 #### 0.10.2
   * Added the `HtmlImport` annotation. This can be added to any library
     declaration and it will inject an html import to the specified path into the
     head of the current document, which allows dart files to declare their html
     dependencies. Paths can be relative to the current dart file or they can be
     in `package:` form.
 
     *Note*: Html imports included this way cannot contain dart script tags. The
     mirror based implementation injects the imports dynamically and dart script
     tags are not allowed to be injected in that way.

+    *Note*:  Relative urls cannot be used in inlined script tags. Either move
     the script code to a Dart file, use a `package:` url, or use a normal HTML
     import. See https://github.com/dart-lang/web-components/issues/6.
 
   * Added a `web_components` transformer. This should be used in place of the
     `initialize` transformer if that already exists in your application (it will
     call that transformer). This will inline html imports (including @HtmlImport
     annotations) into the head of your document at compile time, it can be used
     like this:
 
         transformers:
         - web_components:
             entry_points:
               - web/index.html
-

     If no `entry_points` option is supplied then any html file under `web` or
     `test` will be treated as an entry point.
 
 #### 0.10.1
   * Added the `CustomElementProxy` annotation. This can be added to any class
     which proxies a javascript custom element and is the equivalent of calling
     `registerDartType`. In order to use this you will need to be using the
     `initialize` package, and call its `run` method from your main function. It
     is also recommended that you include the transformer from that package to
     remove the use of mirrors at runtime, see

 #### 0.9.0
   * Updated to platform version 0.4.2, internally a deprecated API was removed,
     hence the bump in the version number.
 
   * split dart_support.js in two. dart_support.js only contains what is
     necessary in order to use platform.js,
     interop_support.js/interop_support.html can be imported separately when
     providing Dart APIs for js custom elements.

     the customElementsTakeRecords function.
   * **Breaking Change** The customElementsTakeRecords function now has an
     an optional argument `node`. There is no longer a single global observer,
     but one for each ShadowRoot and one for the main document. The observer that
     is actually used defaults to the main document, but if `node` is supplied
     then it will walk up the document tree and use the first observer that it
     finds.
