Released: 8. February 2018

Release notes

2018.1.0b6 Release Notes (diff since 2018.1.0b5)

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 2018.1.0b6

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

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

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

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

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

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

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

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

UI: UI Button changes its position after re-entering the playmode (995548)

Animation: Curve with weighted keyframes does not animate properly in the animator (986008)

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.

Progressive lightmapper doesn't work on Linux, which means that all 3D templates will crash on launch. The 2D template should still work.

Features

Editor: Assembly Definition Files (asmdef) assemblies are now compiled on startup before any other scripts (Assembly-CSharp.dll and friends) and compilation does not stop on the first compile error. 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.

Package Manager: Updated Package Manager user interface (from where a project's packages can be managed and new packages can be discovered) to v1.6.1. What's new in 1.6.1:

When updating the package, the user is now asked to confirm temporary closure of the window. Note however that this will only be the case when updating from v1.6.1 onwards. When updating from 1.5.1 to 1.6.1, a restart of Unity is necessary for the update to take effect.

The window is now dockable.

UI style rework, making it consistent with the rest of the Editor.

Added keyboard navigation in the Packages list

Changes

Android: Updated JDK requirements to JDK 8. This a requirement from the latest Android SDK.

Android: We now create a 2048-bit RSA key for signing the apk.

WebGL: Removed experimental label from WebAssembly linker target.

Improvements

XR: Android builds that support ARCore can now be built using target API version 14 or higher.

API Changes

2D: Added DetectChunkCullingBounds to TilemapRenderer to allow for correct culling of large tiles. (971087)

Editor: Explicitly setting the following delegates to null will no longer draw a control handle, instead of drawing using a default implementation: PrimitiveBoundsHandle.midpointHandleDrawFunction, ArcHandle.angleHandleDrawFunction, ArcHandle.radiusHandleDrawFunction, JointAngularLimitHandle.angleHandleDrawFunction.

Editor: Explicitly setting the following delegates to null will now result in a handle size of 0 instead of using a default value: PrimitiveBoundsHandle.midpointHandleSizeFunction, ArcHandle.angleHandleSizeFunction, ArcHandle.radiusHandleSizeFunction, JointAngularLimitHandle.angleHandleSizeFunction.

Fixes
