### BREAKING CHANGES

* Users outside of Google don't usually need closure annotations hence `annotateForClosureCompiler` is turned off by default. In case users want to emit closure compatible code, they need to install `tsickle` and enable opt it this feature.

* We no longer use node-sass by default, instead we use sass (dart-sass).

While in most cases this should not have an impact the generated code, dart sass has some differences from Ruby Sass. See https://github.com/sass/dart-sass#behavioral-differences-from-ruby-sass for more details

If you wish to use node-sass instead of sass you need to install node-sass as a dev dependency.

npm users
```
npm install node-sass --save-dev
```
yarn users
```
yarn add node-sass --dev
```

### BREAKING CHANGES

* UMD module ids for rxjs v5 are now longer provided out-ot-the-box.

### BREAKING CHANGES

Removes several deprecated code items.
  - option `sassIncludePaths` is removed, please use `styleIncludePaths` instead
  - option `workingDirectory` is removed, removed corresponding getter from `NgPackage` class
  - method `createNgPackage` removed from programmatic API
  - removed `NgArtefacts` class from API
  - removed `BuildStep` interface from API
  - removed tarball generation ([#721](https://github.com/ng-packagr/ng-packagr/issues/721))

There were some important changes, mainly related to `rollup`, most of the options and functionality provided by `rollup` plugins (comments & license) have been removed, due to the fact this is not inline with APF V6 as one will end up with different outputs in different modules.
  - **`comments` option has been removed** 
  - **`licensePath` option has been removed** 

In APF V6, it is recommanded to not embed dependencies due to the fact that it will end up having multiple copies of the same library in a single application.

  - **`embedded` option has been removed and the original functionality was dropped** as it increased the chance of having 2 copies of the same library. The recommended migration is to switch to `bundledDependencies`

More info in the APF v6 spec: https://docs.google.com/document/d/1CZC2rcpxffTDfRDs6p1cfbmKNLA6x5O-NtkJglDaBVs/preview

Documentation on npm bundled dependencies: http://npm.github.io/using-pkgs-docs/package-json/types/bundleddependencies.html 

#### Tarball generation

As we don't generate a tarball by default anymore, you should manually, after the build, create it by running [`npm pack`](https://docs.npmjs.com/cli/pack) in the `dist` folder of your library. See [#802](https://github.com/ng-packagr/ng-packagr/issues/802) and [#738 (comment)](https://github.com/ng-packagr/ng-packagr/pull/738#issuecomment-379457152) for more information.

# [2.0.0](https://github.com/ng-packagr/ng-packagr/compare/v2.0.0-rc.13...v2.0.0) (2018-02-05)

Version 2 of ng-packagr is targeting Angular 5 (and beyond).
Update your projects by:

```bash
$ yarn add --dev ng-packagr@^2.0.0 @angular/compiler@^5.0.0 @angular/compiler-cli@^5.0.0 tsickle
```

### Migrating from v1 (Breaking changes from v1.6.0 to v2.0.0)

* Users now need to install `@angular/compiler`, `@angular/compiler-cli`, `typescript`, and `tsickle` to the `devDependency` section of their project (if not already installed). ng-packagr uses both the TypeScript and the Angular compiler version provided by the user workspace.
* The setting for external dependencies (`lib.externals`) has been removed in favour of `lib.umdModuleIds` which is now just used to provide the UMD module identifiers of external dependencies.
  By default, all dependencies are now treated as externals and thus are not embedded in the final bundle.
  If a dependency should be embedded in the distributables, it needs to be explicity added to `lib.embedded`.
  Please consult the updated README on migrating your package confguration from `lib.externals` to `lib.umdModuleIds` and `lib.embedded`.
* Discovery of primary and secondary entry points is changed to read from the following file sources. File locations are tried in this order:
  * `package.json` with `ngPackage` property
  * `ng-package.json` (requires a `package.json` as sibling)
  * `ng-package.js` (with a default export, requires a `package.json` as sibling)
* Setting `ngPackage.src` has no effect any more. The source directory (base path) is equivalent to the location of the (primary) `ng-package.json`, `package.json`, or `ng-package.js`.
* UMD Module IDs of packages have been changed: when you published a scoped npm package, e.g. `@sample/core`, the UMD module ID used to be `core` including only the second part of the npm package name. With this change, the UMD module ID is now `sample.core`. For secondary entrypoints, e.g. `@sample/core/testing`, the UMD module ID now also includes every part of the npm package name, e.g. `sample.core.testing`. Publishing your npm packages built with this version of ng-packagr causes a new UMD module ID to be generated. Users of your library need to update their configuration, e.g. when using SystemJS!
