This is now expected behavior, see NEWS.  If you want the old
behavior, rebind mouse-2, or use one of the suggestions in NEWS.

    *** mouse-2 is now bound to `mouse-yank-primary'.
    This pastes from the primary selection, ignoring the kill-ring.
    Previously, mouse-2 was bound to `mouse-yank-at-click'.

    *** To return to the previous behavior, do the following:
    **** Change `select-active-regions' to nil.
    **** Change `mouse-drag-copy-region' to t.
    **** Change `x-select-enable-primary' to t (on X only).
    **** Change `x-select-enable-clipboard' to nil.
    **** Bind `mouse-yank-at-click' to mouse-2.

Btw, you will only get the stuff in kill-ring if the kill-ring is
non-empty.  If it is empty, you still get the clipboard.

I'm closing this bug report.
