Paint 3D's impending demise was revealed through a banner that appears for some people in the app itself. But if you're a fan, there is some good news.

Paint 3D launched in 2017 with the Windows 10 Creators Update. It combined Microsoft Paint and 3D Builder applications to create a hybrid 2D-3D editing experience.

Krita is a free and open source application designed for digital painting, 2D animation, and image editing. Originally designed for Linux, Krita has also been available for Windows since 2014.
