I saw two of the changes.
1) Photos: It using a floating lightbox style with a black background. Did not care for it.
2) If you click on someones name, at the top of the page it provides a mini profile like this.
John Doe graduated from Harvard University and is married to Shelia Socks.
Several users reported having access to a new "Memories" option listed below Photos in the left-hand menu on their Profile Pages.
Facebook Memories introduces a timeline to users’ profiles, showing how many statuses were written each year and how many friends were added, along with a sprinkling of photos to illustrate those changes.
We also found some evidence that Facebook may still be testing a filter for the News Feed called "Outside World."
