Allegorithmic released Substance Painter Spring 2019 that is “more officially” – Substance Painter 2019.1 with a lot of new tools and features.
Displacement and Tessellation in both the viewport and Iray
Compare Mask Effect that allows comparing the content of the current layer with the one from the layer stack underneath, similar to the Blend-if function in Photoshop
Procedural brush strokes based on Substance parameters (any Substance file can be used as a material or alpha when painting and becomes aware of each stamp being drawn)
A choice between a Spherical and Planar projection for a layer and a new placement gizmo that makes it easy to move the decal around an asset
Layer Stack and Other UX Improvements
