v3.4.0 (2020-04-23)

New global settings

This update to Polymer includes some new global settings:

legacyUndefined / setLegacyUndefined

What does it do? This setting reverts how computed properties handle undefined values to the Polymer 1 behavior: when enabled, computed properties will only be recomputed if none of their dependencies are undefined.

Components can override the global setting by setting their _overrideLegacyUndefined property to true. This is useful for reenabling the default behavior as you migrate individual components:
```
import {PolymerElement, html} from '@polymer/polymer/polymer-element.js';

class MigratedElement extends PolymerElement { /* ... */ }

// All MigratedElement instances will use the default behavior.
MigratedElement.prototype._overrideLegacyUndefined = true;

customElements.define('migrated-element', SomeElement);
```
Should I use it? This setting should only be used for migrating legacy codebases that depend on this behavior and is otherwise not recommended.
legacyWarnings / setLegacyWarnings

What does it do? This setting causes Polymer to warn if a component's template contains bindings to properties that are not listed in that element's properties block. For example:
```
import {PolymerElement, html} from '@polymer/polymer/polymer-element.js';

class SomeElement extends PolymerElement {
  static get template() {
    return html`<span>[[someProperty]] is used here</span>`;
  }

  static get properties() {
    return { /* but `someProperty` is not declared here */ };
  }
}

customElements.define('some-element', SomeElement);
```
Only properties explicitly declared in the properties block are associated with an attribute and update when that attribute changes. Enabling this setting will show you where you might have forgotten to declare properties.

Should I use it? Consider using this feature during development but don't enable it in production.
orderedComputed / setOrderedComputed

What does it do? This setting causes Polymer to topologically sort each component's computed properties graph when the class is initialized and uses that order whenever computed properties are run.

For example:
```
import {PolymerElement, html} from '@polymer/polymer/polymer-element.js';

class SomeElement extends PolymerElement {
  static get properties() {
    return {
      a: {type: Number, value: 0},
      b: {type: Number, computed: 'computeB(a)'},
      c: {type: Number, computed: 'computeC(a, b)'},
    };
  }

  computeB(a) {
    console.log('Computing b...');
    return a + 1;
  }

  computeC(a, b) {
    console.log('Computing c...');
    return (a + b) * 2;
  }
}

customElements.define('some-element', SomeElement);
```
When a changes, Polymer's default behavior does not specify the order in which its dependents will run. Given that both b and c depend directly on a, one of two possible orders could occur: [computeB, computeC] or [computeC, computeB].
- In the first case - [computeB, computeC] - computeB is run with the new value of a and produces a new value for b. Then, computeC is run with both the new values of a and b to produce c.
- In the second case - [computeC, computeB] - computeC is run first with the new value of a and the current value of b to produce c. Then, computeB is run with the new value of a to produce b. If computeB changed the value of b then computeC will be run again, with the new values of both a and b to produce the final value of c.
However, with orderedComputed enabled, the computed properties would have been previously sorted into [computeB, computeC], so updating a would cause them to run specifically in that order.

If your component's computed property graph contains cycles, the order in which they are run when using orderedComputed is still undefined.

Should I use it? The value of this setting depends on how your computed property functions are implemented. If they are pure and relatively inexpensive, you shouldn't need to enable this feature. If they have side effects that would make the order in which they are run important or are expensive enough that it would be a problem to run them multiple times for a property update, consider enabling it.
fastDomIf / setFastDomIf

What does it do? This setting enables a different implementation of <dom-if> that uses its host element's template stamping facilities (provided as part of PolymerElement) rather than including its own. This setting can help with performance but comes with a few caveats:
- First, fastDomIf requires that every <dom-if> is in the shadow root of a Polymer element: you can't use a <dom-if> directly in the main document or inside a shadow root of an element that doesn't extend PolymerElement.
- Second, because the fastDomIf implementation of <dom-if> doesn't include its own template stamping features, it doesn't create its own scope for property effects. This means that any properties you were previously setting on the <dom-if> will no longer be applied within its template, only properties of the host element are available.
Should I use it? This setting is recommended as long as your app doesn't use <dom-if> as described in the section above.
removeNestedTemplates / setRemoveNestedTemplates

What does it do? This setting causes Polymer to remove the child <template> elements used by <dom-if> and <dom-repeat> from the their containing templates. This can improve the performance of cloning your component's template when new instances are created.

Should I use it? This setting is generally recommended.

suppressTemplateNotifications / setSuppressTemplateNotifications

What does it do? This setting causes <dom-if> and <dom-repeat> not to dispatch dom-change events when their rendered content is updated. If you're using lots of <dom-if> and <dom-repeat> but not listening for these events, this setting lets you disable them and their associated dispatch work.

