+changes relative to sbcl-1.0.32:
+ * improvement: support O_LARGEFILE access to files larger than 2GB on
+ x86-64/linux. (thanks to Daniel Janus; launchpad bug #453080)
+ * new feature: SB-INTROSPECT:WHO-SPECIALIZES-DIRECTLY to get a list of
+ definitions for methods specializing on the passed class itself.
+ * new feature: SB-INTROSPECT:WHO-SPECIALIZES-GENERALLY to get a list of
+ definitions for methods specializing on the passed class itself, or on
+ subclasses of it.
+ * fixes and improvements related to Unicode and external formats:
+ ** the Unicode character database has been upgraded to the
+ Unicode 5.2 standard, giving names and properties to a number of new
+ characters, and providing a few extra characters with case
+ transformations.
+ ** improvement: restarts for providing replacement input/output on coding
+ errors for fd-stream external formats.
+ ** minor incompatible change: the utf-8 external format now correctly
+ refuses to encode Lisp characters in the surrogate range (char-codes
+ between #xd800 and #xdfff).
+ ** fix a typo preventing conversion of strings into octet vectors
+ in the latin-2 encoding. (reported by Attila Lendvai; launchpad bug
+ #471689)
+ ** fix a bug in the octet multibyte handling of decoding errors and the
+ USE-VALUE restart. (launchpad bug #314939)
+ ** fix the bug underlying the expected failure in the FORCE-END-OF-FILE
+ restart on fd-stream decoding errors.
+ ** fix a bug in the ATTEMPT-RESYNC fd-stream decoding restart when the
+ error is near the end of file
+ ** fix a double-error case in unibyte octet conversions, when the first
+ use of USE-VALUE is ignored.
+ * enhancement: SB-INTROSPECT:ALLOCATION-INFORMATION also reports if the
+ object is allocated in a boxed region of dynamic space.
+ * bug fix: uses of slot accessors on specialized method parameters within
+ the bodies of SLOT-VALUE-USING-CLASS methods no longer triggers a type
+ error while finalizing the class. This fix may cause classes with slot
+ accessors to be finalized later than previously. (reported by Lars Rune
+ Nøstdal; launchpad bug #473699)
+ * bug fix: restore buildability on the MIPS platform. (regression from
+ 1.0.30.38, reported by Samium Gromoff)
+ * bug fix: inspecting closures is less likely to fail with a type error.
+ * bug fix: no timer starvation when setting the system clock back.
+ (launchpad bug #460283)
+ * bug fix: WITH-STANDARD-IO-SYNTAX now binds *PRINT-PPRINT-DISPATCH* to the
+ standard pprint dispatch table as specified by CLHS.
+ * bug fix: give CLISP a hint about a type declaration to enable it to build
+ the cross-compiler without warnings. (thanks to Josh Elasser; launchpad
+ bug #396597)
+

+ lambda-lists. (reported by Peter Seibel)
+ * bug fix: SAVE-LISP-AND-DIE option :SAVE-RUNTIME-OPTIONS did not work
+ correctly when starting from an executable core without saved runtime
+ options (reported by Faré Rideau, thanks to Zach Beane)
+ * bug fix: (SETF SLOT-VALUE) signalled a warning which should have been
+ an optimization note instead. (reported by Martin Cracauer)
+ * bug fix: WITH-SLOTS did not work with THE forms. (thanks to David Tolpin)
+ * bug fix: Have RUN-PROGRAM with :INPUT T only run the subprocess in a
+ new process group if it doesn't need to share stdin with the sbcl
+ process. (thanks to Leslie Polzer)
+ * bug fix: SATISFIES could be misoptimized to refer to a local function.
+ (reported by Stanislaw Halik)
+
+changes in sbcl-1.0.31 relative to sbcl-1.0.30:
+ * improvement: stack allocation is should now be possible in all nested
+ inlining cases: failure to stack allocate when equivalent code is manually
+ open coded is now considered a bug.
+ * improvements related to Unicode:
+ ** the Unicode character database has been upgraded to the
+ Unicode 5.1 standard, giving names and properties to a number of new
+ characters, and providing a few extra characters with case
+ transformations.
+ ** the system now recognizes and produces names for Unicode Hangul
+ syllable characters.
+ ** the EBCDIC-US external-format is now supported for octet operations
+ (as well as for stream operations).
+ * new feature: experimental :EMIT-CFASL parameter to COMPILE-FILE can
+ be used to output toplevel compile-time effects into a separate .CFASL
+ file.
+ * optimization: COERCE to VECTOR, STRING, SIMPLE-STRING and recognizable
+ one-dimenstional subtypes of ARRAY is upto 70% faster when the coercion is
+ actually needed.

+ faster.

+ multiplication by reciprocal when an exact reciprocal exists.
+ * optimization: multiplication of single- and double-floats floats by
+ constant two has been optimized.
+ * optimization: ARRAY-IN-BOUNDS-P is resolved at compile-time when
+ sufficient type information is available. (thanks to Leslie Polzer)
+ * optimization: SLOT-VALUE and (SETF SLOT-VALUE) with constant slot names on
+ known structure objects are as efficient as defstruct generated accessors.
+ * optimization: unused vector creation can now be optimized away.
+ * improvement: ASDF systems can now depends on SB-INTROSPECT.
+ * improvement: a STYLE-WARNING is signalled when a generic function
+ clobbers an earlier FTYPE proclamation.

+ generic function across method addition and removal even in the
+ absence of an explicit DEFGENERIC.
+ * improvement: DESCRIBE now reports on symbols naming undefined
+ but assumed or declared function as well.
+ * improvement: recompilation of systems using SB-GROVEL now works
+ (thanks to Leslie Polzer)
+ * improvements to SB-CLTL2 (thanks to Larry D'Anna):
+ ** functions DECLARATION-INFORMATION, PARSE-MACRO, and ENCLOSE have been
+ documented.
+ ** AUGMENT-ENVIRONMENT and DEFINE-DECLARATION have been implemented.

+ well as user defined declaration names.
+ ** VARIABLE-INFORMATION is now aware of alien variables.

+ as well. (reported by Josh Elsasser)
+ * bug fix: DELETE-FILE on streams no longer closes the stream with :ABORT T,
+ leading to possible attempts to delete the same file twice. See docstring
+ on DELETE-FILE for details. (reported by John Fremlin)
+ * bug fix: DELETE-FILE once again deletes the file named by the pathname
+ designator argument, rather than its truename. (reported by Luis
+ Oliveira)
+ * bug fix: the low-level debugger had 32-bit assumptions and was missing
+ information about some array types. (thanks to Luis Oliveira)
+ * bug fix: moderately complex combinations of inline expansions could
+ be miscompiled if the result was declared to be dynamic extent.
+ * bug fix: on x86, SAP-REF of sizes greater than 8 bits with offsets of the

+ circumstances.
+ * bug fix: in some cases no compiler note about failure to stack allocate
+ was emitted, even if the objects were in fact heap allocated.

+ allocation could cause objects users might reasonably expect to
+ be heap allocated to be stack allocated.
+ * bug fix: DESCRIBE signalled an error for generic functions under
+ certain circumstances. (thanks to Leslie Polzer)
+ * bug fix: Fixed spelling of an error message.
+

+ keywords is an order of magnitude faster.
+ * optimization: MAKE-INSTANCE with constant keyword arguments is x2-4 faster
+ in the presence of :AROUND or non-standard primary INITIALIZE-INSTANCE
