Lr 5.4 Update?

I have a current CC account and have both Ps and Lr installed. Today CC advised that there was an update for Ps available which I downloaded. However, I have not had any notification for the update for Lr 5.3 to 5.4. I checked Help in Lr and on "check for updates" was advised that my software is up to date? How do I update to 5.4?
