The Ionic Framework team would like to re-evaluate our approach to improving customization options when building mobile applications. We are looking at other solutions that a) make customizing an app UI easier and b) are applicable to a broader set of developers.
BREAKING CHANGE:
`ActionSheetAttributes`, `AlertAttributes`, `AlertTextareaAttributes`, `AlertInputAttributes`, `LoadingAttributes`, `ModalAttributes`, `PickerAttributes`, `PopoverAttributes`, and `ToastAttributes` have been removed. Developers should use `{ [key: string]: any }` instead.
* chore: internal import updates to improve bundling
- Rename keyboard.ts so it has a good filename after custom element bundling
- Import util fns directly instead of from top level index
- Do not export with *
* chore(angular): bump ng-packagr

This updates the components and the docs so that translucent is only applied when backdrop filter is supported, this prevents it from being applied when viewing iOS in Chrome, for example.
