    changes in sbcl-1.0.15 relative to sbcl-1.0.14:
  * enhancement: cleaner backtraces for interactive interrupts, as
    well as other cases where the interesting frames used to be
    obscured by interrupt handling frames.
  * enhancement: untracing a whole package using (UNTRACE "FOO") is
    now supported, and tracing a whole package using (TRACE "FOO") now
    traces SETF-functions as well.
  * enhancement: implement SB-POSIX:MKTEMP and SB-POSIX:MKDTEMP.
  * SB-DEBUG:PRINT-FRAME-CALL now prints the entry-point kind even
    when SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS* is NIL.
  * unreadably printed representation of hash-tables now includes
    weakness if any.
  * bug fix: partially fixed #188: type propagation from assignments
    is now more efficient.
  * bug fix: fixed #407: (COERCE X 'SINGLE-FLOAT) and (COERCE X
    'DOUBLE-FLOAT) are not flushable.
  * bug fix: on x86 and x86-64 pointer based EQ-hashing now uses the
    full address of the object, and none of the tag bits.
  * bug fix: readably printing hash-tables now respects other printer
    control variables.  (reported by Cedric St-Jean)
  * bug fix: compiler gave a bogus STYLE-WARNING for the :SYNCHRONIZED
    keyword with MAKE-HASH-TABLE.
  * bug fix: export SB-POSIX:MKSTEMP.
  * bug fix: SORT was not interrupt safe.
  * bug fix: XREF accounts for the last node of each basic-block as
    well.
  * bug fix: MAKE-INSTANCE optimizations interacted badly with
    non-keyword :DEFAULT-INITARGS in the presence of :BEFORE/:AFTER
    methods on SHARED-INITIALIZE.  (thanks to Matt Marjanovic)
  * bug fix: the CTOR optimization for MAKE-INSTANCE should no longer
    create obsolete instances in the case of redefinition or
    obsoletion of a superclass.  (thanks to Andy Hefner)
  * bug fix: Support for the Alpha architecture has been revived; it had
    suffered somewhat from lack of maintenance since sbcl-1.0.
  * improvements to the Windows port:
     ** The system detects the codepage to use at startup, instead of
        using the value from the saved core. (thanks to Kei Suzuki)

  • sbcl_1_0_14

    8679d281 · 1.0.14: release, will be tagged as sbcl_1_0_14 · 
    changes in sbcl-1.0.14 relative to sbcl-1.0.13:

  * fixed bug #402: proclaimed non-standard declarations in DEFMETHOD
    bodies no longer cause a WARNING to be signalled. (reported by
    Vincent Arkesteijn)
  * bug fix: (TRUNCATE X 0) when X is a bignum now correctly signals
    DIVISION-BY-ZERO. Similarly for MOD and REM (which suffered due to
    the bug in TRUNCATE.) (reported by Michael Weber)
  * bug fix: SB-SPROF:REPORT no longer signals an error if there are
    no samples. (reported by Andy Hefner)

  * DESCRIBE and (DOCUMENTATION ... 'OPTIMIZE) describe meaning of
    SBCL-specific optimize qualities.

  • sbcl_1_0_12

    f3a2d7fd · 1.0.12: release, will be tagged as sbcl_1_0_12 · 
    changes in sbcl-1.0.12 relative to sbcl-1.0.11:
  * new feature: MAKE-HASH-TABLE now experimentally accepts a
    :SYNCHRONIZED argument, which makes the hash-table safe for
    concurrent accesses (but not iteration.) See also:
    SB-EXT:WITH-LOCKED-HASH-TABLE, and
    SB-EXT:HASH-TABLE-SYNCHRONIZED-P.
  * optimization: CONCATENATE on strings is an order of magnitude faster
    in code compiled with (> SPEED SPACE).
  * optimization: SUBSEQ is ~50% faster on lists.
  * bug fix: bug 417 fixed -- source location reporting is now more robust.
  * bug fix: SUBSEQ on a list will now correctly signal an error if if
    END is smaller then START.
  * bug fix: SB-PROFILE will no longer report extra consing for nested
    calls to profiled functions.
  * bug fix: ROOM implementation had bogus fixnum declarations which
    could cause type-errors when calling ROOM on large images.
  * bug fix: if file compilation is aborted, the partial fasl is now
    deleted, and COMPILE-FILE returns NIL as the primary value.
  * bug fix: number of thread safety issues relating to SBCL's internal
    hash-table usage have been fixed.
  * bug fix: SB-SYS:WITH-PINNED-OBJECTS could cause garbage values to
    be returned from its body when the values were being returned
    using unknown-values return convection and the W-P-O was wrapped
    inside an UNWIND-PROTECT.
  * bug fix: sb-posix should now compile again under Windows, enabling
    slime to work again.

