4    
5     The CMUCL project is pleased to announce the release of CMUCL 19c.
6     This is a major release which contains numerous enhancements and
7     bugfixes from the 19a release.
8    
9     CMUCL is a free, high performance implementation of the Common Lisp
10     programming language which runs on most major Unix platforms. It
11     mainly conforms to the ANSI Common Lisp standard. CMUCL provides a
12     sophisticated native code compiler; a powerful foreign function
13     interface; an implementation of CLOS, the Common Lisp Object System,
14     which includes multimethods and a metaobject protocol; a source-level
15     debugger and code profiler; and an Emacs-like editor implemented in
16     Common Lisp. CMUCL is maintained by a team of volunteers collaborating
17     over the Internet, and is mostly in the public domain.
18    
19     New in this release:
20    
21    
22     * Feature enhancements:
23    
24     - Cross-reference information can now be saved to a fasl file.
25     - COMPILE-FILE accepts the new keyword arg :XREF. When non-NIL,
26     cross-reference information found during compilation is saved
27     to the fasl file.
28 rtoy 1.4 - UNIX-UNAME added for non-glibc2 platforms, which already had
29     it.
30 rtoy 1.1
31     * Numerous ANSI compliance fixes:
32 rtoy 1.5
33 rtoy 1.2 - FILE-POSITION on string input streams accept :START and :END
34     for the position.
35 rtoy 1.4 - The default value for keyword args for deftype is '*, not NIL.
36     - ED is now defined (but does nothing). Loading hemlock will
37     give you an ED that works.
38     - DOCUMENTATION and (SETF DOCUMENTATION) works for more cases
39     now.
40     - MULTIPLE-VALUE-SETQ now always returns the primary value.
41     - (SETF MACRO-FUNCTION) and (SETF COMPILER-MACRO-FUNCTION)
42     accepts the optional environment arg, as specified by ANSI CL.
43    
44 rtoy 1.1 * Numerous bugfixes:
45 rtoy 1.5
46 rtoy 1.3 - Regression in MRG32K3A benchmark fixed.
47     - (format t "~8,2f" -0.0) has the right length now. This
48     happened because we didn't recognize -0.0 is negative.
49 rtoy 1.4 - Type derivation for FTRUNCATE is now consistent with what
50     FTRUNCATE returns. Main problem was that -0.0 is now returned
51     by ftruncate instead of +0.0.
52     - Some errors during type derivation are fixed. We cause the
53     offending function to return NIL to indicate unbounded.
54 rtoy 1.1
55    
56     * Other changes:
57 rtoy 1.5
58     - Due to some bugs in modular arithmetic, generating either
59     wrong code or much slower code, you can now disable modular
60     arithmetic by setting c::*enable-modular-arithmetic* to NIL.
61     This is a workaround pending a better solution.
62    
63 rtoy 1.1
64     * Improvements to the PCL implementation of CLOS:
65    
66     * Changes to rebuilding procedure:
67 rtoy 1.4 - Build scripts should recognize FreeBSD automatically.
68 rtoy 1.1
69    
70     This release is not binary compatible with code compiled using CMUCL
71     19b; you will need to recompile FASL files.
72    
73     See <URL:http://www.cons.org/cmucl/> for download information,
74     guidelines on reporting bugs, and mailing list details.
75    
76    
77     We hope you enjoy using this release of CMUCL!
