1 rtoy 1.1 ========================== C M U C L 19 f =============================
2    
3     [--- WORK IN PROGRESS ---]
4    
5     The CMUCL project is pleased to announce the release of CMUCL 19f.
6     This is a major release which contains numerous enhancements and
7     bugfixes from the 19e 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 rtoy 1.6.2.3 - ~R supports many more cardinal names.
24    
25 rtoy 1.1 * ANSI compliance fixes:
26 rtoy 1.3 - Fix bug in backquote printer. If the variable is @foo, we want
27     to print ", @foo" not ",@foo". Similarly, for .foo, we want to
28     print ", .foo" instead of ",.foo".
29 rtoy 1.5 - Fix merging of version in MAKE-PATHNAME. If the pathname name
30     is given, the version is not affected by the version in the
31     default pathname.
32 rtoy 1.6.2.1 - RENAME-FILE now creates defaulted-new-name from merging new-name
33     with the original filespec. This is an incompatible change from
34     the previous version which created defaulted-new-name from
35     merging the new-name with the truename of filespec. Also, a
36     logical pathname should be returned if new-name is a logical
37     pathname.
38 rtoy 1.1
39     * Bugfixes:
40 rtoy 1.3 - Compiler can now derive the rank of an array, even if the array
41     is not simple.
42     - Fix off-by-one bug in ~R which prevents printing numbers from
43     10^63 to 10^66-1. 10^63 is a vigintillion.
44     - The compiler and interpreter should now handle slot-value the
45     same. Previously, different results were returned for things
46     like (slot-value foo :a).
47 rtoy 1.4 - UNIX-GETGRNAM is now defined for Darwin (x86 and ppc).
48 rtoy 1.5 - UNIX-GETPWUID is defined for all BSD systems.
49     - Type-derivation for EXPT no longer causes errors in some
50     situations. The computed bounds were of the wrong type for the
51     resulting type specifier.
52     - Pathname printer no longer produces an error for (MAKE-PATHNAME
53     :HOST NIL :TYPE "foo"). It returns #P(:HOST NIL :TYPE "foo")
54     now.
55     - Type derivation for DOUBLE-DOUBLE-FLOAT arithmetic should be
56     working. Previously, all arithmetic operations would just
57     return DOUBLE-DOUBLE-FLOAT even though the compiler should have
58     been able to figure out a tighter result.
59 rtoy 1.6 - When SCALE-FLOAT would underflow, it would always return 0f0,
60     instead of a floating-point zero of the correct type.
61 rtoy 1.6.2.1 - Fix some issues in creating the debug arglist string when the
62     arglist contains items that can't be printed readably.
63 rtoy 1.6.2.2 - DIRECTORY is now faster for directories with a large number of
64     files.
65 rtoy 1.6.2.3 - RANDOM is now much faster on all platforms for numbers upto
66     #xffffffff. This is an incompatible change from previous
67     releases because the numbers produced may be different from
68     before.
69     - The small bias in RANDOM for integer args up to 32 bits long
70     should now be gone.
71 rtoy 1.1
72     * Trac Tickets:
73 rtoy 1.6 - #16: Read-time hash-table issue
74     Fixed.
75 rtoy 1.1
76     * Other changes:
77 rtoy 1.6.2.3 - IS1, IS2, IS3, and IS4 are recognized character names for the
78     ASCII control codes US, RS, GS, FS, respectively.
79     - Added OPEN-NETWORK-STREAM and ACCEPT-NETWORK-STREAM functions.
80 rtoy 1.1
81     * Improvements to the PCL implementation of CLOS:
82 rtoy 1.5 - The compiler and interpreter should handle SLOT-VALUE the same
83     way. Previously, (SLOT-VALUE obj :a) would behave differently
84     in the compiler and interpreter.
85 rtoy 1.6.2.1 - Some issues with get-accessor-method-function and
86     slot-value-using-class have been fixed.
87     Get-accessor-method-function was causing an error to be signaled
88     incorrectly.
89 rtoy 1.1
90 rtoy 1.3 * Changes to building procedure:
91 rtoy 1.1
92     This release is not binary compatible with code compiled using CMUCL
93 rtoy 1.3 19e; you will need to recompile FASL files.
94 rtoy 1.1
95     See <URL:http://www.cons.org/cmucl/> for download information,
96     guidelines on reporting bugs, and mailing list details.
97    
98    
99     We hope you enjoy using this release of CMUCL!
