).  <a href="https://bugs.R-project.org/show_bug.cgi?id=18529">PR#18529</a>.
+</p>
+</li>
+<li> <p><code>tools::xgettext()</code> no longer extracts the
+(non-translatable) class names from <code>warningCondition</code> and
+<code>errorCondition</code> calls.
+</p>
+</li>
+<li> <p><code>S3method(&lt;gen&gt;, &lt;class&gt;, &lt;func&gt;)</code> in the &lsquo;<span class="file">NAMESPACE</span>&rsquo;
+file now works (again) when <code>&lt;func&gt;</code> is visible from the
+namespace, e.g., imported, or in base.
+</p>
+</li>
+<li> <p><code>getParseData(f)</code> now also works for a function defined
+in the first of several &lsquo;<span class="file">&lt;pkg&gt;/R/*.R</span>&rsquo; source files, thanks to
+Kirill Müller's report and Duncan Murdoch's patch in <a href="https://bugs.R-project.org/show_bug.cgi?id=16756">PR#16756</a>.
+</p>
+</li>
+<li><p> Rd <code style="white-space: pre;">&#8288;\Sexpr&#8288;</code> macros with nested <code style="white-space: pre;">&#8288;#ifdef&#8288;</code>
+conditionals were not processed.
+</p>
+</li>
+<li><p> A non-blocking connection with non-default encoding such as
+a socket, now correctly returns from <code>readLines()</code> after new
+data has arrived also when its <code>EOF</code> had been reached
+previously.  Thanks to Peter Meilstrup's report on R-devel and
+Ivan Krylov's report and patch proposal in <a href="https://bugs.R-project.org/show_bug.cgi?id=18555">PR#18555</a>.
+</p>
+</li>
+<li> <p><code>tools::checkRdContents()</code> failed to detect empty
+argument descriptions when they spanned multiple lines,
+including those generated by <code>prompt()</code>.
+These cases are now noted by <code>R CMD check</code>.
+</p>
+</li>
+<li><p> Plain-text help no longer outputs spurious colons in the
+arguments list (for multi-line <code style="white-space: pre;">&#8288;\item&#8288;</code> labels in the Rd source).
+</p>
+</li>
+<li> <p><code>kappa()</code> and <code>rcond()</code> work correctly in more cases;
+<code>kappa(., norm = "2")</code> now warns that it computes the 1-norm with
+(default) <code>exact = FALSE</code>; prompted by Mikael Jagan's quite
+comprehensive <a href="https://bugs.R-project.org/show_bug.cgi?id=18543">PR#18543</a>.
+</p>
+</li>
+<li><p> Rd skeletons generated by <code>prompt()</code> or
+<code>promptData()</code> now use a dummy title (so <code>R CMD
+      build</code> works).  <code>tools::checkRdContents()</code> has been updated
+to detect such template leftovers, including from
+<code>promptPackage()</code>.
+</p>
+</li>
+<li><p> When S4 method dispatch fails because no method was found, the
+error message now includes the signature argument names; thanks to
+Michael Chirico's proposal on R-devel.
+</p>
+</li>
+<li> <p><code>withAutoprint({ .. })</code> now preserves <code>srcref</code>s
+previously lost, thanks to Andrew Simmons' report plus fix in
+<a href="https://bugs.R-project.org/show_bug.cgi?id=18572">PR#18572</a>.
+</p>
+</li>
+<li> <p><code>transform.data.frame()</code> no longer adjusts names;
+in particular, untransformed variables are kept as-is,
+including those with syntactically invalid names (<a href="https://bugs.R-project.org/show_bug.cgi?id=17890">PR#17890</a>).
+</p>
+</li>
+<li><p> The <code>keep.source</code> option for Rd <code style="white-space: pre;">&#8288;\Sexpr&#8288;</code> blocks is
+no longer ignored.
