+## 0.1.0
+
+* Remove `Server.handleRequest()` and `Server.parseRequest()`. Instead, `new
+  Server()` takes a `Stream` and a `StreamSink` and uses those behind-the-scenes
+  for its communication.
+
+* Add `Server.listen()`, which causes the server to begin listening to the
+  underlying request stream.
+
+* Add `Server.close()`, which closes the underlying request stream and response

 ## 0.0.2+3

On the other, grouping upgrades into a single task means less\n    incremental work (for example style recalcs),  Also, we can ensure the \n    document is in a known state at the single quantum of time when \n    elements upgrade.\n\n  */\n  var queue = {\n    // tell the queue to wait for an element to be ready\n    wait: function(element, check, go) {\n      var shouldAdd = (this.indexOf(element) === -1 && \n          flushQueue.indexOf(element) === -1);\n      if (shouldAdd) {\n        this.add(element);\n        element.__check = check;\n        element.__go = go;\n      }\n      return (this.indexOf(element) !== 0);\n    },\n    add: function(element) {\n      //console.log('queueing', element.name);\n      queueForElement(element).push(element);\n    },\n    indexOf: function(element) {\n      var i = queueForElement(element).indexOf(element);\n      if (i >= 0 && document.contains(element)) {\n        i += (HTMLImports.useNative || HTMLImports.ready) ? \n          importQueue.length : 1e9;\n      }\n      return i;  \n    },\n    // tell the queue an element is ready to be registered\n    go: function(element) {\n      var readied = this.remove(element);\n      if (readied) {\n        this.addToFlushQueue(readied);\n        this.check();\n      }\n    },\n    remove: function(element) {\n      var i = this.indexOf(element);\n      if (i !== 0) {\n        //console.warn('queue order wrong', i);\n        return;\n      }\n      return queueForElement(element).shift();\n    },\n    check: function() {\n      // next\n      var element = this.nextElement();\n      if (element) {\n        element.__check.call(element);\n      }\n      if (this.canReady()) {\n        this.ready();\n        return true;\n      }\n    },\n    nextElement: function() {\n      return nextQueued();\n    },\n    canReady: function() {\n      return !this.waitToReady && this.isEmpty();\n    },\n    isEmpty: function() {\n      return !importQueue.length && !mainQueue.length;\n    },\n    addToFlushQueue: function(element) {\n      flushQueue.push(element);  \n    },\n    flush: function() {\n      var element;\n      while (flushQueue.length) {\n        element = flushQueue.shift();\n        element.__go.call(element);\n        element.__check = element.__go = null;\n      }\n    },\n    ready: function() {\n      this.flush();\n      // TODO(sorvell): As an optimization, turn off CE polyfill upgrading\n      // while registering.

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.

+## 1.1.1
+
+* Fix broken type arguments that caused breakage on dart2js.
+
+* Fix an analyzer warning in `yaml_node_wrapper.dart`.
+
+## 1.1.0
+
+* Add new publicly-accessible constructors for `YamlNode` subclasses. These
+  constructors make it possible to use the same API to access non-YAML data as
+  YAML data.
+
+* Make `YamlException` inherit from source_map's [`SpanFormatException`][]. This
+  improves the error formatting and allows callers access to source range
+  information.
+
+[SpanFormatException]: (http://www.dartdocs.org/documentation/source_maps/0.9.2/index.html#source_maps/source_maps.SpanFormatException)
+
 ## 1.0.0+1
 
 * Fix a variable name typo.

-  This is a limited shim for ShadowDOM css styling.
-  https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#styles
-  
-  The intention here is to support only the styling features which can be 
-  relatively simply implemented. The goal is to allow users to avoid the 
-  most obvious pitfalls and do so without compromising performance significantly. 
-  For ShadowDOM styling that's not covered here, a set of best practices
-  can be provided that should allow users to accomplish more complex styling.
-
-  The following is a list of specific ShadowDOM styling features and a brief
-  discussion of the approach used to shim.
-
-  Shimmed features:
-
-  * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host
-  element using the :host rule. To shim this feature, the :host styles are 
-  reformatted and prefixed with a given scope name and promoted to a 
-  document level stylesheet.
-  For example, given a scope name of .foo, a rule like this:
-  
-    :host {
-        background: red;
-      }
-    }
-  
-  becomes:
-  
-    .foo {
-      background: red;
-    }
-  
-  * encapsultion: Styles defined within ShadowDOM, apply only to 
-  dom inside the ShadowDOM. Polymer uses one of two techniques to imlement
-  this feature.
-  
-  By default, rules are prefixed with the host element tag name 
-  as a descendant selector. This ensures styling does not leak out of the 'top'
-  of the element's ShadowDOM. For example,
-
-  div {
-      font-weight: bold;
-    }
-  
-  becomes:
-
-  x-foo div {
-      font-weight: bold;
-    }
-  
-  becomes:
-
-
-  Alternatively, if Platform.ShadowCSS.strictStyling is set to true then 
-  selectors are scoped by adding an attribute selector suffix to each
-  simple selector that contains the host element tag name. Each element 
-  in the element's ShadowDOM template is also given the scope attribute. 
-  Thus, these rules match only elements that have the scope attribute.
-  For example, given a scope name of x-foo, a rule like this:
-  
-    div {
-      font-weight: bold;
-    }
-  
-  becomes:
-  
-    div[x-foo] {
-      font-weight: bold;
-    }
-
-  Note that elements that are dynamically added to a scope must have the scope
-  selector added to them manually.
-
-  * upper/lower bound encapsulation: Styles which are defined outside a
-  shadowRoot should not cross the ShadowDOM boundary and should not apply
-  inside a shadowRoot.
-
-  This styling behavior is not emulated. Some possible ways to do this that 
-  were rejected due to complexity and/or performance concerns include: (1) reset
-  every possible property for every possible selector for a given scope name;
-  (2) re-implement css in javascript.
-  
-  As an alternative, users should make sure to use selectors
-  specific to the scope in which they are working.
-  
-  * ::distributed: This behavior is not emulated. It's often not necessary
-  to style the contents of a specific insertion point and instead, descendants
-  of the host element can be styled selectively. Users can also create an 
-  extra node around an insertion point and style that node's contents
-  via descendent selectors. For example, with a shadowRoot like this:
-  
-    <style>
-      ::content(div) {
-        background: red;
-      }
-    </style>
-    <content></content>
-  
-  could become:
-  
-    <style>
-      / *@polyfill .content-container div * / 
-      ::content(div) {
-        background: red;
-      }
-    </style>
-    <div class="content-container">
-      <content></content>
-    </div>
-  
-  Note the use of @polyfill in the comment above a ShadowDOM specific style
-  declaration. This is a directive to the styling shim to use the selector 
-  in comments in lieu of the next selector when running under polyfill.

+// to its incoming blocks and that's why the "state = state0" assignment ended
+// up just before the condition.
+// Note that the assignment was executed at every iteration instead of just
+// when exiting the loop.
