Additional Information:

* The continuous build delivery version has the latest features and bug fixes, but it may be unstable and break your files.

* If you're looking for a more stable version, consider using a long-term support release like Blender 2.83, which is maintained until June 2025.

* AMD Radeon ProRender is a powerful rendering engine that uses open industry standards to leverage GPU capabilities.

Regarding your issue with downloading the original Blender 2.8, it seems that the download page has been updated and now takes you directly to the latest version. You can try searching for older versions of Blender on other websites or archives if needed.
