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.

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.

Environmental variable _R_CHECK_TESTS_NLINES_ controls

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.