+</p>
+</li>
+<li><p> The <code>formula</code> methods for <code>t.test()</code> and
+<code>wilcox.test()</code> now catch when <code>paired</code> is passed,
+addressing <a href="https://bugs.R-project.org/show_bug.cgi?id=14359">PR#14359</a>; use <code>Pair(x1, x2) ~ 1</code> for a paired test.
+</p>
+</li>
+<li><p> The level reported in the browser prompt was often too
+large. It now shows the number of browser contexts on the stack.
+</p>
+</li>
+<li><p> For <code>cbind()</code> and <code>rbind()</code>, the optional
+<code>deparse.level</code> argument is now properly passed to methods,
+thanks to Mikael Jagan's <a href="https://bugs.R-project.org/show_bug.cgi?id=18579">PR#18579</a> and comments there.
+</p>
+</li>
+<li><p> Some error and warning messages for large (&lsquo;long
+vector&rsquo;) <code>matrix(v, nr, nc)</code> and <code>dim(m) &lt;- d</code> are now
+correct about sizes, using <code>long long</code> formatting, fixing
+<a href="https://bugs.R-project.org/show_bug.cgi?id=18612">PR#18612</a> (and more) reported by Mikael Jagan.
+</p>
+</li>
+<li> <p><code>readChar(useBytes = TRUE)</code> now terminates strings even when
+the underlying connection uses extra spacea in the input buffer.  This
+fixes problems with extra garbage seen with <code>gzip</code>
+connections, <a href="https://bugs.R-project.org/show_bug.cgi?id=18605">PR#18605</a>.
+</p>
+</li>
+<li><p> Named capture in PCRE regular expressions now works also with
+more than 127 named groups (<a href="https://bugs.R-project.org/show_bug.cgi?id=18588">PR#18588</a>).
+</p>
+</li>
+<li><p> Datetime functions are now robust against long jumps when
+dealing with internal time zone changes.  This avoids confusing
+warnings about an invalid time zone, previously triggered by turning
+warnings into errors or handling them via <code>tryCatch</code> (<a href="https://bugs.R-project.org/show_bug.cgi?id=17966">PR#17966</a>,
+<a href="https://bugs.R-project.org/show_bug.cgi?id=17780">PR#17780</a>).
+</p>
+</li>
+<li><p> Datetime functions now restore even an empty <span class="env">TZ</span>
+environment variable after internal time zone changes (<a href="https://bugs.R-project.org/show_bug.cgi?id=17724">PR#17724</a>).
+This makes results of datetime functions with this (typically
+unintentional) setting more predictable.
+</p>
+</li>
+<li> <p><code>drop.terms(*)</code> now drops response as by default,
+<code>keep.response = FALSE</code>, fixing <a href="https://bugs.R-project.org/show_bug.cgi?id=18564">PR#18564</a> thanks to Mikael Jagan.
+</p>
+</li>
+<li> <p><code>dummy.coef(.)</code> now also works for <code>lm()</code>-models with
+<code>character</code> categorical predictor variables rather than
+<code>factor</code> ones, fixing <a href="https://bugs.R-project.org/show_bug.cgi?id=18635">PR#18635</a> reported by Jinsong Zhao.
+</p>
+</li>
+<li> <p><code>formals(f) &lt;- formals(f)</code> now also works for a function
+w/o arguments and atomic <em>constant</em> <code>body(f)</code>.
+</p>
+</li>
+<li><p> Correct <code>as.function(&lt;invalid list&gt;, .)</code>'s error message.

+<h3><img src="../help/figures/../../html/Rlogo.svg" class="toplogo" alt="[R logo]" /> CHANGES IN R 4.3.2 patched</h3>
+
+
+
+<h4>NEW FEATURES</h4>
+
+
+<ul>
+<li> <p><code>iconv()</code> now fixes up variant encoding names such as
+<code>"utf8"</code> case-insensitively.
+</p>
+</li></ul>
+
+
+
+
+<h4>DEPRECATED AND DEFUNCT</h4>
+
+
+<ul>
+<li><p> The legacy <code>encoding = "MacRoman"</code> is deprecated in
+<code>pdf()</code> and <code>postscript()</code>: support was incomplete in
+earlier versions of <span class="rlang"><b>R</b></span>.
