+changes in sbcl-0.8.19 relative to sbcl-0.8.18:
+  * enhancement: saving cores with foreign code loaded is now
+    supported on ppc/Darwin in addition to the previously supported
+    platforms.
+
+changes in sbcl-0.8.18 relative to sbcl-0.8.17:
+  * new feature: reloading changed shared object files with
+    LOAD-SHARED-OBJECT now causes the new definitions to take effect.
+  * new feature: references to foreign variables and functions
+    can now be compiled and loaded before the corresponding shared 
+    object file is loaded, as long as the foreign definitions are
+    available at runtime.
+  * Solaris 10 (aka SunOS 5.10) on the SPARC platform is now
+    supported.  (thanks to Dan Debertin)
+  * SB-ALIEN enums can now be represented in Lisp by any symbols, not
+    just keywords.  (thanks to Vincent Arkesteijn)
+  * fixed bug #331: structure-class instances corresponding to
+    DEFSTRUCT forms are now created eagerly.
+  * fixed bug #345: backtraces from calls to undefined functions work
+    on x86 as well. Related bug #61 is now also partially fixed on x86
+    (backtraces from throws to unknown catch tags.)
+  * bug fix: lambda-list parsing is now stricter vrt. order and number
+    of lambda-list keywords.
+  * bug fix: as specified by AMOP, an error is signalled if a
+    class-option appears multiple times in a DEFCLASS form. (reported
+    by Bruno Haible)
+  * bug fix: RANDOM can be compiled when the compiler derives the type
+    of its numeric argument as a disjoint set of small integers.
+    (reported by Paul Dietz)
+  * bug fix: starting a core saved with shared objects loaded when
+    those objects are not available no longer causes threaded SBCL to 
+    hang. (reported by Sean Ross)
+  * bug fix: evaluated FUNCTION no longer bypasses encapsulation (eg.
+    TRACE).
+  * bug fix: (SETF MACRO-FUNCTION) now accepts an optional environment
+    argument, which must always be NIL. (reported by Kalle Niemitalo)
+  * bug fix: printing 1.0d+23 no longer results in an error.
+    (reported by Rolf Wester for CMUCL; bug fix from Raymond Toy)
+  * bug fix: structure slot setters preserve evaluation order. (thanks
+    to Gabor Melis)
+  * fixed some bugs related to Unicode integration:
+    ** RUN-PROGRAM can allow its child to take input from a Lisp
+       stream.  (reported by Stefan Scholl)
+    ** ASDF-INSTALL successfully downloads .tar.gz files in all
+       locales.  (reported by Ken Causey)
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** INCF, DECF and REMF evaluate their place form as specified in
+       CLtS 5.1.3.
+    ** FORMATTER expands ~{ ~} iteration directives with V or #
+       parameters correctly.
+    ** FORMATTER deals with the ~@[ ~] conditional directive where the
+       consequent uses no arguments correctly.
+    ** the system has a partial understanding of the (COMPLEX RATIO)
+       type specifier.
+    ** UPGRADED-COMPLEX-PART-TYPE obeys the lattice upgrading rules
+       required.

 changes in sbcl-0.8.17 relative to sbcl-0.8.16:
+  * new feature: a build-time option (controlled by the :SB-UNICODE
+    keyword feature, enabled by default) for building the system with
+    support for the entire 21-bit character space defined by the
+    Unicode consortium.
+  * new feature: the system now has rudimentary external-format
+    support; the primary user-visible change at this time is that
+    characters with the high bit set (such as lower-case-e-acute) will
+    print correctly to a terminal in a UTF-8 environment.
   * minor incompatible change: BASE-CHAR no longer names a class;
     however, CHARACTER continues to do so, as required by ANSI.
+  * minor incompatible change: SB-DEBUG:*DEBUG-PRINT-FOO* variables
+    are no longer supported, and SB-DEBUG:*DEBUG-PRINT-VARIABLE-ALIST*
+    has been moved to the SB-EXT package (temporarily re-exported from
+    SB-DEBUG).
+  * minor incompatible change: SB-C::*COMPILER-ERROR-PRINT-FOO* variables
+    are no longer supported: use SB-EXT:*COMPILER-PRINT-VARIABLE-ALIST*
+    instead. 
+  * fixed bug #351: better error-handlind and reporting for malformed
+    LET and LET* forms.
+  * fixed bug #350: bignum-printing is now more memory-efficient,
+    allowing printing of very large bignums, eg. (expt 2 10000000).
+    (reported by Bruno Haible)
+  * fixed bug #302: better primitive-type selection for intersection
+    types.
+  * fixed bug #308: non-graphic characters now all have names, as
+    required.  (reported by Bruno Haible)
+  * bug fix: redefining a class with different superclasses now correctly
+    removes it from the direct-subclasses of its previous superclasses.
+    (reported by David Morse)
+  * bug fix: (SETF FIND-CLASS) using a FORWARD-REFERENCED-CLASS as the
+    new value now works. (reported by Bruno Haible)
+  * bug fix: correct canonicalization of multiple non-standard slot
+    options in DEFCLASS as per AMOP 5.4.2. (reported by Bruno Haible)
+  * bug fix: SB-MOP:CLASS-PROTOTYPE now signals an error if the class
+    is not yet finalized, as required by AMOP. (reported by Bruno Haible)
+  * bug fix: SB-MOP:ALLOCATE-INSTANCE method for instances of BUILT-IN-CLASS
+    now exists, an signals an error.
+  * bug fix: duplicate LOOP variable bindings now signal PROGRAM-ERROR
+    during macroexpansion for non-iteration variables as well. (reported 
+    by Bruno Haible for CMUCL)
+  * bug fix: Cyclic structures and unprintable objects in compiler
+    messages no longer cause errors. (reported by Bruno Haible)
   * bug fix: READ, READ-PRESERVING-WHITESPACE, READ-DELIMITED-LIST,
     and READ-FROM-STRING all now return a primary value of NIL if
     *READ-SUPPRESS* is true.  (reported by Bruno Haible for CMUCL)

     name conflict situations in CLHS 11.1.1.2.5, and provide a restart
     permitting resolution in favour of any of the conflicting symbols.
     (reported by Bruno Haible for CMUCL)
+  * bug fix: EQUAL compiler optimizations is less aggressive on

+       point ranges without signalling FLOATING-POINT-OVERFLOW.
+    ** Functions with IR1-transformations can create intercomponent
+       references to global functions.
+    ** NIL parameter to the FORMAT directive ~^ means `unsupplied
+       parameter'.
+    ** FORMAT ~R treats a nil value for its first parameter correctly.
