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.
