+changes in sbcl-0.8.20 (0.9alpha.0?) relative to sbcl-0.8.19:
   * fixed disassembly of SHLD and SHRD on x86.  (thanks to David
     Lichteblau)
   * 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

     ** 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

+  * 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 disassembler understands more x86-64. (thanks to Cheuksan Wang)
+    ** The regression tests use SB-ALIEN:INT instead of SB-ALIEN:INTEGER

+  * fixed some bugs revealed by Paul Dietz' test suite:

+    ** SET-SYNTAX-FROM-CHAR correctly copies multiple-escape character

+       normal termination.
+    ** Pretty-printing backquoted forms when *PRINT-CIRCLE* is true
+       works more reliably.
