5 The CMUCL project is pleased to announce the release of CMUCL 19e.
6 This is a major release which contains numerous enhancements and
7 bugfixes from the 19d 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.

19 New in this release:
20
21
22 * Feature enhancements:
23
24 * ANSI compliance fixes:
25 - BOA constructors with &AUX variables are handled better now.
26
27 * Bugfixes:
28 - Floating-point traps are now handled on ppc. Previously, no
29 traps were signalled and SET-FLOATING-POINT-MODES did nothing.
30 - FILE-POSITION no longer returns negative values for mapped
31 file-simple-stream's.
32 - Potential Version numbers that start with a leading 0 are not
33 treated as version numbers. Hence, "foo.~1~" has name "foo",
34 type nil, and version 1, but "foo.~01~" has type "~01~" and
35 version :NEWEST.
36 - Converting negative rationals to double-double-float's doesn't
37 produce wrong answers anymore.
38 * Trac Tickets:
39 - #8 fixed so logs of bignums and ratios that won't fit into a
40 float can be computed, instead of signalling an error.
41
42 * Other changes:
43
44 * Improvements to the PCL implementation of CLOS:
45 - Forward-referenced classes are allowed.
46
47 * Changes to rebuilding procedure:
48
49 This release is not binary compatible with code compiled using CMUCL
50 19d; you will need to recompile FASL files.
