Stable release 2013-10-03

General changes

• Polymer's FOUC prevention - Polymer's FOUC prevention is now customizable through polymer-veiled and polymer-unveil classes. To veil (initially hide) an element either include the polymer-veiled class on the element or add to the array: Polymer.veiledElements. This list includes body by default but that can be removed to prevent body from getting de-fuoc'd. Note: Polymer automatically unveils elements at WebComponentsReady time, but elements can be dynamically unveiled by (1) adding the polymer-veiled class to hide them and (2) when they are ready, calling Polymer.unveilElements().
• Souremaps should now be fixed. (commit). Please holler if you see otherwise.
• Removed deprecated Polymer.register() (commit)
• lightdom attribute on <polymer-element> for producing light dom instead of shadow dom.

CustomElements

• Refine boot logic to address #68 (commit)
• Defer entered/leftView() on platforms without MutationObserver (IE) to make polyfill less flaky. (commit)
• Avoid using native implementation when document.webkitRegister is available. It's outdated and no longer spec compliant. (commit)
• enterView/leaveView() callbacks to apply only to primary document. (commit)

HTMLImports

• Expose HTMLImports.ready flag (commit)
• Avoid using readyState interactive in IE. (commit)
• HTMLImports polyfill can be loaded asynchronously (commit)
• Added IE9 support (commit)

NodeBind

• Fix for using radio buttons (commit)

PointerEvents

• Support Blink's touch-action-delay property (commit)

ShadowDOM

• Fixes with syncing render nodes (commit)
• Call nodeWasAdded() on all the nodes in the added tree. (commit)
• Change from using a WeakMap to use expando (commit)

TemplateBinding

• Fixed #285. Bindings in nested templates with named scopes fail to update correctly after initial population (commit)

labs

• Lots of work on the contacts and shuttle demo apps.
• x-tags experiments (commit)
• Brick + Polymer experiments (commit)
• Add --inline flag to Vulcanizer - inline all scripts into main document (opposite of --csp) (commit)
• gs-app: a wip app for getting started (commit)
• <css-to-webanimations-el> - create web animations code from CSS animations (commit)

observe-js

• Include observed array as forth callback arg for non-valueFn CompoundPathObserver. (commit)

platform

• make shimmed styles available on root for extensibility. (commit)
• Removed {NodeList,NamedNodeMap,HTMLCollection}.forEach, use .array() instead (commit)
• Souremaps have been fixed. (commit)

polymer

• support stamping template into lightDOM instead of ShadowDOM when polymer-element has lightdom attribute (Issue #222) (commit)
• User attributes are not overriden with instance attributes (ref #190) (commit)
• coalesce all desugaring and call it before user registerCallback extension point (commit)
• Generalize Polymer's FOUC prevention strategy; Fixes #276. (commit)
• Fixed #298 - <propertyName>Changed() may get called twice for a single property value change (commit)
• Removed deprecated.js entirely (commit)
• Removed deprecated Polymer.register (commit)
• Faster node collection iteration. (commit)
• ensure super works on prototype challenged platforms (IE). This ensures we find Element.bind via super. (commit)
• Optimized iterations by caching keylist for publish and observe maps (commit)
• defer all create-time preparation work if we have no defaultView unless forceReady flag is set. Otherwise perform this work at enteredDocument time. This is a stand in for an ownerDocumentChangedCallback. (commit)
