+changes in sbcl-1.0.9 relative to sbcl-1.0.8:
+  * bug fix: new compiler transforms for MEMBER and ASSOC were affected
+    by printer control variables. (reported by Dan Corkill)
+
 changes in sbcl-1.0.8 relative to sbcl-1.0.7:
-  * enhancement: closed over variables can be stack-allocated on x86 and
-    x86-64.
+  * enhancement: experimental macro SB-EXT:COMPARE-AND-SWAP provides
+    atomic compare-and-swap operations on threaded platforms.
+  * enhancement: experimental function SB-EXT:RESTRICT-COMPILER-POLICY
+    allows assining a global minimum value to optimization qualities
+    (overriding proclamations and declarations).
+  * enhancement: closed over variables can be stack-allocated on x86
+    and x86-64.
+  * performance bug fix: GETHASH and (SETF GETHASH) are once again
+    non-consing.
+  * optimization: slot definition lookup is now O(1). This speeds up
+    eg. SLOT-VALUE and (SETF SLOT-VALUE) with variable slot names.
+  * optimization: STRING-TO-OCTETS is now up to 60% faster for UTF-8.
+  * optimization: ASSOC and MEMBER can now be open-coded for all
+    combinations of keyword arguments when second argument is constant
+    and SPEED >= SPACE. In other cases a specialized version is
+    selected.
+  * bug fix: using obsoleted structure instances with TYPEP and
+    generic functions now signals a sensible error.
+  * bug fix: threads waiting on GET-FOREGROUND can be interrupted.
+    (reported by Kristoffer Kvello)
+  * bug fix: backtrace construction is now more careful when making
+    lisp-objects from pointers on the stack, to avoid creating bogus
+    objects that can be seen by the GC.
+  * bug fix: defaulting of values in contexts expecting more than 7
+    variables now works on x86-64.  (reported by Christopher Laux)
+  * bug fix: modifications to packages (INTERN, EXPORT, etc) are now
+    thread safe.
+  * bug fix: (SETF SYMBOL-PLIST) no longer allows assigning a non-list
+    as the property-list of a symbol.
+  * bug fix: DEFMETHOD forms with CALL-NEXT-METHOD in the method body,
+    in EVAL-WHEN forms with both :COMPILE-TOPLEVEL and :LOAD-TOPLEVEL 
+    situations requested, are once again file-compileable.  (reported
+    by Sascha Wilde)
 
 changes in sbcl-1.0.7 relative to sbcl-1.0.6:
   * MOP improvement: support for user-defined subclasses of
