+changes in sbcl-0.9.14 relative to sbcl-0.9.13:
+ * minor incompatible change: prevent the user from specializing the
+ new-value argument to SB-MOP:SLOT-VALUE-USING-CLASS. It's
+ somewhat counter to the intent of the protocol, I (CSR) think, and
+ additionally it just doesn't work in SBCL as currently
+ implemented, thanks to optimizations (that are always valid for
+ the other three SLOT-VALUEish functions, but not for the setter).
+ * bug fix: unparsing logical pathnames with :NAME :WILD :TYPE NIL
+ failed with a type error. (reported by Pascal Bourguignon)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** MISC.641: LET-conversion were not supposed to work in late
+ compilation stages.
+
+changes in sbcl-0.9.13 relative to sbcl-0.9.12:
+ * new feature: source path information is generated for macro-expansion
+ errors for use in IDE's like Slime (thanks to Helmut Eller)
+ * bug fix: calls to the compiler no longer modify *RANDOM-STATE*
+ * bug fix: compiler does not loop forever on an invalid type in
+ TYPEP.
+ * improvement: compilation of most CLOS applications is significantly
+ faster
+ * optimization: added a limited bytecode compiler for simple toplevel
+ forms, speeding up compilation and FASL loading
+
+changes in sbcl-0.9.12 relative to sbcl-0.9.11:
+ * minor incompatible change: in sbcl-0.9.11 (but not earlier
+ versions) SB-MOP:FINALIZE-INHERITANCE would recursively descend
+ into subclasses of the finalized class. Now user calls to
+ FINALIZE-INHERITANCE finalize just the one class, and calls by the
+ system return before any subclasses are finalized.
+ * minor incompatible change: The reader no longer ignores errors
+ regarding non-existent packages in #+ and #- feature tests.
+ * new feature: command line options --no-sysinit, --no-userinit to
+ inhibit loading the corresponding init files
+ * new feature: add a generic function SOCKET-SEND to SB-BSD-SOCKETS,
+ for sending data through UDP sockets (thanks to François-René Rideau)
+ * minor incompatible change: SIGPIPE is ignored and "Broken pipe"
+ error is signalled instead (thanks to François-René Rideau)
+ * minor incompatible change: Error signalling behaviour of lexical
+ operations violating package locks has changed slightly. Refer to
+ documentation on package locks for details.
+ * enhancement: EVAL can process IF-expressions without resorting to the
+ compiler.
+ * bug fix: Some operations involving SIN, COS, or TAN weren't being
+ constant-folded properly due to missing out-of-line functions.
+ (reported by Mika Pihlajamäki)
+ * bug fix: LISTEN sometimes returned T even in cases where no data was
+ immediately available from the stream
+ * fixed bug: types of the last two arguments to SET-SYNTAX-FROM-CHAR
+ were reversed. (reported by Levente Mészáros)
+ * fixed bug: Tests for the (VECTOR T) type gave the wrong answer
+ when given a vector displaced to an adjustable array. (reported
+ by Utz-Uwe Haus)
+ * bug fix: derivation of float boundaries from numbers outside the
+ appropriate float range (reported by John Wiseman)
+ * bug fix: MAKE-LOAD-FORM-SAVING-SLOTS accepts en empty slot name
+ list.
+ * bug fix: precomputing cache entries for generic functions with
+ some subclasses of specializers as yet invalid does not attempt to
+ fill a cache line with a negative offset. (reported by Levente
+ Mészároz)
+ * improvements to DOCUMENTATION for TYPE and STRUCTURE doc-types:
+ allow condition class objects as arguments to DOCUMENTATION and
+ (SETF DOCUMENTATION); only find and set documentation for
+ structure names for the STRUCTURE doc-type. (suggested by Gary
+ King)
+ * improvements to the Win32/x86 port:
+ ** (user-homedir-pathname) and default initialization file
+ locations now know about the user's "Documents and Settings"
+ directory (thanks to Yaroslav Kavenchuk)
+ ** run-program is implemented (thanks to Mike Thomas)
+ ** sockets support (thanks to Timothy Ritchey)
+ ** better backtrace support (thanks to Alastair Bridgewater)
+ ** sb-grovel supported
+ ** asdf-install and sb-posix work somewhat
+ ** capable of running Slime using SWANK:*COMMUNICATION-STYLE* NIL
+ * improvements to the Solaris/x86 port:
+ ** works on Solaris 11/Solaris Express
+ ** floating-point exception handling support
+ ** support for the breakpoint-based TRACE :ENCAPSULATE NIL facility
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** REMOVE-METHOD returns its generic function argument even when
+ the method is not one of the generic functions' methods.
+ ** objects declared as MEMBER types can be admissible arguments to
+ structure accessors.
+ ** printing characters should simply be printed by the FORMAT ~:C
+ directive.
+ ** compiler failure when compiling functions with hairy constant
+ defaults for optional parameters.
+ ** compiler produces wrong code when MAYBE-INLINE-expanding a
+ function, which is already optimized.
+
+changes in sbcl-0.9.11 relative to sbcl-0.9.10:
+ * new platform: experimental support for SBCL x86/Darwin, including
+ MacOS X 10.4.5 on Intel.
+ * new feature: Unicode character names are now known to the system
+ (through CHAR-NAME and NAME-CHAR).
+ * new feature: the filesystem location of SBCL's core file is
+ exposed to lisp through the variable SB-EXT:*CORE-PATHNAME*.
+ * minor incompatible change: the contrib modules SB-POSIX and
+ SB-BSD-SOCKETS no longer depend on stub C libraries; the intent of
+ this change is to make it easier to distribute
+ location-independent binaries.
+ * bug fix: as implied by AMOP, standardized classes no longer have
+ slots named by external symbols of public packages. (reported by
+ Pascal Costanza)
+ * optimization: calling functions via constant symbols -- as in
+ (FUNCALL 'FOO) -- is now roughly as efficient as calling them
+ via the function object as in (FUNCALL #'FOO).
+ * optimization: on x86 and x86-64, the calling convention for the
+ case of dealing with an unknown number of values has been altered
+ to be friendlier to the prediction heuristics implemented,
+ particularly with reference to CALL and RET pairing. (thanks to
+ Alastair Bridgewater)
+ * optimization: on x86, the code for access to thread-local symbol
+ values and binding/unbinding of thread-local symbols is smaller.
+ (thanks to Alastair Bridgewater)
+ * enhancement: CONSTANTP is now able to determine constantness of
+ more complex forms, including calls to constant-foldable standardized
+ functions and some special forms beyond QUOTE.
+ * fixed bug: occasional GC crashes on Solaris/x86
+ * optimization: x86-64 supports stack allocation of results of simple
+ calls of MAKE-ARRAY, bound to variables, declared DYNAMIC-EXTENT
+ * enchancement: the PROCESS-INPUT and -OUTPUT streams created by
+ SB-EXT:RUN-PROGRAM can be used for both character and byte IO
+ (thanks to James Knight)
+ * fixed bug: CL:LISTEN always returns NIL at end of file, as required
+ by the standard (thanks to Stephen Compall)
+
+changes in sbcl-0.9.10 relative to sbcl-0.9.9:
+ * new feature: new SAVE-LISP-AND-DIE keyword argument :EXECUTABLE can
+ be used for bundling the runtime and the core file into one
+ executable binary. This feature is not currently supported on all SBCL
+ platforms. (thanks to James Bielman and NIIMI Satoshi)
+ * new feature: a generational or ephemeral garbage collector is now
+ the default on the PowerPC platform (both Linux and Darwin). The
+ old Cheney (stop and copy) collector is a build-time option.
+ (thanks to Cyrus Harmon, after Raymond Toy)
+ * minor incompatible change: the method by which SBCL finds its
+ contributed modules has changed; it no longer relies on symbolic
+ links from an $SBCL_HOME/systems directory, but searches directly
+ in the subdirectories of $SBCL_HOME.
+ * enhancement: the dynamic heap size on the Linux/PPC platform is
+ markedly larger, even using the older Cheney garbage collector.
