package. We will also note important changes to the polyfill packages (observe,
web_components, and template_binding) if they impact polymer.
+#### Pub version 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.
+
+#### Pub version 0.12.2+1
+ * Small bug fix for `polymer:new_element`
+
+#### Pub version 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`.
+
#### Pub version 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

The goal is to allow users to avoid the \n most obvious pitfalls and do so without compromising performance significantly. \n For ShadowDOM styling that's not covered here, a set of best practices\n can be provided that should allow users to accomplish more complex styling.\n\n The following is a list of specific ShadowDOM styling features and a brief\n discussion of the approach used to shim.\n\n Shimmed features:\n\n * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n element using the :host rule. To shim this feature, the :host styles are \n reformatted and prefixed with a given scope name and promoted to a \n document level stylesheet.\n For example, given a scope name of .foo, a rule like this:\n \n :host {\n background: red;\n }\n }\n \n becomes:\n \n .foo {\n background: red;\n }\n \n * encapsultion: Styles defined within ShadowDOM, apply only to \n dom inside the ShadowDOM. Polymer uses one of two techniques to imlement\n this feature.\n \n By default, rules are prefixed with the host element tag name \n as a descendant selector. This ensures styling does not leak out of the 'top'\n of the element's ShadowDOM. For example,\n\n div {\n font-weight: bold;\n }\n \n becomes:\n\n x-foo div {\n font-weight: bold;\n }\n \n becomes:\n\n\n Alternatively, if Platform.ShadowCSS.strictStyling is set to true then \n selectors are scoped by adding an attribute selector suffix to each\n simple selector that contains the host element tag name. Each element \n in the element's ShadowDOM template is also given the scope attribute. \n Thus, these rules match only elements that have the scope attribute.\n For example, given a scope name of x-foo, a rule like this:\n \n div {\n font-weight: bold;\n }\n \n becomes:\n \n div[x-foo] {\n font-weight: bold;\n }\n\n Note that elements that are dynamically added to a scope must have the scope\n selector added to them manually.\n\n * upper/lower bound encapsulation: Styles which are defined outside a\n shadowRoot should not cross the ShadowDOM boundary and should not apply\n inside a shadowRoot.\n\n This styling behavior is not emulated. Some possible ways to do this that \n were rejected due to complexity and/or performance concerns include: (1) reset\n every possible property for every possible selector for a given scope name;\n (2) re-implement css in javascript.\n \n As an alternative, users should make sure to use selectors\n specific to the scope in which they are working.\n \n * ::distributed: This behavior is not emulated. It's often not necessary\n to style the contents of a specific insertion point and instead, descendants\n of the host element can be styled selectively. Users can also create an \n extra node around an insertion point and style that node's contents\n via descendent selectors. For example, with a shadowRoot like this:\n \n <style>\n ::content(div) {\n background: red;\n }\n </style>\n <content></content>\n \n could become:\n \n <style>\n / *@polyfill .content-container div * / \n ::content(div) {\n background: red;\n }\n </style>\n <div class=\"content-container\">\n <content></content>\n </div>\n \n Note the use of @polyfill in the comment above a ShadowDOM specific style\n declaration. This is a directive to the styling shim to use the selector \n in comments in lieu of the next selector when running under polyfill.\n*/\n(function(scope) {\n\nvar ShadowCSS = {\n strictStyling: false,\n registry: {},\n // Shim styles for a given root associated with a name and extendsName\n // 1. cache root styles by name\n // 2. optionally tag root nodes with scope name\n // 3. shim polyfill directives /* @polyfill */ and /* @polyfill-rule */\n // 4. shim :host and scoping\n shimStyling: function(root, name, extendsName) {\n var scopeStyles = this.prepareRoot(root, name, extendsName);\n var typeExtension = this.isTypeExtension(extendsName);\n var scopeSelector = this.makeScopeSelector(name, typeExtension);\n // use caching to make working with styles nodes easier and to facilitate\n // lookup of extendee\n var cssText = stylesToCssText(scopeStyles, true);\n cssText = this.scopeCssText(cssText, scopeSelector);\n // cache shimmed css on root for user extensibility\n if (root) {\n root.shimmedStyle = cssText;\n }\n // add style to document\n this.addCssToDocument(cssText, name);\n },\n /*\n * Shim a style element with the given selector.

