I have not seen it mentioned yet, so I just wanted to report that SER pages have once again be de-cluttered. I personally never liked the full-page screenshots that Google were displaying and those have been removed. In addition, the cached page link looks similar to what Bing has been doing for quite a while (the down-pointing arrow).
To add, they also seemed to have become a little more conservative when display author photos.
I can't see anything else that has been changed yet.
Heh yea, G seems to be removing stuff that they once told us users loved, because the users loved them so much they didn't use them (related searches, instant previews - which probably interfered with the space devoted to product ads and Knowledge Graph)...
