+changes in sbcl-0.8.2 relative to sbcl-0.8.1:
+ * fixed bug 148: failure to inline-expand a local function left
+ garbage, confusing the compiler.
+ * fixed bugs 3cd: structure slot readers perform type check if the
+ slot can have an invalid value (i.e. it is either not initialized
+ or can be written with a less specific slot writer).
+ * bug fix: the compiler now traps array references to elements off
+ the end of an array; previously, the bounds checking in some
+ circumstances could go off-by-one.
+ * improved MACHINE-VERSION, especially on Linux (thanks to Lars
+ Brinkhoff)
+ * type declarations for array element types now obey the description
+ on the CLHS page "Declaration TYPE", as per discussions on
+ sbcl-help around 2003-05-08. This means that a declaration
+ (TYPE (ARRAY FOO) BAR) means that, within the scope of the
+ declaration, all references to BAR will be asserted or assumed
+ (with THE, so dependent on compiler policy) to involve objects of
+ type FOO. Note that no such declaration is implied in
+ (MAKE-ARRAY .. :ELEMENT-TYPE 'FOO).
+ * declared types of functions from the "Conditions"
+ chapter. (reported by Paul Dietz)
+ * bug fix: CERROR accepts a function as its first argument.
+ * bug fix: NTH an NTHCDR accept a bignum as index
+ arguments. (reported by Adam Warner)
+ * optimization: character compare routines now optimize comparing
+ against a constant character. (reported by Gilbert Baumann)
+ * bug fix: (SETF AREF) on byte-sized-element arrays with constant index
+ argument now works properly on the MIPS platform.
+ * fixed compiler failure on (TYPEP x '(NOT (MEMBER 0d0))).
+ * repeated evaluation of the same DEFSTRUCT, a slot of which is
+ declared to have a functional type, does not cause an error
+ anymore.
+ * fixed bug: sometimes MAKE-INSTANCE did not work with classes with
+ many :DEFAULT-INITARGS. (reported by Istvan Marko)
+ * fixed bug: if last continuation of a deleted block has a
+ destination, this destination should be deleted too. (reported by
+ ohler on #lisp)
+ * fixed a bug in the bootstrap process: the host compiler's values
+ of ARRAY-DIMENSION-LIMIT and ARRAY-TOTAL-SIZE-LIMIT no longer leak
+ into the newly-built SBCL. (reported by Eric Marsden on #lisp,
+ test case from Patrik Nordebo)
+ * improved the ability of the disassembler on the PPC platform to
+ provide helpful disassembly notes.
+ * SB-MOP:CLASS-PROTOTYPE on built-in-classes returns an instance of
+ the class in more cases than previously.

+changes in sbcl-0.8.3 relative to sbcl-0.8.2:
+ * SBCL now builds and runs on MacOS X (version 10.2), or perhaps
+ more accurately, on the Darwin kernel running on PowerPC hardware.
+ (thanks to Brian Mastenbrook, Pierre Mai and Patrik Nordebo)
+ * Compiler code deletion notes now signal a condition of type
+ SB-EXT:CODE-DELETION-NOTE (a subtype of SB-EXT:COMPILER-NOTE) with
+ an associated MUFFLE-WARNING restart.
+ * The compiler now performs limited argument count validation of
+ constant format strings in FORMAT, and where appropriate in ERROR,
+ CERROR and WARN. (thanks to Gerd Moellmann)
+ * New ASDF-INSTALL contrib can be used for automatic download and
+ installation of third-party Lisp code from CCLAN or other sites
+ via CLiki
+ * Threaded builds (:SB-THREAD) now support SB-THREAD:INTERRUPT-THREAD,
+ which forces another thread to execute a function supplied by the
+ caller
+ * bug 75 fix: WITH-OUTPUT-TO-STRING (and MAKE-STRING-OUTPUT-STREAM) now
+ accept and act upon their :ELEMENT-TYPE keyword argument.
+ (reported by Martin Atzmueller, Edi Weitz)
+ * bug fix: FILE-POSITION now accepts position designators up to
+ ARRAY-DIMENSION-LIMIT or the extreme of the off_t range, whichever
+ is the greater. (thanks to Patrik Nordebo)
+ * bug fix: MAKE-ARRAY ignored :INITIAL-CONTENTS NIL. (reported by
+ Kalle Olavi Niemitalo)

+ off_t, including Darwin and FreeBSD. (thanks to Andreas Fuchs)
+ * x86 bug fix in control stack exhaustion checking: now shows backtrace
+ * bug fix in WITH-TIMEOUT: now the body can have more than one form.
+ (thanks to Stig Sandoe)
+ * bug fix in READ-SEQUENCE: READ-SEQUENCE following PEEK-CHAR or
+ UNREAD-CHAR now correctly includes the unread character in the
+ target sequence. (thanks to Gerd Moellmann)
+ * bug fix in threaded builds: the system can now be suspended and
+ resumed by shell job control with minimal disruption.
+ * new optimization: inside a named function any reference to a
+ function with the same name is considered to be a self-reference;
+ this behaviour is controlled with SB-C::RECOGNIZE-SELF-CALLS
+ optimization quality.
+ * new optimization on x86: logical functions and + now have
+ optimized (UNSIGNED-BYTE 32) versions, which are automatically
+ used when the result is truncated to 32 bits.
+ * VALUES declaration is partially enabled.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** The system now obeys the constraint imposed by
+ UPGRADED-ARRAY-ELEMENT-TYPE that the upgraded array element
+ types form a lattice under type intersection.
+ ** FFLOOR, FTRUNCATE, FCEILING and FROUND work with integers.
+ ** ASSOC now ignores NIL elements in an alist.
+ ** CEILING now gives the right answer with MOST-NEGATIVE-FIXNUM
+ and (1+ MOST-POSITIVE-FIXNUM) answers.
+ ** The addition of a method with invalid qualifiers to a generic
+ function does not cause an error to be signalled immediately;
+ a warning is signalled, and the error is generated only on
+ calling the generic function.
