packages/web_components/CHANGELOG.md

+#### 0.11.4+2
+  * Don't inline type="css" imports.
+
+#### 0.11.4+1
+  * Fix erroneous messages about invalid package paths in html imports
+    [72](https://github.com/dart-lang/polymer-dart/issues/72).
+
+#### 0.11.4
+  * Update to analyzer `<0.26.0`.
+
+#### 0.11.3+1
+  * Fix bootstrap to return the result of the original main.
+
+#### 0.11.3
+  * Add support for the new `link[rel="x-dart-test"]` tags from the `test`
+    package to the transformer.
+
+#### 0.11.2
+  * Copied `DomProxyMixin` from `custom_element_apigen` to this package and
+    renamed it `CustomElementProxyMixin`. This can be mixed into any class that
+    is using the `@CustomElementProxy` annotation and provides easy access to
+    the underlying javascript element via the `jsElement` getter. For instance
+    the following is a simple example of a dart class that wraps a custom
+    javascript element `foo-element` with a method `doFoo` and a property `foo`.
+
+        @CustomElementProxy('foo-element')
+        class FooElement extends HtmlElement with CustomElementProxyMixin {
+          FooElement.created() : super.created();
+
+          void doFoo(int arg1) => jsElement.callMethod('doFoo', [arg1]);
+
+          int get foo => jsElement['foo'];
+          void set foo(int newFoo) {
+            jsElement['foo'] = newFoo;
+          }
+        }
+
+#### 0.11.1+3
+  * Switch `html5lib` package dependency to `html`.
+
+#### 0.11.1+2
+  * Added a runtime warning about bad packages paths in html imports to
+    `initWebComponents`.
+
+#### 0.11.1+1
+  * fixes unknown HTML elements if using interop_support.js
+
+#### 0.11.1
+  * Added `initWebComponents` function which performs html import aware
+    initialization of an application. This is done by crawling all imported
+    documents for dart script tags and initializing them. Any applications using
+    this package should switch to this method instead of calling `run` from the
+    `initialize` package directly.
+  * You may also now just export `package:web_components/init.dart` to
+    initialize your app, and then stick your startup code inside a method marked
+    with `@initMethod`, for instance:
+
+        library my_app;
+        export 'package:web_components/init.dart';
+
+        @initMethod
+        void startup() {
+          // custom app code here.
+        }
+
+#### 0.11.0
+  * Add `bindingStartDelimiters` option to the `ImportInlinerTransformer`. Any
+    urls which contain any of the supplied delimiters before the first `/` will
+    be left alone since they can't be reasoned about. If you want these urls to
+    be treated as relative to the current path you should add a `./` in front.
+  * The `ScriptCompactorTransformer` now names its bootstrap file based on the
+    entry point html file, instead of the original dart file. This is ensure it
+    is the original package.
+
+#### 0.10.5+3
+  * Fix normalization of relative paths inside of deep relative imports,
+    https://github.com/dart-lang/polymer-dart/issues/30.
+  * Update analyzer and code_transformers versions and use new mock sdk from
+    code_transformers.
+
+#### 0.10.5+2
+  * Append html imports in front of the dart script tag, if one exists in
+    `document.head`.
+
+#### 0.10.5+1
+  * Fix @HtmlImport with relative paths from within folders in deployment mode.
+
+#### 0.10.5
+  * Update `ImportCrawler` with support for pre-parsed initial documents. This
+    allows it to work better with other transformers in the same step (you can
+    pass in a modified document).
+
+#### 0.10.4+2
+  * Fix `@CustomElement` test in internet explorer.
+
+#### 0.10.4+1
+  * Update `initialize` lower bound to get bug fixes.
+  * Make sure to always use `path.url` in transformers.
+
+#### 0.10.4
+  * Added `CustomElement` annotation. This can be added to any class to register
+    it with a tag in the main document.
