With the recent release of its pzprxs implementation, here's another Isowatari. We've never actually had a normal-shaped N = 4 Iso before today... now balance has been restored to the universe. No, N = 0 and N = 1 have not been forgotten.

Rules: Shade some cells so that all unshaded cells form one orthogonally connected area and no 2x2 region is entirely unshaded. Black circles must be shaded and white circles must be unshaded. All orthogonally connected groups of shaded cells must be the size indicated above the grid.

Here's a few previous appearances:
