 changes relative to sbcl-1.0.34:
+  * optimization: Slightly better code is generated for integer<->float
+    conversions and for single-float<->double-float conversions on x86-64.
   * optimization: SB-ROTATE-BYTE:ROTATE-BYTE now generates more efficient
     code for 32-bit and 64-bit rotations on x86-64.
+  * bug fix: TRUNCATE with a single single-float or double-float argument is
+    properly inlined when possible.  (launchpad bug lp#489388)
   * bug fix: Passing a rotation count of zero to SB-ROTATE-BYTE:ROTATE-BYTE
     no longer causes a compiler error on x86 and ppc.
   * bug fix: GET-MACRO-CHARACTER bogusly computed its second return value
