   * optimization: the compiler now derives simple types for LOAD-VALUE-FORMs.
   * improvement: less unsafe constant folding in floating point arithmetic,
     especially for mixed complex/real -float operations.
+  * optimization: constant double and single floats are stored in native
+    unboxed format on x86[-64].
+  * optimization: smarter code for arithmetic operations with constant floats,

   * improvement: complex float division is slightly more stable.
   * improvement: DESCRIBE output has been reworked to be easier to read and
     contains more pertinent information.
