CHANGES IN R 3.6.3
NEW FEATURES
The included LAPACK has been updated to version 3.9.0 (for
the included routines, just bug fixes).
BUG FIXES
Fixed a C level integer overflow in rhyper(); reported
by Benjamin Tyner in PR#17694.
Uses of url(gzcon(.)) needing to extend buffer size
have failed (with HTTP/2 servers), reported by G叩bor Cs叩rdi.
predict(loess(..), se=TRUE) now errors out (instead of
seg.faulting etc) for large sample sizes, thanks to a report and
patch by Benjamin Tyner in PR#17121.
tools:assertCondition(., "error") and hence
assertError() no longer return errors twice (invisibly).
update(form, new) in the case of a long new
formula sometimes wrongly eliminated the intercept from form,
or (more rarely) added a garbage term (or seg.faulted !); the fix
happened by simplifying the C-level logic of terms.formula().
Reported by Mathias Amb端hl in PR#16326.

2019/12/15 ver 3.6.2

CHANGES IN R 3.6.2
NEW FEATURES
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).
C-LEVEL FACILITIES
installTrChar (which is nowadays is wrapped by
installChar) is defined in ‘Rinternals.h’. (Neither
are part of the API.)
PACKAGE INSTALLATION

2019/07/07 ver 3.6.1

CHANGES IN R 3.6.1
INSTALLATION on a UNIX-ALIKE
The default detection of the shell variable libNN is
overridden for derivatives of Debian Linux, some of which have
started to have a ‘/usr/lib64’ directory.
(E.g. Ubuntu 19.04.) As before, it can be specified in
‘config.site’.
UTILITIES
R CMD config knows the values of AR and
RANLIB, often set for LTO builds.
DEPRECATED AND DEFUNCT
The use of a character vector with .Fortran() is
formally deprecated and gives a non-portability warning. (It has
long been strongly discouraged in ‘Writing R Extensions’.)
BUG FIXES
On Windows, GUI package installation via menuInstallPkgs()
works again, thanks to Len Weil's and Duncan Murdoch's PR#17556.
R CMD check on data() fixing PR#17558
thanks to Duncan Murdoch.

2019/04/28 ver 3.6.0

CHANGES IN R 3.6.0
SIGNIFICANT USER-VISIBLE CHANGES
Serialization format version 3 becomes the default for
serialization and saving of the workspace (save(),
serialize(), saveRDS(), compiler::cmpfile()).
Serialized data in format 3 cannot be read by versions of R prior
to version 3.5.0. Serialization format version 2 is still
supported and can be selected by version = 2 in the
save/serialization functions. The default can be changed back for
the whole R session by setting environment variables
R_DEFAULT_SAVE_VERSION and R_DEFAULT_SERIALIZE_VERSION
to 2. For maximal back-compatibility, files
‘vignette.rds’ and ‘partial.rdb’ generated by R
CMD build are in serialization format version 2, and resave by
default produces files in serialization format version 2 (unless
the original is already in format version 3).
The default method for generating from a discrete uniform
distribution (used in sample(), for instance) has been
changed. This addresses the fact, pointed out by Ottoboni and

2019/03/12 ver 3.5.3

CHANGES IN R 3.5.3
INSTALLATION on a UNIX-ALIKE
Detection of flags for C++98/11/14/17 has been improved: in
particular if CXX??STD is set, it is tried first with no
additional flags.
PACKAGE INSTALLATION
New macro F_VISIBILITY as an alternative to
F77_VISIBILITY. This will become the preferred form in
R 3.6.0.
BUG FIXES
writeLines(readLines(fnam), fnam) now works as expected,
thanks to Peter Meissner's PR#17528.
setClassUnion() no longer warns, but uses message()
for now, when encountering “non local” subclasses of class members.
stopifnot(exprs = T) no longer fails.

