+changes in sbcl-0.9.11 relative to sbcl-0.9.10:
+ * new feature: Unicode character names are now known to the system
+ (through CHAR-NAME and NAME-CHAR).
+ * bug fix: as implied by AMOP, standardized classes no longer have
+ slots named by external symbols of public packages. (reported by
+ Pascal Costanza)
+
+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
+\a
+changes in sbcl-0.9.7 relative to sbcl-0.9.6:
+ * minor incompatible change: (SETF CLASS-NAME) and (SETF
+ GENERIC-FUNCTION-NAME) are no longer generic functions, and
+ therefore are not customizeable by user code (as seems to be at
+ least permitted and maybe required by AMOP). As a consolation,
+ however, the SBCL implementation of these functions now calls
+ REINITIALIZE-INSTANCE as specified by AMOP.
+ * bug fix: slot-definition documentation is propagated as per ANSI
+ 7.6.2 to EFFECTIVE-SLOT-DEFINITIONS.
+ COMPUTE-EFFECTIVE-SLOT-DEFINITION now receives a :DOCUMENTATION
+ argument, as do eslotd initialization methods. (from Pascal
+ Costanza's "Closer" project)
+ * bug fix: REINITIALIZE-INSTANCE on generic functions calls
+ COMPUTE-DISCRIMINATING-FUNCTION (almost) unconditionally, as
+ specified by AMOP.
+ * bug fix: it is now possible to have more than one subclass of
+ STANDARD-GENERIC-FUNCTION without causing stack overflow.
+ (reported by Bruno Haible, Pascal Costanza and others)
+ * bug fix: the dependent update protocol now works for generic
+ functions. (thanks to Gerd Moellmann; reported by Bruno Haible
+ and Pascal Costanza)
+ * bug fix: condition-class instances corresponding to
+ DEFINE-CONDITION forms are now created eagerly. (reported by
+ Kalle Olavi Niemitalo on comp.lang.lisp)
+ * bug fix: floating point printing is more accurate in some
+ circumstances. (thanks to Simon Alexander)
+ * bug fix: *COMPILE-FILE-PATHNAME* now contains the user's pathname
+ merged with *DEFAULT-PATHNAME-DEFAULTS*.
+ * bug fix: callbacks on OS X now preserve stack-alignment.
+ (thanks to Cyrus Harmon)
+ * enhancement: the x86-64 disassembler is much better at
+ disassembling SSE instructions. (thanks to Lutz Euler)
+ * enhancement: CHECK-TYPE on a variable now allows type-inference
+ (thanks to Vincent Arkesteijn)
+ * optimization: improved performance of EUC-JP external format.
+ (thanks to NIIMI Satoshi)
+ * optimization: performance improvements to IO on file streams of
+ :ELEMENT-TYPE CHARACTER
+ * optimization: much faster memory allocation on x86-64
+ * optimization: faster garbage collections (latency and throughput)
+ on gencgc
+ * optimization: faster bignum subtraction and division on x86 and x86-64
+ (thanks to Lutz Euler)
+ * optimization: more accurate type-inference for loops that use a
+ floating point index variable or a negative step.
+
changes in sbcl-0.9.6 relative to sbcl-0.9.5:
* bug fix: add a workaround to SBCL looping infinitely at startup on
Linux kernels with apparently buggy implementations of personality().
on platforms supporting dynamic-extent allocation.
* enhancement: saving cores with foreign code loaded is now supported
on MIPS/Linux in addition to the previously supported platforms.
+ * bug fix: FIND-RESTART now tests for activity, not applicability when given
+ a restart object as identifier. (reported by Helmut Eller for CMUCL)
* bug fix: division by zero in sb-sprof when no samples were collected
* bug fix: a race when a slow to arrive sigprof signal killed sbcl
* bug fix: asdf-install uses CRLF as required by the HTTP spec.
- (thanks to Alexander Kjeldaas)
+ (thanks to Alexander Kjeldaas)
* new feature: ignoring the return values of destructive functions
like NREVERSE signals a compile-time style-warning.
(thanks to Kevin Reid)
+ * new feature: the alignment of alien structure fields can be
+ explicitly specified. (thanks to Cyrus Harmon)
+ * bug fix: run cleanup forms (in all threads) when receiving a SIGTERM
+ and dump core on SIGQUIT
* threads
+ ** incompatible change: threads do not inherit values of specials
+ from their parents (see manual)
** bug fix: threads stacks belonging to dead threads are freed by the
next exiting thread, no need to gc to collect thread stacks anymore
** minor incompatible change: INTERRUPT-THREAD-ERROR-ERRNO removed
** WITH-RECURSIVE-LOCK can be nested in a WITH-MUTEX for the same lock
** bug fix: dynamic variable and thread start related gc lossage
+ ** bug fix: job control (SIGSTOP/SIGCONT) no longer confuses threads
+ suspended for gc
* fixed some bugs revealed by Paul Dietz' test suite:
** SUBTYPEP is slightly more accurate on heinously complicated
CONS types where some of the members have uncertain (in the
NIL, NIL sense) type relationships to each other.
+ * GENCGC
+ ** Cores produced by SAVE-LISP-AND-DIE on GENCGC platforms are
+ no longer purified unless :PURIFY T is explicitly specified.
+ ** Non-purified cores are significantly smaller than before
changes in sbcl-0.9.5 relative to sbcl-0.9.4:
* new feature: timers based on Zach Beane's excellent timer package
(thanks to Richard Kreuter)
* bug fix: defining classes whose accessors are methods on existing
generic functions in other (locked) packages no longer signals
- bogus package lock violations. (reported by François-René Rideau)
+ bogus package lock violations. (reported by François-René Rideau)
* bug fix: special variables as DEFMETHOD parameters no longer have
associated bogus type declarations. (reported by David Wragg and
Bruno Haible)
