MS say that win32 is now being called Windows 4.0.  SDKs will ship ``before the end of the year''.

It will extend the existing set of Windows API calls with new 32-bit
kernel, graphics, and network API calls.  Windows-32 will allow each
application to have a large flat address space (up to 2 GigaBytes per
application) which is protected from corruption by other applications.
It will also provide multiple threads and preemptive multitasking.  The
Windows 3 API will be extended rather than replaced, and minimal changes
to existing applications will be required.  Windows 3 applications will
run unmodified under Windows-32, but all such applications will run in
the same address space and will not be protected from one another.  They
will be protected from Windows-32 applications, and vice-versa.  The
Windows-32 graphics extensions will include:  paths, Bezier curves,
transforms, correlations, device-independent colour, and a \mbox{``mass
BitBlt''} for updating portions of screen quickly.  The network
extensions will include support for IPC (Inter-Process Communication)
with peer-to-peer named pipes, and mailslots.  These features are
currently part of LAN Manager.  International support will be improved
by the addition of a single, large character set called Unicode.

As far as the problems which will need to be overcome in moving from
Windows-16 to Windows-32 go, MS claim that no restructuring of source
code would be required, and that minimal source code changes will be
required.  Problems to be overcome fall into three main categories:
differences in sizes of basic types (e.g.\ int, HANDLE), differences in
memory model (segmented vs.\ flat), and differences between 386/486 and
MIPS architectures (structure alignment, etc.).


Thanks to Patrick Hyland who took the trouble to type this stuff in,
from the Developers' Conference.
