Unity 2020 LTS

The LTS release is for creators who value maximum stability and support. It includes improvements to streamline your coding experience, improved testing and profiling, and other enhancements. Achieve more in less time, all with a smoother workflow – then deliver your game to the widest possible audience.

First seen in 2020.2, Safe Mode is now in the 2020 LTS


Unity now comes with Safe Mode, so you can load up the Editor with a simpler interface to address any compilation issues in your project. This lets you focus on providing a great experience for your users by harnessing streamlined productivity and a superior development workflow.


Unity 2020 LTS improves coding efficiency by supporting most of the latest C# 8 syntax additions, such as streamlined switch expressions and nullable reference types. Unity supports many other additions to C# 8 to give you the ability to write less code for more functionality.


Developers, get the most out of your project with our profiling tools. In the Unity Profiler, you can now see performance data in charts, gain insights into serialized functionality to identify potential areas ideal for multi-threaded code, and access a Profiler API that exposes performance data points at runtime.

Build once, deliver anywhere

Take your content anywhere your users want you to be. With Unity, you’ll get the most out of today’s hardware, including AR, VR, mobile, and PC devices – and be ready for whatever comes next.

OpenXR support

Unity now supports OpenXR, an open standard provided by Khronos, to help you maximize your reach across a wide range of AR and VR devices.

AR Foundation 4.0

AR Foundation 4.0 supports ARKit scene mesh reconstruction using LiDAR sensors on the iPhone 12 Pro and iPad Pro to enable AR experiences that bring a new level of realism.

Quest 2 support

Leverage Unity’s latest features and technology to bring stunning experiences to life on the Oculus platform. You can also use Oculus Link to iterate on projects directly from the Unity Editor.

Adaptive Performance 2.0

Adaptive Performance 2.0 comes with sample projects to showcase new features including Variable Refresh Rate, Scalers, and the Adaptive Performance Simulator extension, which emulates Adaptive Performance on any device.

2021.2 Tech Stream

The Tech Stream release is for creators who value having early access to newer features that help them stay on the cutting edge. With continued focus on increasing stability and improving iteration speed, this release includes an upgrade to the latest Mono, feature sets, performance improvements for a large number of in-Editor operations, and much more.


Ensuring you have access to the latest syntax and coding standards is a top priority for Unity. We’ve upgraded the bundled Mono version and exposed the latest .NET language features via C# 8, leapfrogging years of Mono versions. Also, .NET Standard 2.1 is now supported.


Feature sets are a new way of efficiently adding related packages to your project with one click, giving you confidence that you’re not missing any essential features to achieve a specific outcome, such as 2D or VR development. We’ve also made huge strides in improving iteration speed, especially import and build times.

We’re improving our render pipelines across the board. For example, improved stability for our VFX Graph implementation and advanced Shader Graph integration in VFX Graph means your graphics code runs more smoothly and with more features such as rendering lit particles in the Universal Render Pipeline (URP).

Platform reach for your projects

We’ve continued to build capabilities for you to target different platforms with great performance and innovative features.

Get started with AR and VR templates

Boost your productivity when creating AR and VR projects with templates that ensure the correct packages are installed. They’ll also set you up with a default scene hierarchy, along with clear next steps to finish configuring the project to meet your needs.

Android asset building

To ensure seamless Play Store publication, we’ve added direct support within Unity for Google Asset Delivery requirements. This handles bundling assets together to fit within the size limits the Play Store expects for installation, then easy access for “fast follow” asset delivery.

Improved Oculus latency

We’ve reduced rendering latency on VR hardware such as Oculus Quest with support for late latching and motion vectors.

OpenXR support

We’ve built on our OpenXR support to allow you to target any OpenXR-conformant device, including Windows Mixed Reality, HoloLens 2, SteamVR, and Oculus Rift and Quest.

Increase graphic performance with NVIDIA DLSS

NVIDIA Deep Learning Super Sampling (DLSS) for the High Definition Render Pipeline (HDRP) uses AI to run real-time ray-traced worlds at high frame rates and resolutions, with a substantial performance and quality boost for rasterized graphics.

Adaptive Performance 3.0

Unity’s continuing partnership with Samsung helps to provide you with the tools you need to get best performance for your mobile-based projects.
