Long Term Support (LTS) + Tech Stream

Understand the features and benefits of Unity’s release versions.

Choose the right release for you

We offer two different release versions so you can download the solution that best fits your needs. Tech Stream versions give you access to the latest in-progress features, while the LTS version ensures greater stability with two years of support.

Long Term Support (LTS)

The release for creators who value maximum stability and support for their next project. The LTS version rolls up the quality features and improvements made across the year into a single installation. This is our default release, and is recommended for creators who are about to lock in production on a specific version of Unity.

2022 LTS

Released once a year

The last Tech Stream release becomes an LTS release after extensive additional stabilization for maximum quality.

Supported for two years

An LTS release receives continued support for two years following publication, in the form of biweekly updates with bug fixes.

No new features or API changes

Updates address crashes, regression bugs, and any major issues, without introducing additional tools or technology.

Tech Stream

Tech Stream is for creators who value getting earlier access to new features in order to prepare for future projects. These versions are primarily recommended for the preproduction, discovery, and prototyping phases of development, but they can be used to get ready for the next LTS by enabling earlier feature adoption.

Released twice a year

Since the 2020 release cycle, we publish two Tech Stream releases each year. These are typically issued in Q1 and Q4.

Supported until next release

Updates and bug fixes are added to the current Tech Stream release on a weekly basis until the next Tech Stream is officially published.

Features are in-progress

Tech Stream features are actively being developed and shaped by feedback from early adopters. The second Tech Stream in a cycle is the foundation for the next LTS release.

What’s the difference between a Verified package and a Released package?

In an effort to provide more clarity around package readiness and expected release date, better quality packages, and as a direct response to feedback from you, we’ve created a more rigorous process for labeling packages, as well as a new categorization system.

How do I get access to your alpha and beta releases?

Both our alpha and beta releases are open to everyone, so no signup is required. Get started by downloading them from the Unity Hub. Because there may be feature-stability issues with these early releases, we do not recommend them for projects in production, and we highly recommend that you back up any project before you open it with an alpha or beta release.
