"overrideMonoSearchPath" specifies an extra folder to search when Mono is loading assemblies. One intended use is two versions of the same project i.e. trial and full version. The assets are the same but the scripts are different. This command line option can be used to re-use the assets but load different scripts.

Player: (Also mentioned under API changes) Added an experimental API which allows to change the order in which engine systems are invoked, remove engine systems from the update order, or insert new C# entrypoints at any point in the update cycle: UnityEngine.Experimental.LowLevel.PlayerLoop .

GI: [Experimental] Added new experimental C# interface to pass light information to the GI baking backends.

GI: Progressive Lightmapper is now out of preview!

GI: Added experimental API for baking sky occlusion in Progressive Lightmapper. The sky occlusion value for a given input position denotes what fraction of the sky is visible for that point. It takes into account any lightmap static object. The sky occlusion allows you to apply the correct amount of sky lighting to objects that are otherwise hard to lightmap, such as trees and foliage.

All asmdef assemblies that succesfully compile and have all their references compiled are loaded before compiling the remaining scripts (Assembly-CSharp.dll and friends). This ensures that Unity packages are always built and and loaded regardless of other compile errors in the project.

Editor: Added Templates for 3D, 2D, Lightweight (Preview), Lightweight VR (Preview), and High Definition (Preview) to streamline the new user experience with Scriptable Render Pipeline features as well as to define better starting points for graphical, player, and lighting settings. Note that these are not yet easily selectable - this will come soon via an update to the Launcher.

Windows: Removed support for Windows XP in Standalone Player builds. Windows Vista is the minimum supported OS now.

Web: AssetBundle related parts of UnityWebRequest have been split into a new module, allowing UnityWebRequest to be used without pulling in AssetBundle module. API change: UnityWebRequest.GetAssetBundle -> UnityWebRequestAssetBundle.GetAssetBundle .

Universal Windows Platform: Build & Run now defaults to 64-bit player when run on local machine.

Substance: Built-in support for Substance Designer materials is deprecated in Unity 2017.3, and will be removed in 2018.1. To continue using Substance Designer materials in Unity 2018.1, you will need to install a suitable third-party external importer from the Asset Store.

Package Manager: Unity Package Manager project sub-folder was moved from UnityPackageManager to Packages. This is to align the physical path with the logical path of packages. Notes:

Editor: Plug-in code that creates textures used in rendering with IMGUI should now avoid specifying them in linear space (i.e. should set the linear parameter to false in the Texture2D constructor). Otherwise, GUI elements drawn with such textures may look washed out when the project is working in Linear space (Player Settings > Color space: Linear). (908904)

Editor: Compiling 'unsafe' C# code now requires the "Allow 'unsafe' code" option to be enabled in the player settings for predefined assemblies (Assembly-CSharp.dll, etc.) and in the inspector for Assembly Definition Files assemblies. Enabling this option will make Unity pass the /unsafe option to the C# compiler when compiling scripts.

Editor: Added InspectorWindow.OnPostHeaderGUI callback to allow drawing of custom GUI elements in the inspector window.

Graphics: In forward rendering do not fetch 2x2 white shadowmask texture when liting a realtime object with a mixed light using baked occlusion. (952761)

Graphics: Improved shader import handling when using #pragma target . If no #pragma geometry , #pragma hull or #pragma domain statements are used to specify entrypoint functions, these shader features (geometry or tessellation) are now dropped from the internal shader capabilities requirement, allowing greater compatibility across non-DX11 graphics targets. In practise, this now allows using #pragma target 5.0 with Metal, as long as geometry shaders are not used.
