+  * improvement: stack allocation is should now be possible in all nested
+    inlining cases: failure to stack allocate when equivalent code is manually
+    open coded is now considered a bug.
+  * new feature: experimental :EMIT-CFASL parameter to COMPILE-FILE can
+    be used to output toplevel compile-time effects into a separate .CFASL
+    file.
+  * optimization: multiplication and division of single- and double-floats
+    with constant +/-one has been optimized.
+  * optimization: multiplication of single- and double-floats floats by
+    constant two has been optimized.
+  * bug fix: moderately complex combinations of inline expansions could
+    be miscompiled if the result was declared to be dynamic extent.
+  * bug fix: in some cases no compiler note about failure to stack allocate
+    was emitted, even if the objects were in fact heap allocated.
+  * bug fix: minor violation of "otherwise inaccessible" rule for stack
+    allocation could cause objects users might reasonably expect to
+    be heap allocated to be stack allocated.
+  * bug fix: DESCRIBE signalled an error for generic functions under
+    certain circumstances. (reported by Leslie Polzer)

   * minor incompatible change: SB-THREAD:JOIN-THREAD-ERROR-THREAD and
     SB-THREAD:INTERRUPT-THREAD-ERROR-THREAD have been deprecated in favor
     of SB-THREAD:THREAD-ERROR-THREAD.

   * new feature: SB-INTROSPECT:ALLOCATION-INFORMATION provides information
     about object allocation.
+  * 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 somewhat
-    faster for non-standard metaclass classes as long as there are no methods
-    additional on MAKE-INSTANCE and initialization arguments can be validated
-    at compile-time.
+  * 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: 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)
+  * optimization: compiler is smarter about delegating argument type checks to
+    callees.
+  * optimization: several character functions are now compiled somewhat more
+    efficiently. (reported by Lynn Quam)
+  * 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,
+    complex floats, or integers on x86[-64].
+  * optimization: smarter code for conjugate/multiplication of float complexes
+    and abs/negate of floats on x86-64.
+  * optimization: more efficient complex float and real float operations on
+    x86-64.
+  * 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.
