Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[0.9.0] - 2018-02-01

  • Refactored how template tags and render() are implemented so that all specialization of template syntax is done in tags, not render(), allowing for the mixining of templates of different syntaxes, and for hooks in render() to change templates before they're initially processed.
  • Added ShadyCSS support in lib/shady-render.js. It's exported render function will pass templates to ShadyCSS's prepareTemplate() function to process style tags and elements in the template for emulate CSS scoping.
  • lit-extended: Attribute bindings with a ? suffix on the name now act as boolean attributes. The attribute will be removed for falsey values and set to '' for truthy values, matching the HTML specification behavior for boolean attributes.
  • Fixed a bug where directives rendered incorrectly on AttributeParts and PropertyParts

  • Allow all valid HTML attribute names, including emoji and Angular-style (foo)= and [foo]= names.
  • Drastically improved performance of the repeat directive.
  • Fixed an issue with expressions directly following elements.
  • Fixed numerous bugs with the repeat directive.
  • Performance improvements for template setup
  • Internal code cleanup
  • Support synchronous thenables

[0.7.0] - 2017-10-06
