Updated on December 19, 2017 to include information about Ember.js 2.16-LTS.
Today the Ember project is releasing Ember.js 2.16 LTS (a long-term support
release) and version 2.17.0 of Ember.js, Ember Data, and
Ember CLI.

At EmberConf in March of this year, we announced Glimmer.js, a
library for building modern UI components optimized for the mobile web. I wanted
to give an update on what we've been working on since then.
There were two primary motivations for releasing Glimmer.js as a standalone project:

We are thrilled to share that we have released Ember FastBoot 1.0 (including ember-cli-fastboot addon, fastboot-app-server and other FastBoot libraries).
What is Ember FastBoot?
Ember FastBoot is a server-side rendering solution for ambitious Ember apps,
allowing your Ember apps to use principles of progressive enhancement, such as an initial render of your app without JavaScript.
It provides a complete solution for server-side rendering of your app from development to deployment.

Ember.js (or should we say Amber.js) turned five years old last December. In some ways, five years is a short amount of time. But when measured in web framework years, it feels like a downright eternity.
As Yehuda and I were getting ready for our keynote presentation at this year's EmberConf, we tried to remember what developing web apps was really like in 2011. We knew that the web had changed for the better since then, but I think we both had repressed our memories of how truly awful it was.