The goal is to allow users to avoid the \n most obvious pitfalls and do so without compromising performance significantly. \n For ShadowDOM styling that's not covered here, a set of best practices\n can be provided that should allow users to accomplish more complex styling.\n\n The following is a list of specific ShadowDOM styling features and a brief\n discussion of the approach used to shim.\n\n Shimmed features:\n\n * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n element using the :host rule. To shim this feature, the :host styles are \n reformatted and prefixed with a given scope name and promoted to a \n document level stylesheet.\n For example, given a scope name of .foo, a rule like this:\n \n :host {\n background: red;\n }\n }\n \n becomes:\n \n .foo {\n background: red;\n }\n \n * encapsultion: Styles defined within ShadowDOM, apply only to \n dom inside the ShadowDOM. Polymer uses one of two techniques to imlement\n this feature.\n \n By default, rules are prefixed with the host element tag name \n as a descendant selector. This ensures styling does not leak out of the 'top'\n of the element's ShadowDOM. For example,\n\n div {\n font-weight: bold;\n }\n \n becomes:\n\n x-foo div {\n font-weight: bold;\n }\n \n becomes:\n\n\n Alternatively, if Platform.ShadowCSS.strictStyling is set to true then \n selectors are scoped by adding an attribute selector suffix to each\n simple selector that contains the host element tag name. Each element \n in the element's ShadowDOM template is also given the scope attribute. \n Thus, these rules match only elements that have the scope attribute.\n For example, given a scope name of x-foo, a rule like this:\n \n div {\n font-weight: bold;\n }\n \n becomes:\n \n div[x-foo] {\n font-weight: bold;\n }\n\n Note that elements that are dynamically added to a scope must have the scope\n selector added to them manually.\n\n * upper/lower bound encapsulation: Styles which are defined outside a\n shadowRoot should not cross the ShadowDOM boundary and should not apply\n inside a shadowRoot.\n\n This styling behavior is not emulated. Some possible ways to do this that \n were rejected due to complexity and/or performance concerns include: (1) reset\n every possible property for every possible selector for a given scope name;\n (2) re-implement css in javascript.\n \n As an alternative, users should make sure to use selectors\n specific to the scope in which they are working.\n \n * ::distributed: This behavior is not emulated. It's often not necessary\n to style the contents of a specific insertion point and instead, descendants\n of the host element can be styled selectively. Users can also create an \n extra node around an insertion point and style that node's contents\n via descendent selectors. For example, with a shadowRoot like this:\n \n <style>\n ::content(div) {\n background: red;\n }\n </style>\n <content></content>\n \n could become:\n \n <style>\n / *@polyfill .content-container div * / \n ::content(div) {\n background: red;\n }\n </style>\n <div class=\"content-container\">\n <content></content>\n </div>\n \n Note the use of @polyfill in the comment above a ShadowDOM specific style\n declaration. This is a directive to the styling shim to use the selector \n in comments in lieu of the next selector when running under polyfill.\n*/\n(function(scope) {\n\nvar ShadowCSS = {\n strictStyling: false,\n registry: {},\n // Shim styles for a given root associated with a name and extendsName\n // 1. cache root styles by name\n // 2. optionally tag root nodes with scope name\n // 3. shim polyfill directives /* @polyfill */ and /* @polyfill-rule */\n // 4. shim :host and scoping\n shimStyling: function(root, name, extendsName) {\n var scopeStyles = this.prepareRoot(root, name, extendsName);\n var typeExtension = this.isTypeExtension(extendsName);\n var scopeSelector = this.makeScopeSelector(name, typeExtension);\n // use caching to make working with styles nodes easier and to facilitate\n // lookup of extendee\n var cssText = stylesToCssText(scopeStyles, true);\n cssText = this.scopeCssText(cssText, scopeSelector);\n // cache shimmed css on root for user extensibility\n if (root) {\n root.shimmedStyle = cssText;\n }\n // add style to document\n this.addCssToDocument(cssText, name);\n },\n /*\n * Shim a style element with the given selector.

