Following a beta release in September, Unity have just released the full version of Unity 2018.3.  The marquee feature of Unity 2018.3 is the new ability to nest prefabs inside other prefabs which will give game developers massive flexibility in how they structure and organize their games and is a feature developers have been asking for since Unity was first released!  Unity 2018.3 also contains major new features to the terrain system which we showcased in this earlier video.  A new GPU powered particle system called Visual Effect Graph is also available in preview format, along with a new isometric tilemap support, HDRP & LWRP improvements, a new Visual Studio Code debugger plugin, improved package manager and settings windows plus much more.


Details of the release from the Unity blog:

Over the years, one of the features we’ve heard you requesting most often has been the ability to nest Prefabs. After conducting numerous interviews, usability tests and research at game jams, however, we found out that a lot of you also needed several other changes to the Prefab workflows. Therefore, we have been improving the whole system with a focus on reusability, control and user-friendliness.

The new Prefab workflows allow you to split up scenes and Prefabs on a granular level. They give you greater flexibility, increase your productivity and enable you to work confidently without worrying about making time-consuming errors.

Continuing our focus on workflow improvements, Unity 2018.3 now has unified Settings windows for Project Settings and Preferences. The new windows are dockable and searchable, which makes it much more convenient to quickly find and change settings.

The default scripting runtime is now .NET 4.x. The old .NET 3.5 runtime has been deprecated and support for it will soon be dropped. Projects that target the .NET 4.x scripting runtime will be able to use the open-source Roslyn compiler.

In this release, we also added a PhysX 3.4 upgrade that comes with improvements to stability and performance as well as support for multiple worlds and C# Job queries.

The world-building 2D Tilemap tool now enables you to build isometric Tilemaps, which makes it easier to create 2D projects such as strategy, tycoons and simulation games.

Unity 2018.3 also ships with an update to the Terrain system, which marks the beginning of a larger overhaul. In this update, our focus has been not only to set the foundation for further improvements with a few tweaks to the UI and tools but also to improve performance. We also added High-Definition Render Pipeline (HDRP) and Lightweight Render Pipeline (LWRP) support.

Unity 2018.3 includes a number of improvements to the HDRP (preview). This version adds preliminary support for VR and multisample anti-aliasing and improves support for PC, Mac, XBox One and PS4. The UI of various Inspectors of HDRP elements is now updated: Camera, Lights, Reflections Probe, and Material. Finally, we added a new lighting model, so you can author more complex materials.

We are also introducing the GPU Progressive Lightmapper in Preview for Windows and several improvements to lighting.

Our new Visual Effect Graph, which ships in Preview as a package, enables you to create beautiful effects using a node-based system that is both easy to use and flexible. Inspired by leading VFX software tools for films, it empowers artists to create stand-out visual effects for games and other projects with millions of particles running on the GPU.

Unity 2018.3 also includes several new features for the existing Particle System. For example, there are Particle Meshes that can now be flipped just like with billboards, Particle Lights that now support Real-time Global Illumination, and the new Ringbuffer Mode, which makes it easier to create persistent effects like footprints or bullet holes by keeping particles visible after their lifetime expires and until they are replaced.

Mobile improvements include Dynamic Resolution Scaling support for Vulkan and Metal, Android AppBundle generation support and faster APK package build times on Android with APKzlib.

For XR, we added Native Support for Daydream Controllers, Haptics APIs for VR controllers, and updates to the AR Foundation as well as XR Performance Testing.
