A general description is here.
‘isoreg(numeric(0))’ no longer returns unallocated component ‘yc’, fixing PR#19224 thanks to Kevin Ushey.
‘ksmooth(x,y, x.points=NULL)’ now returns an empty (x,y) pair instead of crashing R, fixing PR#19153.
Additionally, also by Adam Berkeš, ‘x <- rep(999,0); ksmooth(x, x, x.points = 1)’ no longer writes out of bounds, fixing PR#19171. Ditto for ‘ksmooth(x, x, n.points = 0)’, PR#19219.