The goal is to allow users to avoid the \n most obvious pitfalls and do so without compromising performance significantly. \n For ShadowDOM styling that's not covered here, a set of best practices\n can be provided that should allow users to accomplish more complex styling.\n\n The following is a list of specific ShadowDOM styling features and a brief\n discussion of the approach used to shim.\n\n Shimmed features:\n\n * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n element using the :host rule. To shim this feature, the :host styles are \n reformatted and prefixed with a given scope name and promoted to a \n document level stylesheet.\n For example, given a scope name of .foo, a rule like this:\n \n :host {\n background: red;\n }\n }\n \n becomes:\n \n .foo {\n background: red;\n }\n \n * encapsultion: Styles defined within ShadowDOM, apply only to \n dom inside the ShadowDOM. Polymer uses one of two techniques to imlement\n this feature.\n \n By default, rules are prefixed with the host element tag name \n as a descendant selector. This ensures styling does not leak out of the 'top'\n of the element's ShadowDOM. For example,\n\n div {\n font-weight: bold;\n }\n \n becomes:\n\n x-foo div {\n font-weight: bold;\n }\n \n becomes:\n\n\n Alternatively, if Platform.ShadowCSS.strictStyling is set to true then \n selectors are scoped by adding an attribute selector suffix to each\n simple selector that contains the host element tag name. Each element \n in the element's ShadowDOM template is also given the scope attribute. \n Thus, these rules match only elements that have the scope attribute.\n For example, given a scope name of x-foo, a rule like this:\n \n div {\n font-weight: bold;\n }\n \n becomes:\n \n div[x-foo] {\n font-weight: bold;\n }\n\n Note that elements that are dynamically added to a scope must have the scope\n selector added to them manually.\n\n * upper/lower bound encapsulation: Styles which are defined outside a\n shadowRoot should not cross the ShadowDOM boundary and should not apply\n inside a shadowRoot.\n\n This styling behavior is not emulated. Some possible ways to do this that \n were rejected due to complexity and/or performance concerns include: (1) reset\n every possible property for every possible selector for a given scope name;\n (2) re-implement css in javascript.\n \n As an alternative, users should make sure to use selectors\n specific to the scope in which they are working.\n \n * ::distributed: This behavior is not emulated. It's often not necessary\n to style the contents of a specific insertion point and instead, descendants\n of the host element can be styled selectively. Users can also create an \n extra node around an insertion point and style that node's contents\n via descendent selectors. For example, with a shadowRoot like this:\n \n <style>\n ::content(div) {\n background: red;\n }\n </style>\n <content></content>\n \n could become:\n \n <style>\n / *@polyfill .content-container div * / \n ::content(div) {\n background: red;\n }\n </style>\n <div class=\"content-container\">\n <content></content>\n </div>\n \n Note the use of @polyfill in the comment above a ShadowDOM specific style\n declaration. This is a directive to the styling shim to use the selector \n in comments in lieu of the next selector when running under polyfill.\n*/\n(function(scope) {\n\nvar ShadowCSS = {\n strictStyling: false,\n registry: {},\n // Shim styles for a given root associated with a name and extendsName\n // 1. cache root styles by name\n // 2. optionally tag root nodes with scope name\n // 3. shim polyfill directives /* @polyfill */ and /* @polyfill-rule */\n // 4. shim :host and scoping\n shimStyling: function(root, name, extendsName) {\n var scopeStyles = this.prepareRoot(root, name, extendsName);\n var typeExtension = this.isTypeExtension(extendsName);\n var scopeSelector = this.makeScopeSelector(name, typeExtension);\n // use caching to make working with styles nodes easier and to facilitate\n // lookup of extendee\n var cssText = stylesToCssText(scopeStyles, true);\n cssText = this.scopeCssText(cssText, scopeSelector);\n // cache shimmed css on root for user extensibility\n if (root) {\n root.shimmedStyle = cssText;\n }\n // add style to document\n this.addCssToDocument(cssText, name);\n },\n /*\n * Shim a style element with the given selector.

