These notes correspond to *pcl-system-date* "4/21/87 April 21rst 1987".
The notes from the last release are stored as 3-19-notes.text
This release runs in:
ExCL
Lucid
Symbolics Common Lisp (Genera)
Vaxlisp (2.0)
Xerox Common Lisp (Lyric Release)
Kyoto Common Lisp (5.2)
CMU Lisp (nee Spice) should be working soon, I will announce another
release at that time.
Xerox Lisp users should FTP all the source files from /pub/pcl/ as well
as all the dfasl files from /pub/pcl/xerox/. Included in the xerox
specific directory is a file called PCL-ENV, which provides some simple
environment support for using PCL in Xerox Lisp.
The major difference in this release is that defclass conforms to the
CLOS specification (pretty much I hope). Previous warnings about what
would happen when defclass became CLOS defclass now apply. Once major
difference is that PCL currently does require that all a classes
superclasses be defined when a defclass form is evaluated. This will
change sometime soon.
Other small changes include:
Some more of the files have been renamed and restructured (as promised).
the defclass parsing protocol has changed
slotd datastructures are now instances of the class
standard-slot-description.
a performance bug in the ExCL port which causes method lookup and slot
access to cons needlessly.
a bug in the 3600 port which broke the printer for stack consed closures
make-specializable
a bug in Lucid lisp which made it impossible to say (compile-pcl) has
been patched around, this is the bug that manifested itself as NAME
being ubound.
As usual, please enjoy and send comments.
