In the release notes for Ember 1.10.0 (Ember.js 1.10.0 and 1.11 Beta Released) there is mention that one should remove the Handlebars dependency since the runtime dependency for HTMLbars is now built into the framework.
When I remove handlebars from bower.json and then delete bower_components/handlebars, my app no longer builds, and instead receives the following error:
Path or pattern "bower_components/handlebars/handlebars.js" did not match any files

If I keep handlebars in bower.json then everything seems to work just fine and I can use the new htmlbars syntax such as block param.