The goal is to allow users to avoid the \n most obvious pitfalls and do so without compromising performance significantly. \n For ShadowDOM styling that's not covered here, a set of best practices\n can be provided that should allow users to accomplish more complex styling.\n\n The following is a list of specific ShadowDOM styling features and a brief\n discussion of the approach used to shim.\n\n Shimmed features:\n\n * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n element using the :host rule. To shim this feature, the :host styles are \n reformatted and prefixed with a given scope name and promoted to a \n document level stylesheet.\n For example, given a scope name of .foo, a rule like this:\n \n :host {\n background: red;\n }\n }\n \n becomes:\n \n .foo {\n background: red;\n }\n \n * encapsultion: Styles defined within ShadowDOM, apply only to \n dom inside the ShadowDOM. Polymer uses one of two techniques to imlement\n this feature.\n \n By default, rules are prefixed with the host element tag name \n as a descendant selector. This ensures styling does not leak out of the 'top'\n of the element's ShadowDOM. For example,\n\n div {\n font-weight: bold;\n }\n \n becomes:\n\n x-foo div {\n font-weight: bold;\n }\n \n becomes:\n\n\n Alternatively, if Platform.ShadowCSS.strictStyling is set to true then \n selectors are scoped by adding an attribute selector suffix to each\n simple selector that contains the host element tag name. Each element \n in the element's ShadowDOM template is also given the scope attribute. \n Thus, these rules match only elements that have the scope attribute.\n For example, given a scope name of x-foo, a rule like this:\n \n div {\n font-weight: bold;\n }\n \n becomes:\n \n div[x-foo] {\n font-weight: bold;\n }\n\n Note that elements that are dynamically added to a scope must have the scope\n selector added to them manually.\n\n * upper/lower bound encapsulation: Styles which are defined outside a\n shadowRoot should not cross the ShadowDOM boundary and should not apply\n inside a shadowRoot.\n\n This styling behavior is not emulated. Some possible ways to do this that \n were rejected due to complexity and/or performance concerns include: (1) reset\n every possible property for every possible selector for a given scope name;\n (2) re-implement css in javascript.\n \n As an alternative, users should make sure to use selectors\n specific to the scope in which they are working.\n \n * ::distributed: This behavior is not emulated. It's often not necessary\n to style the contents of a specific insertion point and instead, descendants\n of the host element can be styled selectively. Users can also create an \n extra node around an insertion point and style that node's contents\n via descendent selectors. For example, with a shadowRoot like this:\n \n <style>\n ::content(div) {\n background: red;\n }\n </style>\n <content></content>\n \n could become:\n \n <style>\n / *@polyfill .content-container div * / \n ::content(div) {\n background: red;\n }\n </style>\n <div class=\"content-container\">\n <content></content>\n </div>\n \n Note the use of @polyfill in the comment above a ShadowDOM specific style\n declaration. This is a directive to the styling shim to use the selector \n in comments in lieu of the next selector when running under polyfill.\n*/\n(function(scope) {\n\nvar ShadowCSS = {\n strictStyling: false,\n registry: {},\n // Shim styles for a given root associated with a name and extendsName\n // 1. cache root styles by name\n // 2. optionally tag root nodes with scope name\n // 3. shim polyfill directives /* @polyfill */ and /* @polyfill-rule */\n // 4. shim :host and scoping\n shimStyling: function(root, name, extendsName) {\n var scopeStyles = this.prepareRoot(root, name, extendsName);\n var typeExtension = this.isTypeExtension(extendsName);\n var scopeSelector = this.makeScopeSelector(name, typeExtension);\n // use caching to make working with styles nodes easier and to facilitate\n // lookup of extendee\n var cssText = stylesToCssText(scopeStyles, true);\n cssText = this.scopeCssText(cssText, scopeSelector);\n // cache shimmed css on root for user extensibility\n if (root) {\n root.shimmedStyle = cssText;\n }\n // add style to document\n this.addCssToDocument(cssText, name);\n },\n /*\n * Shim a style element with the given selector.

