It’s been a very long time since this theme was updated … more from time constraints than anything else as the majority of the updates are as noted in its Trac ticket:

It looks like lots of changes, however most of the stuff is CSS related as well as code formatting. There are no visual issues and this Theme is now approved.
Review was based on Diff.
Trac Ticket #5740

This is the recent Changelog that also provides an overview of what was worked on as well … personally I think there was more than CSS and code formatting but I know the reviewer did a thorough job all the same; feel free to read for yourself.
