   * new feature: SB-INTROSPECT:ALLOCATION-INFORMATION provides information
     about object allocation.
+  * optimization: more efficient complex float and real float operations
+    on x86-64.
+  * optimization: division of a real float by a complex float is implemented
+    with a specialised code sequence.
+  * optimization: MAKE-INSTANCE with non-constant class-argument but constant
+    keywords is an order of magnitude faster.
+  * optimization: MAKE-INSTANCE with constant keyword arguments is x2-4 faster
+    in the presence of :AROUND or non-standard primary INITIALIZE-INSTANCE
+    methods, and similarly for non-standard metaclass classes as long as there
+    are no methods additional on MAKE-INSTANCE.
   * optimization: more efficient type-checks for FIXNUMs when the value
     is known to be a signed word on x86 and x86-64.
-  * optimization: (EXPT -1 INTEGER) is compiled into (IF (EVENP INTEGER) 1 -1).
-    (thanks to Stas Boukarev)
+  * optimization: compiler now optimizes (EXPT -1 INTEGER), (EXPT -1.0 INTEGER),
+    and (EXPT -1.0d0 INTEGER) into an ODDP test. (thanks to Stas Boukarev and
+    Paul Khuong)
+  * improvement: less unsafe constant folding in floating point arithmetic,
+    especially for mixed complex/real -float operations.
+  * improvement: complex float division is slightly more stable.
+  * improvement: DESCRIBE output has been reworked to be easier to read and
+    contains more pertinent information.
   * improvement: failure to provide requested stack allocation compiler notes
     provided in all cases (requested stack allocation not happening without a
     note being issued is now considered a bug.)
   * optimization: compiler is smarter about delegating argument type checks to
     callees.
+  * bug fix: SB-POSIX exports the documented types and functions
+    FILE-DESCRIPTOR and FILENAME, and also the corresponding -DESCRIPTOR
+    types. (reported by "abhi")
   * bug fix: on 64 bit platforms FILL worked incorrectly on arrays with
     upgraded element type (COMPLEX SINGLE-FLOAT), regression from 1.0.28.55.

   * bug fix: GENTEMP is now unaffected by pretty printer dispatch table.
