Unity 2019 LTS is now available, the game engine announced.
The long-term support version of Unity 2019 contains everything from the previous three TECH stream releases, with all the fixes and improvements they’ve added to Unity 2019.3 since it was released earlier this year. You can find the complete details in Unity's blog post, and in the video below.
Here's part of the announcement:
Unity 2019.1, 2019.2, and 2019.3 have brought lots of improvements in rendering, Editor UI, node-based authoring tools, and more. Today, we’re releasing Unity 2019 LTS, which includes all of these features, as well as additional fixes for maximum stability.
As part of our commitment to improving the development process for users, Unity is now shifting to offering LTS as the default version of the platform, and we have committed to doing fewer releases per year. You have been incredible in helping us understand your needs, and we’re grateful for your feedback. In response to this we have improved, and will continue to improve, workflows and modernize Unity to be more flexible, focusing on delivering stability and interoperability of features.
Beginning today with the release of 2019 LTS, the LTS versions of Unity will become the default available for download from the Unity Hub. Moving forward, Unity will issue up to two TECH stream releases per year followed by the annual LTS release. The TECH Stream is for creators who demand to be on the cutting edge as technologies and workflows are evolving, while LTS is suggested for creators aiming to ship their projects in the near future, or for those who have everything they need in 2019 LTS. This shift in release philosophy will ensure that you are installing the most stable version for projects in production.
What’s in the 2019 LTS?
The new Long-Term Support (LTS) version of Unity contains everything from the previous three TECH stream releases with all the fixes and improvements we added to Unity 2019.3.0 since it was released. Similar to our previous LTS releases the focus for 2019 LTS isn’t new features, API changes or enhancements, but defect rectification and usability upgrades aimed at improving the stability of the product. In short, it’s a continuation of the 2019 TECH stream without new features which is why we also call it Unity 2019.4.0.
How the different versions impact you
If your project is shipping soon you’ll want to lock in on 2019 LTS to ensure maximum stability. If you are in the pre-production phase the Unity 2020.1 TECH stream release is recommended as a great fit for those who want to explore bleeding-edge technologies and will be coming out of beta in a few weeks.
- For users currently building on 2017 LTS we also highly recommend upgrading to the new 2019 LTS, keeping in mind that the two-year support stream for this version ended in April 2020. You’ll find more info and links to the upgrade guides in our blog post from April.
- If you are coming from Unity 2018.4 LTS you’ve already heard about tools like the Scriptable Render Pipeline (SRP), the Visual Effect Graph, the Shader Graph, Nested Prefabs, Addressables and new 2D tools. All of these tools are now verified for the 2019 LTS release and are recommended for use in productions.
- For those adopting 2019 LTS you will benefit from all the features released in Unity 2019.1, 2019.2 and 2019.3.
