Долгосрочная поддержка

Unity 2021 LTS provides a stable foundation for projects that are in production or about to ship. Unity 2021.3 LTS stream release has the same feature set as the 2021.2 Tech stream release.

We’re committed to supporting 2021 LTS releases with biweekly updates until mid-2023, after which updates will be monthly until April 2024 (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 2020.3 is now the legacy LTS; it will be updated monthly until it reaches the end of its support cycle in mid-2023.
