This blog is updated daily.
A general description is here.
‘sum(x)’ and ‘sum(x1,x2,..,x<N>)’ with many or long logical and integer vectors no longer overflows (and returns ‘NA’ with a warning), but returns ‘double’ numbers now in such cases.
‘methods:::bind_activation()’ is defunct now; it typically has been unneeded for years.
the undocumented "hidden" ‘.__H__.cbind’ and ‘.__H__.rbind’ are deprecated, correspondingly.
