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
+* 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
+* improved support for intersection types, fixing bug 12 (E.g., now
+ (SUBTYPEP 'KEYWORD 'SYMBOL)=>T,T.)
+?? The :PROPAGATE-FLOAT-TYPE and :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!)
+?? unscrewed floating point infinities (bug 13) in order to support
+ :PROPAGATE-FLOAT-TYPE and :PROPAGATE-FUN-TYPE features
+* 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 new workaround to make the cross-compiler portable to CMU CL
+ again despite its non-ANSI EVAL-WHEN, thanks to Martin Atzmueller
+* new fasl file format version number (because of changes in byte
+ code opcodes and in internal representation of (OR ..) types)
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".
\ No newline at end of file
+* 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.