You can override the global setting for an individual <dom-if> or <dom-repeat> by setting its notify-dom-change boolean attribute:

import {PolymerElement, html} from '@polymer/polymer/polymer-element.js';

class SomeElement extends PolymerElement {
  static get properties() {
    return {
      visible: {type: Boolean, value: false},
    };
  }

  static get template() {
    return html`
      <button on-click="_toggle">Toggle</button>
      <!-- Set notify-dom-change to enable dom-change events for this particular <dom-if>. -->
      <dom-if if="[[visible]]" notify-dom-change on-dom-change="_onDomChange">
        <template>
          Hello!
        </template>
      </dom-if>
    `;
  }

  _toggle() {
    this.visible = !this.visible;
  }

  _onDomChange(e) {
    console.log("Received 'dom-change' event.");
  }
}

customElements.define('some-element', SomeElement);

Should I use it? This setting is generally recommended.

legacyNoObservedAttributes / setLegacyNoObservedAttributes

What does it do? This setting causes LegacyElementMixin not to use the browser's built-in mechanism for informing elements of attribute changes (i.e. observedAttributes and attributeChangedCallback), which lets Polymer skip computing the list of attributes it tells the browser to observe. Instead, LegacyElementMixin simulates this behavior by overriding attribute APIs on the element and calling attributeChangedCallback itself.

This setting has similar API restrictions to those of the custom elements polyfill. You should only use the element's setAttribute and removeAttribute methods to modify attributes: using (e.g.) the element's attributes property to modify its attributes is not supported with legacyNoObservedAttributes and won't properly trigger attributeChangedCallback or any property effects.

Components can override the global setting by setting their _legacyForceObservedAttributes property to true. This property's effects occur at startup; it won't have any effect if modified at runtime and should be set in the class definition.

Should I use it? This setting should only be used if startup time is significantly affected by Polymer's class initialization work - for example, if you have a large number of components being loaded but are only instantiating a small subset of them. Otherwise, this setting is not recommended.
useAdoptedStyleSheetsWithBuiltCSS / setUseAdoptedStyleSheetsWithBuiltCSS

What does it do? If your application is uses pre-built Shady CSS styles and your browser supports constructable stylesheet objects, this setting will cause Polymer to extract all <style> elements from your components' templates, join them into a single stylesheet, and share this stylesheet with all instances of the component using their shadow roots' adoptedStyleSheets array. This setting may improve your components' memory usage and performance depending on how many instances you create and how large their style sheets are.

Should I use it? Consider using this setting if your app already uses pre-built Shady CSS styles. Note that position-dependent CSS selectors (e.g. containing :nth-child()) may become unreliable for siblings of your components' styles as a result of runtime-detected browser support determining if styles are removed from your components' shadow roots.

Other new features

`<dom-repeat>`

reuseChunkedInstances

What does it do? This boolean property causes <dom-repeat> to reuse template instances even when items is replaced with a new array, matching the Polymer 1 behavior.

By default, a <dom-repeat> with chunking enabled (i.e. initialCount >= 0) will drop all previously rendered template instances and create new ones whenever the items array is replaced. With reuseChunkedInstances set, any previously rendered template instances will instead be repopulated with data from the new array before new instances are created.

Should I use it? This flag is generally recommended and can improve rendering performance of chunked <dom-repeat> instances with live data.

`LegacyElementMixin`

disable-upgrade

What does it do? LegacyElementMixin now has built-in support for the disable-upgrade attribute (usually provided by DisableUpgradeMixin) that becomes active when the global legacyOptimizations setting is enabled, matching the Polymer 1 behavior.

Should I use it? Consider using this setting if you are already using the legacyOptimizations setting and migrating older components that depend on disable-upgrade without explicit application of DisableUpgradeMixin.

Bug fixes

`<dom-repeat>`

Chunking behavior

<dom-repeat> no longer resets the number of rendered instances to initialCount when modifying items with PolymerElement's array modification methods (splice, push, etc.). The number of rendered instances will only be reset to initialCount if the items array itself is replaced with a new array object.

See #5631 for more information.

