Unity has two releases: Tech stream and LTS.

Tech stream releases are released twice a year (each one receiving weekly updates), and are supported only until the next tech stream release is out.

Unity LTS releases are released once a year and are based off the previous tech stream branch. LTS releases offer two years of bi-weekly updates, then an additional year of monthly updates.

Officially supported platforms as of Unity 2020 LTS are:

  • Mobile: iOS, Android (Android TV), tvOS
  • Desktop: Windows (Universal Windows Platform), Mac, Linux
  • Web: WebGL
  • Consoles: PlayStation (PS4, PS5), Xbox (Xbox One, Xbox Series X/S), Nintendo Switch, Stadia
  • Virtual/Extended reality: Oculus, PlayStation VR, Google’s ARCore, Apple’s ARKit, Windows Mixed Reality (HoloLens), Magic Leap, and via Unity XR SDK Steam VR, Google Cardboard.
