The release of Unity 2018 is anticipated in the spring of 2018. There will be some exciting enhancements to the game engine, especially with the stated focus of graphics. 

Here are the highlights of the changes expected for Unity 2018:

• Scriptable Rendering Pipelines (SRP): A new SRP API will be available, giving us finite control of the rendering pipeline via C# scripting. Unity 2018 will include two rendering pipelines (Lightweight and HD) that can be used, replicated, or modified. 
• Upgraded post-processing stack: A new version of the post-processing stack includes automatic volume blending, and enhanced controls for custom effects.
• Shader graph: A visual interface for creating shaders.
• Integrated IDE: MonoDevelop will no longer be shipped with Unity as the integrated development environment for scripting. Windows users will receive Visual Studio 2017, and Mac users will receive Visual Studio for Mac. Visual Studio is a much more robust development environment.
• C# job system: This system will empower developers to create safer multithreaded code with performance gains.
