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.

2017/04/23 ver 3.4.0

CHANGES IN R 3.4.0
SIGNIFICANT USER-VISIBLE CHANGES
(Unix-alike)
The default methods for download.file() and url()
now choose "libcurl" except for file://
URLs. There will be small changes in the format and wording of
messages, including in rare cases if an issue is a warning or an
error. For example, when HTTP re-direction occurs, some messages
refer to the final URL rather than the specified one.
Those who use proxies should check that their settings are
compatible (see ?download.file: the most commonly used
forms work for both "internal" and "libcurl").
table() has been amended to be more internally
consistent and become back compatible to R <= 2.7.2
again. Consequently, table(1:2, exclude = NULL) no longer
contains a zero count for <NA>, but useNA = "always"
continues to do so.
summary.default() no longer rounds, but its print
method does resulting in less extraneous rounding, notably of

2017/03/07 ver 3.3.3

CHANGES IN R 3.3.3
NEW FEATURES
Changes when redirection of a http:// URL to a
https:// URL is encountered:
The internal methods of download.file() and
url() now report that they cannot follow this (rather
than failing silently).
(Unix-alike) download.file(method = "auto") (the
default) re-tries with method = "libcurl".
(Unix-alike) url(method = "default") with an
explicit open argument re-tries with
method = "libcurl". This covers many of the usages,
e.g. readLines() with a URL argument.
INSTALLATION on a UNIX-ALIKE
The configure check for the zlib version is
now robust to versions longer than 5 characters, including
1.2.11.

2016/11/07 ver 3.3.2

CHANGES IN R 3.3.2
NEW FEATURES
extSoftVersion() now reports the version (if any) of
the readline library in use.
The version of LAPACK included in the sources has been
updated to 3.6.1, a bug-fix release including a speedup for the
non-symmetric case of eigen().
Use options(deparse.max.lines=) to limit the number
of lines recorded in .Traceback and other deparsing
activities.
format(<AsIs>) looks more regular, also for
non-character atomic matrices.
abbreviate() gains an option named = TRUE.
The online documentation for package methods is
extensively rewritten. The goals are to simplify
documentation for basic use, to note old features not
recommended and to correct out-of-date information.
Calls to setMethod() no longer print a message when
creating a generic function in those cases where that is

2016/06/22 ver 3.3.1

CHANGES IN R 3.3.1
BUG FIXES
R CMD INSTALL and hence install.packages()
gave an internal error installing a package called
description from a tarball on a case-insensitive file system.
match(x, t) (and hence x %in% t) failed
when x was of length one, and either character and x
and t only differed in their Encoding or when
x and t where complex with NAs or NaNs.
(PR#16885.)
unloadNamespace(ns) also works again when ns is a
‘namespace’, as from getNamespace().
rgamma(1,Inf) or rgamma(1, 0,0) no longer give
NaN but the correct limit.
length(baseenv()) is correct now.
pretty(d, ..) for date-time d rarely failed
when "halfmonth" time steps were tried (PR#16923) and
on ‘inaccurate’ platforms such as 32-bit windows or
a configuration with --disable-long-double; see comment

2016/05/05 ver 3.3.0

CHANGES IN R 3.3.0
SIGNIFICANT USER-VISIBLE CHANGES
nchar(x, *)'s argument keepNA governing how
the result for NAs in x is determined, gets a new
default keepNA = NA which returns NA where
x is NA, except for type = "width" which still
returns 2, the formatting / printing width of NA.
All builds have support for https: URLs in the
default methods for download.file(), url() and code
making use of them.
Unfortunately that cannot guarantee that any particular
https: URL can be accessed. For example, server and client
have to successfully negotiate a cryptographic protocol (TLS/SSL,
...) and the server's identity has to be verifiable via
the available certificates. Different access methods may allow
different protocols or use private certificate bundles: we
encountered a https: CRAN mirror which could be accessed by
one browser but not by another nor by download.file() on
the same Linux machine.

2016/04/16 ver 3.2.5

CHANGES IN R 3.2.5
BUG FIXES
format.POSIXlt() behaved incorrectly in R 3.2.4.
E.g. the output of
format(as.POSIXlt(paste0(1940:2000,"-01-01"), tz = "CET"),
usetz = TRUE) ended in two "CEST" time formats.
A typo in the Makefile for ‘src/extra/xz’ prevented
builds of ‘liblzma.a’. (Notice that this will become
unbundled in 3.3.0.)

2016/03/15 ver 3.2.4

CHANGES IN R 3.2.4
NEW FEATURES
install.packages() and related functions now give a
more informative warning when an attempt is made to install a base
package.
summary(x) now prints with less rounding when
x contains infinite values. (Request of PR#16620.)
provideDimnames() gets an optional unique argument.
shQuote() gains type = "cmd2" for quoting
in cmd.exe in Windows. (Response to PR#16636.)
The data.frame method of rbind() gains an
optional argument stringsAsFactors (instead of only
depending on getOption("stringsAsFactors")).
smooth(x, *) now also works for long vectors.
tools::texi2dvi() has a workaround for problems with
the texi2dvi script supplied by texinfo 6.1.
It extracts more error messages from the LaTeX logs when in
emulation mode.
