@@ -4,11 +4,21 @@ changes in sbcl-1.0.20 relative to 1.0.19:
     SB-C::STACK-ALLOCATE-DYNAMIC-EXTENT, SB-C::STACK-ALLOCATE-VECTOR,
     and SB-C::STACK-ALLOCATE-VALUE-CELLS no longer exist. See documentation
     and SB-EXT:*STACK-ALLOCATE-DYNAMIC-EXTENT* for details.
+  * documentation: some slot access efficiency guidelines have been
+    added to the user manual.
   * optimization: ASSOC-IF, ASSOC-IF-NOT, MEMBER-IF, MEMBER-IF-NOT,
     RASSOC, RASSOC-IF, and RASSOC-IF-NOT are now equally efficient
     as ASSOC and MEMEBER.
+  * optimization: calls to ASSOC, MEMBER, and RASSOC can be transformed
+    to more efficient EQ-comparison versions more often.
+  * optimization: enhanced derivation of DOLIST iteration variable type
+    for constant lists.
+  * optimization: constant folding of simple (LIST ...) forms as DOLIST
+    arguments.
   * optimization: runtime lookup of function definitions can be
     elided in more cases, eg: (let ((x 'foo)) (funcall foo)).
+  * optimization: compiler is able to derive the return type of
+    (AREF (THE STRING X) Y) as being CHARACTER.
   * bug fix: fixed #427: unused local aliens no longer cause compiler
     breakage. (reported by Stelian Ionescu, Andy Hefner and Stanislaw
     Halik)
