   * minor incompatible change: SB-C::*COMPILER-ERROR-PRINT-FOO* variables
     are no longer supported: use SB-EXT:*COMPILER-PRINT-VARIABLE-ALIST*
     instead. 
+  * fixed bug #351: better error-handlind and reporting for malformed
+    LET and LET* forms.
+  * fixed bug #350: bignum-printing is now more memory-efficient,
+    allowing printing of very large bignums, eg. (expt 2 10000000).
+    (reported by Bruno Haible)
+  * fixed bug #302: better primitive-type selection for intersection
+    types.
   * fixed bug #308: non-graphic characters now all have names, as
     required.  (reported by Bruno Haible)
+  * bug fix: redefining a class with different superclasses now correctly
+    removes it from the direct-subclasses of its previous superclasses.
+    (reported by David Morse)
+  * bug fix: (SETF FIND-CLASS) using a FORWARD-REFERENCED-CLASS as the
+    new value now works. (reported by Bruno Haible)
+  * bug fix: correct canonicalization of multiple non-standard slot
+    options in DEFCLASS as per AMOP 5.4.2. (reported by Bruno Haible)
+  * bug fix: SB-MOP:CLASS-PROTOTYPE now signals an error if the class
+    is not yet finalized, as required by AMOP. (reported by Bruno Haible)
+  * bug fix: SB-MOP:ALLOCATE-INSTANCE method for instances of BUILT-IN-CLASS

+  * bug fix: duplicate LOOP variable bindings now signal PROGRAM-ERROR
+    during macroexpansion for non-iteration variables as well. (reported 
+    by Bruno Haible for CMUCL)
   * bug fix: Cyclic structures and unprintable objects in compiler
     messages no longer cause errors. (reported by Bruno Haible)
