  # Documentation Change Log

  The Angular documentation is a living document with continuous improvements.
  This log calls attention to recent significant changes.

  ## Sync with Angular v.2.1.1 (2016-10-21)
  Docs and code samples updated and tested with Angular v.2.1.0 

  ## npm _@types_ packages replace _typings_ (2016-10-20)
  Documentation samples now get TypeScript type information for 3rd party libraries
  from npm `@types` packages rather than with the _typings_ tooling.
  The `typings.json` file is gone.

  The "[Angular 1 Upgrade](upgrade.html)" guide reflects this change.
  The `package.json` installs `@types/angular` and several `@types/angular-...`
  packages in support of upgrade; these are not needed for pure Angular 2 development.

  ## "Template Syntax" explains two-way data binding syntax (2016-10-20)
  Demonstrates how to two-way data bind to a custom Angular component and
  re-explains `[(ngModel)]` in terms of the basic `[()]` syntax.

  ## BREAKING CHANGE: `in-memory-web-api` (v.0.1.11) delivered as esm umd (2016-10-19)
  This change supports ES6 developers and aligns better with typical Angular libraries.
  It does not affect the module's API but it does affect how you load and import it.
  See the <a href="https://github.com/angular/in-memory-web-api/blob/master/CHANGELOG.md#0113-2016-10-20" target="_blank">change note</a>
  in the `in-memory-web-api` repo.

  ## "Router" _preload_ syntax and _:enter_/_:leave_ animations (2016-10-19)
  The router can lazily _preload_ modules _after_ the app starts and
  _before_ the user navigates to them for improved perceived performance.
  
  New `:enter` and `:leave` aliases make animation more natural. 

  ## Sync with Angular v.2.1.0 (2016-10-12)
  Docs and code samples updated and tested with Angular v.2.1.0 

  ## NEW "Ahead of Time (AoT) Compilation" cookbook (2016-10-11)
  The NEW [Ahead of Time (AoT) Compilation](../cookbook/aot-compiler.html) cookbook
  explains what AoT compilation is and why you'd want it.
  It demonstrates the basics with a QuickStart app
  followed by the more advanced considerations of compiling and bundling the Tour of Heroes.

  ## Sync with Angular v.2.0.2 (2016-10-6)
  Docs and code samples updated and tested with Angular v.2.0.2 

  ## "Routing and Navigation" guide with the _Router Module_ (2016-10-5)
  The [Routing and Navigation](router.html) guide now locates route configuration
  in a _Routing Module_. 
  The _Routing Module_ replaces the previous _routing object_ involving the `ModuleWithProviders`.

  All guided samples with routing use the _Routing Module_ and prose content has been updated,
  most conspicuously in the 
  [NgModule](ngmodule.html) guide and [NgModule FAQ](../cookbook/ngmodule-faq.html) cookbook.

  ## New "Internationalization" Cookbook (2016-09-30)

  Added a new [Internationalization (i18n)](../cookbook/i18n.html) cookbook that shows how
  to use Angular "i18n" facilities to translate template text into multiple languages.

  ## "angular-in-memory-web-api" package rename (2016-09-27)

  Many samples use the `angular-in-memory-web-api` to simulate a remote server.
  This library is also useful to you during early development before you have a server to talk to.

  The package name was changed from "angular2-in-memory-web-api" which is still frozen-in-time on npm.
  The new "angular-in-memory-web-api" has new features. 
  <a href="https://github.com/angular/in-memory-web-api/blob/master/README.md" target="_blank">Read about them on github</a>.

  ## "Style Guide" with _NgModules_ (2016-09-27)

  [StyleGuide](style-guide.html) explains our recommended conventions for Angular modules (NgModule).
  Barrels now are far less useful and have been removed from the style guide;
  they remain valuable but are not a matter of Angular style.
  We also relaxed the rule that discouraged use of the `@Component.host` property.

  ## _moduleId: module.id_ everywhere (2016-09-25)

  Sample components that get their templates or styles with `templateUrl` or `styleUrls`
  have been converted to _module-relative_ URLs.
  We added the `moduleId: module.id` property-and-value to their `@Component` metadata.
  
  This change is a requirement for compilation with AoT compiler when the app loads
  modules with SystemJS as the samples currently do.

  ## "Lifecycle Hooks" guide simplified (2016-09-24)

  The [Lifecycle Hooks](lifecycle-hooks.html) guide is shorter, simpler, and 
  draws more attention to the order in which Angular calls the hooks.
