Is frame relay still used?

in CCNA & CCENT
I'm reading up frame relay chapters for CCNA. Just to gain a bit real-world knowledge, what's the current state of frame-relay? Is this a mature technology or retired technology? Are there competing technologies for WAN connectivity?

Then does any Cisco course explain MPLS? If not, where to learn about MPLS?
I wouldn't go that far. Vastly diferent technologies.
That's it though. As mentioned before it's a fading technology.
