New system pre-release

[Moon at MIT-AI (David A. Moon)]

System 32.1 and microcode 674 are tentatively released.  Currently
they only exist on CADR-1, but very shortly they will migrate to
CADR's 6 and 2; if no bugs show up I hope that this system can get
installed on all the machines within a week or so.  That will involve
some disruption to users, although you can of course DISK-RESTORE to
an older band if your programs have not yet been converted to the
latest system (but don't expect great amounts of sympathy for bug
reports!)

In addition to the changes in system 30, mainly involving removing the
vestiges of the old window-system, this system includes a relatively
bug-free new window-system and editor.  The garbage collector works
again.  This system includes the micro-compiler (ask RG if you want to
know how to use it.)  There are some new facilities for transferring
bands between machines which are faster and hopefully more reliable.
The microcode primitives for the old window-system have been removed
(TV-DRAW-CHAR, TV-ERASE, etc.); if you call them unfortunately the
machine will crash rather than giving you an error.  There are the usual
large number of small bug fixes.

Any qfasl file compiled in a system before 30 should be recompiled
in this system, because many symbols have been removed from the GLOBAL
package.  The list is at the end of this message; note that this is
the same list as for system 30 except that UNTYI has also been moved\n from GLOBAL to USER.  (It was on the list before but it was not actually
moved due to an oversight.)

Please do not recompile any system programs in worlds older than this,
as that is very likely to cause hidden bugs.

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.  Note that
this includes NWATCH-ON and WHAT-DATE which many people call in their
init files.

The roman numeral keys on the new keyboards will only be used as mouse
buttons if the "mode lock" key, located just below them, is latched down.

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:
