System 30.3 has been tentatively installed on CADR-1 for the benefit of those
who want to test their programs. There are a number of incompatible changes
described later in this message which will necessitate recompilation for
some people and actual program changes for those who are still using functions
of the old window-system. The 30 series system will be installed on most
machines sometime next week, assuming there aren't too many bugs.
Please do not copy this system to any other machine yet (in fact 30.3 will not
boot on a machine without a color screen, but that will be fixed in 30.4,
hopefully tomorrow.)
Please do not recompile any system programs in worlds older than this,
as that is very likely to cause hidden bugs.
Lisp machine systems 30 and above contain only the "new" window system.
The vestiges of the old window system present in previous systems (with
the "nws" designation) have been removed. In addition, the GLOBAL
package has been cleaned up. It is advisable that you recompile your
programs in this system before trying to run them, both because of
symbols having changed packages and because of some other changes
including the value of the #\MOUSE-n-n syntax. If you need help
in converting please contact HIC, Moon, or MMcM.
There is a new package, TIME. Some of the date/time functions that were
formerly in the CHAOS package randomly, are now in the TIME package.
They work better and present a more reasonable interface.
The following symbols have been removed from GLOBAL; if you use any of
these in your programs you have a problem and need to convert. Some of
these symbols are obsolete, a few were misspellings, and some have been
moved into SYSTEM. A lot of these symbols are used as keywords,
properly requiring a colon prefix, but had been globalized so that old
programs without the colon prefix would work. Said old programs will
now need to be fixed.
These symbols no longer exist in GLOBAL:
