Tom Clancy´s Ghost Recon: Wildlands Discussion
It does use a queue or scheduling system but it's generally only a few hours of wait before it downloads it automatically without you starting it manually by checking the downloads section of Steam.
For UPlay just starting the game should prompt for a update or ticking the auto-update option if that's off should refresh and update any supported newer game.
(Older ones on UPlay use a separate gu.exe system but that's from a few years ago and doesn't apply here.)
EDIT - And that on the main menu is just a build number, forgot what 1.0 was called though but I'm guessing that number above corresponds to 1.15