  • sbcl_1_0_11

    4266faf7 · 1.0.11: release, will be tagged as sbcl_1_0_11 · 
    changes in sbcl-1.0.11 relative to sbcl-1.0.10:
  * incompatible change: hash-table accessor functions are no longer
    automatically protected by locks. Concurrent accesses on the same hash-table
    from multiple threads can give inconsistent results or even corrupt the
    hash-table completely. Multi-threaded applications should do their own
    locking at the correct granularity. In the current implementation it is
    still safe to have multiple readers access the same table, but it's not
    guaranteed that this property will be maintained in future releases.
  * minor incompatible change: (SETF MUTEX-VALUE) is not longer supported,
    and will signal an error at runtime.
  * enhancement: SB-THREAD package now exports a semaphore interface.
  * enhancement: CONS can now stack-allocate on x86 and
    x86-64. (Earlier LIST and LIST* supported stack-allocation, but
    CONS did not.)
  * enhancement: nested lists can now be stack allocated on
    platforms providing stack allocation support.
  * enhancement: dynamic-extent support has been extended to support
    cases where there are multiple possible sources for the stack
    allocated value.
  * optimization: RELEASE-MUTEX no longer needs to perform a syscall
    if the mutex is uncontested on Linux.
  * bug fix: symbol-macro expansion now uses the *MACROEXPAND-HOOK*
    as specified by the CLHS. (thanks to Tobias Rittweiler)
  * bug fix: NaN comparison now works on x86-64.
  * bug fix: CLOSE :ABORT T on a stream with pending output now
    works.
  * bug fix: instances of non-standard metaclasses using standard
    instance structure protocol sometimes missed the slot type checks
    in safe code.
  * bug fix: known functions can be inlined in high-debug code.

  • sbcl_1_0_10

    7c95296b · 1.0.10: release, will be tagged as sbcl_1_0_10 · 
    changes in sbcl-1.0.10 relative to sbcl-1.0.9:
  * minor incompatible change: the MSI installer on Windows no longer
    associates .lisp and .fasl files with the installed SBCL.
  * minor incompatible change: :UNIX is no longer present in *FEATURES*
    on Windows. (thanks to Luis Oliviera)
  * new feature: SB-CLTL2 contrib module now implements
    FUNCTION-INFORMATION. (thanks to Larry D'Anna)
  * optimization: scavenging weak pointers is now more efficient,
    requiring O(1) instead of O(N) per weak pointer to identify
    scanvenged vs. unscavenged pointers. (thanks to Paul Khuong)
  * optimization: typechecking (SETF SLOT-VALUE) is now ~5x faster in
    method bodies using constant slot-names when the first argument is
    a specializer parameter for the method.
  * optimization: SLOT-VALUE &co are now ~50% faster for variable slot
    names, when the class of the instance is a direct instance
    STANDARD-CLASS or FUNCALLABLE-STANDARD-CLASS (making them only 3x
    as slow as the constant slot-name case.)
  * optimization: member type construction is now O(N) instead
    of O(N^2).
  * optimization: UNION and NUNION are now O(N+M) for large
    inputs as long as the :TEST function is one of EQ, EQL, EQUAL, or
    EQUALP.
  * enhancement: DEFINE-MODIFY-MACRO lambda-list information is
    now more readable in environments like Slime which display it.
    (thanks to Tobias C. Rittweiler)
  * bug fix: SB-EXT:COMPARE-AND-SWAP was non-atomic unless the compiler
    was able to infer the correct argument type for the object on which
    the CAS operation was being performed.
  * bug fix: copy propagation interfered with parallel assignment
    semantics in local calls. (reported by Paul Khuong)
  * bug fix: the signed modular fixnum shift compiled to wrong code on
    x86 and x86-64.  (spotted by a slight modification to some of
    PFD's random tests)

