McLaren, Lotus and Toro Rosso have all introduced splitters with fences added to the upper, outboard leading edge.  McLaren (above) introduced their fences (marked in yellow) as far back as Malaysia, whilst Toro Rosso updated theirs to three piece elements in Spain and Lotus introduced singular fences in Monaco.
