A general description is here.
matplot(), matlines() and matpoints() now also obey a 'lend' argument, determining line end styles. (Wish of PR#13619).
parse_Rd() would mishandle closing braces when they occurred at the start of a line within an R string in an Rd file. (Reported by Alex Couture-Beil.)
memory.limit(size) gave a spurious error message.
memory.size() and memory.limits() now return rounded values.
