Describe the bug
The docs still include some of the removed util functions, and the ones that have moved are not accurately reflected in the docs.

For the removed functions it would be good to have some kind of path forward for those utilities or to have them restored if they were erroneously removed.

Expected behavior
config.util.getEnv has an alternative utility or is put back

Other information

It appears that in the v4.1.0 release, several config.util functions were deprecated and slated for removal. I didn't see anything mentioned in the release tag for this or in any of the previous v4.x.x updates save for a mention about moving utilities in the patch update for v4.0.1.

I may have missed it burred somewhere that these were slated for deprecation.

But I must also voice my frustration with how a breaking change was published as a minor version update
