packages/polymer/CHANGELOG.md

+#### 0.16.3+3
+  * Inject the polyfills after any `<base>` tags in the head.
+
+#### 0.16.3+2
+  * Fix invalid warning about missing polymer.html import from the linter.
+  * Update logging package to `<0.12.0`.
+
+#### 0.16.3+1
+  * Update observe to 0.13.1.
+
+#### 0.16.3
+  * Update analyzer to <0.26.0.
+
+#### 0.16.2
+  * Add support for the new `link[rel="x-dart-test"]` tags from the `test`
+    package to the transformer.
+  * The `Future` returned from the default `main` method in
+    `package:polymer/init.dart` now guarantees that it will not complete until
+    all `@initMethod` and `@whenPolymerReady` functions have been executed. This
+    is to support writing tests inside these methods using the new `test`
+    package.
+  * Fix the bootstrap file to return the original result of main.
+
+#### 0.16.1+4
+  * Use `polymer_interop` for everything polymer js related. Projects which only
+  provide/use wrappers around js elements should be able to switch to using that
+  package instead of this one.
+
+#### 0.16.1+3
+  * Update polymer js version to 0.5.5.
+
+#### 0.16.1+2
+  * Update pubspec from `html5lib` to `html`.
+
+#### 0.16.1+1
+  * Switch `html5lib` package dependency to `html`.
+
+#### 0.16.1
+  * Added `@whenPolymerReady` annotation for functions. This will call the
+    function once `Polymer.onReady` completes, reducing the boilerplate in entry
+    points to the following:
+    
+        import 'package:polymer/polymer.dart';
+        export 'package:polymer/init.dart';
+        
+        @whenPolymerReady
+        void onReady() {
+          /// Custom setup code here.
+        }
+
+#### 0.16.0+7
+  * Switch to using `initWebComponents` internally which gives better guarantees
+    around development time ordering of initializers. This should fix most
+    issues related to element registration order.
+
+#### 0.16.0+6
+  * Update `args` constraint.
+  * Pass `bindingStartDelimiters` to the `ImportInlinerTransformer` so it can
+    handle bindings in urls appropriately,
+    [#35](https://github.com/dart-lang/polymer-dart/issues/35).
+
+#### 0.16.0+5
+  * Update `web_components` constraint.
+
+#### 0.16.0+4
+  * Fix static configuration for exported libraries.
+
+#### 0.16.0+3
+  * Increase upper bound of `smoke` package to `<0.4.0`.
+
+#### 0.16.0+2
+  * Update the polyfill injector to work properly for entry points that live in
+    sub-folders.
+
+#### 0.16.0+1
+  * Update analyzer and code_transformers versions and use new mock sdk from
+    code_transformers.
+
+#### 0.16.0
+  * `initPolymer` now returns a `Future<Zone>` instead of a `Zone`. This will
+    likely affect most polymer applications.
+
+    Given a current program:
+
+        main() => initPolymer().run(realMain);
+        realMain() => ...
+
+    This should be translated to:
+    
+        main() => initPolymer().then((zone) => zone.run(realMain));
+        realMain() => ...
+
+    Or alternatively, you can use an @initMethod:
+
+        main() => initPolymer();    
+
+        @initMethod
+        realMain() => ...
+
+  * Dropped support for the experimental bootstrap.
+  * The `polymer` transformer is now integrated with the `initialize`
+    transformer. This means you can now use `@HtmlImport` on library directives.
+    This allows producers of elements to declare their own html dependencies so
+    consumers don't have to know about your html imports at all. See
+    [web_components 0.10.2](https://github.com/dart-lang/web-components/blob/master/CHANGELOG.md#0102)
+    for more information on @HtmlImport.
+  * The `startPolymer` method no longer takes a `deployMode` argument. This is
+    meant as an internal-only method and should not affect apps. It also now
+    returns a `Future`.
+  * The transformer has been heavily refactored and may behave slightly
+    differently. Please file any bugs related to this at
+    https://github.com/dart-lang/polymer-dart/issues/new.
+
+#### 0.15.5+4
+  * Fix for [#23](https://github.com/dart-lang/polymer-dart/issues/23) (0.15.5+3
+    missed an invocation of the observe transformer).
+
+#### 0.15.5+3
+  * Pass more state to the observe transformer so it won't output log files in
+    release mode.
+
+#### 0.15.5+2
+  * Update duplicate css file message.
+
+#### 0.15.5+1
+  * Changes order in which CustomTags are registered to guarantee that the order
+    is deterministic and that within a library superclasses are registered
+    before subclasses. This fixes
+    [17](https://github.com/dart-lang/polymer-dart/issues/17).
