Unity 2018.1.0b5 release notes
2018.1.0b5 Release Notes (diff since 2018.1.0b4)
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 2018.1.0b5

    Animation: Configure button doesn't get enabled when the model rig is set to humanoid (980511, 984843)

    Animation: Null Reference exception occurs when trying to add/delete the event or changing sample number. (989758)

    Audio: [Audio Mixer] Crash on play when duplicated audio group is assigned to audio source (962084)

    Editor: "Assertion failed" exception is generated on opening a project on Mac OSX (977901)

    Editor: Cannot Quit Application from launcher using Unity>Quit nor cmd+Q (993381)

    Editor: Unity crashes when the user quits the Editor via menu item Unity | Quit. (991358)

    GI: AddInstancePropertiesJob error while baking with specific assets (973689)

    GI: Baking pipeline still runs even if GI systems are disabled (989061)

    GI: Editor freezes on 'Writing Lighting Data' when baking multiple scenes in Build Settings (989055)

    GI: [UI] New parameters are incorrectly introduced for directional, spot and point lights (988956)

    Graphics: ReflectionProbes that are outside of camera frustum are not culled in SRP (visibleReflectionProbes) (991212)

    Graphics: [UI] Multiple debug scene visualization modes are broken (988955)

    OSX: [OSX 10.13] Switching between 2 game view tabs multiple times freezes editor (991828)

    Particles: Line renderer is rendered in scene/game window when selecting object in the Project window (972298)

    Particles: Unity crashes when duplicating/moving nested particle systems with a disabled renderer (988423)

    Templates: Project templates will be updated in subsequent betas to address the following points:
        The 2D template currently creates a default scene with a UI canvas: this will be removed in a subsequent build.
        The 3D Ultra template is missing the "Preview" tag currently.
        All templates: Lighting settings improvements to come in a subsequent build.

Features
    Package Manager: Updated Package Manager user interface (from where a project's packages can be managed and new packages can be discovered) to v1.5.1. What's new in 1.5.1:
        Moved menu item to access the Package Manager UI window from "Project -> Packages -> Manage" to "Window -> Package Manager".
        The "Install" tab now shows the latest version (and description) available for each package, rather than the current version.
        The "Update to" button is no longer displayed when the current version is the same as (or greater than) the latest one available.
        The UI now displays "alpha", "beta", "experimental" and "recommended" tags for packages, as appropriate. Previous versions did not display such tags, so it was not possible to determine the status of packages.
        UI polish.
    Launcher: The launcher now allows users to select one of the new project templates when creating new projects. Project templates available currently: 2D, 3D, 3D Ultra (Preview), Lightweight (Preview), Lightweight VR (Preview), and High Definition (Preview).

Changes
    Android: Newly created projects now default to ARMv7 CPU architecture.
    XR: Standalone UWP applications targeting Windows Mixed Reality will now cause the OS to notify the user if the Mixed Reality components are not installed or a headset is not connected, rather than silently falling back to non-VR desktop mode.

Improvements
    Asset Import: In optimized mode, if a root bone is specified in the unoptimized SkinnedMeshRenderer and its transform has also been exposed, the root bone will now be kept as is, otherwise it will be set to root. (972082, 988438)
    iOS: Added a checkbox to the iOS plugin importer: when checked, the plugin is added to the "Embedded Binaries" folder. (984264)

API Changes
    UI: Added characterLimit property for TouchScreenKeyboard.
