Unity 2017.2 introduced the Package Manager, a modular system and API that dynamically loads and updates new Unity-developed features in your projects.

In the upcoming releases, Unity Package Manager will work in parallel with the Asset Store and the legacy .unitypackage format. For the time being, Unity Packages are developed exclusively for Unity-built features. This allows us to build reliable tools and efficient processes that ensure seamless integration in every step of your development cycle.
Many Unity features ship separately from the official Unity build making it challenging to find them all. They might be on the Asset Store, the Unity Forum, or GitHub, for example.
Going forward, all these off-cycle, official features will be discoverable and managed through the Package Manager ecosystem, and delivered in a format that is unified across Asset Store content and Unity-published editor features.