+
+#### 0.15.5
+  * Update to polymer js version
+    [0.5.2](https://github.com/Polymer/polymer/releases/tag/0.5.2). This fixes
+    [11](https://github.com/dart-lang/polymer-dart/issues/11).
+
+#### 0.15.4
+  * Fix template if when using template attribute
+    [209](https://github.com/Polymer/TemplateBinding/issues/209).
+  * Renamed `injectBoundHTML` to `injectBoundHtml` and changed its signature to
+    use named instead of positional optional arguments. Also added support for
+    custom `NodeValidator` and/or `TreeSanitizer`. The old version still exists
+    for now with an `@deprecated` annotation.
+
+#### 0.15.3+1
+  * Fix logic for detecting when the compiler is linting within an
+    `auto-binding-dart` template element. This removes some false positive
+    warnings.
+    
+#### 0.15.3
+  * Narrow the constraint on observe to ensure that new features are reflected
+    in polymer's version.
+
+#### 0.15.2
+  * Upgraded to polymer js version
+    [0.5.1](https://github.com/Polymer/polymer/releases/tag/0.5.1).
+    **Dart Note**: Since dirty checking is only a development feature for
+    Polymer Dart, we did not include the functionality to stop dirty checks in
+    inactive windows.
+  * `polymer.js` is now the unminified version, and `polymer.min.js` is the
+    minified version.
+  * Fixed bug where polymer js was creating instances of extended elements in
+    order to check if they had been registered. All dart custom elements now get
+    registered with polymer js using the HTMLElement prototype.
+
+#### 0.15.1+5
+  * Increase code_transformers lower bound and use shared transformers from it.
+
+#### 0.15.1+4
+  * Fix double-registration bug when using exports
+    [21439](http://dartbug.com/21439).
+
+#### 0.15.1+3
+  * Make sure that `dart_support.js` is always appended after `platform.js`,
+    [21435](http://dartbug.com/21435).
+
+#### 0.15.1+2
+  * Handle and warn about cases where a script file is included twice from the
+    same entrypoint [21332](http://dartbug.com/21332).
+
+#### 0.15.1+1
+  * Fix typo in error message polymer#42
+
+#### 0.15.1
+  * Upgraded to polymer [0.4.2][]
+  * No need to include dart_support.js in your entrypoints anymore.
+
+#### 0.15.0+1
+  * Widen web_components version constraint.
+
+#### 0.15.0
+  * Upgraded to polymer 0.4.1
+  * Added Polymer.forceReady method. This forces a ready state regardless of
+    whether or not there are still polymer-element declarations waiting for
+    their class definitions to be loaded.
+  * Added Polymer.waitingFor method. This returns a list of all polymer-element
+    declarations that are still waiting for their class definitions to be
+    loaded.
+  * Add runtime checking of the waitingFor queue and print to the console if a
+    deadlock situation is suspected to help diagnose the white screen of death.
+  * Added injectBoundHTML instance method. This can be used to dynamically
+    inject html that is bound to your current element into a target element.
+
+#### 0.14.3
+  * Warn if the same css file is inlined more than once,
+    [19996](http://dartbug.com/19996).
+  * Don't start moving elements from head to body until we find the first
+    import, [20826](http://dartbug.com/20826).
+  * Add option to not inject platform.js in the build output
+    [20865](http://dartbug.com/20865). To use, set `inject_platform_js` to
+    false in the polymer transformer config section of your pubspec.yaml:
+
+        transformers:
+        - polymer:
+            inject_platform_js: false
+            ...
+
+#### 0.14.2+1
+  * Fix findController function for js or dart wrapped elements. This fixes
+    event bindings when using paper-dialog and probably some other cases,
+    [20931](http://dartbug.com/20931).
+
+#### 0.14.2
+  * Polymer will now create helpful index pages in all folders containing entry
+    points and in their parent folders, in debug mode only
+    [20963](http://dartbug.com/20963).
+
+#### 0.14.1
+  * The build.dart file no longer requires a list of entry points, and you can
+    replace the entire file with `export 'package:polymer/default_build.dart';`
+    [20396](http://dartbug.com/20396).
+  * Inlined imports from the head of the document now get inserted inside a
+    hidden div, similar to the js vulcanizer [20943](http://dartbug.com/20943).
+
+#### 0.14.0+1
+  * Small style improvements on error/warnings page.
+
+#### 0.14.0
+  * Upgraded to polymer 0.4.0 ([polymer-dev#d66a86e][d66a86e]).
