Ember 3.16 released

Today, the Ember project released version 3.16 of Ember.js, Ember Data, and Ember CLI. This version of Ember.js is the LTS (Long Term Support) release candidate. LTS candidates prioritize stability rather than adding new features, and have an extended support timeline.

This version started the 3.17 test cycle for all sub-projects. We encourage our community (especially plugin authors) to help test these beta versions and report any bugs before they are released as the final version in six weeks.This Embers try Plugins are a great way to continuously test your project against the latest Ember version.
