as per Daniel Barlow's suggestion and Martin Atzmueller's patch
changes in sbcl-0.6.12 relative to sbcl-0.6.11:
-?? many patches ported from CMU CL by Martin Atzmueller, notably
- ??
- ??
-?? new fasl file format version number (because a disused byte code
- opcode was removed, causing the other opcodes to change)
-* various tweaks to make the system easier to build under other
+* incompatible change: The old SB-EXT:OPTIMIZE-INTERFACE declaration
+ is no longer recognized. I apologize for this, because it was
+ listed in SB-EXT as a supported extension, but I found that
+ its existing behavior was poorly specified, as well as incorrectly
+ specified, and it looked like too much of a mess to straighten it
+ out. I have enough on my hands trying to get ANSI stuff to work..
+* many patches ported from CMU CL by Martin Atzmueller, with
+ half a dozen bug fixes in pretty-printing and the debugger, and
+ half a dozen others elsewhere
+* fixed bug 13: Floating point infinities are now supported again.
+ They might still be a little bit flaky, but thanks to bug reports
+ from Nathan Froyd and CMU CL patches from Raymond Toy they're not
+ as flaky as they were.
+* The --noprogrammer command line option is now supported. (Its
+ behavior is slightly different in detail from what the old man
+ page claimed it would do, but it's still appropriate under the
+ same circumstances that the man page talks about.)
+* The :SB-PROPAGATE-FLOAT-TYPE and :SB-PROPAGATE-FUN-TYPE features
+ are now supported, and enabled by default. Thus, the compiler can
+ handle many floating point and complex operations much less
+ inefficiently. (Thus e.g. you can implement a complex FFT
+ without consing!)
+* The compiler now detects type mismatches between DECLAIM FTYPE
+ and DEFUN better, and implements CHECK-TYPE more correctly, and
+ SBCL builds under CMU CL again despite its non-ANSI EVAL-WHEN,
+ thanks to patches from Martin Atzmueller.
+* various fixes to make the cross-compiler more portable to
ANSI-conforming-but-different cross-compilation hosts (notably
Lispworks for Windows, following bug reports from Arthur Lemmens)
-?? The :PROPAGATE-FLOAT-TYPE and :PROPAGATE-FUN-TYPE target features
- are now enabled by default. Now the compiler can handle many
- floating point and complex operations much less inefficiently.
- (Thus e.g. you can implement a complex FFT without consing!)
+* A bug in READ-SEQUENCE for CONCATENATED-STREAM, and a gross
+ ANSI noncompliance in DEFMACRO &KEY argument parsing, have been
+ fixed thanks to Pierre Mai's CMU CL patches.
+* fixes to keep the system from overflowing internal counters when
+ it tries to use i/o buffers larger than 16M bytes
+* fixed bug 45a: Various internal functions required to support
+ complex special functions have been merged from CMU CL sources.
+ (When I was first setting up SBCL, I misunderstood a compile-time
+ conditional #-OLD-SPECFUN, and so accidentally deleted them.)
+* improved support for type intersection and union, fixing bug 12
+ (e.g., now (SUBTYPEP 'KEYWORD 'SYMBOL)=>T,T) and some other
+ more obscure bugs as well
+* some steps toward byte-compiling non-performance-critical
+ parts of the system, courtesy of patches from Martin Atzmueller
+* Christophe Rhodes has made some debian packages of sbcl at
+ <http://www-jcsu.jesus.cam.ac.uk/ftp/pub/debian/lisp>.
+ From his sbcl-devel e-mail of 2001-04-08 they're not completely
+ stable, but are nonetheless usable. When he's ready, I'd be happy
+ to add them to the SourceForge "File Releases" section. (And if
+ anyone wants to do RPMs or *BSD packages, they'd be welcome too.)
+* new fasl file format version number (because of changes in
+ internal representation of (OR ..) types to accommodate the new
+ support for (AND ..) types, among other things)
planned incompatible changes in 0.7.x:
* The debugger prompt sequence now goes "5]", "5[2]", "5[3]", etc.
e.g. UNPROFILE will interact with TRACE and UNTRACE. (This shouldn't
matter, though, unless you are using profiling. If you never
profile anything, TRACE should continue to behave as before.)
+* The fasl file extension may change, perhaps to ".fasl".
+* The default output representation for unprintable ASCII characters
+ which, unlike e.g. #\Newline, don't have names defined in the
+ ANSI Common Lisp standard, may change to their ASCII symbolic
+ names: #\Nul, #\Soh, #\Stx, etc.
+* INTERNAL-TIME-UNITS-PER-SECOND might increase, e.g. to 1000.
+* MAYBE-INLINE will probably go away at some point, maybe 0.7.x,
+ maybe later, in favor of the ANSI-recommended idiom for making
+ a function optionally inline.
+* FASL file extensions change to ".fasl", instead of the various
+ CPU-dependent values (".x86f" etc.) inherited from CMU CL.
