   * enhancement: default dynamic-space size can be configured at build-time
     without touching source, using the --dynamic-space-size argument to make.sh.
+  * enhancement: DESCRIBE recognizes symbols naming optimization policy
+    qualities, and mentions ALWAYS-BOUND declarations.
+  * enhancement: ATOMIC-INCF now supports AREF of (SIMPLE-ARRAY SB-EXT:WORD (*))
+    as a place.
+  * enhancement: ASDF has been updated to 2.009.
+  * optimization: constant-folding exploits numeric and character types, in
+    addition member types.
+  * optimization: numeric, character and member types that are inhabited by
+    exactly one value are tested with EQL.
+  * optimization: more conditional branches are eliminated during IR1.
+    Branches are simplified before performing if/if-conversion, and simple
+    equivalent branches (that only read the same constant or variable) are
+    merged.
   * bug fix: compiler failed to derive the result-type of MAKE-ARRAY as
     (AND VECTOR (NOT SIMPLE-ARRAY)) when appropriate. (lp#309130)
   * bug fix: (THE (VALUES ...)) in LOAD-TIME-VALUE caused a compiler-error.

   * bug fix: non-unicode builds no longer fail (broken since 1.0.36.15).
