Let me clarify what I meant by "latest" -- in all cases, I meant
pre-release, still-under-development software.  My recommendation is
that you continue to use a released version (4.1.4, or upgrade to
4.1.5), use the local documentation in the Help Desk rather than the
online version, and wait for 4.1.6 to be released before using
hash-has-key?.  I don't believe it has been released yet, and is thus
subject to change at any time.
