Comment (by pavelevap):

 Theme authors use `post__in` usually for getting Sticky posts with
 fallback to recently added posts. See example which stopped working in
 latest trunk:
 https://themes.trac.wordpress.org/browser/magazino/1.1.5/index.php#L13
 In 3.9.1 there is slider with 10 latest posts, but in current trunk there
 is no slider. There will be many related problems with themes, I guess...
