Corinna could you fill in the part near the end?

Corinna, Pierre, could you add some lines detailing your security
changes and, if needed, flesh out my descriptions of your changes?

Thomas, I don't know if you are still reading this list but if you
could add some details on your thread changes, I'd appreciate it.

I've made a new version of the Cygwin DLL and associated utilities
available for download.  As usual, a list of what has changed is below.

I'd like to send a special thanks to Thomas Pfaff who is stepping down
as the cygwin pthreads maintainer.  His efforts in improving pthreads
functionality were greatly appreciated.  He will be missed.

To update your installation, click on the "Install Cygwin now" link on
the http://cygwin.com/ web page.  This downloads setup.exe to your
system.  Then, run setup and answer all of the questions.

If you have questions or comments, please send them to the Cygwin
mailing list at: cygwin@cygwin.com .
