I just installed the 3rd service pack for XP Pro.

Is there any new functionality in it or just security fixes?

The release notes for XP SP3 can be found here:
And the overview of SP3 is here:

They're quite big, so see for yourself :)

I guess the most prominent of the new features would be the support of WPA2 in wireless networks and SHA2 (aka SHA256/384/512) in TLS protocol.
