Fedora :: Fedora 13 File Permission Notation - Dot Meaning?

I may not have noticed in other Fed releases, but in Fed 13 I am seeing a dot at the end of all file permissions. Example:

[pjs@linux ~]$ ls -ld Documents
drwxr-xr-x. 62 pjs pjs 4096 Jul 11 09:53 Documents

Even on files I create myself:

[pjs@linux ~]$ touch foo
[pjs@linux ~]$ ls -l foo
-rw-rw-r--. 1 pjs pjs 0 Jul 11 10:46 foo

It is the same throughout the fs. I have disabled as much of SELinux as I can. What does the dot mean?
