I'm reliably informed there's more UNIX-related content planned for z/OS
2.1 than is listed in the preview announcement. The preview announcement is
evidently what IBM feels comfortable describing at this stage, but I
wouldn't be surprised if there's a bit more. (I'm speaking only for myself,
as always.)

Also, you have to read IBM announcement letters in their totality. z/OS
UNIX substantially benefits from new features and improvements that are
listed in other sections besides the section labeled "UNIX." For example,
are the ISPF-related improvements involving much more support for ASCII and
Unicode highly relevant to UNIX? You bet, but they're listed in a different
section as I recall.

zFS, Unicode, and z/OS Management Facility (to pick three examples among
several) all have tons of UNIX relevance -- even exclusive UNIX relevance
-- but they're listed in other sections. For example, z/OSMF is being
enhanced to make it much easier to submit jobs directly to z/OS UNIX. Is
that a UNIX enhancement? Sure, I think so, and also because z/OSMF is
something that lives in UNIX. (And in z/OS 2.1 it'll be much easier to
install and get up and running because it'll be Liberty packaged. The
WebSphere Liberty Profile is very convenient.)

The stream I/O extensions are described pretty well in the preview
announcement, I think. Even if they aren't, all should be clear by
September.
