Logic Puzzles #55-57 - Rever's 25 days of underloved puzzles - Day 6

 Heyablock

Day 6! Today, we have a genre that is similar to heyawake, except that the shaded cells can be adjacent! Heyablock is truly an underrated gem and I'd love to see more of it!

Rules and link

Shade a single group of orthogonally connected cells in each region so that the remaining unshaded cells form one orthogonally connected area. Shaded groups may not share a bold border. Regions with numbers must contain the indicated amount of shaded cells. Unclued regions must contain at least one shaded cell. A line of consecutive unshaded cells may not cross more than one bold border.
