========================== C M U C L 20 e ============================= [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 * ASDF2 updated to version 2.28. * 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. * ANSI compliance fixes: * Bugfixes: * REPLACE and friends on strings was 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.) * Trac Tickets: * Ticket #52 reopened. * Ticket #66 fixed. * Ticket #67 fixed. * Ticket #68 fixed. * Ticket #69 fixed. * Ticket #70 fixed. * Ticket #65 fixed. * Ticket #71 fixed. * Ticket #72 fixed. * Other changes: * -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: This release is not binary compatible with code compiled using CMUCL 20d; you will need to recompile FASL files. See or for download information, guidelines on reporting bugs, and mailing list details. We hope you enjoy using this release of CMUCL!
