This is the relevant part of the NEWS file
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).
INSTALLATION on a UNIX-ALIKE:
* The order of selection of OpenMP flags has been changed: Oracle
Developer Studio 12.5 accepts -fopenmp and -xopenmp but only the
latter enables OpenMP so it is now tried first.
BUG FIXES:
* within(List, rm(x1, x2)) works correctly again, including when
List[["x2"]] is NULL.
* regexec(pattern, text, *) now applies as.character(.) to its
first two arguments, as documented.
* write.table() and related functions, writeLines(), and perhaps
other functions writing text to connections did not signal errors
when the writes failed, e.g. due to a disk being full. Errors
will now be signalled if detected during the write, warnings if
detected when the connection is closed. (PR#17243)
* rt() assumed the ncp parameter was a scalar. (PR#17306)
* menu(choices) with more than 10 choices which easily fit into one
getOption("width")-line no longer erroneously repeats choices.
(PR#17312)
* length()<- on a pairlist succeeds. (<URL:
https://stat.ethz.ch/pipermail/r-devel/2017-July/074680.html>)
* Language objects such as quote(("\n")) or R functions are
correctly printed again, where R 3.4.1 accidentally duplicated
the backslashes.
* Construction of names() for very large objects in c() and
unlist() now works, thanks to Suharto Anggono's patch proposals
in PR#17292.
* Resource leaks (and similar) reported by Steve Grubb fixed.
(PR#17314, PR#17316, PR#17317, PR#17318, PR#17319, PR#17320)
* model.matrix(~1, mf) now gets the row names from mf also when
they differ from 1:nrow(mf), fixing PR#14992 thanks to the
suggestion by Sebastian Meyer.
* sigma(fm) now takes the correct denominator degrees of freedom
for a fitted model with NA coefficients. (PR#17313)
* hist(x, "FD") no longer "dies" with a somewhat cryptic
error
message when x has extreme outliers or IQR() zero: nclass.FD(x)
tries harder to find a robust bin width h in the latter case, and
hist.default(*, breaks) now checks and corrects a too large
breaks number. (PR#17274)
* callNextMethod() works for ... methods.
* qr.coef(qd, y) now has correct names also when qd is a complex QR
or stems from qr(*, LAPACK=TRUE).
* Setting options(device = *) to an invalid function no longer
segfaults when plotting is initiated. (PR#15883)
* encodeString(<very large string>) no longer segfaults.
(PR#15885)
* It is again possible to use configure --enable-maintainer-mode
without having installed notangle (it was required in R
3.4.[01]).
* S4 method dispatch on ... calls the method by name instead of
.Method (for consistency with default dispatch), and only
attempts to pass non-missing arguments from the generic.
* readRDS(textConnection(.)) works again. (PR#17325)
* (1:n)[-n] no longer segfaults for n <- 2.2e9 (on a platform with
enough RAM).
* x <- 1:2; tapply(x, list(x, x), function(x) "")[1,2] now
correctly returns NA. (PR#17333)
* Running of finalizers after explicit GC request moved from the R
interface do_gc to the C interface R_gc. This helps with
reclaiming inaccessible connections.
* help.search(topic) and ??topic matching topics in vignettes with
multiple file name extensions (e.g., *.md.rsp but not *.Rmd)
failed with an error when using options(help_type = "html").
* The X11 device no longer uses the Xlib backing store (PR#16497).
* array(character(), 1) now gives (a 1D array with) NA as has been
documented for a long time as in the other cases of zero-length
array initialization and also compatibly with matrix(character(),
*). As mentioned there, this also fixes PR#17333.
* splineDesign(.., derivs = 4) no longer segfaults.
* fisher.test(*, hybrid=TRUE) now (again) will use the hybrid
method when Cochran's conditions are met, fixing PR#16654.
