* fixed bug 219: DEFINE-COMPILER-MACRO no longer has compile-time
effect when it is not in a toplevel context.
* fixed bug in COERCE, which now signals an error on coercing a

- * fixed some more bugs revealed by Paul Dietz' test suite:
+ * fixed bug 223: functional binding is considered to be constant
+ only for symbols in the CL package.
+ * fixed bug 231: SETQ did not check the type of a variable being set
+ (reported by Robert E. Brown)
+ * A new optimization for MAKE-INSTANCE has been included, fixing
+ various bugs (including relating to :ALLOCATION :CLASS slots and
+ :DEFAULT-INITARGS over-eager evalueation). (thanks to Gerd

+ * fixed some LOOP bugs revealed by Paul Dietz' test suite:
** As required by ANSI, LOOP now disallows anonymous collection
clauses such as COLLECT I in conjunction with aggregate boolean
clauses such as THEREIS (= I 1);
to WITH A = 1 WITH A = (1+ A);
** IT is only a special loop symbol within the first clause of a
conditional loop clause;
+ ** LOOP with a typed iteration variable over a hashtable now
+ signals a type error iff it should.
+ * fixed some other bugs revealed by Paul Dietz' test suite:
** FILE-STREAM now names the class previously known as FD-STREAM;
** in DEFSTRUCT, a bare :CONC-NAME (or a :CONC-NAME with no
argument) no longer signals an error;
of the slot symbol, rather than using the current package
((:CONC-NAME "") continues to intern the slot's name in the
current package);
- ** LOOP with a typed iteration variable over a hashtable now
- signals a type error iff it should;
* incremented fasl file version number, because of the incompatible
change to the DEFSTRUCT-DESCRIPTION structure, and again because
of the new implementation of DEFINE-COMPILER-MACRO.
- * fixed bug 223: functional binding is considered to be constant
- only for symbols in the CL package.
- * fixed bug 231: SETQ did not check the type of a variable being set

