+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.
+  * optimization: runtime lookup of function definitions can be
+    elided in more cases, eg: (let ((x 'foo)) (funcall foo)).
+  * 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)
