 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 checks its arguments for being proper lists;
+    ** 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;
+       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 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 some bugs revealed by Paul Dietz' test suite:
+    ** COPY-ALIST now signals an error if its argument is a dotted
+       list;
+
 planned incompatible changes in 0.7.x:
   * (not done yet, but planned:) When the profiling interface settles
     down, maybe in 0.7.x, maybe later, it might impact TRACE. They both
