     ## NEW: Samples re-structured with `src/` folder (2017-02-02)
  -  All documentation samples have been realigned with the default folder structure of the angular-cli.
  -  That's a step along the road to basing our sample in the angular-cli.

     But it's also good in its own right. 
     It helps clearly separate app code from setup and configuration files.
   
  -  We've updated all samples with an `src/` folder at the project root.
  +  All samples now have a `src/` folder at the project root.

    ## "Style Guide" with _NgModules_ (2016-09-27)
  
    [StyleGuide](style-guide.html) explains 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.
    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.
    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.
