When I run v2.7.0, PatternLabHead and PatternLabFoot are missing on the "View All" page for whatever is the first pattern type for which such a a view exists.
So, in the demo install, because 00-atoms is first, and has sub-patterns,
http://localhost:8080/patterns/00-atoms/index.html
is missing the lines that pull in the styleguide CSS, script loader, etc.
This appears to be due to July 12 changes to Builder.php
("processing the header and footer with the patternLoader").
Running with the June 28 commit of Builder.php solved the issue for me.
