Expand or release a Live Paint group

Releasing a Live Paint group changes it to one or more ordinary paths with no fill and a .5‑point black stroke. Expanding a Live Paint group changes it to one or more ordinary paths that are visually similar to the Live Paint group, but are now separate filled and stroked paths. You can use the Group Selection tool to select and modify these paths separately.
