What is Ember Octane?
Octane, Ember's first Edition, was released in December 2019
Ember Octane introduced a programming model in Ember that brought major gains in productivity and performance, incrementally via a series of minor (non-breaking) releases. This allows for new apps to have the best features enabled automatically, while teams working on existing apps can migrate over time and continue updating their app's dependency versions.
