 changes in sbcl-0.8.4 relative to sbcl-0.8.3:
   * fixed compiler performance when processing loops with a step >1;
+  * bug fix: DOCUMENTATION now retrieves generic function
+    documentation.  Also, DOCUMENTATION and (SETF DOCUMENTATION)
+    support has been systematized, and now supports the methods
+    specified by ANSI, along with a default method and a method for
+    slot documentation.  (reported by Nathan Froyd)
+  * bug fix: effective methods associated with a generic function are
+    no longer cached over a change of that generic function's method
+    combination.  (reported by Andreas Fuchs)
+  * optimization: restored some effective method precomputation in
+    CLOS (turned off by an ANSI fix in sbcl-0.8.3); the amount of
+    precomputation is now tunable.
+  * optimization: compiler-internal data structure use has been
+    reviewed, and changes have been made that should improve the
+    performance of the compiler by about 20%.
+  * bug fix: in some situations compiler did not report usage of
+    generic arithmetic in (SPEED 3) policy.
 
 planned incompatible changes in 0.8.x:
   * (not done yet, but planned:) When the profiling interface settles
