@@ -2011,16 +2011,34 @@ changes in sbcl-0.8.4 relative to sbcl-0.8.3:
   * 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)
+  * bug fix: RUN-PROGRAM now does not fail if some element in $PATH
+    names a non-existent directory.  (thanks to Andreas Fuchs)
+  * bug fix: ROUND and TRUNCATE could, under certain circumstances on
+    the PPC platform, lead to stack corruption; this has been fixed.
+    (reported by Rainer Joswig)
+  * bug fix: ASH on an (UNSIGNED-BYTE 32) with a shift of -32 or lower
+    no longer ever returns 1 instead of 0.  (thanks to Lars Brinkhoff)
   * 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%.
+  * optimization: performance of FILL (and :INITIAL-ELEMENT) on
+    simple-base-strings and simple-bit-vectors is improved.
   * microoptimization: the compiler is better able to make use of the
     x86 LEA instruction for multiplication by constants.
   * bug fix: in some situations compiler did not report usage of
     generic arithmetic in (SPEED 3) policy.
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** the RETURN clause in LOOP is now equivalent to DO (RETURN ...).
+    ** ROUND and FROUND now give the right answer when given very
+       small float arguments.
+    ** (FLOAT X) for X of type DOUBLE-FLOAT now returns X in all
+       circumstances.
+    ** optimizer for (EXPT X 0) did not work for X not of type FLOAT.
+    ** (GCD 0 <negative-integer>) returned <negative-integer>.
+    ** LCM should return a non-negative integer.
 
 planned incompatible changes in 0.8.x:
   * (not done yet, but planned:) When the profiling interface settles
