+changes relative to sbcl-1.0.33:
+ * enhancement: SB-INTROSPECT:DEFTYPE-LAMBDA-LIST now also works on most
+ builtin types.
+ * enhancement: Errors during compile-time-too processing (i.e. EVAL-WHEN)
+ are now caught and reported just like errors during macroexpansion.
+ * fixes and improvements related to Unicode and external formats:
+ ** bug fix: error handling and restart usage in the ucs-2 external format
+ has been improved.
+ ** there is now an implementation of the ucs-4 external format.
+ * bug fix: #p"\\\\" can now be read without error on Win32. (reported by
+ Willem Broekema; launchpad bug lp#489698).
+ * bug fix: some minor code rearrangements to reenable warning-free building
+ from CMUCL (reported by xme@gmx.net; launchpad bug lp#491104)
+ * bug fix: PRINT-OBJECT for clos instances respects the right margin when
+ pretty printing
+
+changes in sbcl-1.0.33 relative to sbcl-1.0.32:
+ * new port: support added for x86-64 NetBSD. (thanks to Aymeric Vincent)
+ * improvement: support O_LARGEFILE access to files larger than 2GB on
+ x86-64/linux. (thanks to Daniel Janus; launchpad bug lp#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.
+ * new build flag: :sb-xref-for-internals; SBCL will collect xref information
+ about itself during the build (e.g. for M-? in Slime), if this flag is
+ enabled in customize-target-features.lisp. This will increase the core
+ size by about 5-6mb, though, so it's mostly interesting to SBCL
+ developers.
+ * new feature: various GENCGC tuning parameters have been experimentally
+ documented and exported from SB-EXT. See documentation for details.
+ * 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.
+ ** improvement: where :<encoding> is a keyword corresponding to an
+ external format the system supports, it is now possible to specify
+ (:<encoding> :replacement <character>) as an external format which will
+ automatically substitute <character> on encoding or decoding errors for
+ streams and for STRING-TO-OCTETS and its inverse. (launchpad bug
+ lp#317072)
+ ** improvement: the file streams underlying the standard streams (such as
+ *STANDARD-INPUT*, *TERMINAL-IO*) are opened with an external format
+ which uses the replacement mechanism to handle encoding errors,
+ preventing various infinite error chains and unrecoverable I/O
+ confusion.
+ ** 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
+ lp#471689)
+ ** fix a bug in the octet multibyte handling of decoding errors and the
+ USE-VALUE restart. (launchpad bug lp#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.
+ ** fix bugs in handling of undefined code points in unibyte encodings.
+ ** fix LISTEN (and consequent hangs in READ-CHAR-NO-HANG) on bivalent
+ streams after an UNREAD-CHAR.
+ * enhancement: SB-INTROSPECT:ALLOCATION-INFORMATION also reports if the
+ object is allocated in a boxed region of dynamic space.
+ * enhancement: SB-POSIX:FORK now signals an error if an attempt to
+ fork with multiple Lisp threads running is made, instead of going
+ ahead with unpredictable consequences. (reported by Leslie Polzer)
+ * 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 lp#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 lp#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 lp#396597)
+ * bug fix: correctly dump literal objects in defaulting forms of arglists.
+ (reported by Attila Lendvai; launchpad bug lp#310132)
+ * bug fix: distinguish in type specifiers between arrays that might be
+ complex and arrays that are definitely complex. (launchpad bug lp#309129)
+ * bug fix: SUBTYPEP knows that the SYMBOL type is not SUBTYPEP the KEYWORD
+ type. (reported by Levente Mészáros; launchpad bug lp#485972)
+ * bug fix: setting the value of a symbol-macro within a method in the
+ presence of type declarations works properly again. (reported by Iban
+ Hatchondo; launchpad bug lp#485019)
+
+changes in sbcl-1.0.32 relative to sbcl-1.0.31:
+ * optimization: faster FIND and POSITION on strings of unknown element type
+ in high SPEED policies. (thanks to Karol Swietlicki)
+ * optimization: faster CONCATENATE 'STRING in low SPEED policies (reported
+ by David Vázquez)
+ * improvement: better error signalling for bogus parameter specializer names
+ in DEFMETHOD forms (reported by Pluijzer)
+ * bug fix: DELETE-FILE once again works on logical pathnames (regression
+ since 1.0.30.49)
+ * bug fix: LOGICAL-PATHNAME signals a TYPE-ERROR if pathspec is specified
+ incorrectly.
+ * bug fix: redefinition of a class via DEFCLASS without :DEFAULT-INITARGS
+ removes previous default initargs (reported by Lars Rune Nøstdal and
+ Samium Gromoff)
+ * bug fix: correct WHO-CALLS information for inlined lambdas with complex
+ 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.
+ * optimization: TRUNCATE on known single- and double-floats is upto 25%
+ faster.
+ * optimization: division of floating point numbers by constants uses
+ 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.
+ * improvement: the compiler is able to track the effective type of
+ 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.
+ ** DECLARATION-INFORMATION now supports declaration name DECLARATION as
+ well as user defined declaration names.
+ ** VARIABLE-INFORMATION is now aware of alien variables.
+ * improvement: improved address space layout on OpenBSD (thanks to Josh
+ Elsasser)
+ * improvement: pretty-printing of various Lisp forms has been improved
+ (thanks to Tobias Rittweiler)
+ * bug fix: calls to DECODE-FLOAT and INTEGER-DECODE-FLOAT whose value was
+ unused were deleted in safe code. (reported by John Fremlin)
+ * bug fix: a failing AVER compiling certain MAKE-ARRAY forms. (reported
+ by James Wright)
+ * bug fix: some out-of-line array predicates were missing (reported by
+ Stelian Ionescu)
+ * bug fix: a failing AVER in CONVERT-MV-CALL has been fixed. (thanks to
+ Larry D'Anna)
+ * bug fix: a failing AVER in %ALLOCATE-CLOSURES conversion has been fixed
+ (thanks to Larry D'Anna)
+ * bug fix: SLEEP supports times over 100 million seconds on long on OpenBSD
+ 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
+ form (+ <variable> <integer>) were miscompiled under certain
+ 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.
+ * bug fix: minor violation of "otherwise inaccessible" rule for stack
+ 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.
