Subaru still says 5w-30.
Though someone one time posted that they contacted Subaru and asked what weight oil was used as factory fill, they claim Subaru told them that 0w-20 is used as factory fill in their vehicles. If you look at UOAs done on Subaru factory fills, they always seem to be at a Xw-20 weight @ 100ºC, even when the factory fill was pulled VERY early.
Although it's not conclusive, I find it interesting that Subaru does not allow a Xw-20 oil, but it appears that this may be whats used as the factory fill.
Either way I stick with a Xw-30 in my Subaru