+  * The platform.js script is no longer required in Chrome or Dartium
+    (version 36). You can now remove this from your projects for development,
+    and it will be injected when running pub build or pub serve. If you would
+    like the option to not inject platform.js at all in the built output (if you
+    are deploying to chrome exclusively), please star this bug
+    http://dartbug.com/20865.
+  * Fixed invalid linter warning when using event handlers inside an
+    `auto-binding-dart` template, [20913](http://dartbug.com/20913).
+
+#### 0.13.1
+  * Upgraded error messages to have a unique and stable identifier. This
+    requires a version of `code_transformers` newer than `0.2.3`.
+  * Upgraded minimum version constraint on `args` to `0.11.0`.
+
+#### 0.13.0+3
+  * Added a warning about flashes of unstyled content if we can detect a
+    situation that would cause it [20751](http://dartbug.com/20751).
+
+#### 0.13.0+2
+  * Update internal transformers to delete .concat.js and .map files when in
+    release mode, saving about 1MB of space in the built output.
+
+#### 0.13.0+1
+  * Bug fix for http://dartbug.com/18171. Elements that extend other elements
+    but don't have a template will still inherit styles from those elements.
+  * Bug fix for http://dartbug.com/20544. Better runtime logging when attributes
+    are defined on an element but have no corresponding property on the class.
+
+#### 0.13.0
+  * Update to match polymer 0.3.5 ([polymer-dev#5d00e4b][5d00e4b]). There was a
+    breaking change in the web_components package where selecting non-rendered 
+    elements doesn't work, but it shouldn't affect most people. See 
+    https://github.com/Polymer/ShadowDOM/issues/495.
+
+#### 0.12.2+1
+  * Small bug fix for `polymer:new_element`
+
+#### 0.12.2
+  * Fix for [20539](http://dartbug.com/20539). Log widget will now html escape
+    messages.
+  * Fix for [20538](http://dartbug.com/20538). Log widget will now surface lint
+    logs from imported files.
+  * Backward compatible change to prepare for upcoming change of the user agent
+    in Dartium.
+  * `pub run polymer:new_element` now supports specifying a base class.
+    **Note**: only native DOM types and custom elements written in Dart can be
+    extended. Elements adapted from Javascript (like core- and paper- elements)
+    cannot be extended.
+  * other bug fixes in `polymer:new_entry`.
+
+#### 0.12.1
+  * **New**: When running in pub-serve, any warnings and errors detected by the
+    polymer transformers will be displayed in the lower-right corner of your
+    entrypoint page. You can opt-out by adding this option to your pubspec:
+
+        transformers:
+        - polymer:
+            ...
+            inject_build_logs_in_output: false
+
+  * **New**: there are now two template generators in the polymer package! On
+    any project that depends on polymer, you can create template files for a new
+    custom element by invoking:
+
+        pub run polymer:new_element element-name [-o output_dir]
+
+    And, if you invoke:
+
+        pub run polymer:new_entry web/index.html
+
+    we will create a new entry-point file and add it to your pubspec for you.
+
+  * Added the ability to override the stylesheet inlining behavior. There is now
+    an option exposed in the pubspec.yaml called `inline_stylesheets`. There are
+    two possible values, a boolean or a map. If only a boolean is supplied then
+    that will set the global default behavior. If a map is supplied, then the
+    keys should be file paths, and the value is a boolean. You can use the
+    special key 'default' to set the default value.
+
+    For example, the following would change the default to not inline any
+    styles, except for the foo.css file in your web folder and the bar.css file
+    under the foo packages lib directory:
+
+        transformers:
+        - polymer:
+            ...
+            inline_stylesheets:
+                default: false
+                web/foo.css: true
+                packages/foo/bar.css: true
+
+    
+  * Bug fix for http://dartbug.com/20286. Bindings in url attributes will no
+    longer throw an error.
+
+
+#### 0.12.0+7
+  * Widen the constraint on `unittest`.
+
+#### 0.12.0+6
+  * Widen the constraint on analyzer.
+  * Support for `_src` and similar attributes in polymer transformers.
+
+#### 0.12.0+5
+  * Raise the lower bound on the source_maps constraint to exclude incompatible
+    versions.
+
+#### 0.12.0+4
+  * Widen the constraint on source_maps.
+
+#### 0.12.0+3
+  * Fix a final use of `getLocationMessage`.
+
+#### 0.12.0+2
+  * Widen the constraint on barback.
+
+#### 0.12.0+1
+  * Switch from `source_maps`' `Span` class to `source_span`'s `SourceSpan`
+    class.
