New Features

  • Added LegacyDataMixin to optionally use Polymer v1's behavior in handling of undefined in data bindings.
    • Intended to help larger apps transition from Polymer v1 to v3.
  • Implement opt-in strictTemplatePolicy to protect against XSS attacks with templating
    • Enabling strictTemplatePolicy by calling setStrictTemplatePolicy(true) setting causes the following changes in behavior:
      • All "self-stamping" templates including <dom-bind>, <dom-repeat>, and <dom-if> will throw errors and not stamp if not originating from inside the template of a trusted element registered via script.
      • Template retrieval from <dom-module> is disabled (since templates should be defined inline in JS via static get template() using the html tag function).
      • Legacy <dom-module> template lookup can be re-enabled via setAllowTemplateFromDomModule(true) setting; under that setting, the following additional behavior will apply:
        • Re-registration of <dom-module> will throw and cause template lookup for that element name to return null.
        • Elements that do not have templates by design must explicitly indicate a null template to prevent template retrieval from inject <dom-module>s, otherwise they will throw an error

Meaningful Changes

  • A LOT of typing improvements for both Typescript and Closure compiler
  • Add back ability to set window.Polymer.sanitizeDOMValue before Polymer loads
  • Fix data-binding notification events when the bound element has children.
  • Make sure static get properties() is only read once.