Update Sauce config to drop Safari 9, add 12 & 13. Safari 9 is now very old, and has micro task ordering bugs issues that make testing flaky. (commit)
Remove accidental commit of test.only (commit)
When re-enabling, ensure __limit is at a good starting point and add a test for that. Also: * Ensure __itemsArrayChanged is cleared after every render. * Enqueue __continueChunkingAfterRaf before notifying renderedItemCount for safety (commit)
Remove accidental commit of suite.only (commit)
Ensure limit is reset when initialCount is disabled. Note that any falsey value for initialCount (including 0) is interpreted as "chunking disabled". This is consistent with 1.x logic, and follows from the logic of "starting chunking by rendering zero items" doesn't really make sense. (commit)
Updates from review. * Refactoring __render for readability * Removing __pool; this was never used in v2: since we reset the pool every update and items are only ever pushed at detach time and we only detach at the end of updates (as opposed to v1 which had more sophisticated splicing) (commit)
Store syncInfo on the dom-if, but null it in teardown. (same as invalidProps for non-fastDomIf) (commit)
Fixes for several related dom-repeat chunking issues. Fixes #5631. * Only restart chunking (resetting the list to the initialCount) if the items array itself changed (and not splices to the array), to match Polymer 1 behavior. * Add reuseChunkedInstances option to allow reusing instances even when items changes; this is likely the more common optimal case when using immutable data, but making it optional for backward compatibility. * Only measure render time and throttle the chunk size if we rendered a full chunk of new items. Ensures that fast re-renders of existing items don't cause the chunk size to scale up dramatically, subsequently causing too many new items to be created in one chunk. * Increase the limit by the chunk size as part of any render if there are new items to render, rather than only as a result of rendering. * Continue chunking by comparing the filtered item count to the limit (not the unfiltered item count).

[ci-skip] Add comment explaining confusing check in _addPropertyToAttributeMap (commit)
Ensure clients are flushed when runtime stamping via _stampTemplate. Maintains flush semantics with Templatizer stamping (relevant to fastDomIf, which is a switch between Templatizer-based stamping and runtime _stampTemplate-based stamping). Works around an issue with noPatch where nested undistributed dom-if's won't stamp. The changes to the tests are to remove testing that the full host tree is correct since the host doing the runtime stamping will no longer be the DOM getRootNode().host at ready time (this is exactly the case with Templatizer, whose semantics we intend to match). (commit)
Fix template-finding issue with DisableUpgrade mixin. The existing rules are that prototype._template is first priority and dom-module via is is second priority for a given class. A subclass has a new shot at overriding the previous template either by defining a new prototype._template or a new is resulting in a dom-module lookup. However, trivially subclassing a Polymer legacy element breaks these rules, since if there is no own prototype._template on the current class, it will lookup a dom-module using is from up the entire prototype chain. This defeats the rule that a prototype._template on the superclass should have taken priority over its dom-module. This change ensures that we only lookup dom-module if the class has an own is property. (commit)

Attempt to sync host properties on every call to _showHideChildren.

Improve comment more (commit)
Improve comment (commit)
Add comment. (commit)
- Improve clarity: change __dataInitialized to __dataReady * When _flushClients is called, ensure that clients are always enabled or flushed as appropriate. This ensures that (1) clients that are enabled before the host is enabled flush properly, and (2) clients that are stamped but not enabled properly enable when the host flushes. (commit)
Fix typo in runBindingEffect documentation (commit)
Fixes #4601. Client elements can be readied that have already enabled properties. This can happen when templatize is used to create instances with no properties. In this case, in order for properties to flush properly to clients, clients must be flushed. (commit)

[ci skip] Add back intro README content from 1.x, updated to 2.x syntax. (commit)

v2.0.0-rc.1 (2017-03-06)

The following notable changes have been made since the 2.0 Preview announcement.

The config getter on element classes has been replaced by individual properties and observers getters, more closely resembling the 1.x syntax.

static get properties() {
  return {
    aProp: String,
    bProp: Number
  }
}
static get observers() {
  return [
    '_observeStuff(aProp,bProp)'
  ]
}

1.x-style dirty checking has been reinstated for better performance. An optional mixin is available for elements to skip dirty checking of objects and arrays, which may be more easy to integrate with some state management systems. For details, see Using the MutableData mixin in Data system concepts.
Support for dynamically-created custom-style elements has been added.
Support for the external style sheet syntax, <link rel="import" type="css"> has been added. This was deprecated in 1.x, but will be retained until an alternate solution is available for importing unprocessed CSS.
New properties rootPath and basePath were added to Polymer.Element to allow authors to configure how URLs are rewritten inside templates. For details, see the Update URLs in templates in the Upgrade guide.

