     not a COMPILER-ERROR (followed by some other strange error on
     choosing the CONTINUE restart).
   * bug fix: make.sh and friends are now more consistent in the way that
-    they for GNU "make".
+    they look for GNU "make".
 
 changes in sbcl-0.8.1 relative to sbcl-0.8.0:
+  * minor incompatible change: some nonsensical specialized lambda
+    lists (used in DEFMETHOD) which were previously ignored now signal
+    errors.
+  * minor incompatible change: the system is now aware of the types of
+    variables in the COMMON-LISP package, and will signal errors for
+    most violations of these type constraints (where previously they
+    were silently accepted).
+  * minor incompatible change: COMPILE-FILE now uses the freedom
+    afforded (ANSI 3.2.2.3) to use derived function types for
+    functions defined in the same file. This also permits the system
+    to warn on static type mismatches and function
+    redefinition.  (Currently it does not work with high DEBUG level.)
+  * when issuing notes, the compiler now signals a condition of type
+    SB-EXT:COMPILER-NOTE, and provides an associated MUFFLE-WARNING
+    restart for use in user handlers.  It is expected that the
+    COMPILER-NOTE condition will eventually become a condition
+    supertype to a hierarchy of note types, which will then be
+    handleable in a similar fashion; other than
+    SB-INT:SIMPLE-COMPILER-NOTE, an implementation detail, no such
+    note subtypes yet exist.
   * changes in type checking closed the following bugs:
     ** type checking of unused values (192b, 194d, 203);
     ** template selection based on unsafe type assertions (192c, 236);
     ** type checking in branches (194bc).
   * VALUES declaration is disabled.
-  * a short form of VALUES type specifier has ANSI meaning.
+  * a short form of VALUES type specifier has ANSI meaning (it has
+    increased the number of situations when SBCL cannot perform type
+    checking).
+  * fixed bug in DEFSTRUCT: once again, naming structure slots with
+    keywords or constants is permissible.
+  * STREAM-READ-SEQUENCE and STREAM-WRITE-SEQUENCE now have methods
+    defined on the relevant FUNDAMENTAL-BINARY-{INPUT,OUTPUT}-STREAM
+    classes.  (thanks to Antonio Martinez)
+  * improved ANSIness in DESCRIBE: The DESCRIBE function no longer
+    outputs FRESH-LINE or TERPRI, and no longer converts its stream
+    argument to a pretty-print stream. Instead, it leaves any such 
+    operations to DESCRIBE-OBJECT methods.
+  * bug fix: APROPOS now respects the EXTERNAL-ONLY flag.  (reported
+    by Teemu Kalvas)
+  * bug fix: NIL is now a valid destructuring argument in DEFMACRO
+    lambda lists.  (thanks to David Lichteblau)
+  * bug fix: defining a generic function with a :METHOD-CLASS being a
+    subclass of STANDARD-METHOD no longer causes stack exhaustion.
+    (thanks to Gerd Moellmann)
+  * fixed bug 246: increased compilation speed of long
+    MULTIPLE-VALUE-BIND (and likewise of NTH-VALUE with a constant
+    integer argument).
+  * a contributed module implementing COMPILER-LET and MACROEXPAND-ALL
+    has been included.
+  * DEFCONSTANT now throws a condition of type
+    SB-EXT:DEFCONSTANT-UNEQL if it is being asked to redefine a
+    constant to a non-EQL value; CONTINUE and ABORT restarts
+    respectively change and preserve the value.
+  * fixed bug 63: the code walker, part of the implementation of CLOS,
+    is better at handling symbol macros.
+  * bug fix: there is no longer a type named LENGTH.  (reported by
+    Raymond Toy)
+  * bug fix: in macro-like defining macros/special operators the
+    implicit block does not enclose lambda list.
+  * fixed bugs 10 and 43: VALUES, AND, OR and MEMBER are not suitable as 
+    atomic type specifiers, and their use properly signals an error now.
+  * bug fix: an argument count mismatch for a type specifier in code
+    being compiled no longer causes an unhandled error at compile
+    time, but signals a compile-time warning.
+  * fixed simple vector readable printing.
+  * bug fix: DESCRIBE takes more care over whether the class
+    precedence list slot of a class is bound before accessing it.
+    (reported by Markus Krummenacker)
+  * bug fix: FORMATTER can successfully compile pretty-printer format
+    strings which use variants of the ~* directive inside.
+  * bug fix: SEARCH now applies its TEST predicate to the elements of
+    the arguments in the correct order.  (thanks to Wolfhard Buss)
+  * fixed bug 235b: compiler uses return types of MAPCAR and friends
+    in type inference.  (thanks to Robert E. Brown)
+  * bug fix: reading in symbols with an explicit package name of ""
+    (e.g. '||::FOO) now works corectly.  (reported by Henrik Motakef)
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** NIL is now allowed as a structure slot name.
+    ** arbitrary numbers, not just reals, are allowed in certain
+       circumstances in LOOP for-as-arithmetic clauses.
+    ** multiple class redefinitions before slot access no longer
+       causes a type error.
+    ** (SETF FIND-CLASS) now accepts NIL as an argument to remove the
+       association between the name and a class.
+    ** generic functions with non-standard method-combination and over
+       five methods all of which return constants no longer return NIL
+       after the first few invocations.  (thanks to Gerd Moellmann)
+    ** CALL-NEXT-METHOD with no arguments now passes the original
+       values of the arguments, even in the presence of assignment.
+    ** functions [N]SUBST*, LAST, NRECONC, [N]SUBLIS may return any
+       object.
+    ** DISASSEMBLE works with closures and funcallable instances.
+    ** ADD-METHOD now returns the generic function, not the new
+       method.
+    ** FIND-METHOD signals an error if the lengths of the specializers
+       is incompatible with the generic function, even if the ERRORP
+       argument is true.
+    ** TYPE-OF returns recognizeable subtypes of all built-in-types of
+       which its argument is a member.
+    ** DEFCLASS only redefines the class named by its class-name
+       argument if that name is the proper name of the class;
+       otherwise, it creates a new class.
+    ** SLOT-UNBOUND now correctly initalizes the CELL-ERROR-NAME slot
+       of the UNBOUND-SLOT condition to the name of the slot.
+    ** (SETF (AREF bv 0) ...) did not work for bit vectors.
+    ** SLOT-UNBOUND and SLOT-MISSING now have their return values
+       treated by SLOT-BOUNDP, SLOT-VALUE, (SETF SLOT-VALUE) and
+       SLOT-MAKUNBOUND in the specified fashion.
