Source code links in the docs aren't fully functional
Not all of the github source code links in the docs work as expected. Especially in ember-data docs since 3.11.
I'm having the same problem. I can only view the API docs for Ember Data 3.12 and 3.11. If I try and switch to anything lower than 3.11 I get a 404.
I was having this issue with https://api.emberjs.com/ember-data/release/classes/Model trying to view the 2.18 docs.
Thanks for reporting @jeffcressman. In 2.18 model existed in https://api.emberjs.com/ember-data/2.18/classes/DS.Model so the app broke when it couldn't find it there. Ideally it should've landed on that version's index instead of the 404 page. We'll look into this.
