The build system rolled up R-3.6.2.tar.gz (codename "Dark and Stormy Night") this morning.
The list below details the changes in this release.
You can get the source code from
or wait for it to be mirrored at a CRAN site nearer to you.
Binaries for various platforms will appear in due course.

CHANGES IN R 3.6.2:
* runmed(x, *) gains a new option na.action determining _how_ to
handle NaN or NA in x.
* dotchart() gains new options ann, xaxt, frame.plot and log.
INSTALLATION on a UNIX-ALIKE:
* Detection of the C stack direction has been moved from run-time
to configure: this is safer with LTO builds and allows the
detection to be overridden - see file config.site.
* Source-code changes enable installation on platforms using gcc
-fno-common (the expected default for gcc 10.x).
* installTrChar (which is nowadays is wrapped by installChar) is
defined in Rinternals.h. (Neither are part of the API.)
* Header Rconfig.h contains the value of FC_LEN_T deduced at
installation which is used by the prototypes in headers
R_ext/BLAS.h and R_ext/Lapack.h but to avoid extensive breakage
this is only exposed when USE_FC_LEN_T is defined.
If a package's C/C++ calls to BLAS/LAPACK allow for the 'hidden'
arguments used by most Fortran compilers to pass the lengths of
Fortran character arguments, define USE_FC_LEN_T and include
Rconfig.h (possibly _via_ R.h) before including R_ext/BLAS.h or
* A package with Fortran source code and perhaps C (but not C++)
sources can request for its shared object/DLL to be linked by the
Fortran compiler by including a line USE_FC_TO_LINK= in
src/Makevars[.win] and using $(SHLIB_OPENMP_FFLAGS) as part of
The known reason for doing so is a package which uses Fortran
(only) OpenMP on a platform where the Fortran OpenMP runtime is
incompatible with the C one (e.g. gfortran 9.x with clang).
* R CMD check has a new option to mitigate checks leaving
files/directories in /tmp. See the 'R Internals' manual - this
is part of --as-cran.
* The default standard for C++ in package installation is C++11 (as
it has been on other platforms where available since R 3.6.0: the
default toolchain on Windows was defaulting to C++98).
DEPRECATED AND DEFUNCT:
* Support for specifying C++98 in package installation is
* Support in R CMD config for F77, FCPIFCPLAGS, CPP, CXXCPP and
CXX98 and similar is deprecated. (CPP is found from the system
make and may well not be set.)
Use $CC -E and $CXX -E instead of CPP and CXXCPP.
* runmed(x, *) when x contains missing values now works
consistently for both algorithm="Stuetzle" and "Turlach", and no
longer segfaults for "Turlach", as reported by Hilmar Berger.
* apply(diag(3), 2:3, mean) now gives a helpful error message.
* dgamma(x, shape, log=TRUE) now longer overflows to Inf for shape
< 1 and very small x, fixing PR#17577, reported by Jonathan
* Buffer overflow in building error messages fixed. Reported by
* options(str = .) is correctly initialized at package utils load
time, now. A consequence is that str() in scripts now is more
consistent to interactive use, e.g., when displaying function(**)
* as.numeric(<call>) now gives correct error message.
* Printing ls.str() no longer wrongly shows "<missing>" in rare
* Auto-printing S4 objects no longer duplicates the object, for
faster speed and reduced memory consumption. Reported by Aaron
* pchisq(<LRG>, <LRG>, ncp=100) no longer takes practically forever
in some cases. Hence ditto for corresponding qchisq() calls.
* x %% L for finite x no longer returns NaN when L is infinite, nor
suffers from cancellation for large finite L, thanks to Long Qu's
Analogously, x %/% L and L %/% x suffer less from cancellation
and return values corresponding to limits for large L.
* grepl(NA, *) now returns logical as documented.
* options(warn=1e11) is an error now, instead of later leading to C
stack overflow because of infinite recursion.
* R_tryCatch no longer transfers control for all conditions.
Reported and patch provided by Lionel Henry in PR#17617.
* format(object.size(.), digits=NULL) now works, fixing PR#17628
reported by Jonathan Carroll.
* get_all_vars(f, d) now also works for cases, e.g. where d
contains a matrix. Reported by Simon Wood in 2009 and patch
provided by Ben Bolker in PR#13624.
Additionally, it now also works when some variables are data
frames, fixing PR#14905, reported by Patrick Breheny.
* barplot() could get spacings wrong if there were exactly two bars
PR#15522. Patch by Michael Chirico.
* power.t.test() works in more cases when returning values of n
smaller than 2.
* dotchart(*, pch=., groups=.) now works better. Reported by
Robert and confirmed by Nic Rochette in PR#16953.
* canCoerce(obj, cl) no longer assumes length(class(obj)) == 1.
* plot.formula(*, subset = *) now also works in a boundary case
reported by Robert Schlicht (TU Dresden).
* readBin() and writeBin() of a rawConnection() now also work in
large cases, thanks to a report and proposal by Taeke Harkema in
