Corman Lisp 1.42 Release Notes

February 15, 2001

Changes and new features include:

Windows 2000 compatibility

In the GUI, this involved fixing some code that managed screen
highlighting in the editor (the rich text control changed in some
subtle way in Windows 2000).
Also, an error in the c-string/lisp-string conversion routine
was fixed, which didn't show up in OS's prior to Windows 2000
(or maybe it did, in some cases...)

Compiler changes:
Fixed MACROLET so that locally defined macros will be seen in
embedded lambdas.

Structure implementation change:
Modified structures to be integrated better with CLOS.
i.e. CLASS-OF returns a class unique to that structure type.
This means you can specialize methods on different structure types.

Incorporated all of Chris Double's patches from his web site.
Thanks a lot, Chris! You can see details at:
http://www.double.co.nz/cl

The CLOS EQL specializer fix is available by a switch, which
is off by default. You can change this in sys/load-sys2.lisp
(or in your own code by setting cl::*support-eql-specializers* to 
a non-nil value). It is off by default because it slows down 
method dispatching quite a bit.

Also from Chris:
SOCKETS package version 1.9
SSL-SOCKETS package (secure sockets)
Mark Meurer's SQL-ODBC package (Chris ported).
Mark Kantrowitz's LOGICAL-PATHNAMES package (Chris ported).
XMLRPC 1.1 package.

(with the exception of the Clos EQL specializer)

Example code:
Added IF* implementation
Added Bouncing example (bouncing ball).
