+changes in sbcl-1.0.8 relative to sbcl-1.0.7:
+  * 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: STRING-TO-OCTETS is now up to 60% faster for UTF-8.
+  * 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.