+  * Added a `web_components.dart` file which exports all the annotations
+    provided by this package. Note that in later breaking releases
+    `html_import_annotation.dart` and `custom_element_proxy.dart` will likely
+    move into the `src` folder, so switching to the `web_components.dart` import
+    is recommended.
+
+#### 0.10.3
+  * Added `generateWebComponentsBootstrap` method to the main `web_components`
+    transformer file which accepts a `Transform` and a `Resolver`. You can use
+    this function from any transformer and share the resolver you already have.
+  * Fixed up the bootstrap call in `ScriptCompactor` to not use `=>` syntax
+    since it has a declared return type of `void`. This could previously cause
+    a checked mode error if the original program returned something from `main`.
+
+#### 0.10.2+1
+  * Minor cleanup to changelog and tests.
+  * ImportInliner now throws warnings instead of errors.
+
+#### 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
+    [initialize](https://github.com/dart-lang/initialize) for more information.
+
+#### 0.10.0
+  * Updated to the `0.5.1` js version.
+  * **Breaking Change** To remain consistent with the js repository all the
+    `platform.js` has been replaced with `webcomponents.js`. Also, the default
+    file is now unminified, and the minified version is called
+    `webcomponents.min.js`.
+
+#### 0.9.0+1
+  * Remove all `.map` and `.concat.js` files during release mode.
+
+#### 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.
+
+#### 0.8.0
+  * Re-apply changes from 0.7.1+1 and also cherry pick 
+    [efdbbc](https://github.com/polymer/CustomElements/commit/efdbbc) to fix
+    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.
+
+#### 0.7.1+2
+  * Revert the change from 0.7.1+1 due to redness in FF/Safari/IE.
+
+#### 0.7.1+1
+  * Cherry pick [f280d](https://github.com/Polymer/ShadowDOM/commit/f280d) and
+    [165c3](https://github.com/Polymer/CustomElements/commit/165c3) to fix
+    memory leaks.
+
+#### 0.7.1
+  * Update to platform version 0.4.1-d214582.
+
+#### 0.7.0+1
+  * Cherry pick https://github.com/Polymer/ShadowDOM/pull/506 to fix IOS 8.
+
+#### 0.7.0
+  * Updated to 0.4.0-5a7353d release, with same cherry pick as 0.6.0+1.
+  * Many features were moved into the polymer package, this package is now
+    purely focused on polyfills.
+  * Change Platform.deliverDeclarations to 
+    Platform.consumeDeclarations(callback).
+  * Cherry pick https://github.com/Polymer/ShadowDOM/pull/505 to fix mem leak.
+
+#### 0.6.0+1
+  * Cherry pick https://github.com/Polymer/ShadowDOM/pull/500 to fix
+    http://dartbug.com/20141. Fixes getDefaultComputedStyle in firefox.
+
+#### 0.6.0
+  * Upgrades to platform master as of 8/25/2014 (see lib/build.log for details).
+    This is more recent than the 0.3.5 release as there were multiple breakages
+    that required updating past that.
+  * There is a bug in this version where selecting non-rendered elements doesn't
+    work, but it shouldn't affect most people. See 
+    https://github.com/Polymer/ShadowDOM/issues/495.
+
+#### 0.5.0+1
+  * Backward compatible change to prepare for upcoming change of the user agent
+    in Dartium.
+
+#### 0.5.0
+  * Upgrades to platform version 0.3.4-02a0f66 (see lib/build.log for details).
+
+#### 0.4.0
+  * Adds `registerDartType` and updates to platform 0.3.3-29065bc
+    (re-applies the changes in 0.3.5).
+
+#### 0.3.5+1
+  * Reverts back to what we had in 0.3.4. (The platform.js updates in 0.3.5 had
+    breaking changes so we are republishing it in 0.4.0)
+
+#### 0.3.5
+  * Added `registerDartType` to register a Dart API for a custom-element written
+    in Javascript.
+  * Updated to platform 0.3.3-29065bc
+
+#### 0.3.4
+  * Updated to platform 0.2.4 (see lib/build.log for details)
