Ember 2.4-LTS, the first Ember Long-Term Support release, lands today as Ember
2.4.5. Future versions of 2.4 will be considered part of the LTS channel.
The LTS channel comes with a commitment
that low-risk critical bugfixes and security patches will be backported to
these versions. Additionally, any change to commonly used private APIs must be deprecated
in at least one LTS release before removal, making LTS releases a slower
moving target for addons to support.
