Ember follows Semantic Versioning. The Ember team aims to ship new features in minor releases, and make major releases as rare as possible. A minor release is published about once every six weeks.

Long Term Support

Once a release of Ember gets promoted to LTS, it receives bugfixes for 36 weeks and security updates for 54 weeks.

An LTS is declared roughly every 4 minor versions, excluding the x.0 minor version. The last minor version before the next major release is also considered to be an LTS. For example, in Ember 2.x, the following versions were considered LTS’s: 2.4, 2.8, 2.12, 2.16, and 2.18 (last version).

Before a version can be called an “LTS” release, it has to spend at least 6 weeks as a stable release, where it is used and tested by thousands of developers.

More information is available on the Ember website.

You should be running one of the supported release numbers listed above in the rightmost column.
