This blog is updated daily.
A general description is here.
‘tar(*, tar = "internal")’ no longer creates out-of-spec tar files in the very rare case of user or group names longer than 32 bytes, fixing PR#17871 with thanks to Ivan Krylov.
When using the “internal” timezone datetime code, adding a fraction of a second no longer adds one second, fixing PR#16856 from a patch by Ivan Krylov.
New option ‘catch.script.errors’ provides a documented way to catch errors and continue in non-interactive use.
Some error and warning messages for large (‘long vector’) ‘matrix(v, nr, nc)’ and ‘dim(m) <- d’ are now correct about sizes, using ‘long long’ formatting, fixing PR#18612 (and more) reported by Mikael Jagan.
