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 rtoy 1.6.2.4 - Updated network support:
25     o Added BIND-INET-SOCKET to bind a socket to a local address.
26     o Added OPEN-NETWORK-STREAM to create a stream connected to a given host.
27     o Added ACCEPT-NETWORK-STREAM to create a stream connected to
28     the new network connection
29     o Updated CONNECT-TO-INET-SOCKET to allow binding the newly
30     created socket to a local address
31    
32 rtoy 1.1 * ANSI compliance fixes:
33 rtoy 1.3 - Fix bug in backquote printer. If the variable is @foo, we want
34     to print ", @foo" not ",@foo". Similarly, for .foo, we want to
35     print ", .foo" instead of ",.foo".
36 rtoy 1.5 - Fix merging of version in MAKE-PATHNAME. If the pathname name
37     is given, the version is not affected by the version in the
38     default pathname.
39 rtoy 1.6.2.1 - RENAME-FILE now creates defaulted-new-name from merging new-name
40     with the original filespec. This is an incompatible change from
41     the previous version which created defaulted-new-name from
42     merging the new-name with the truename of filespec. Also, a
43     logical pathname should be returned if new-name is a logical
44     pathname.
45 rtoy 1.6.2.4 - Character names need to be a capital letter followed by lower
46     case. Needed to match what ~:C does. (Found via ansi-tests).
47 rtoy 1.1
48     * Bugfixes:
49 rtoy 1.3 - Compiler can now derive the rank of an array, even if the array
50     is not simple.
51     - Fix off-by-one bug in ~R which prevents printing numbers from
52     10^63 to 10^66-1. 10^63 is a vigintillion.
53     - The compiler and interpreter should now handle slot-value the
54     same. Previously, different results were returned for things
55     like (slot-value foo :a).
56 rtoy 1.4 - UNIX-GETGRNAM is now defined for Darwin (x86 and ppc).
57 rtoy 1.5 - UNIX-GETPWUID is defined for all BSD systems.
58     - Type-derivation for EXPT no longer causes errors in some
59     situations. The computed bounds were of the wrong type for the
60     resulting type specifier.
61     - Pathname printer no longer produces an error for (MAKE-PATHNAME
62     :HOST NIL :TYPE "foo"). It returns #P(:HOST NIL :TYPE "foo")
63     now.
64     - Type derivation for DOUBLE-DOUBLE-FLOAT arithmetic should be
65     working. Previously, all arithmetic operations would just
66     return DOUBLE-DOUBLE-FLOAT even though the compiler should have
67     been able to figure out a tighter result.
68 rtoy 1.6 - When SCALE-FLOAT would underflow, it would always return 0f0,
69     instead of a floating-point zero of the correct type.
70 rtoy 1.6.2.1 - Fix some issues in creating the debug arglist string when the
71     arglist contains items that can't be printed readably.
72 rtoy 1.6.2.2 - DIRECTORY is now faster for directories with a large number of
73     files.
74 rtoy 1.6.2.3 - RANDOM is now much faster on all platforms for numbers upto
75     #xffffffff. This is an incompatible change from previous
76     releases because the numbers produced may be different from
77     before.
78     - The small bias in RANDOM for integer args up to 32 bits long
79     should now be gone.
80 rtoy 1.6.2.4 - Improved type derivation for LOGAND when one arg is bounded but
81     the other is not.
82 rtoy 1.1
83     * Trac Tickets:
84 rtoy 1.6 - #16: Read-time hash-table issue
85     Fixed.
86 rtoy 1.6.2.4 - #17: LOOP NAMED NIL has no effect
87     Fixed.
88     - #18: Modular arith bug 1
89     Fixed
90     - #19: Modular arith bug 2
91     Fixed by not doing modular arith if the args are known to be
92     fixnums.
93     - #20: Modular arith bug?
94     Workaround applied.
95 rtoy 1.1
96     * Other changes:
97 rtoy 1.6.2.3 - IS1, IS2, IS3, and IS4 are recognized character names for the
98     ASCII control codes US, RS, GS, FS, respectively.
99     - Added OPEN-NETWORK-STREAM and ACCEPT-NETWORK-STREAM functions.
100 rtoy 1.6.2.4 - When initializing a random state, try to read 627 words from
101     /dev/urandom to initialize the entire state vector with random
102     bits. Previously, only one word was read.
103     - A seed of 0 is allowed in KERNEL:INIT-RANDOM-STATE.
104    
105 rtoy 1.1 * Improvements to the PCL implementation of CLOS:
106 rtoy 1.5 - The compiler and interpreter should handle SLOT-VALUE the same
107     way. Previously, (SLOT-VALUE obj :a) would behave differently
108     in the compiler and interpreter.
109 rtoy 1.6.2.1 - Some issues with get-accessor-method-function and
110     slot-value-using-class have been fixed.
111     Get-accessor-method-function was causing an error to be signaled
112     incorrectly.
113 rtoy 1.1
114 rtoy 1.3 * Changes to building procedure:
115 rtoy 1.1
116     This release is not binary compatible with code compiled using CMUCL
117 rtoy 1.3 19e; you will need to recompile FASL files.
118 rtoy 1.1
119     See <URL:http://www.cons.org/cmucl/> for download information,
120     guidelines on reporting bugs, and mailing list details.
121    
122    
123     We hope you enjoy using this release of CMUCL!
