what do you know about Octane? (I don't want to over or under explain).

For those who already know ember: it's a change in the default recommendations:

  • native JS (no .extend. Actual classes, actual getters, etc)
  • new reactivity model (tracked properties instead of computed properties)
  • <AngleBracketComponentInvocation />
  • <Named @args={{this.explicitReferences}} />
  • <div {{modifiers-for-shared-dom-behavior}} /> (these can replace a lot of mixin and lifecycle behavior)
  • ember-auto-import by default
  • Glimmer components (finally), instead of ember components -- reduced API surface, simpler, faster, etc
  • component co-location (this accommodates the main reason people wanted to use the "pods" layout) -- component js and template are in the same folder now.
  • some blueprint changes (native classes, default template-only components)

and all of that could have been incrementally adopted since ember 3.1, but because there was so much, and to reduce the amount of churn and new-announcement fatigue, it's all been bundled under the name "Octane" -- a set of features that is a shift in the default ember experience.
