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:STARDARD-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
32 * Numerous ANSI compliance fixes:
33 - Many bugs in CMUCL's type system detected by Paul Dietz'
34 ANSI test suite have been fixed.
35 - Non-keyword keyword names in lambda lists are now accepted.
36 - Condition slot initialization fixed for the case that two
37 or more slots have the same :INITARG.
38 - Initforms are now evaluated once only during condition slot
39 initialization.
40 - USE-VALUE, STORE-VALUE, CONTINUE behavior corrected in presence
41 of multiple restarts having the same name.
42 - RESTART-CASE's interaction with local macros fixed.
43 - Interaction of COMPUTE-RESTARTS and RESTART-CASE fixed in
44 presence of multiple restarts having the same name.
45 - Condition slot readers/writers are generic functions.
46 - &WHOLE, &REST, &BODY in macro lambda lists can be followed
47 by destructuring patterns. The previous behavior of &BODY
48 when followed by (<body> <declarations> <doc>) is available
49 through the new lambda-list keyword EXT:&PARSE-BODY.
50 - ELT now signals an error in safe code when used on lists
51 with an out-of-bounds index.
52 - Accessing arrays in compiled code with out-of-bounds indices
53 now signals a TYPE-ERROR.
54 - DECLARE no longer being a special operator.
55
56 * Numerous bugfixes:
57 - NSET-EXCLUSIVE-OR returns the same results as SET-EXCLUSIVE-OR
58 wrt to duplicate elements.
59 - Forms like (MULTIPLE-VALUE-BIND 'LIST) no longer trapping
60 an internal compiler error when compiled.
61
62 * Other changes:
63
64 * Numerous improvements to the PCL implementation of CLOS:
65 - Gerd's PCL has been added, which fixes numerous bugs and ANSI/
66 AMOP non-compliances, and adds various new optimizations (also
67 see the CMU User Manual).
68 - PCL's class hierarchy has been changed to conform to AMOP, for
69 instance, GENERIC-FUNCTION is now a subclass of
70 STANDARD-OBJECT.
71 - ENSURE-CLASS-USING-CLASS's argument list has been changed
72 to conform to AMOP.
73 - COMPUTE-EFFECTIVE-SLOT-DEFINITION now takes a slot name as
74 argument, for AMOP compliance.
75 - SUBTYPEP works in presence of forward-referenced classes.
76 - Accessing slots of specialized parameters in (SETF
77 SLOT-VALUE-USING-CLASS) methods works.
78 - DIRECT-SLOT-DEFINITION-CLASS and EFFECTIVE-SLOT-DEFINITION-CLASS
79 AMOP compliant.
80 - ALLOCATE-INSTANCE working with structures defined with DEFSTRUCT.
81
82 * Improvements to Hemlock, the Emacs-like editor:
83
84 * Changes to rebuilding procedure:
85
86 * Deprecated features:
87
88
89 This release is not binary compatible with code compiled using CMUCL
90 18e; you will need to recompile FASL files.
