unity lts
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.
Unity 2019.1、2019.2和2019.3在渲染，编辑器UI，基于节点的创作工具等方面进行了许多改进。 今天，我们将发布Unity 2019 LTS ，其中包括所有这些功能以及最大稳定性的其他修复程序。
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.
作为我们致力于改善用户开发过程的承诺的一部分，Unity现在正在转变为提供LTS作为平台的默认版本，并且我们承诺每年减少发行量。 您在帮助我们了解您的需求方面发挥了不可思议的作用，我们感谢您的反馈。 响应于此，我们改进了并将继续改进工作流程，并使Unity更加现代化，从而更加 灵活，专注于提供功能的稳定性和互操作性。
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.
从2019年LTS的发布开始 ，Unity的LTS版本将成为可从Unity Hub下载的默认版本。 展望未来，Unity每年将发行最多两个TECH流，随后是年度LTS。 TECH Stream适用于需要随着技术和工作流程的发展而处于最前沿的创作者，而LTS则建议旨在在不久的将来发布其项目的创作者，或那些在2019 LTS中拥有所需功能的创作者。 发布理念的这种转变将确保您为生产中的项目安装最稳定的版本。
2019 LTS中有什么？ (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.
新的Unity长期支持(LTS)版本包含前三个TECH流版本的所有内容，以及 自 发布 以来 我们添加到 Unity 2019.3.0中的 所有修复和改进 。 与我们之前的LTS版本类似，2019年LTS的重点不是新功能，API更改或增强，而是旨在改善产品稳定性的缺陷纠正和可用性升级。 简而言之，这是2019 TECH流的延续，没有新功能，这就是为什么我们也将其称为Unity 2019.4.0。
不同版本如何影响您 (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.
如果您的项目即将交付，则需要锁定2019 LTS以确保最大的稳定性。 如果您正处于预生产阶段，则建议将Unity 2020.1 TECH流发行版非常适合那些想要探索尖端技术的人，并将 在几周内发布 Beta版 。
- 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.

Unity 2020发布计划 (Unity 2020 release plans)
We are reducing the number of TECH stream releases from three to two per year in order to enable more stable use of the platform. More and more features are being distributed as packages and are being continuously updated and the longer release cycle provides the extended stabilization phase needed to validate and improve the stability and quality of our tools in between releases. As a result you will have fewer major releases to upgrade between updates.
我们将每年TECH流发布的数量从三个减少到两个，以便能够更稳定地使用该平台。 越来越多的功能作为软件包进行分发，并且会不断更新，更长的发布周期提供了扩展的稳定阶段，以验证和改进两次发布之间工具的稳定性和质量。 结果，您将有较少的主要版本在更新之间进行升级。
In a few weeks we’re also shipping the first TECH stream release of this year – Unity 2020.1, which will bring even more usability improvements and stabilized workflows to features introduced in previous releases. These improvements are part of our renewed focus and investment in better workflows, stability, quality and interoperability for all of Unity’s features in upcoming releases. If you’re eager to learn and try out what the latest features offer, check out our beta blog post.
再过几周，我们还将交付今年的第一个TECH流版本-Unity 2020.1，它将为以前版本中引入的功能带来更多的可用性改进和稳定的工作流程。 这些改进是我们重新关注和投资的一部分，这些投资用于改进即将发布的版本中所有Unity功能的工作流程，稳定性，质量和互操作性。 如果您想学习并尝试最新功能，请查看我们的 beta博客文章 。
