Angular CLI 1.1 is out and here are some notable new features:

• outputs smaller and faster bundles by default,
• now comes with a new welcome screen when creating a new application,
• has better support for serving with a different public URL, and
• now supports fixing generated code according to your linting preferences, e.g. use double-quotes instead of single quotes for strings.

Along with over 50 fixes!
