+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)
+  * 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)
+  * bug fix: non-local exit from a WITH-ALIEN form no longer causes
+    alien-stack leakage. (reported by Andy Hefner)
+  * bug fix: PROGV signals an error when an attempt to violate declared
+    type of a variable or bind a constant is made.
+  * bug fix: SET signals an error when an attempt to violate declared
+    type of a variable is made.
+  * bug fix: restart computation during the execution of a restart
+    test function no longer causes infinite recursion. (reported by
+    Michael Weber)
+  * bug fix: calling SB-COVER:REPORT with a non-directory pathname now
+    signals an error. (thanks to Pierre Mai)
+  * bug fix: EXPORT left symbol unexported in conflict situations.
+    (thanks to Michael Weber)
+  * bug fix: correctly handle name conflicts involving CL:NIL.
+    (thanks to Michael Weber)
+  * bug fix: RESOLVE-CONFLICT restart for name conflicts handles
+    conflicts arising from USEing package with conflicting symbols
+    correctly. (thanks to Michael Weber)

 changes in sbcl-1.0.19 relative to 1.0.18:
+  * new feature: user-customizable variable SB-EXT:*MUFFLED-WARNINGS*;
+    warnings that go otherwise unhandled will be muffled if they are
+    of the type that's the value of this variable.  
   * optimization: stack allocation is slightly more efficient on x86
     and x86-64.
   * bug fix: DEFSTRUCT forms with user-specified :CONSTRUCTOR options,
@@ -10,6 +65,9 @@ changes in sbcl-1.0.19 relative to 1.0.18:
     presense of non-foldable SATISFIES types.
   * bug fix: stack analysis missed cleanups of dynamic-extent
     arguments in non-let-converted calls to local functions.
+  * improvements to the Windows port:
+    ** adjusted address spaces for building on both Win32 and
+       Win64. (thanks for John Connors)
   * fixed some bugs revealed by Paul Dietz' test suite:
     ** interval arithmetic during type derivation used inexact integer
        to single-float coercions.
