Using tabs template created with `ionic version 2.1.1` & `cordova version 6.4.0` tried adding `es6-shim` but can not get this simple `number pipe` to work ```auto {{item.sum | number:'1.2-2'}} ``` Tried to install `cordova-plugin-crosswalk-webview` resulting in `minSdkVersion="16"` and `targetSdkVersion="23"` tested on updated `Android 6.0.1` device Any pointers on what I’m missing? ---

The [DecimalPipe](https://angular.io/docs/ts/latest/api/common/index/DecimalPipe-pipe.html) docs mention > WARNING: this pipe uses the Internationalization API which is not yet available in all browsers and may require a polyfill. ---

Beyond that, I have been told there are issues with Pipes in Angular 2.0.0 when using `ngc`. We’re looking at upgrading to the latest version which fixes the issue for RC2. Thanks, Dan ---

Was under the impression that crosswalk wouldn’t need the polyfill for Intl. Any input on what the preferred way is, for including this in an Ionic2, Typescript app? ---

Is there a roadmap where you can read about upcoming release dates? ETA? ---

@danielwertheim You’re right, that browser [should support](http://caniuse.com/#feat=internationalization) Intl. Must be the issue that @danbucholtz mentioned, i.e. [angular/angular#11642](https://github.com/angular/angular/issues/11642). You should be able to upgrade your Angular dependencies without waiting for a new Ionic release; I’m using Angular 2.1.x and it seems to work fine. ---

We’ve seen parts of ionic-angular break when upgrading to the latest Angular compiler so there were some unintended breaking changes in the Angular release. We’re working on updating for RC2. Thanks, Dan ---

So you don’t recommend updating? What is the recommendation then? Polyfill? If so, what is the recommendation in Ionic2 with TS for bringing in polyfills? Thanks, //Daniel ---

Tried with getting Angular 2.1.2 in place as well as latest zone.js and rxjs. Then the `ionic build` command fails. Guess I’ll just remove the usage of the pipe and await next release of Ionic.