+
+#### 0.12.0
+ * Updated to match polymer 0.3.4 ([polymer-dev#6ad2d61][6ad2d61]), this
+   includes the following changes:
+     * added @ComputedProperty
+     * @published can now be written using the readValue/writeValue helper
+       methods to match the same timing semantics as Javscript properties.
+     * underlying packages are also updated. Some noticeable changes are:
+       * observe: path-observers syntax is slightly different
+       * polymer_expressions: updating the value of an expression will issue a
+         notification.
+       * template_binding: better NodeBind interop support (for
+         two-way bindings with JS polymer elements).
+ * Several fixes for CSP, including a cherry-pick from polymer.js
+   [commit#3b690ad][3b690ad].
+ * Fix for [17596](https://code.google.com/p/dart/issues/detail?id=17596)
+ * Fix for [19770](https://code.google.com/p/dart/issues/detail?id=19770)
+
+#### 0.11.0+5
+  * fixes web_components version in dependencies
+
+#### 0.11.0+4
+  * workaround for bug
+    [19653](https://code.google.com/p/dart/issues/detail?id=19653)
+
+#### 0.11.0+3
+  * update readme
+
+#### 0.11.0+2
+  * bug fix: event listeners were not in the dirty-checking zone
+  * bug fix: dispatch event in auto-binding
+
+#### 0.11.0+1
+  * Added a workaround for bug in HTML imports (issue
+    [19650](https://code.google.com/p/dart/issues/detail?id=19650)).
+
+#### 0.11.0
+  * **breaking change**: platform.js and dart_support.js must be specified in
+    your entry points at the beginning of `<head>`.
+  * **breaking change**: polymer.html is not required in entrypoints, but it is
+    required from files that use `<polymer-element>`.
+  * **breaking change**: enteredView/leftView were renamed to attached/detached.
+    The old lifecycle methods will not be invoked.
+  * **breaking change**: Event bindings with `@` are no longer supported.
+  * **breaking change**: `@published` by default is no longer reflected as an
+    attribute by default. This might break if you try to use the attribute in
+    places like CSS selectors. To make it reflected back to an attribute use
+    `@PublishedProperty(reflect: true)`.
+
+#### 0.10.1
+  * Reduce the analyzer work by mocking a small subset of the core libraries.
+
+#### 0.10.0+1
+  * Better error message on failures in pub-serve/pub-build when pubspec.yaml
+    is missing or has a wrong configuration for the polymer transformers.
+
+#### 0.10.0
+  * Interop with polymer-js elements now works.
+  * Polymer polyfills are now consolidated in package:web_components, which is
+    identical to platform.js from http://polymer-project.org.
+  * The output of pub-build no longer uses mirrors. We replace all uses of
+    mirrors with code generation.
+  * **breaking change**: Declaring a polymer app requires an extra import to
+    `<link rel="import" href="packages/polymer/polymer.html">`
+  * **breaking change**: "noscript" polymer-elements are created by polymer.js,
+    and therefore cannot be extended (subtyped) in Dart. They can still be used
+    by Dart elements or applications, however.
+  * New feature: `@ObserveProperty('foo bar.baz') myMethod() {...}` will cause
+    myMethod to be called when "foo" or "bar.baz" changes.
+  * Updated for 0.10.0-dev package:observe and package:template_binding changes.
+  * **breaking change**: @initMethod and @CustomTag are only supported on
+    public classes/methods.
+
+#### 0.9.5
+  * Improvements on how to handle cross-package HTML imports.
+
+#### 0.9.4
+  * Removes unused dependency on csslib.
+
+#### 0.9.3+3
+  * Removes workaround now that mirrors implement a missing feature. Requires
+    SDK >= 1.1.0-dev.5.0.
+
+#### 0.9.3+2
+  * Fix rare canonicalization bug
+    [15694](https://code.google.com/p/dart/issues/detail?id=15694)
+
+#### 0.9.3+1
+  * Fix type error in runner.dart
+    [15649](https://code.google.com/p/dart/issues/detail?id=15649).
+
+#### 0.9.3
+  * pub-build now runs the linter automatically
+
+#### 0.9.2+4
+  * fix linter on SVG and MathML tags with XML namespaces
+
+#### 0.9.2+3
+  * fix [15574](https://code.google.com/p/dart/issues/detail?id=15574),
+    event bindings in dart2js, by working around issue
+    [15573](https://code.google.com/p/dart/issues/detail?id=15573)
+
+#### 0.9.2+2
+  * fix enteredView in dart2js, by using custom_element >= 0.9.1+1
