Set commentDirectivesEnabled and cssClassDirectivesEnabled to false in Angular

Question

I'm attempting to make some small tweaks to my config to hopefully improve performance slightly. I read through the Angular docs here and they mention disabling comment and CSS class directives. I tried to do so with the below code in my config, but I keep getting TypeError: $compileProvider.commentDirectivesEnabled is not a function or TypeError: $compileProvider.cssClassDirectivesEnabled is not a function errors.

Note: I'm running Angular 1.4.9

'use strict';

angular.module('app')
  .config(compilationConfig)
;

compilationConfig.$inject = ['$compileProvider'];

function compilationConfig($compileProvider) {
  $compileProvider.debugInfoEnabled(false);
  $compileProvider.commentDirectivesEnabled(false);
  $compileProvider.cssClassDirectivesEnabled(false);
}

Solved this myself. This functionality was introduced in 1.6.0 so you need to upgrade to take advantage of these methods.
