+  * new feature: SB-EXT:ATOMIC-INCF allows atomic incrementation of
+    appropriately typed structure slots without locking.
+  * enhancement: reduced conservativism on GENCGC platforms: on
+    average 45% less pages pinned (measured from SBCL self build).
+  * bug fix: SB-EXT:COMPARE-AND-SWAP on SYMBOL-VALUE can no longer
+    mutate constant symbols or violate declaimed type of the symbol.

 changes in sbcl-1.0.20 relative to 1.0.19:
   * minor incompatible change: OPTIMIZE qualities
     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.
+  * optimization: CLRHASH on empty hash-tables no longer does pointless
+    work. (thanks to Alec Berryman)
+  * optimization: REPLACE deftransforms don't punt when :START1 or
+    :START2 is given
+  * bug fix: compiling DESTRUCTURING-BIND on constant list arguments
+    no longer emits a code deletion note. (reported by Andrew
+    Gasparovic)
+  * bug fix: bogus odd-number-of-keywords STYLE-WARNINGs from calls to
+    functions with an odd number of &OPTIONAL arguments, a &REST
+    argument, and one or more &KEY arguments at the call site.
+  * bug fix: STYLE-WARNINGs for functions with both &OPTIONAL and &KEY
+    arguments appeared at call sites as well.
+  * bug fix: fixed #425; CLOSE drops input buffers from streams, so
+    READ-LINE &co can no longer read from them afterwards. (reported
+    by Damien Cassou)
   * bug fix: fixed #427: unused local aliens no longer cause compiler
     breakage. (reported by Stelian Ionescu, Andy Hefner and Stanislaw
     Halik)
