Lots of good hi-rez shots of some of the new wings here:

The most obvious new wing is a higher downforce version of the cascade-less FW used at Spa and Monza. It appears to be the same basic design, but with a larger adjustable flap, and slightly different endplate. Ferrari seems to be following Mercedes here, who switched to a cascade-less design earlier in the season.
They tested this new front wing with what appeared to be the 'max downforce Monaco' rear wing, which doesn't have the v cuts in the trailing edge, and has the older style endplates. So my guess is they will run this combination in Singapore, where they need max downforce and top speed is not much of an issue.
Here is a good shot showing what appears to be two copies of the new cascade-less wing. Not sure what is different between them:
