   * 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.
+  * optimization: the optimization of 32-bit logical and arithmetic
+    functions introduced in version 0.8.3 on the x86 has been
+    implemented on the mips, ppc and sparc platforms.
   * 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
