Updating Angular to 1.4

I would like to upgrade my project to use Angular 1.4. I understand that this is available in Ionic 1.1.0.

I have modified bower.json to use 1.1.0 of ionic.

Then in my project I ran gulp install and ionic lib update.

However, when looking at /www/lib/angular/angular.js it still shows that it is on an older version than 1.4.

How can I update Angular within my project?

It looks like /www/lib/angular/angular.js is from ngCordova.

I ran bower install ngCordova and walked through those steps first.

Then I ran ionic lib update.

I am up to date now.
