I *think* (have not yet tried it, though) that the latest LinkedIn RC will work with Spring Social Core/Web 1.1.0.M1. If not, then you may want to hold off on 1.1.0.M1 until I get a new LinkedIn RC pushed.
I was hoping to push a new LinkedIn RC along with 1.1.0.M1 yesterday, but ran out of time to get it prepared. So, I decided to hold off on a new RC until the 1.1.0.M2 timeframe (around Dec 19, give or take). If, however, you have a pressing need to use Spring Social LinkedIn with Spring Social 1.1.0.M1 and you can prove that the existing RC won't work with 1.1.0.M1, I can try to set aside some time in the next day or two to cut a new RC. Know, however, that my time this week is limited and starting Friday I go off-the-grid for a long overdue family vacation. So I may not get around to cutting that release until I return (on or around Dec 6).
