This is the LTS distribution version: just the base framework, intended to be installed as a package using the Unity Package Manager and used by different tools simultaneously, without any framework modifications by individual tools.

For the development version, take the latest release from develop, intended to be used in tools aiming to modify the framework core and embed the framework in their distribution. This requires them to modify the namespace and make sure it does not conflict with other tools.
