A general description is here.
‘which.min(x)’ and ‘which.max(x)’ may be much faster for logical and integer ‘x’ and now also work for long vectors.
Help for ‘which.min’ is now more precise about behavior with logical arguments. (PR#16532)
‘nchar(x, "w")’ returned -1 for characters it did not know about (e.g. zero-width spaces): it now assumes 1. It now knows about most zero-width characters and a few more double-width characters.
