The return value from CL:FIND-CLASS + is now a CLOS class, and likewise that of CL:CLASS-OF; + CL:BUILT-IN-CLASS, CL:STRUCTURE-CLASS and CL:STANDARD-CLASS name + CLOS classes. + * An interface to the MetaObject Protocol, as described in Kiczales, + des Rivieres and Bobrow's "The Art of the Metaobject Protocol", + MIT Press, 1991, is available from the SB-MOP package. + * incompatible change: the SB-PCL package should now be considered a + private implementation detail, and no longer a semi-private MOP + interface. + * minor incompatible change: due to rearrangement for threads, the + control stack and binding stack are now allocated at arbitrary + addresses instead of being hardcoded per-port. Users affected by + this probably have to be doing advanced things with shared + libraries, and will know who they are. + * minor incompatible change: Previously, all --eval forms used were + processed with READ before any of them were processed with EVAL. + Now each --eval form is processed with both READ and EVAL before + the next --eval form is processed. (Thus package operations like + sbcl --eval "(defpackage :foo)" --eval "(print 'foo::bar)" now work + as the user might reasonably expect.) + * minor incompatible change: *STANDARD-INPUT* is now only an + INPUT-STREAM, not a BIDIRECTIONAL-STREAM. (thanks to Antonio + Martinez) + * minor incompatible change: Y-OR-N-P is now character-oriented, not + line oriented. Also, YES-OR-NO-P now works without errors. + (thanks to Antonio Martinez) + * known functions, which cannot be open coded by backend, are + considered to be able to check types of their arguments. + (reported by Nathan J. Froyd) + * fixed a bug in computing method discriminating functions: it is + now possible to define methods specialized on classes which have + forward-referenced superclasses.

(reported by Gilbert + Baumann) + * SB-MOP:ENSURE-CLASS-USING-CLASS now takes its arguments in the + specified-by-AMOP order of (CLASS NAME &REST ARGS &KEY). + * SB-MOP:COMPUTE-EFFECTIVE-SLOT-DEFINITION now takes the + required-by-AMOP NAME argument, as well as CLASS and + DIRECT-SLOT-DEFINITIONS. (thanks to Kevin Rosenberg) + * fixed bug 20: DEFMETHOD can define methods using names that are + not the proper names of classes to designate class specializers. + * bug fix: INTERACTIVE-STREAM-P now works on streams associated with + Unix file descriptors, instead of blowing up. (thanks to Antonio + Martinez) + * Experimental native threads support, on x86 Linux. This is not + compiled in by default: you need to add :SB-THREAD to the target + features. See the "Beyond ANSI" chapter of the manual for + details. + * Garbage collection refactoring: user-visible change is that a + call to the GC function during WITHOUT-GCING will not do garbage + collection until the end of the WITHOUT-GCING. If you were doing + this you were probably losing anyway. + * sb-aclrepl module improvements: an integrated inspector, added + repl features, and a bug fix to :trace command. + * fixed bug in MEMBER type: (MEMBER 0.0) is not the same as + (SINGLE-FLOAT 0.0 0.0), because of the existence of -0.0 which is + TYPEP the latter but not the former. + * compiler issues a full WARNING on calling of an undefined function + with a name from the CL package. + * MAP-INTO for a vector destination is open coded.