+ * fixed bug #399: full call to DATA-VECTOR-REF in accesses to
+ certain complicated string types. (reported by Gary King)
+ * fixed bug: STRING-TO-OCTETS and OCTETS-TO-STRING did not convert
+ character codes. (thanks to Yaroslav Kavenchuk and Ivan Boldyrev)
+ * fixed bug: DOCUMENTATION on structures no longer signals an
+ error if no structure type of the right name exists. (reported by
+ Glenn Ehrlich)
+ * fixed bug: compiled calls to MAKE-INSTANCE where there is an
+ applicable non-standard primary or :AROUND method on
+ INITIALIZE-INSTANCE or SHARED-INITIALIZE and a non-keyword initarg
+ no longer cause unbound variable errors. (reported by Kevin Reid)
+ * fixed bug: metacircle resolution in cases where methods have slots
+ added before the slots from STANDARD-METHOD. (reported by Jean
+ Bresson)
+ * fixed bug: the Power PC assembly code for calling into lisp
+ sometimes computed its return address wrongly (depending on the
+ 15th bit of the address, fixed at link time). This used to
+ manifest itself in a segmentation violation while building PCL.
+ (reported by Kevin Rosenberg, Eric Marsden, Lars Brinkhoff and
+ many others over the years)
+ * fixed bug: ROOM no longer reports silly numbers for stack usage if
+ the stack pointer (treated as a signed integer) is negative.
+ (thanks to Peter van Eynde)
+
+changes in sbcl-0.9.9 relative to sbcl-0.9.8:
+ * new platform: experimental support for the Windows operating
+ system has been added. (thanks to Alastair Bridgewater)
+ * fixed several bugs in and robustified the PPC FFI (including
+ callbacks). (thanks to Cyrus Harmon and Heiner Schwarte)
+ * bug fix: allow non-simple string symbol names (reported by Paul
+ Dietz)
+ * bug fix: interrupt handling on NetBSD (thanks to Richard M
+ Kreuter)
+ * bug fix: saving a core corrupted callbacks on x86/x86-64
+ * bug fix: closed a loophole in metacircularity detection and
+ grounding in the PCL implementation of CLOS.
+ * bug fix: TRUENAME on "/" no longer returns a relative pathname.
+ (reported by tomppa on #lisp)
+ * bug fix: clear the direction flag on Lisp -> C transitions, as
+ required by the x86-64 ABI. Fixes mysterious GC crashes on SuSE.
+ (reported by Andrej Grozin and Hendrik Maryns)
+ * optimization: major improvements to GC efficiency on GENCGC platforms
+ * optimization: faster implementation of EQUAL
+ * optimization: emit more efficient opcodes for some common
+ immediate->register MOV instructions on x86-64. (thanks to Lutz Euler)
+ * optimization: several other minor code-generation improvements on x86-64
+ * fixed segfaults on x86 FreeBSD 7-current. (thanks to NIIMI Satoshi)
+
changes in sbcl-0.9.8 relative to sbcl-0.9.7:
+ * minor incompatible change: (SETF CLASS-NAME) and (SETF
+ GENERIC-FUNCTION-NAME) are generic functions once more (reverting
+ the change in the 0.9.7 release). (SETF CLASS-NAME) is specified
+ by ANSI as a generic function, and for consistency (SETF
+ GENERIC-FUNCTION-NAME) is treated likewise.
+ * fixed bug #233.b: make constraint propagation notice when a variable
+ value is changed after it is referenced but before it is used
+ * fixed bug #296: no more arbitrary behaviour from filenames with
+ odd characters as --load arguments. (reported by Adam Warner)
+ * fixed bug #390: :CHARACTER-SET pathname components now work as
+ expected. (reported by Tim Daly Jr)
* fixed bug #391: complicated :TYPE intersections in slot
definitions no longer cause an error in PCL internals.
+ * fixed bug #392: plugged a hole in the obsolete-instance protocol.
* bug fix: FILE-STRING-LENGTH is now external-format sensitive,
returning the number of octets which would be written to the
file-stream. (thanks to Robert J. Macomber)
-
+ * bug fix: the SB-SIMPLE-STREAMS contrib passes external-format
+ arguments to the internal stream functions. (thanks to David
+ Lichteblau)
+ * bug fix: stack exhaustion is now handled on the x86/SunOS
+ platform. (thanks to Daisuke Homma)
+ * bug fix: more accurate ROOM results on GENCGC platforms
+ * optimization: improved type inference for arithmetic-for
+ index variables in LOOP
+ * optimization: faster floating-point SQRT on x86-64
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** DOCUMENTATION returns NIL instead of "" for method combinations
+ that don't have a docstring
