Thanks, Thierry.
Actually, there is a recent Grok release that is a well-kept secret:
I got the above info when we got into some windows-based problem on Grok
and I communicated on the list.

Besides, the Grok developers feel, probably rightly so, that Grok is
more-or-less feature complete and that widely-spaced releases are to be
expected. Another explanation is (as quoted): "Another reason why Grok
releases do not happen too often these times is,
that Grok meanwhile is merely an umbrella package for a couple of
outsourced packages (these grokcore.xxx packages). These packages are
frequently updated but normally only as bugfix releases which leaves the
Grok version number as-is."

Thanks, again.
