A general description is here.
‘barplot()’ gets a formula method, thanks to a patch proposal by Arni Magnusson in PR#17521.
‘sum(x)’ and ‘sum(x1, x2, .., x<N>)’ with many or long logical or integer vectors no longer overflows (and returns ‘NA’ with a warning), but returns ‘double’ numbers in such cases.
On Unix-like platforms which support the ‘getline’ C library function, ‘system(*, intern = TRUE)’ no longer truncates (output) lines longer than 8192 characters, thanks to Karl Millar. (PR#16544)
New string utilities ‘startsWith(x, prefix)’ and ‘endsWith(x, suffix)’. Also provide speedups for some ‘grepl("^...", *)’ uses (related to proposals in PR#16490).
‘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.
