Long Term Support
Unity 2020 LTS provides a stable foundation for projects that are in production or about to ship. Unity 2020 LTS stream release has the same feature set as the 2020.2 Tech stream release.
We’re committed to supporting 2020.3 LTS releases with biweekly updates until mid-2022, after which updates will be monthly until March 2023 (two years after the initial release date). These updates will only cover usability fixes aimed at improving the stability of the product to enable users to ship their projects.
Unity 2019.4 is now the legacy LTS; it will be updated monthly until it reaches the end of its support cycle in spring 2022.

Editor: Fixing double consecutive OnDisable calls for inspectors while entering playmode or during assembly reload (1159201)
Editor: Preset target has the Preset asset name in the Preset inspector instead of a blank name so custom inspector can always rely on the .target.name value to be the asset one. (1210891)
Editor: prevents hang from calling capturescreenshotastexture() outside of playmode (1238552)
