The timeline feature allows you to see right back, easily, to different years and revisit old status updates, photos, activity on your account etc.
The best feature has to be the new profile cover which you get to choose from all of your photos, in addition to your normal profile picture.
I cannot wait for everyone to get this version as at the moment it is only visible to those who have the update, meaning others can't see my profile as I can, and I can only see the old version for everyone else as well.
What do you think? Have you got the new version yet? Do you want it or are you against the change?