+# Dart VM Service Protocol
+
+NOTE: The service api is still changing rapidly. If you use the
+service api, expect to encounter non-compatible changes.
+
+Description
+How to start
+JSON
+Websocket
+
+## Types
+
+Every response returned by the VM Service has the <code>type</code>
+property. This allows the client distinguish between different kinds
+of responses. For example, global information about the VM is encoded
+in an response of type [VM](#VM) and information about an isolate is
+encoded in an response of type [Isolate](#Isolate).
+
+If the type name of a response begins with an <code>@</code> character
+then that response is a _reference_. If the type name of a response
+does not begin with an <code>@</code> character then that response is
+an _object_ (or sometimes _full object_). A reference is meant to be
+a subset of a full object with just enough information for the client
+to generate a reasonable-looking link.
+
+For example, an isolate reference may look like this...
+
+ {
+ type: "@Isolate",
+ id: "isolates/123",
+ name: "worker"
+ }
+
+... and a full isolate object would have additional properties:
+
+ {
+ type: "Isolate",
+ id: "isolates/123",
+ name: "worker"
+ entry: ...
+ heaps: ...
+ topFrame: ...
+ ...
+ }
+
+## IDs
+
+Most responses returned by the VM Service have an <code>id</code>
+property. An id is used to request an object from the VM. Each id is
+unique; that is to say, If two responses have the same id, they refer
+to the same object. The converse is not true: the same object may
+occasionally be returned with two different ids.
+
+An id is either _global_ or _relative_. Global ids can be requested
+from the VM directly by requesting the uri <code>/{global id}</code>.
+
+The following is a list of known, fixed global ids:
+
+| id | uri | type
+| --- | --- | ---
+| vm | /vm | [VM](#VM)
+| flags | /flags | [FlagList](#FlagList)
+
+In addition, all isolates have global ids, but these ids are
+dynamically generated. An isolate with an id like
+<code>isolates/123</code> would be available at the uri
+<code>/isolates/123</code>.
+
+Relative ids are used to refer to objects that are owned by an
+isolate. Relative ids can be requested from the VM directly by
+requesting the uri <code>/{isolate id}/{relative id}</code>.
+
+For example, we can get information about a class with id
+<code>classes/Foo</code> from isolate <code>isolates/123</code> by
+requesting the uri <code>/isolates/123/classes/Foo</code> from the VM.
+
+The client must not parse ids -- they must be treated as opaque
+strings. We reserve the right to change the ids of objects.
+
+## Names
+
+Many responses have the <code>name</code> property. Names are
+provided so that objects can be displayed in a way that a Dart
+language programmer would find sensible.
+
+Note that names are not in any way unique. Many objects will have the
+same name.
+
+Occasionally responses will have the <code>vmName</code> property.
+This represents the internal names used to refer to an object inside
+the VM itself. The <code>vmName</code> of an object is only provided
+when it differs from the <code>name</code> property; when
+<code>vmName</code> is not present, the client may assume the
+<code>name</code> and <code>vmName</code> are the same.
