========================== C M U C L 20 d ============================= [Not yet released] The CMUCL project is pleased to announce the release of CMUCL 20d. 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 * Added a new contrib, "contrib-packed-sse2" to allow packed operations ala SSE2. Support for some packed sse2 operations like multiply, divide, and shuffle for both packed singles and doubles. All operatios are done on top of (complex double-float) numbers. Utility functions are provided to set and access these packed numbers. * Changes * ASDF2 updated to version 2.019. * Behavior of STRING-TO-OCTETS has changed. This is an incompatible change from the previous version but should be more useful when a buffer is given which is not large enough to hold all the octets for the given string. See docstring for more details. * The PowerPC port of CMUCL on Darwin (Mac OS X) has been revived and is up-to-date. It will run on OSX 10.4 and 10.5. However, only the Unicode build is supported. * Updated to Unicode 6.1.0. * ANSI compliance fixes: * CMUCL was not printing pathnames like (make-pathname :directory '(:absolute "tmp" "" "/")) correctly. This is now printed using #P(...). * Bugfixes: * DECODE-FLOAT was not correctly declared and could not be compiled to handle double-double-floats. * The source distribution now includes the scripts from the bin directory, which was previously missing. * The stack needs to be 16-byte aligned on Darwin. * ldb no longer prints prompts forever when EOF is reached. * LISP:UNICODE-COMPLETE now longer signals an error if the prefix isn't a prefix of the name of any unicode character. Nil is returned instead. * Some VOP costs were incorrect which prevented the fast complex double-float multiplier from being used when sse3 is available. * Trac Tickets: * #50: Print/read error with make-pathname. * #53: UTF-8 in core. * #52: UNICODE-COMPLETE-NAME misses a completion. * #55: blocked signals. * Other changes: * The layout of the cmucl directories has been changed. * On darwin/x86, gcc-4.2 is explicitly used in case Xcode 4 is installed. CMUCL doesn't run correctly when built with gcc/llvm in Xcode 4. * Add -R option to build.sh to force recompiling the C runtime. (Default it to compile only what is changed.) * Improvements to the PCL implementation of CLOS: * Changes to building procedure: This release is not binary compatible with code compiled using CMUCL 20c; you will need to recompile FASL files. See for download information, guidelines on reporting bugs, and mailing list details. We hope you enjoy using this release of CMUCL!
