#16485, but targeted against master

Thank you!

I've pulled these changes into the beta and release branches, you should be able to use the latest release / beta builds once CI is completed and the changes should be included in the next release of each branch...

you should be able to use the latest release / beta builds

@rwjblue is there a good place to find these or can we point package.json at 'emberjs/ember.js#release'?

Turns out that I didn't have a good way to explain this, so I just made it simpler (in ember-cli/ember-source-channel-url#2).

This should be all you need to do to get the URL to put in your package.json:

npm install -g ember-source-channel-url
ember-source-channel-url release

That will print out the current URL for that channel, and you can put that directly in your package.json like:

//...snip...
"ember-source": "<URL GOES HERE>",
//...snip...

Nice! I’ll try to see if there is a way to better document this in the ember repo.
