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 rtoy 1.10 needs work, and is known to have some issues, but it compiles
36     CMUCL without problems and runs maxima just fine.
37 rtoy 1.8 - TRACE supports tracing of FLET/LABELS functions. Use (trace
38     (labels foo bar)) to trace the labels function FOO in the
39     function BAR. This is currently experimental.
40 rtoy 1.1
41     * Numerous ANSI compliance fixes:
42    
43     - A reader-error is signaled if the number that is being read is
44     too small to be presented. We used to silently return 0.
45     - WITH-INPUT-FROM-STRING no longer modifies the index if
46     WITH-INPUT-FROM-STRING is not exited normally.
47     - An error is signaled if a declaration is used as the name of a
48     deftype, condition, or defstruct, and vice versa.
49     - An error is signaled when trying to generate a namestring from
50     a pathname with just a version component (other than nil,
51     :newest, or :unspecific). CMUCL cannot print that readably.
52     - FLET and LABELS functions will catch errors in keyword
53     parameters. Previously, a keyword of NIL was silently
54     accepted.
55     - Printing a zero using ~E will now include a trailing zero
56     after the decimal point, as required by CLHS, 22.3.3.2.
57 rtoy 1.2 - DOCUMENTATION and (SETF DOCUMENTATION) now works for
58     structures of type list or vector.
59 rtoy 1.3 - DOTIMES will execute the loop the specified number of times,
60     independent of what the loop might do to the loop counter.
61 rtoy 1.1
62     * Numerous bugfixes:
63    
64     - LISTEN on DUAL-CHANNEL-SIMPLE-STREAM should work now.
65     - Some numerical issues with the two-arg log function have been
66     fixed. (log 17 10f0), (log 17f0 10) and (log 17 10) all
67     return the same result now.
68     - DESTRUCTURING-BIND no longer causes an error when the list to
69     be destructured is circular.
70 rtoy 1.2 - PEEK-CHAR for Gray streams handles end of file correctly now.
71     - For the ppc port, the alignment of objects in alien structures
72     now matches the PowerOpen ABI for Mac OS X.
73 rtoy 1.3 - For Darwin/ppc, CMUCL was not following the ABI when calling
74     out to C varargs functions. Now we always copy any float args
75     to the corresponding int regs (or stack) as required by the
76     ABI. This isn't necessary for non-varargs functions, but
77     CMUCL doesn't know functions which are varargs functions.
78     - Callbacks with long-long args or results should work correctly
79     now for Darwin/ppc.
80 rtoy 1.5 - DESCRIBE no longer depends on having PCL loaded.
81     - Tracing with no encapsulation appears to be working now for
82     ppc.
83     - A simple interface to sysinfo(2) has been added for sparc.
84     This is used to provide better values for MACHINE-TYPE and
85     MACHINE-VERSION.
86 rtoy 1.6 - PARSE-TIME can parse times like "Tue Sep 7 18:56:57 UTC 2004"
87     again.
88     - The pretty-printer for MULTIPLE-VALUE-BIND can handle
89 rtoy 1.9 malformed MULTIPLE-VALUE-BIND forms now, instead of producing
90 rtoy 1.6 an error.
91 rtoy 1.7 - Callbacks on Darwin/ppc with a large number of args (more than
92     8 integer args) should work correctly now. (Previous versions
93     would signal an error.)
94 rtoy 1.9 - DESCRIBE no longer says arrays are adjustable when they are
95     not, and vice versa.
96     - Disassembly of some floating-point instructions on ppc has
97     been corrected to display floating-point registers instead of
98     integer registers.
99 rtoy 1.1
100     * Other changes:
101    
102     - CMUCL catches more cases where it cannot print a pathname
103     readably. In particular when the pathname name contains "/"
104     or ".", or when the pathname type contains a ".".
105 rtoy 1.6 - WITH-SLOTS and WITH-ACCESSORS are now pprinted like
106     MULTIPLE-VALUE-BIND instead of like WITH-OPEN-FILE.
107 rtoy 1.1
108     * Improvements to the PCL implementation of CLOS:
109    
110     * Changes to rebuilding procedure:
111     - Build scripts should recognize FreeBSD automatically.
112     - Should be able to build on either Mac OS X 10.2 or 10.4 using
113     the default version of gcc.
114    
115     This release is not binary compatible with code compiled using CMUCL
116 emarsden 1.4 19c; you will need to recompile FASL files.
117 rtoy 1.1

119     guidelines on reporting bugs, and mailing list details.

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