Certainly some interesting changes. A website we rarely worked on just leap-frogged several other authorities in a genre I watch, with little to no work done on it (now position 3, up from 8-10)
I noticed that, congrats. This is a very competitive keyword phrase and two of the sites his site leap-frogged have been top 3 for years. Those two authority sites use similar SEO methods, which is to mainly buy SEO/traffic links from related sites so that might be a clue as to part of what has changed.
