This blog is updated daily.
A general description is here.
The 'factor' method of format() now preserves names, dims and dimnames in the same way as for character and numeric inputs. (PR#11512)
plot(<table>) now uses a sensible default main title.
qf() no longer gives NaN when one of df1 and df2 is large and the other is infinite (including if both are infinite); it is more accurate e.g. for qf(1e-18, 2,4).
qbeta(-1e10, 50, 40, log.p=TRUE) no longer hangs.
