BREAKING CHANGE:

ion-toggle no longer has an isolate scope.
This will break your toggle only if you were relying upon the toggle
having an isolate scope: if you were referencing `$parent.value` as
the ng-disabled attribute, for example.

Change your code from this:

<ion-toggle ng-disabled="{{$parent.isDisabled}}"></ion-toggle>

To this:

<ion-toggle ng-disabled="{{isDisabled}}"></ion-toggle>
fix(sidemen): scroll false causes sidemenu content to disappear. Closes #1485
fix(slidebox): default to not autoplay
fix(loading): stop resize flicker when showing & changing text
style(platform.scss): remove nested, unclosed comment

This nested unclosed comment breaks autoprefixer's parsing and causes
it to spike to 100% cpu.

No breaking changes in this commit. see diegonetto/generator-ionic#38
