@@ -2013,22 +2013,48 @@ changes in sbcl-0.8.4 relative to sbcl-0.8.3:
     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)
+  * fixed bug 285: TRUNCATE on bignum arguments, and indeed bignum
+    arithmetic in general, is now much more reliable on the PPC
+    platform.
   * 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.
+  * bug 145b fix: compiler used wrong type specifier while converting
+    MEMBER-types to numeric.
   * 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.
+    ** PARSE-INTEGER returned the index of a terminator instead of the
+       upper bounding index of a substring in case :JUNK-ALLOWED NIL.
+    ** PARSE-INTEGER returned an incorrect index being applied to a
+       displaced string.
+    ** LCM with two arguments of 0 returns 0 rather than signalling
+       DIVISION-BY-ZERO.
+    ** unsigned addition of a 32-bit constant with the high bit set no
+       longer causes an internal compiler error on the x86.
+    ** LOGBITP accepts a non-negative bignum as its INDEX argument.
+    ** compiler incorrectly derived types of DPB and DEPOSIT-FIELD
+       with negative last argument.
 
 planned incompatible changes in 0.8.x:
