Long Term Support

Unity 2022 LTS provides a stable foundation for projects that are in production or about to ship. Unity 2022.3 LTS release has the same feature set as the 2022.2 Tech Stream release.

We’re committed to supporting 2022 LTS releases with biweekly updates until mid-2024, after which updates will be monthly until mid-2025 (two years after the initial release date). These updates will only cover fixes aimed at improving the stability of the product to enable users to ship their projects.

Unity 2021.3 is now the legacy LTS. It will be updated monthly until it reaches the end of its support cycle in mid-2024.
