That is correct.

The development of the Unicode Standard is essentially an *engineering*
project, not a scientific one. The editors and the members of the
Unicode Technical Committee try to apply the best quality assurance
practices they can to that process, as new versions are rolled out.
When the decisions were made to release Unicode 4.0, the numerous
updates for Unihan.txt were not yet completed and fully checked, so
the release of the update of that file has been delayed until they
can be completed and checked.

Well, I'll let the maintainers of Unihan.txt speak as to the whimsical
character of the data file ;-), but your inquiry presupposes that
the editors are sitting on their duffs waiting for some indication
that the file should be updated. Nothing could be further from
the truth. Massive lists of additions and corrections have already been
made to Unihan.txt. Those *would* have been released with Unicode 4.0,
had they been ready in time. They *will* be released, when they are

This unfortunately misunderstands the nature of the publication
process. The Unicode Standard, Version 4.0 itself has already
been finalized. It was released on April 17, and is defined
on the website. The data files associated with that release
are all final and frozen, and are available online.
The *book* publication, 'The Unicode Standard, Version 4.0',
published by Addison-Wesley, is a few months behind. It should
be available in early September. When it is available, the
CD-ROM in it will have the same data files as are already
available online -- and they aren't going to be updated
piecemeal in ways that would put them out of synch with the
definitive data files online.
The opportunity for the update of Unihan.txt is the *next*
update release of the standard, likely to be Unicode 4.0.1,
if past practice applies. That will merely be an update of
the online data files, not accompanied by any further
changes in the book.