2018/12/21 ver 3.5.2

CHANGES IN R 3.5.2
PACKAGE INSTALLATION
New macro CXX_VISIBILITY analogous to
C_VISIBILITY (which several packages have been misusing for
C++ code) for the default C++ compiler (but not necessarily one used
for non-default C++ dialects like C++14).
TESTING
The random number generator tests in
‘tests/p-r-random-tests.R’ no longer fail occasionally as
they now randomly sample from “certified” random seeds.
BUG FIXES
The "glm" method of drop1() miscalculated the
score test (test="Rao") when the model contained an offset.
Linear multiple empty models such as lm(y ~ 0)
now have a correctly dimensioned empty coefficient matrix;
reported by Brett Presnell.
vcov(<empty mlm>) and hence confint() now
work (via a consistency change in summary.lm()).
confint(<multiple lm()>) now works correctly;

2018/04/24 ver 3.5.0

CHANGES IN R 3.5.0
SIGNIFICANT USER-VISIBLE CHANGES
All packages are by default byte-compiled on installation.
This makes the installed packages larger (usually marginally so)
and may affect the format of messages and tracebacks (which often
exclude .Call and similar).
NEW FEATURES
factor() now uses order() to sort its levels,
rather than sort.list(). This allows factor() to
support custom vector-like objects if methods for the appropriate
generics are defined. It has the side effect of making
factor() succeed on empty or length-one non-atomic
vector(-like) types (e.g., "list"), where it failed before.
diag() gets an optional names argument: this
may require updates to packages defining S4 methods for it.
chooseCRANmirror() and chooseBioCmirror() no
longer have a useHTTPS argument, not needed now all R
builds support https:// downloads.
New summary() method for warnings() with a

2018/03/17 ver 3.4.4

CHANGES IN R 3.4.4
NEW FEATURES
Sys.timezone() tries more heuristics on Unix-alikes and so
is more likely to succeed (especially on Linux). For the slowest
method, a warning is given recommending that TZ is set to
avoid the search.
The version of LAPACK included in the sources has been
updated to 3.8.0 (for the routines used by R, a very minor bug-fix
change).
parallel::detectCores(logical = FALSE) is ignored on
Linux systems, since the information is not available with
virtualized OSes.
INSTALLATION on a UNIX-ALIKE
configure will use pkg-config to find the
flags to link to jpeg if available (as it should be for the
recently-released jpeg-9c and libjpeg-turbo). (This
amends the code added in R 3.3.0 as the module name in
jpeg-9c is not what that tested for.)
DEPRECATED AND DEFUNCT
(省略されました)

2017/12/02 ver 3.4.3

CHANGES IN R 3.4.3
INSTALLATION on a UNIX-ALIKE
A workaround has been added for the changes in location of
time-zone files in macOS 10.13 ‘High Sierra’ and
again in 10.13.1, so the default time zone is deduced
correctly from the system setting when R is configured with
--with-internal-tzcode (the default on macOS).
R CMD javareconf has been updated to recognize the
use of a Java 9 SDK on macOS.
BUG FIXES
raw(0) & raw(0) and raw(0) | raw(0)
again return raw(0) (rather than logical(0)).
intToUtf8() converts integers corresponding to
surrogate code points to NA rather than invalid UTF-8, as
well as values larger than the current Unicode maximum of
0x10FFFF. (This aligns with the current RFC3629.)
Fix calling of methods on S4 generics that dispatch on
... when the call contains ....
Following Unicode ‘Corrigendum 9’, the UTF-8

2017/10/02 ver 3.4.2

CHANGES IN R 3.4.2
NEW FEATURES
Setting the LC_ALL category in Sys.setlocale()
invalidates any cached locale-specific day/month names and the
AM/PM indicator for strptime() (as setting LC_TIME
has since R 3.1.0).
The version of LAPACK included in the sources has been
updated to 3.7.1, a bug-fix release.
The default for tools::write_PACKAGES(rds_compress=)
has been changed to "xz" to match the compression used by
CRAN.
c() and unlist() are now more efficient in
constructing the names(.) of their return value, thanks to
a proposal by Suharto Anggono. (PR#17284)
UTILITIES
R CMD check checks for and R CMD build
corrects CRLF line endings in shell scripts configure
and cleanup (even on Windows).

2017/07/02 ver 3.4.1

CHANGES IN R 3.4.1
INSTALLATION on a UNIX-ALIKE
The deprecated support for PCRE versions older than 8.20
has been removed.
BUG FIXES
getParseData() gave incorrect column information when
code contained multi-byte characters. (PR#17254)
Asking for help using expressions like ?stats::cor()
did not work. (PR#17250)
readRDS(url(....)) now works.
R CMD Sweave again returns status = 0 on
successful completion.
Vignettes listed in ‘.Rbuildignore’ were not being
ignored properly. (PR#17246)
file.mtime() no longer returns NA on Windows when the
file or directory is being used by another process. This affected
installed.packages(), which is now protected against this.
R CMD INSTALL Windows .zip file obeys --lock
and --pkglock flags.
