 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 #308: non-graphic characters now all have names, as
+    required.  (reported by Bruno Haible)
+  * 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
+    strings which can potentially compare true despite having distinct
+    specialized array element types.
+  * FORMAT compile-time argument count checking has been enhanced.
+    (report from Bruno Haible for CMUCL)
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** RENAME-PACKAGE allows all package designators as new package
+       names.
+    ** constraint propagation and lambda variable substitution are
+       more cautious in dealing with partially deleted code.
+    ** compiler sometimes lost reoptimization passes.
