+changes in sbcl-0.8.20 (0.9alpha.0?) relative to sbcl-0.8.19:
+  * fixed inspection of specialized arrays. (thanks to Simon Alexander)
+  * fixed disassembly of SHLD and SHRD on x86.  (thanks to David
+    Lichteblau)
+  * fixed loading of multiply forward-referenced layouts. 
+    (thanks to Cheuksan Wang)
+  * fixed bug 7: less verbose COMPILE-FILE output. Additionally, the
+    output is now directed to *STANDARD-OUTPUT* as specified by ANSI. 
+    (see COMPILE-FILE documentation for details of :PRINT option)
+  * fixed bugs 19 and 317: fixed-format floating point printing is
+    more accurate.  This also fixes a bug reported by Adam Warner
+    related to the ~@F format directive.
+  * fixed bug 371: bignum print/read inconsistency. (thanks to Harald
+    Hanche-Olsen)
+  * fixed bug: SET-SYNTAX-FROM-CHAR correctly shallow-copies a
+    dispatch table if the from-char is a dispatch macro character.
+  * fixed bug: COUNT and EQUAL on bit vectors with lengths divisible
+    by the wordsize no longer ignore the last word.  (reported by Lutz
+    Euler)
+  * fixed bug in type checking of dynamic-extent variables. (reported
+    by Svein Ove Aas)
+  * optimization: sequence traversal functions use their freedom to
+    coerce function designators to functions.
+  * optimization: code with many calls to CLOS methods specialized on
+    CLOS classes has had redundant type checks removed.
+  * optimization: added declarations to speed up operations that access
+    the internal character database (for example STRING-UPCASE)
+  * optimization: comparison operations between floats and sufficiently small
+    fixnums no longer create extra rationals
+  * fixed some bugs related to Unicode integration:
+    ** portions of multibyte characters at the end of buffers for
+       character-based file input are correctly transferred to the
+       start of the buffer at the next read.
+    ** COMPILE-FILE now respects any EXTERNAL-FORMAT argument given,
+       passing it through to OPEN.
+    ** LOAD on source files likewise passes any EXTERNAL-FORMAT
+       argument given to internal calls to OPEN.
+    ** the built-in comment readers (introduced by character sequences
+       ";" and "#|") are more forgiving to encoding errors; they will
+       STYLE-WARN and then attempt to resync the stream at a character
+       boundary.  (thanks to Teemu Kalvas)
+  * fixed some bugs in the x86-64 port:
+    ** Negative short int return values from c-calls are sign-extended
+       correctly.
+    ** The stack is aligned to 16-bytes for c-calls, as required by
+       the ABI. (thanks to Cheuksan Wang)
+    ** The disassembler understands more x86-64. (thanks to Cheuksan Wang)
+    ** The regression tests use SB-ALIEN:INT instead of SB-ALIEN:INTEGER
+       for enums. (thanks to Vincent Arkesteijn)
+    ** Multiple small optimizations and bugfixes for floating point
+       operations.
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** Space, Tab, Linefeed, Return and Page have the invalid
+       secondary constituent character trait.
+    ** SET-SYNTAX-FROM-CHAR correctly copies multiple-escape character
+       syntax.
+    ** WITH-INPUT-FROM-STRING should only update the index place on
+       normal termination.
+    ** Pretty-printing backquoted forms when *PRINT-CIRCLE* is true
+       works more reliably.
+    ** Bit-array operations (BIT-AND and similar) worked incorrectly
+       with one-dimensional arrays with fill pointers.
+    ** TYPE-OF failed on a complex with an integer realpart and a
+       RATIO imagpart.
+    ** compiler failure during type inference for the code of form
+       (IF (EQL X (THE ...)) ...) (MISC.535).

 changes in sbcl-0.8.19 relative to sbcl-0.8.18:
   * new port: SBCL now works in native 64-bit mode on x86-64/Linux
     platform. The port supports 61-bit fixnums, large memory spaces
