No, GS doesn't redirect changed slugs. Just like WordPress and most CMSes.
However it wouldn't be difficult to make a plugin that saves slug changes and does the redirects...
In the meantime you could use one of the redirect plugins available, but you have to specify the redirections manually.
Parent change is another thing. A workaround is enabling canonical redirects via gsconfig, but this has problems with several plugins that use parameters in URLs (news/blog/items managers, etc.)
