as per Daniel Barlow's suggestion and Martin Atzmueller's patch
changes in sbcl-0.6.12 relative to sbcl-0.6.11:
+* 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
-?? 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
+* fixed bug 13: Floating point infinities are now supported again.
+* 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.)
+* 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!)
-?? unscrewed floating point infinities (bug 13) in order to support
- :PROPAGATE-FLOAT-TYPE and :PROPAGATE-FUN-TYPE features
-?? some minor ANSIfication of type specifications: bare 'AND and 'OR
- are no longer valid type specifiers, so e.g. (TYPEP 11 'AND) now
- signals an error; and SATISFIES requires its predicate to be a
- symbol, not a function object
+* 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
* 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)
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.
