5 The CMUCL project is pleased to announce the release of CMUCL 19a.
6 This is a major release which contains numerous enhancements and
7 bugfixes from the 18e 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 * Feature enhancements:
22 - Stack overflow checking added for FreeBSD/x86 and Linux/x86.
23 - LISP:FIND-CLASS and LISP:CLASS-OF now return CLOS classes. The
24 symbols LISP:STANDARD-CLASS, LISP:BUILT-IN-CLASS, and
25 LISP:STRUCTURE-CLASS name CLOS classes. It is no longer
26 necessary to SHADOWING-IMPORT these from PCL when doing MOP
27 programming, and it fixes some non-compliances as well.
28 - Weak hash tables have been added for x86 systems.
29 - Local functions are now named (FLET <name> ...) or
30 (LABELS <name> ...).
31 - Compiler checking control string and number of args to FORMAT.
32 - TRACE automatically using encapsulation when function-end
33 breakpoints cannot be used.
34 - INSPECT working on CLOS instances.
35
36 * Numerous ANSI compliance fixes:
37 - Many bugs in CMUCL's type system detected by Paul Dietz'
38 ANSI test suite have been fixed.
39 - Non-keyword keyword names in lambda lists are now accepted.
40 - Condition slot initialization fixed for the case that two
41 or more slots have the same :INITARG.
42 - Initforms are now evaluated once only during condition slot
43 initialization.
44 - USE-VALUE, STORE-VALUE, CONTINUE behavior corrected in presence
45 of multiple restarts having the same name.
46 - RESTART-CASE's interaction with local macros fixed.
47 - Interaction of COMPUTE-RESTARTS and RESTART-CASE fixed in
48 presence of multiple restarts having the same name.
49 - Condition slot readers/writers are generic functions.
50 - &WHOLE, &REST, &BODY in macro lambda lists can be followed
51 by destructuring patterns. The previous behavior of &BODY
52 when followed by (<body> <declarations> <doc>) is available
53 through the new lambda-list keyword EXT:&PARSE-BODY.
54 - ELT now signals an error in safe code when used on lists
55 with an out-of-bounds index.
56 - Accessing arrays in compiled code with out-of-bounds indices
57 now signals a TYPE-ERROR.
58 - DECLARE no longer being a special operator.
59 - DEFINE-CONDITION accepts slot option :DOCUMENTATION.
60 - Behavior of (... &KEY &ALLOW-OTHER-KEYS) fixed for
61 DESTRUCTURING-BIND and macros.
62 - Stricter checking of keyword argument list in CLOS methods.
63 - &ENVIRONMENT variable bound bound before other vars, regardless
64 of where it appears in a lambda-list.
65 - VALUES types no longer accepting &KEY or &ALLOW-OTHER-KEYS.
66 - THE conforming to ANSI.
67 - SLOT-EXISTS-P can be used with conditions.
68
69 * Numerous bugfixes:
70 - NSET-EXCLUSIVE-OR returns the same results as SET-EXCLUSIVE-OR
71 wrt to duplicate elements.
72 - Forms like (MULTIPLE-VALUE-BIND 'LIST) no longer trapping
73 an internal compiler error when compiled.
74 - PARSE-INTEGER signaling PARSE-ERROR.
75 - Compiler eliminating some type checks in safe code.
76
77 * Other changes:
78 - Removed obsolete alias from MAKE-VECTOR to MAKE-ARRAY
79
80 * Numerous improvements to the PCL implementation of CLOS:
81 - Gerd's PCL has been added, which fixes numerous bugs and ANSI/
82 AMOP non-compliances, and adds various new optimizations (also
83 see the CMU User Manual).
84 - PCL's class hierarchy has been changed to conform to AMOP, for
85 instance, GENERIC-FUNCTION is now a subclass of
86 STANDARD-OBJECT.
87 - ENSURE-CLASS-USING-CLASS's argument list has been changed
88 to conform to AMOP.
89 - COMPUTE-EFFECTIVE-SLOT-DEFINITION now takes a slot name as
90 argument, for AMOP compliance.
91 - SUBTYPEP works in presence of forward-referenced classes.
92 - Accessing slots of specialized parameters in (SETF
93 SLOT-VALUE-USING-CLASS) methods works.
94 - DIRECT-SLOT-DEFINITION-CLASS and EFFECTIVE-SLOT-DEFINITION-CLASS
95 AMOP compliant.
96 - ALLOCATE-INSTANCE working with structures defined with DEFSTRUCT.
97 - With (DEFGENERIC FOO (&REST X &KEY)) (DEFMETHOD FOO (&REST X) X),
98 (FOO 1) now signals an error.
99
100 * Improvements to Hemlock, the Emacs-like editor:
101
102 * Changes to rebuilding procedure:
103
104 * Deprecated features:
105
106
107 This release is not binary compatible with code compiled using CMUCL
108 18e; you will need to recompile FASL files.
