The internal method of download.file() can now handle files larger than 2GB on 32-bit builds which support such files (tested on 32-bit R running on 64-bit Windows).
kruskal.test() warns on more types of suspicious input.
The as.dendrogram() method for "hclust" objects gains a check argument protecting against memory explosion for invalid inputs.
capabilities() has a new item long.double which indicates if the build uses a long double type which is longer than double.
nlm() no longer modifies the callback argument in place (a new vector is allocated for each invocation, which mimics the implicit duplication that occurred in R < 3.1.0); note that this is a change from the previously documented behavior. ()
icuSetCollate() now accepts locale = "ASCII" which uses the basic C function strcmp and so collates strings byte-by-byte in numerical order.
sessionInfo() tries to report the OS version in use (not just that compiled under, and including details of Linux distributions).
model.frame() (used by lm() and many other modelling functions) now warns when it drops contrasts from factors. (Wish of )
install.packages() and friends now accept the value type = "binary" as a synonym for the native binary type on the platform (if it has one).
Single source or binary files can be supplied for install.packages(type = "both") and the appropriate type and repos = NULL will be inferred.
New function pcre_config() to report on some of the configuration options of the version of PCRE in use. In particular, this reports if regular expressions using \p{xx} are supported.
(Windows.) download.file(cacheOK = FALSE) is now supported when ‘internet2.dll’ is used.
browseURL() has been updated to work with Firefox 36.0 which has dropped support for the -remote interface.
