Sorry, Ivy will not ship in Angular 7. I had heard the rumours but this tweet from Brad Green seems to confirm it. Angular 7 will not include Ivy.
Sorry ivy isn’t in 7 but will come as soon as we can get it out. Should be before v8 as it’s not a breaking change.

Ivy is the new Angular compiler that promises much much smaller builds.
Progress is currently at 92% so not too much longer to wait.
I don’t mind the delay. Rushing out a buggy version of the Ivy renderer would be a mistake.
