  silently failing).
* [BUGFIX] Fix deprecated bindAttr helper.
* [BUGFIX] Do not allow both keyword and block params.
* Cleanup HTMLBars public API
  * Remove `Ember.HTMLBars.helper`.
  * Remove internal `registerBoundHelper` function (use

* [BUILD TOOLING] Enable easier cross-browser testing by publishing builds and tests to S3.
