========================== C M U C L 18 c =============================
December 25, 2000
The CMUCL project is pleased to announce the release of CMUCL 18c.
This is a major release which contains numerous enhancements and
bugfixes from the 18b release.
CMUCL is a free, high performance implementation of the Common Lisp
programming language which runs on most major Unix platforms. It
mainly conforms to the ANSI Common Lisp standard. CMUCL provides a
sophisticated native code compiler; a powerful foreign function
interface; an implementation of CLOS; the Common Lisp Object System;
which includes multimethods and a metaobject protocol; a source-level
debugger and code profiler; and an Emacs-like editor implemented in
Common Lisp. CMUCL is maintained by a team of volunteers collaborating
over the Internet, and is in the public domain.
Features new in this release:
o Every platform now supports (complex single-float) and (complex
double-float) (and long-float for the x86).
o Every platform now supports signed-array's with elements of type
(signed-byte 8), (signed-byte 16), (signed-byte 30), and
(signed-byte 32).
o On the x86 and sparc platform, much larger heaps are available.
o Support for glibc2 on x86.
o Support for FreeBSD 4.x, Solaris 2.7 & 8.
o Better support for Sparc V9 machines (UltraSparc II and later).
o Better handling of logical pathnames and pathnames in general.
o equalp hash tables implemented.
o New implementations of some sequence functions to run significantly
faster.
o Specialized arrays and various other objects can be printed readably
now, using a CMUCL extension.
o LOCALLY is a special form, not a macro.
o compiler-let is now in the extension package.
o PRINT-OBJECT methods can be used with structures. (But the
:print-object option to defstruct is still not accepted.)
o The dynamic heap size is now controllable from the command line with
the -dynamic-space-size option on the x86 and sparc ports.
o The -batch commandline option flushes all output on exit, and
causes exit upon error also when using -load.
o A new -quiet commandline to suppress informational messages.
o :cmu17 is no longer a *feature*. This may break existing code. A
simple possible workaround is to replace :cmu17 with (or :cmu17
:cmu18) everywhere in the offending code.
Some sparc-specific changes:
o Bigger spaces:
o 256 MB for read-only and static spaces
o 128 MB for binding and control stacks
o Upto 1 GB for the lisp heap. Default is 256 MB
o Added VOPS for complex single/double-float operations.
o Try not to use deprecated instructions in the V9 architecture.
o In certain situations, use conditional move instructions available
in the V9 architecture.
And finally,
o Lots and lots of bug fixes, improvements to ANSI CL conformance
and lots and lots of compiler enhancements.
This release is not binary compatible with code compiled using CMUCL
18b; you will need to recompile FASL files.

on reporting bugs, and mailing list details.
We hope you enjoy using this release of CMUCL!
