Panorama180 Render was validated for each Unity version and pipeline type (Built-in/LWRP/HDRP/URP).
For Built-ins, you can use the Post Processing v2 package.
For URP/HDRP, both URP/HDRP will be Post Processing with Volume in Unity 2019.
HDRP does not enable the On/Off option for Post Processing in Panorama180 Render.The Post Processing settings for the specified camera will also be reflected in the panorama expansion.

For VR execution, Unity 2019.4-2020 was used and validated with Oculus Integration v.29.
Unity 2021 was used and validated with Oculus Integration v.35.
This will be supported in Unity 2019.4.4 and later, so I have not tested VR in earlier versions.
I have not done any VR verification with HDRP.

For use with PC-VR, Built-in or URP after 2019.4.4.
For native execution of Oculus Quest2, Built-in 2019.4.4 or later is likely to be stable.
In the case of URP, the results seemed to be different depending on the version of Unity 2019/2020.
Please also refer to "Notes by environment" for other environment-specific operations.

This is an older version of the information.
Basically, the scripts and shaders are written in such a way that they will work with past versions, but we do not guarantee that they will work with Panorama180 Render.
Panorama180 Render was validated for each Unity version and pipeline type (Built-in/LWRP/HDRP/URP).
