Today the Ember project is releasing version 3.0.0 of Ember.js, Ember Data, and Ember CLI. Ember 3.0 doesn't introduce any new functionality, instead it focuses the framework by removing long-deprecated APIs and support for legacy platforms.
A major version release with no new functionality: bold move. Perhaps a winning strategy if it can garner similar praise as Apple's Snow Leopard update to macOS (nee OS X).
Ember is like the Energizer Bunny of web frameworks. Can you believe the team has been working on it since 2011? That's like forever in webdev-years.
