Released: 27. February 2018

Release notes
2018.1.0b9 Release Notes (diff since 2018.1.0b8)
System Requirements Changes

    Removed support for Windows XP in standalone player builds. Windows Vista is the now minimum supported OS for Windows standalone player.
    Deprecated support for MonoDevelop. VisualStudio is now the recommended and supported C# editor on both macOS and Windows.

Known Issues in 2018.1.0b9
    Camera: MAC OSX - Raycasting is incorrect (related to Camera.main.ScreenPointToRay). (978659)
    GI: "SerializedObject target has been destroyed" appears after environment lighting change. (978554)
    GI: Editor crashes after assigning Light Probe Group to Anchor Override Parameter. (1002580)
    GI: In built Player the IsLightmapBakeTypeSupported() GCAllocs 17B every frame when CPU usage is 0.0%. (986319)
    GI: Progressive Lightmapper doesn't work on Linux, which means that all 3D templates will crash on launch. The 2D template is not affected however.
    OSX: [OSX 10.13][2018.1] Rapidly switching between 2 game view tabs multiple times may freeze or crash the editor when rendering with Metal. Note: it's much harder to reproduce on the latest 10.13.4 Beta (17E160e). (991828)
    Particles: Line renderer is rendered in scene/game window when selecting object in the Project window. (972298)
    Scripting: [.NET 4.6] Editor crash on "scripting_stack_trace_info_for" when opening a project containing BehaviorDesignerEditor.dll. (1005030)

Features
    Scripting Upgrade: Scripting Runtime Upgrade is no longer Experimental.

Changes
    IL2CPP: Deprecated BuildOptions.IL2CPP, which actually never did anything. (986326)
    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:
        Projects configured with a NuGet should change their configuration to point to another folder (default repository path for NuGet configuration is \packages). The risk of NuGet and Unity Package Manager sharing the Packages folder is minimal, but we suggest to separate them nonetheless to avoid any issues.
        When opening a project created with a previous version, a migration flow will copy the content of the UnityPackageManager folder to the Packages folder. It is left to the project maintainer to erase the UnityPackageManager folder and update source control configuration.
    Windows: The Build Player location selection dialog now asks for a folder rather than a file name when building Windows standalone player. The BuildPipeline.BuildPlayer API is not affected by this change. (995320)

API Changes
    AI: New experimental API for NavMesh queries, usable within C# jobs: namespace UnityEngine.Experimental.AI; struct PolygonID; struct NavMeshLocation; enum PathQueryStatus; enum NavMeshPolyTypes; struct NavMeshWorld; struct NavMeshQuery with these methods: BeginFindPath(), UpdateFindPath(), EndFindPath(), GetPathResult(), IsValid(), GetAgentTypeIdForPolygon(), MapLocation(), GetPortalPoints(), MoveLocations(), MoveLocation(), PolygonLocalToWorldMatrix(), PolygonWorldToLocalMatrix(), GetPolygonType(), Dispose().

Fixes
    Animation: Fixed NullReferenceException when calling AnimationUtility.SetAnimationEvents. (989647)
    Asset Import: Fixed handling of Object fields on ScriptedImporters so that they can be assigned a value in the inspector.
    Asset Import: Fixed AssetImporter.GetAtPath when the asset is imported by a ScriptedImporter.
    Editor: Added a list of whitelist paths, which will be the only ones to get copied/replaced when cloning a template in project. (996769)
    Editor: Fixed null reference exception from InspectorWindow.OnSelectionChange() callback during certain operations. (851988, 970700)
    Graphics: Added support for Cube RenderTexture as a cookie on PointLight. (999718)
    Scripting: Fixed IndexOutOfRange exception on x64 when indexing into array with negative values. (967679)
