Stable Release v1.2.3

• Call decorate instead of bootstrap for template prepping (commit)
• Fix global leak test. Necessary due to changes to test harness. (commit)
• Defer property application only when a custom-style is first created. (commit)
• Update comment. (commit)
• Simplify custom-style property deferment. (commit)
• [ci skip] update changelog (commit)
• Fixes #2692. Ensures that custom-style properties are applied async but before next render so that all properties are defined before any are consumed by custom-styles. Also refines dom-module's early upgrade code so that it does not affect other elements (corrects for example, custom-styles upgrading before expected). (commit)
• Remove undesired full-stop from outputs (commit)
• Fix Formatting (commit)

Stable Release v1.2.2

• use local reference for wrap. (commit)
• Add Polymer.DomApi.wrap (commit)
• For correctness, bind listeners must use a property's current value rather than its passed value. (commit)
• Explicitly making an element's _template falsy is now considered an allowable setting. This means the element stamps no content, doesn't collect any styles, and avoids looking up a dom-module. This helps address #2708 and the 5 elements Polymer registers that have no template have been set with _template: null. (commit)
• Make test work under native Shadow DOM. (commit)
• In _notifyListener, only use e.detail if the event has a detail. This is necessary for ::eventName compatibility where eventName is a native event like change. (commit)
• Fix TOC re: host event listeners. (commit)
• Fix compound bindings with braces in literals (commit)
• Re-enable listeners of the form 'a.b' (todo: make this more efficient). (commit)
• Avoid stomping on property objects when mixing behaviors. (commit)
• Update test to avoid template polypill issues. (commit)
• Ensure parent node exists when stamping. Fixes #2685. (commit)

• Weird assignment fix (commit)
• add comment. (commit)
• For efficiency, use cached events in data system, for property and path changes. (commit)
• Fixes #2690 (commit)
• change after render method to Polymer.RenderStatus.afterNextRender (commit)
• When effect values are applied via bindings, use fromAbove gambit to avoid unnecessary wheel spinning. (This is now possible since we have fast lookup for readOnly where we want to avoid doing the set at all). (commit)
• do readOnly check for configured properties where they are handed down, rather than when they are consumed. (commit)
• Minor cleanup. (commit)
• Avoid creating unnecessary placeholders for full refresh. (commit)
• Simplify (commit)
• Fix typo. (commit)
• Update docs. (commit)
• _removeInstance -> _detachAndRemoveInstance (commit)
• Remove limit & chunkCount API. Refactor insert/remove. (commit)
• add back deepContains (got removed incorrectly in merge). (commit)
• fix line endings. (commit)
• revert host attributes ordering change optimization as it was not worth the trouble (barely measurable and more cumbersome impl). (commit)
• rename host functions fix typos afterFirstRender is now raf+setTimeout dom-repeat: remove cruft (commit)
• Fix Gestures when using SD polyfill (commit)
• Fix for multiple consequent spaces present in CSS selectors, fixes #2670 (commit)
• avoid configuration work when unnecessary (commit)
• lazily create effect objects so we can more easily abort processing. avoid forEach (commit)
• provides support for memoizing pathFn on effect; only process effects/listeners if they exist. (commit)

• Avoid using .slice and .forEach (commit)
• Added support for short unicode escape sequences, fixes #2650 (commit)
• Fix for BEM-like CSS selectors under media queries, fixes #2639. Small optimization for produced CSS (empty rules produced semicolon before, now empty string). (commit)

• Add notes on running unit tests. (commit)
• Corrected method name. Fixes #2649. (commit)
• Fix typos in more efficient array copying. (commit)
• Adds Polymer.RenderStatus.afterFirstRender method. Call to perform tasks after an element first renders. (commit)
• More efficient array management in Polymer.DomApi. (commit)
• Fixes #2652 (commit)
• [ci skip] update changelog (commit)
• Fix whitespace around bindings. (commit)
• Add support for strip-whitespace. Should fix #2511. (commit)
• Improve efficiency of attribute configuration. (commit)
• Remove use of Function.bind (commit)
• fix typos. (commit)
• Re-use data change events. Remove unused/undocumented listener object specific node listening feature. (commit)

• Add Polymer.dom.deepContains (commit)
• [ci skip] Update CHANGELOG (commit)
• isLightDescendant should return false for self (commit)
• Fix for mixins declaration with space before colon. Allow any space character or even { and } (before and after capturing pattern correspondingly) as pattern boundaries instead of new lines only. In minified sources there might be no space, semicolon or line start, so we need to account that as well. (commit)

Stable Release v1.2.0

• A simpler travis config (commit)
• Fix #2587: When Polymer.dom(el).appendChild(node) is called, cleanup work must be performed on the existing parent of node. This change fixes a missing case in this cleanup work: if the existing parent has a observer via Polymer.dom(parent).observeNodes, it needs to be notified that node is being removed even if the node does not have specific logical info. For example, if an observed node has no Shady DOM and has a child that is removed. A test for this case was added. (commit)

v1.1.2

• Improve composed parent tracking. (commit)
• move the mixing-in of behaviors so that it happens before register behaviors are invoked (commit)
• Fixes #2378 (commit)
• Fixes #2356: issue a warning and don't throw an exception when a style include cannot be found. Fixes #2357: include data now comes before any textContent in a style element. (commit)
• remove unneeded protection code for extends. (commit)
• Add test (commit)
• add test for registered behavior affecting a value then used by features (commit)
• add tests for new Polymer() argument support (and make Base tests aware of new abstract method _desugarBehaviors) (commit)
• invoke registration behavior before registering features, so behaviors can alter features, this requires calling behavior flattening as part of prototype desugaring instead of as part of behavior prep, so the flattened list is available early (commit)
• do registered behaviors before invoking registerFeatures so registered can affect properties used by features (ref #2329) (commit)

• Fixes #2334: when composing nodes in shady dom, check if a node is where we expect it to be before removing it from its distributed position. We do this because the node may have been moved by Polymer.dom in a way that triggered distribution of its previous location. The node is already where it needs to be so removing it from its parent when it's no longer distributed is destructive. (commit)
• use cached template annotations when possible (commit)
• fix comment typos (commit)
• Update changelog with v1.1.1 release (commit)

v1.1.1

• Fixes #2263: ensure custom-style can parse variable definitions in supported selectors (e.g. /deep/) without exception due to unknown css. (commit)

• Fixes #2276: avoid losing logical information and simplify logical tree handling (commit)
• Moved check earlier. Added test for negative literal. (commit)
• Fixes #2253: refine logical tree check and populate parents of insertion points with logical info only if necessary. Fixes #2283: when a node is removed, we need to potentially distribute not only its host but also its parent. (commit)
• Support for negative numbers in computed bindings (commit)

v1.1.0

• Add comment. (commit)
• Add tests for key splice fix. (commit)

• Document custom-style module property. (commit)

• don-module no longer needs to eagerly upgrade custom elements since the web components polyfills do this automatically. (commit)
