+ ** 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 removed. 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.
+ * 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 some bugs revealed by Paul Dietz' test suite:
+ ** COPY-ALIST now signals an error if its argument is a dotted
+ list;