+changes in sbcl-0.7.12 relative to sbcl-0.7.11:
+ * minor incompatible change: code processed by the "interpreter" or
+ EVAL now has a compilation optimization policy of (DEBUG 2)
+ (changed from (DEBUG 1)) to improve debuggability of interactive
+ development, and to allow the use of the debug RETURN command in
+ such code.
+ * an experimental implementation of the RETURN command for the
+ debugger has been included. (thanks to Frederik Kuivinen)
+ * fixed bug 62: constraints were not propagated into a loop.
+ * fixed bug in embedded calls of SORT (reported and investigated by
+ Wolfgang Jenkner).
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** printing and reading of arrays with some dimensions having
+ length 0 (thanks to Gerd Moellmann);
+ ** BOA constructor with &AUX argument without a default value does
+ not cause a type error;
+ ** CONSTANTP now returns true for all self-evaluating objects.
+
+changes in sbcl-0.7.13 relative to sbcl-0.7.12:
+ * incompatible packaging change: in line with Unix convention,
+ SBCL now looks for its core file in /usr/{local/,}lib/sbcl/sbcl.core
+ if it's not in $SBCL_HOME. It also sets SBCL_HOME to match.
+ * REQUIRE and PROVIDE are now optionally capable of doing something
+ useful. See the documentation string for REQUIRE.
+ * infrastructure for a managed SBCL contrib system: contributed
+ modules in this release include:
+ ** the ASDF system definition facility;
+ ** an interface to the BSD Sockets API;
+ ** an ACL-like convenience interface to the repl;
+ (thanks to Kevin Rosenberg)
+ ** an implementation of ROTATE-BYTE, with efficient implementation
+ on x86 hardware;
+ * fixed a bug in LOG, so that LOG of a rational argument near 1 now
+ gives a closer approximation to the right answer than previously.
+ (thanks to Raymond Toy)
+ * fixed bug 157: TYPEP, SUBTYPEP, UPGRADED-ARRAY-ELEMENT-TYPE and
+ UPGRADED-COMPLEX-PART-TYPE now take (ignored, in all situations)
+ optional environment arguments, as required by ANSI.
+ * fixed bugs in other functions taking environment objects, allowing
+ calls with an explicit NIL environment argument to be compiled
+ without error.
+ * fixed bug 228: primary return values from
+ FUNCTION-LAMBDA-EXPRESSION are either NIL or suitable for input to
+ COMPILE or FUNCTION.
+ * fixed a bug in DEFSTRUCT: predicates for :NAMED structures with
+ :TYPE will no longer signal errors on innocuous objects.
+ * fixed bug 231b: SETQ is better at respecting type declarations in
+ the lexical environment.
+ * fixed a bug in DEFCLASS: classes named by symbols with no or
+ unprintable packages can now be defined.
+ * fixed a bug in RESTART-BIND: The :TEST-FUNCTION option had been
+ carelessly renamed to :TEST-FUN. (thanks to Robert E. Brown)
+ * fixed compiler failure related to checking types of functions.
(reported by Robert E. Brown)
+ * the compiler is now much more consistent in its error-checking
+ treatment of bounding index arguments to sequence functions: in
+ (SAFETY 3) code, errors will be signalled in almost all cases if
+ invalid sequence bounding indices are passed to functions defined
+ by ANSI to operate on sequences.
+ * fixed a bug in the build procedure: documentation of SBCL-specific
+ packages is now preserved and available in the final Lisp image.
+ * lifted FDEFINITION lookup out of loops in the implementation of
+ many list operations. (thanks to Robert E. Brown)
+ * fixed a bug in the reader: the #n# reader macro now works for
+ objects of type STANDARD-OBJECT. (reported by Tony Martinez)
+ * the compiler is now aware that SYMBOL-FUNCTION returns a FUNCTION
+ and that READ-DELIMITED-LIST returns a LIST. (thanks to Robert
+ E. Brown and Tony Martinez respectively)
+ * PCL is now smarter about SLOT-VALUE, (SETF SLOT-VALUE) and
+ SLOT-BOUNDP: in particular, it is now able to optimize them much
+ better, and is now not vulnerable to having packages renamed.
+ Furthermore, a compliance bug has been fixed: SLOT-MISSING is now
+ always called when a slot is not present in an instance. (thanks
+ to Gerd Moellmann)
+ * fixed a bug related to CONCATENATED-STREAMs: PEEK-CHAR will no
+ longer signal an error on unreading a character following EOF on
+ the previous constituent stream. (thanks to Tony Martinez)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** ARRAY-IN-BOUNDS-P now allows arbitrary integers as arguments,
+ not just nonnegative fixnums;
+ ** the logical bit-array operators such as BIT-AND now accept an
+ explicit NIL for their "opt-arg" argument (to indicate a
+ freshly-consed result bit-array);
+ ** ELT now signals an error on an invalid sequence index in safe
+ code;
+ ** the type system is now cleverer about negations of numeric
+ types, and consequently understands the BIGNUM and RATIO types
+ better;
+ ** the type system is now cleverer about the interaction between
+ INTEGER and RATIO types: while bugs still remain, many more
+ cases are accurately computed;
+ ** in TYPECASE, OTHERWISE now only introduces an otherwise-clause
+ if it is in the last clause;
+ ** CONSTANTLY now correctly returns a side-effect-free function in
+ all cases;
+ ** DECLARE is no longer treated as a special-operator; in
+ particular, SPECIAL-OPERATOR-P no longer returns T for DECLARE;
+ * incremented fasl file version number due to the change in the
+ DEFSTRUCT-SLOT-DESCRIPTION structure.
+
+changes in sbcl-0.7.14 relative to sbcl-0.7.13:
+ * a better implementation of SXHASH on (simple) bit vectors,
+ measured both in execution speed and in distribution of results
+ over the positive fixnums, has been installed. Likewise, a better
+ implementation of EQUAL for simple bit vectors is now available.
+ * fixed CEILING optimization for a divisor of form 2^k.
+ * fixed bug 240 (emitting extra style warnings "using the lexical
+ binding of the symbol *XXX*" for &OPTIONAL arguments). (reported
+ by Antonio Martinez)
+ * fixed SXHASH, giving different results for NIL depending on type
+ declarations (SYMBOL or LIST). (thanks to Gerd Moellmann)
+ * fixed bug in DEFPARAMETER and DEFVAR: they could assign a lexical
+ variable. (found by Rolf Wester)
+ * SBCL does not ignore type declarations for special
+ variables. (reported by rif on c.l.l 2003-03-05)
+ * some bug fixes in contrib/sb-aclrepl/
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** a bug in the CONS type specifier, whereby the CAR and CDR
+ types got intertwined, has been fixed;
+ ** the type system is now able to reason about the interaction
+ between INTEGER and RATIO types more completely;
+ ** APPEND, [N]REVERSE and NRECONC check that those their
+ arguments, which must be proper lists, are really so;
+ ** An array specialized to be unable to hold elements has been
+ implemented, as required -- yes, really -- by ANSI;
+ ** GETF and GET-PROPERTIES throw a TYPE-ERROR, not a SIMPLE-ERROR,
+ on malformed property lists;
+
+changes in sbcl-0.8.0 relative to sbcl-0.7.14
+ * The old distinction between CL:CLASS objects and SB-PCL:CLASS
+ objects has been eliminated. 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. (thanks to Gerd Moellmann)
+ * fixed evaluation order in optional entries. (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. (reported by
+ Brian Downing on c.l.l)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** COPY-ALIST now signals an error if its argument is a dotted
+ list;
+ ** condition slots are now accessed more correctly in the presence
+ of multiple initargs for a given slot;
+ ** the USE-VALUE, CONTINUE and STORE-VALUE functions now correctly
+ exclude restarts of the same name associated with a different
+ condition;
+ ** DEFCLASS of forward-referenced classes with another
+ forward-referenced class in the superclasses list no longer
+ causes an error;
+ ** condition slots are now initialized once each, not multiple
+ times; (thanks to Gerd Moellmann)
+ ** CONVERT-MORE-CALL failed on a lambda list (&KEY); (thanks to
+ Gerd Moellmann)
+ ** &WHOLE and &REST arguments in macro lambda lists are patterns;
+ ** NSET-EXCLUSIVE-OR does not return extra elements when its
+ arguments contain duplicated elements;
+ ** RESTART-CASE understands local macros;
+ ** ... and associates exactly its own restarts with a condition;
+ ** ENDP in safe mode checks its argument to be of type LIST;
+ ** COPY-SYMBOL in a threaded build no longer fails when the symbol
+ in question is unbound;
+ ** optimized MAKE-INSTANCE functions no longer cause internal
+ assertion failures in the presence of duplicate initargs;
