current Over-Optimization Update
Looks to me like there's 2 main focuses'
1. Penalise sites with unnatural back link patterns.
2. promote sites that avoid keyword stuffing by heavy use of synonyms.
I'm seeing a couple of sites that are stuffed with semantically close and synonym words ranking well for the target term. They are, kind of, over optimised for synonyms.
