5 rtoy 1.2 The CMUCL project is pleased to announce the release of CMUCL 19b.
6 rtoy 1.1 This is a major release which contains numerous enhancements and
7 rtoy 1.2 bugfixes from the 19a 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     * Feature enhancements:
22 rtoy 1.3 - Added a much faster and much less consy bignum printer and a
23     faster bignum reader.
24     - Extended REQUIRE to support *MODULE-PROVIDER-FUNCTIONS* from
25     SBCL.
26 rtoy 1.6 - NetBSD supported.
27 rtoy 1.2 - SIMPLE-STREAM fixes:
28     o READ-SEQUENCE and WRITE-SEQUENCE for
29     signed-byte/unsigned-byte 8 streams.
30     o Memory-mapped file streams.
31 rtoy 1.4 - Large file support for Solaris, so CMUCL can handle files
32     larger than 2GB.
33 rtoy 1.6 - Support for Mac OS X.
34     - A much faster GCD implementation.
35     - A faster Karatsuba multiplier when the number of words of the
36     bignums is not a power of 2. (Break-even is still around 1500
37     bits, though.)
38     - New command-line switch -debug-lisp-search to show how lisp is
39     searching for its core file.
40 rtoy 1.7 - DEBUG-RETURN implemented which allows you to return a value
41     from function. Only enabled with DEBUG 3.
42     - Lazy sxhash on symbols implemented for ppc.
43 rtoy 1.1
44     * Numerous ANSI compliance fixes:
45 rtoy 1.3 - FILE-AUTHOR should signal errors appropriately.
46 rtoy 1.1 - CMUCL was computing the wrong value for some special functions
47     when the argument was on the branch cut for the function.
48     - MULTIPLE-VALUE-BIND accepts &REST and friends in the var list.
49     - When constructing logical pathnames, all components will be
50     automatically upcased. Needed for print/read consistency, and
51     fixes an issue with ASDF and logical pathnames.
52 rtoy 1.5 - Numerous fixes to the float printer, including a new float
53     printer.
54     - Justification (~< ~>) works better.
55     - ~V with the value of NIL in format strings is treated to mean
56     as if it weren't given at all, as specified by ANSI CL.
57     - Characters print consistently with ~:C and ~S.
58 rtoy 1.7 - Numerous bug fixes for pretty-printing and format strings.
59     - Pathnames are now printed with #P instead of #p.
60     - The types COMPLEX and (COMPLEX REAL) are the same now.
61     - UPGRADED-COMPLEX-PART-TYPE returns RATIONAL for integer types
62     now. (CMUCL doesn't really have a (COMPLEX INTEGER) type).
63     - When a pathname can't be printed readably, signal a
64     PRINT-NOT-READABLE condition
65 rtoy 1.1
66     * Numerous bugfixes:
67 rtoy 1.3 - FFLOOR and friends preserve the sign of the arg, so -0.0 is
68     returned for negative args.
69     - EXPT sometimes returne NaN instead of 1 when the power was 0.
70 rtoy 1.4 - Weak pointers don't have O(n^2) GC behavior anymore.
71 rtoy 1.6 - X11 authorization changes to solve problems seen with servers
72     that don't listen to TCP connection requests.
73 rtoy 1.7 - unix-read fix
74     - The compiler would give an error on deriving the result type
75     of RANDOM when the arg to RANDOM was a union type.
76     - "~*~" was not being parsed to mean a wildcard version.
77     - If a pathname has a version, but no name, we can't print it
78     readably.
79     - UNIX-GETPWUID implemented for Darwin. Needed for FILE-AUTHOR.
80     - The compiler no longer gives errors when deriving the result type of
81     coerce when converting a integer to a float that would not fit
82     in a float.
83     - Fix bug in reading from streams with element-type SIGNED-BYTE
84     for sizes greater than 32: positive numbers were incorrectly
85     being returned as negative.
86 rtoy 1.6
87 rtoy 1.1 * Other changes:
88    
89 rtoy 1.5 * Improvements to the PCL implementation of CLOS:
90 rtoy 1.1
91     * Improvements to Hemlock, the Emacs-like editor:
92    
93     * Changes to rebuilding procedure:
94    
95     * Deprecated features:
96    
97     This release is not binary compatible with code compiled using CMUCL
98     19a; you will need to recompile FASL files.
