Big Changes

  • [New Feature] ::content works standalone when styling (used to require something in front, like ::host)

  • Attributes bound that are not in the properties block will not make a property (previously, a property would be made, but not kept up to date with the attribute changing)

  • [New Feature] Newlines now supported in computed bindings

    • Example
    <div hidden$="[[_someVeryLongFunctionName(
                someVeryLongArg,
                anotherCrazyLongArg)]]">

  • [New Feature] CSS Custom properties now work in @keyframe rules

  • Polymer is now using ESLint

  • [New Feature] Allow [attribute ~= "value"] selectors

  • Equalize styling specificity of CSS Custom Properties and ::host rules

  • Deduplicate behaviors (prevent weird behaviors when multiple behaviors try to override each other because they are duplicated).

  • [New Feature] Bindings of style {{ foo.bar-baz }} now work

  • CSS Variables with values that contain parens like url() now work

  • [New Feature] Add support for dynamic functions in bindings

    • computedBindings and observers will trigger when a function changes
    • computedBindings on functions can be used to lazily trigger bindings on external changes, or encapsulate dependencies
    • A good example is a translate function for i18n that depends on external translation tables
    • Example
    <i18n-string>[[translate('hi!')]]</i18n-string>
<script>
Polymer({
  is: 'i18n-string',
  properties: {
    translate: {
      type: Function,
      computed: '_computeTranslateFn(translationService)'
    },
    translationService: {
      type: Function,
      value: function(str){ return str; }
    }
  },
  _computeTranslateFn: function(ts) {
    return function(str) {
      return ts(str);
    }
  }
});
</script>

    In this example, i18n-string can wait for translationService to be set before attempting translations, will update translations when translationService is changed, and encapsulates the dependency on translationService in the computed translate function, removing it from the binding.

  • Setting properties on un-upgraded elements is now supported.

    • Properties will be pushed into the data binding system when the element upgrades.
