     inlining cases: failure to stack allocate when equivalent code is manually
     open coded is now considered a bug.
   * improvement: the Unicode character database has been upgraded to the
-    Unicode 5.0.1 standard, giving names and properties to a number of new
+    Unicode 5.1 standard, giving names and properties to a number of new
     characters, and providing a few extra characters with case
     transformations.
+  * improvement: the system now recognizes and produces names for Unicode
+    Hangul syllable characters.
   * new feature: experimental :EMIT-CFASL parameter to COMPILE-FILE can
     be used to output toplevel compile-time effects into a separate .CFASL
     file.
   * optimization: COERCE to VECTOR, STRING, SIMPLE-STRING and recognizable
     one-dimenstional subtypes of ARRAY is upto 70% faster when the coercion is
     actually needed.
+  * optimization: TRUNCATE on known single- and double-floats is upto 25%
+    faster.
   * optimization: division of floating point numbers by constants uses
     multiplication by reciprocal when an exact reciprocal exists.
   * optimization: multiplication of single- and double-floats floats by
     constant two has been optimized.
   * optimization: ARRAY-IN-BOUNDS-P is resolved at compile-time when
     sufficient type information is available. (thanks to Leslie Polzer)
+  * optimization: SLOT-VALUE and (SETF SLOT-VALUE) with constant slot names on
+    known structure objects are as efficient as defstruct generated accessors.
   * optimization: unused vector creation can now be optimized away.
   * improvement: ASDF systems can now depends on SB-INTROSPECT.
   * improvement: a STYLE-WARNING is signalled when a generic function
