The .../latest/... URLs have always been unstable, by definition.
Functions might move between modules, modules might appear and
disappear, entire libraries might be added or removed, the format of
internal anchor names might change, etc. I don't think it makes sense
for hoogle to point to them.

We could add redirects base/* -> base-* etc now, but we'd have
to keep it up-to-date after each release. We could probably make a small
shell script to do so, so maybe that would be the best plan.

On the other hand, we might be better off just removing the latest/
link. People looking for library docs would be better served by a
Haskell Platform doc page anyway. We'd need to work out what to do with
the links in the GHC docs, though.

You could also use e.g. the
docs, which are stable.
