Long Term Support

The LTS stream is for users who wish to continue to develop and ship their games/content and stay on a stable version for an extended period.

The LTS version will not have any new features, API changes or improvements. It will address crashes, regressions, and issues that affect the wider community, such as Enterprise Support customer issues, console SDK/XDK, or any major changes that would prevent a large section of users from shipping their game. Each LTS stream will be supported for a period of two years.
