 ### BREAKING CHANGES
 
+* all: we've updated our packaging to match angular/angular's packaging.  If you're using System.js in your project, you will probably want to
+switch to using our UMD bundles.  Example config:
+
+```ts
+'@angular2-material/core': {
+    format: 'cjs',
+    main: 'core.umd.js'
+  }
+```
+
+You can see a more detailed example in our demo app's system config [here](https://github.com/angular/material2/blob/master/src/demo-app/system-config.ts).
+
 * input: `md-input` attributes now match the casing of native attributes. Previously they were camel-cased; now they are all lowercase. 
 Example: `autoComplete` is now `autocomplete`.   See [#1066](https://github.com/angular/material2/pull/1066) for a full list.
 * overlay: overlays are now synchronous. This means actions like creating an overlay no longer return a promise.
