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 emarsden 1.21 symbols LISP:STANDARD-CLASS, LISP:BUILT-IN-CLASS, and
25 gerd 1.3 LISP:STRUCTURE-CLASS name CLOS classes. It is no longer
26 gerd 1.1 necessary to SHADOWING-IMPORT these from PCL when doing MOP
27     programming, and it fixes some non-compliances as well.
28 gerd 1.2 - Weak hash tables have been added for x86 systems.
29 gerd 1.4 - Local functions are now named (FLET <name> ...) or
30     (LABELS <name> ...).
31 gerd 1.17 - Compiler checking control string and number of args to FORMAT.
32 gerd 1.1
33     * Numerous ANSI compliance fixes:
34 gerd 1.5 - Many bugs in CMUCL's type system detected by Paul Dietz'
35     ANSI test suite have been fixed.
36     - Non-keyword keyword names in lambda lists are now accepted.
37 gerd 1.6 - Condition slot initialization fixed for the case that two
38     or more slots have the same :INITARG.
39 gerd 1.7 - Initforms are now evaluated once only during condition slot
40     initialization.
41     - USE-VALUE, STORE-VALUE, CONTINUE behavior corrected in presence
42     of multiple restarts having the same name.
43     - RESTART-CASE's interaction with local macros fixed.
44     - Interaction of COMPUTE-RESTARTS and RESTART-CASE fixed in
45     presence of multiple restarts having the same name.
46 gerd 1.8 - Condition slot readers/writers are generic functions.
47 gerd 1.9 - &WHOLE, &REST, &BODY in macro lambda lists can be followed
48     by destructuring patterns. The previous behavior of &BODY
49     when followed by (<body> <declarations> <doc>) is available
50     through the new lambda-list keyword EXT:&PARSE-BODY.
51 gerd 1.10 - ELT now signals an error in safe code when used on lists
52     with an out-of-bounds index.
53     - Accessing arrays in compiled code with out-of-bounds indices
54     now signals a TYPE-ERROR.
55 gerd 1.11 - DECLARE no longer being a special operator.
56 gerd 1.16 - DEFINE-CONDITION accepts slot option :DOCUMENTATION.
57 gerd 1.18 - Behavior of (... &KEY &ALLOW-OTHER-KEYS) fixed for
58     DESTRUCTURING-BIND and macros.
59 gerd 1.19 - Stricter checking of keyword argument list in CLOS methods.
60 gerd 1.20 - &ENVIRONMENT variable bound bound before other vars, regardless
61     of where it appears in a lambda-list.
62 gerd 1.1
63     * Numerous bugfixes:
64 gerd 1.12 - NSET-EXCLUSIVE-OR returns the same results as SET-EXCLUSIVE-OR
65     wrt to duplicate elements.
66 gerd 1.11 - Forms like (MULTIPLE-VALUE-BIND 'LIST) no longer trapping
67     an internal compiler error when compiled.
68 gerd 1.16 - PARSE-INTEGER signaling PARSE-ERROR.
69     - Compiler eliminating some type checks in safe code.
70 gerd 1.1
71     * Other changes:
72 emarsden 1.21 - Removed obsolete alias from MAKE-VECTOR to MAKE-ARRAY
73 gerd 1.1
74     * Numerous improvements to the PCL implementation of CLOS:
75     - Gerd's PCL has been added, which fixes numerous bugs and ANSI/
76     AMOP non-compliances, and adds various new optimizations (also
77     see the CMU User Manual).
78 gerd 1.2 - PCL's class hierarchy has been changed to conform to AMOP, for
79     instance, GENERIC-FUNCTION is now a subclass of
80     STANDARD-OBJECT.
81 gerd 1.4 - ENSURE-CLASS-USING-CLASS's argument list has been changed
82     to conform to AMOP.
83 gerd 1.5 - COMPUTE-EFFECTIVE-SLOT-DEFINITION now takes a slot name as
84     argument, for AMOP compliance.
85 gerd 1.9 - SUBTYPEP works in presence of forward-referenced classes.
86 gerd 1.13 - Accessing slots of specialized parameters in (SETF
87     SLOT-VALUE-USING-CLASS) methods works.
88 gerd 1.14 - DIRECT-SLOT-DEFINITION-CLASS and EFFECTIVE-SLOT-DEFINITION-CLASS
89     AMOP compliant.
90 gerd 1.15 - ALLOCATE-INSTANCE working with structures defined with DEFSTRUCT.
91 gerd 1.1
92     * Improvements to Hemlock, the Emacs-like editor:
93    
94     * Changes to rebuilding procedure:
95    
96     * Deprecated features:
97    
98    
99     This release is not binary compatible with code compiled using CMUCL
100     18e; you will need to recompile FASL files.

103     guidelines on reporting bugs, and mailing list details.

106     We hope you enjoy using this release of CMUCL!
