Support sur le long terme

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.

Changes

  • Package Manager: Changed the package installation process to no longer set package directories and files as read-only on disk. This prevents all sorts of possible corruption scenarios (e.g. read-only directories, partially-read-only packages in the package cache) and avoids some permission issues when removing packages.

  • Package Manager: Changed the package installation process to systematically revert packages to their original state. Note: this has the side-effect of actively reverting local modifications in immutable packages, which could previously be kept until the dependency was updated to a different version of the package. In order to preserve local changes, a package should first be [embedded in the project](https://docs.unity3d.com/Manual/upm-embed.html).

Improvements

  • Package Manager: Added support for configuring additional SSL certificate authorities, including self-signed certificates. See the [Unity Manual](https://docs.unity3d.com/Manual/upm-network.html#SSL) for more information on how to use this.

  • Package Manager: Added support for Git URLs with the SCP format (e.g. git@github.com/user/repo).

  • Package Manager: Added support for Git URLs without a trailing .git by using git:// URLs or prepending git+ to URLs (e.g. git+https://github.com/user/repo).

  • Package Manager: Added support for tarball-based dependencies (e.g. "file:.tgz").

  • Package Manager: Changed the UnityEditor.PackageManager.Client.Add method to make the @ prefix optional when adding Git-based dependencies and local dependencies (file:).

  • Package Manager: Reduced the amount of data transferred over the network when fetching package metadata from the registry.

Features

  • Multiplayer: Added UNET encryption support.
