1 rtoy 1.1 ========================== C M U C L 19 d =============================
2    
3     [--- WORK IN PROGRESS --- DO NOT DISTRIBUTE ---]
4    
5     The CMUCL project is pleased to announce the release of CMUCL 19d.
6     This is a major release which contains numerous enhancements and
7 emarsden 1.4 bugfixes from the 19c release.
8 rtoy 1.1
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     - Destructive functions like nreverse that modify constant args
25     will produce a warning.
26     - Destructive functions like nreverse whose results are not used
27     will produce a warning.
28     - Pathnames that cannot be printed readably using #p"..." will
29     now be printed using the CMUCL extension #P(...). However,
30     there are still cases where CMUCL cannot print pathnames
31     readably, but these involve search-lists and patterns.
32 rtoy 1.3 - LONG-LONG and UNSIGNED-LONG-LONG are recognized types in the
33     C-CALL package for signed and unsigned 64-bit integers.
34 rtoy 1.5 - A port of gencgc to Darwin/ppc has been made. This still
35     needs work, and is known to have some issues.
36 rtoy 1.8 - TRACE supports tracing of FLET/LABELS functions. Use (trace
37     (labels foo bar)) to trace the labels function FOO in the
38     function BAR. This is currently experimental.
39 rtoy 1.1
40     * Numerous ANSI compliance fixes:
41    
42     - A reader-error is signaled if the number that is being read is
43     too small to be presented. We used to silently return 0.
44     - WITH-INPUT-FROM-STRING no longer modifies the index if
45     WITH-INPUT-FROM-STRING is not exited normally.
46     - An error is signaled if a declaration is used as the name of a
47     deftype, condition, or defstruct, and vice versa.
48     - An error is signaled when trying to generate a namestring from
49     a pathname with just a version component (other than nil,
50     :newest, or :unspecific). CMUCL cannot print that readably.
51     - FLET and LABELS functions will catch errors in keyword
52     parameters. Previously, a keyword of NIL was silently
53     accepted.
54     - Printing a zero using ~E will now include a trailing zero
55     after the decimal point, as required by CLHS, 22.3.3.2.
56 rtoy 1.2 - DOCUMENTATION and (SETF DOCUMENTATION) now works for
57     structures of type list or vector.
58 rtoy 1.3 - DOTIMES will execute the loop the specified number of times,
59     independent of what the loop might do to the loop counter.
60 rtoy 1.1
61     * Numerous bugfixes:
62    
63     - LISTEN on DUAL-CHANNEL-SIMPLE-STREAM should work now.
64     - Some numerical issues with the two-arg log function have been
65     fixed. (log 17 10f0), (log 17f0 10) and (log 17 10) all
66     return the same result now.
67     - DESTRUCTURING-BIND no longer causes an error when the list to
68     be destructured is circular.
69 rtoy 1.2 - PEEK-CHAR for Gray streams handles end of file correctly now.
70     - For the ppc port, the alignment of objects in alien structures
71     now matches the PowerOpen ABI for Mac OS X.
72 rtoy 1.3 - For Darwin/ppc, CMUCL was not following the ABI when calling
73     out to C varargs functions. Now we always copy any float args
74     to the corresponding int regs (or stack) as required by the
75     ABI. This isn't necessary for non-varargs functions, but
76     CMUCL doesn't know functions which are varargs functions.
77     - Callbacks with long-long args or results should work correctly
78     now for Darwin/ppc.
79 rtoy 1.5 - DESCRIBE no longer depends on having PCL loaded.
80     - Tracing with no encapsulation appears to be working now for
81     ppc.
82     - A simple interface to sysinfo(2) has been added for sparc.
83     This is used to provide better values for MACHINE-TYPE and
84     MACHINE-VERSION.
85 rtoy 1.6 - PARSE-TIME can parse times like "Tue Sep 7 18:56:57 UTC 2004"
86     again.
87     - The pretty-printer for MULTIPLE-VALUE-BIND can handle
88 rtoy 1.9 malformed MULTIPLE-VALUE-BIND forms now, instead of producing
89 rtoy 1.6 an error.
90 rtoy 1.7 - Callbacks on Darwin/ppc with a large number of args (more than
91     8 integer args) should work correctly now. (Previous versions
92     would signal an error.)
93 rtoy 1.9 - DESCRIBE no longer says arrays are adjustable when they are
94     not, and vice versa.
95     - Disassembly of some floating-point instructions on ppc has
96     been corrected to display floating-point registers instead of
97     integer registers.
98 rtoy 1.1
99     * Other changes:
100    
101     - CMUCL catches more cases where it cannot print a pathname
102     readably. In particular when the pathname name contains "/"
103     or ".", or when the pathname type contains a ".".
104 rtoy 1.6 - WITH-SLOTS and WITH-ACCESSORS are now pprinted like
105     MULTIPLE-VALUE-BIND instead of like WITH-OPEN-FILE.
106 rtoy 1.1
107     * Improvements to the PCL implementation of CLOS:
108    
109     * Changes to rebuilding procedure:
110     - Build scripts should recognize FreeBSD automatically.
111     - Should be able to build on either Mac OS X 10.2 or 10.4 using
112     the default version of gcc.
113    
114     This release is not binary compatible with code compiled using CMUCL
115 emarsden 1.4 19c; you will need to recompile FASL files.
116 rtoy 1.1

118     guidelines on reporting bugs, and mailing list details.

120    
121     We hope you enjoy using this release of CMUCL!