[ci skip] Update comment to include reference to problem browser. (commit)
Check documentElement instead of body to guarantee it's there. (commit)
add tests (commit)
Adds a setting preserveStyleIncludes which, when used with a shadow dom targeted css build and native custom properties, will copy styles into the Shadow DOM template rather than collapsing them into a single style. This will (1) allow the browser to optimize parsing of shared styles because they remain intact, (2) reduce the size of the css build resources when shared styles are used since they are not pre-collapsed. This option does perform registration runtime work to add included styles to element templates. (commit)
Fix test failures by feature detecting instance properties accessors. Can't rely on __proto__ on IE10, but that browser doesn't need to avoid properties. (commit)
Read properties off of proto during configuration. (commit)

Test positive case of suppressBindingNotifications (commit)
Add notifyDomBind to dom-bind. (commit)
Test Polymer.Settings inside test. (commit)
Revert unnecessary change. (commit)
Fix test lint issue. (commit)
Add global flags to suppress unnecessary notification events. Fixes #4262. * Polymer.Settings.suppressTemplateNotifications - disables dom-change and rendered-item-count events from dom-if, dom-repeat, and don-bind. Users can opt back into dom-change events by setting the notify-dom-change attribute (notifyDomChange: true property) to dom-if/don-repeat instances. * Polymer.Settings.suppressBindingNotifications - disables notify effects when propagating data downward via bindings. Generally these are never useful unless users are explicitly doing something like <my-el foo="{{foo}} on-foo-changed="{{handleFoo}}"> or calling addEventListener('foo-changed', ...) on an element where foo is bound (we attempted to make this the default some time back but needed to revert it when we found via #3077 that users were indeed doing this). Users that avoid these patterns can enjoy the potentially significant benefit of suppressing unnecessary events during downward data flow by opting into this flag. (commit)
Fix strip-whitespace for nested templates. (commit)

Missing piece to fixing #3094 (commit)
Opt in to "even lazier" behavior by setting lazyRegister to "max". This was done to preserve compatibility with the existing feature. Specifically, when "max" is used, setting is in beforeRegister and defining factoryImpl may only be done on an element's prototype and not its behaviors. In addition, the element's beforeRegister is called before its behaviors' beforeRegisters rather than after as in the normal case. (commit)

remove unneeded argument (commit)
slight optimization, avoid work if no cssText is set. (commit)
More efficient fix for #3661. Re-uses cached style element that needs to be replaced in the document rather than creating a new one. (commit)
Fixes #3661: ensure that cached style points to the applied style for Shady DOM styling. This ensures that the cache can be used to determine if a style needs to be applied to the document and prevents extra unnecessary styles from being added. This could happen when a property cascaded to a nested element and updateStyles was called after properties have changed. (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.

Remove undesired full-stop from outputs (commit)

v1.2.2 (2015-11-12)

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)

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)

Minor cleanup. (commit)
Avoid creating unnecessary placeholders for full refresh. (commit)

Avoid using .slice and .forEach (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)

v1.2.0 (2015-10-22)

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 (2015-08-28)

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)
specifically create Polymer object on window to satisfy strict mode (fixes #2363) (commit)
Remove forceUpgraded check in dom-module.import (commit)
Fixes #2341: branch Polymer.dom to use native dom methods under Shadow DOM for: appendChild, insertBefore, removeChild, replaceChild, cloneNode. (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 (2015-08-20)

Fixes #2263: ensure custom-style can parse variable definitions in supported selectors (e.g. /deep/) without exception due to unknown css. (commit)
Fixes #2311, #2323: when elements are removed from their previous position when they are added elsewhere, make sure to remove them from composed, not logical parent. (commit)
Update Changelog (commit)
Add selectedItem property (commit)
Add test for large splice (commit)
Use numeric sort when removing dom-repeat instances (commit)
Fixes #2267: properly find dom-module for mixed case elements (commit)

Avoid saving logical info on parent when a content is added inside a fragment + slight factoring. (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 (2015-08-13)

Add comment. (commit)
Add tests for key splice fix. (commit)
Fixes #2251: resolve imported stylesheets against correct document. (commit)
Reduce keySplices to minimum change set before notifying. Fixes #2261 (commit)
Make clearSelection public. (commit)
Add logical info iff an element being added is an insertion point; do not add logical info for any element in a shady root. (commit)
Make clearSelection public. (commit)
Fixes #2235. Manages logical information in shady distribution more directly by capturing it explicitly when needed and not whenever distribution is run. (commit)

Based on feedback, change module to include in custom-style and dom-module style marshaling. (commit)
Document custom-style module property. (commit)
Add comment. (commit)
Add tests and require module to be on style elements. (commit)
custom-style supports module property that accepts a dom-module containing style data. don-module style data may be specified inside <template> elements and style elements also support module attribute for referencing additional modules containing style data. (commit)
don-module no longer needs to eagerly upgrade custom elements since the web components polyfills do this automatically. (commit)
