Look at the NEWS, which says, right at the top,
o The format for save/load has been changed. Workspaces and
objects saved in earlier versions can be loaded into this
version, but not conversely. Use save() or save.image() with
argument oldstyle=TRUE to save in the old format if you need to.
The new format is unknown to the older versions.