+</p>
+</li></ul>
+
+
+
+
+<h4>BUG FIXES</h4>
+
+
+<ul>
+<li><p> Arguments are now properly forwarded to methods on S4 generics
+with ... in the middle of their formal arguments. This was
+broken for the case when a method introduced an argument but did
+not include ... in its own formals. Thanks to Hervé Pagès for
+the report <a href="https://bugs.R-project.org/show_bug.cgi?id=18538">PR#18538</a>.
+</p>
+</li>
+<li><p> Some invalid <code>file</code> arguments to <code>pictex()</code>,
+<code>postscript()</code> and <code>xfig()</code> opened a file called
+&lsquo;<span class="samp">&#8288;NA&#8288;</span>&rsquo; rather than throw an error.  These included
+<code>postscript(NULL)</code> (which some people expected to work like
+<code>pdf(NULL)</code>).
+</p>
+</li>
+<li><p> Passing <code>filename = NA</code> to <code>svg()</code>, <code>cairo_pdf()</code>,
+<code>cairo_ps()</code> or the Cairo-based bitmap devices opened a file
+called &lsquo;<span class="samp">&#8288;NA&#8288;</span>&rsquo;: it now throws an error.
+</p>
+</li>
+<li> <p><code>quartz(file = NA)</code> opened a file called &lsquo;<span class="samp">&#8288;NA&#8288;</span>&rsquo;, including
+when used as a Quartz-based bitmap device.  It now gives an error.
+</p>
+</li>
+<li> <p><code>rank(&lt;long vector&gt;)</code> now works, fixing <a href="https://bugs.R-project.org/show_bug.cgi?id=18617">PR#18617</a>, thanks to
+Ilia Kats.
+</p>
+</li>
+<li> <p><code>seq.int()</code> did not adequately check its
+<code>length.out</code> argument.
+</p>
+</li>
+<li> <p><code>match(&lt;POSIXct&gt;, .)</code> is correct again for differing time
+zones, ditto for <code>"POSIXlt"</code>, fixing <a href="https://bugs.R-project.org/show_bug.cgi?id=18618">PR#18618</a> reported by
+Bastian Klein.
+</p>
+</li>
+<li> <p><code>drop.terms(*, dropx = &lt;0-length&gt;)</code> now works, fixing
+<a href="https://bugs.R-project.org/show_bug.cgi?id=18563">PR#18563</a> as proposed by Mikael Jagan.
+</p>
+</li>
+<li> <p><code>drop.terms(*)</code> keeps <code> + offset(.)</code> terms when it should,
+<a href="https://bugs.R-project.org/show_bug.cgi?id=18565">PR#18565</a>, and <code>drop.terms()</code> no longer makes up a response,
+<a href="https://bugs.R-project.org/show_bug.cgi?id=18566">PR#18566</a>, fixing both bugs thanks to Mikael Jagan.
+</p>
+</li>
+<li> <p><code>getS3method("t", "test")</code> no longer finds the
+<code>t.test()</code> function, fixing <a href="https://bugs.R-project.org/show_bug.cgi?id=18627">PR#18627</a>.
+</p>
+</li>
+<li> <p><code>pdf()</code> and <code>postscript()</code> support for the documented
+Adobe encodings <code>"Greek"</code> and <code>"Cyrilllic"</code> was missing
+(although the corresponding Windows' codepages could be used).
+</p>
+</li>
+<li><p> Computations of glyph metric information for <code>pdf()</code>
+and <code>postscript()</code> did not take into account that
+transliteration could replace one character by two or more (only
+seen on macOS 14) and typically warned that the information was
+not known.
+</p>
+</li>
+<li> <p><code>list.files()</code> on Windows now returns also files with names
+longer that 260 bytes (the Windows limit is 260 characters).
+Previously, some file names particularly with &lsquo;East Asian&rsquo;
+characters were omitted.
+</p>
+</li></ul>
