[In Progress]
The CMUCL project is pleased to announce the release of CMUCL 20e.
This is a major release which contains numerous enhancements and
bug fixes from the 20c 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 multi-methods and a meta-object 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 mostly in the public domain.
New in this release:
* Known issues:
* Feature enhancements
* Changes
* DEFINE-COMPILER-MACRO now has source-location information for
the macro definition.
* :ALIEN-CALLBACK added to *FEATURES* for platforms that support
alien callbacks.
* The sparc port can be built using gcc once again.
* The old Cheney stop-and-copy GC supported on sparc once again.
However, there are no plans on supplying sparc binaries with
this GC.
* For x86, optimize TRUNCATE when the second arg is a compile-time
constant and use a multiplication instead of a division. (Sparc
and ppc already had this optimization)
* The following *FEATURES* have been removed:
* :COMMON (not used)
* :CONSERVATIVE-FLOAT-TYPE (Always default to this in type
derivation.)
* :I486 and :PENTIUM (Always assume we're running on at least a
Pentium.)
* Add MP:PROCESS-JOIN, as given in ticket #77.
* Attempts to modify the standard readtable or the standard pprint
dispatch table will now signal a continuable error.
* REPLACE and friends on strings were limited to strings less than
the maximum possible size. This has been fixed so strings of any
supported length can be handled. (See ticket #66 and #68.)
* A serious error in FILE-POSITION on streams using an encoding
other than latin1 has been fixed. See ticket #74.
* Fix startup crashes on some Debian Linux versions. This was
caused by the release string not having a patch version.
* Ticket #66 fixed.
* Ticket #67 fixed.
* Ticket #68 fixed.
* Ticket #74 fixed.
* -8 option for build-all.sh is deprecated since we don't
officially support 8-bit builds anymore.
* Some small updates to the User Manual and CMU Internals
documents to generate pdf files by default.
* Improvements to the PCL implementation of CLOS:
* Changes to building procedure:
* In make-dist.sh, the version is now optional. If not given, a
version is derived from the git hash returned by "git
describe".
This release is not binary compatible with code compiled using CMUCL
20d; you will need to recompile FASL files.

We hope you enjoy using this release of CMUCL!