  • sbcl_1_0_9

    8396eebf · 1.0.9: release, will be tagged as sbcl_1_0_9 · 
    changes in sbcl-1.0.9 relative to sbcl-1.0.8:
  * minor incompatible change: SB-SYS:OUTPUT-RAW-BYTES is deprecated.
  * enhancement: SB-EXT:FINALIZE accepts a :DONT-SAVE keyword argument,
    indicating the finalizer should be cancelled when SAVE-LISP-AND-DIE
    is called.
  * enhancement: default PRINT-OBJECT methods for classes, slot-definitions,
    and generic function now print the object identity for anonymous
    instances. (thanks to Attila Lendvai)
  * enhancement: as an extension to MOP, SBCL now supports SETF of
    STANDARD-INSTANCE-ACCESS and FUNCALLABLE-STANDARD-INSTANCE-ACCESS.
    (thanks to Attila Lendvai)
  * enhancement: sb-cover has an alternate annotation mode which puts
    the form annotations at the car of the form, instead of annotating
    it completely. The benefit of this mode is that it shows better
    which forms were instrumented by the compiler.
  * bug fix: new compiler transforms for MEMBER and ASSOC were affected
    by printer control variables. (reported by Dan Corkill)
  * bug fix: system leaked memory when delayed output was performed by
    the OS in smaller chunks then expected. (thanks to David Smith)
  * bug fix: system leaked memory when file streams were not closed
    properly.
  * bug fix: large objects written to slow streams that were modified
    after the write could end up with the modified state written to
    the underlying file descriptor.
  * bug fix: multiple threads operating in parallel on the same stream
    could cause buffer-overflows.
  * bug fix: source location information is stored correctly
    (broken since 1.0.6). This bug would generally show up as the
    Slime debugger highlighting the wrong form when the sldb-show-source
    command was used.
  * bug fix: Branch forms are again annotated as branches in the sb-cover
    annotations.
  * bug fix: GCD on MOST-NEGATIVE-FIXNUM no longer causes an infinite loop
    on x86-64. (reported by Gregory Vanuxem)
  * bug fix: EQUALP could return wrong results for structures with raw
    slots (slots with a :TYPE of SINGLE-FLOAT, DOUBLE-FLOAT, or a machine
    word). (reported by Vjacheslav Fyodorov)
  * bug fix: sb-sprof sampling didn't work on non-x86oid platforms. (patch
    by Pierre Mai)

  • sbcl_1_0_8

    f9e2ebc8 · 1.0.8: release, will be tagged as sbcl_1_0_8 · 
    changes in sbcl-1.0.8 relative to sbcl-1.0.7:
  * enhancement: experimental macro SB-EXT:COMPARE-AND-SWAP provides
    atomic compare-and-swap operations on threaded platforms.
  * enhancement: experimental function SB-EXT:RESTRICT-COMPILER-POLICY
    allows assigning a global minimum value to optimization qualities
    (overriding proclamations and declarations).
  * enhancement: closed over variables can be stack-allocated on x86
    and x86-64.
  * performance bug fix: GETHASH and (SETF GETHASH) are once again
    non-consing.
  * optimization: slot definition lookup is now O(1). This speeds up
    eg. SLOT-VALUE and (SETF SLOT-VALUE) with variable slot names.
  * optimization: STRING-TO-OCTETS is now up to 60% faster for UTF-8.
  * optimization: ASSOC and MEMBER can now be open-coded for all
    combinations of keyword arguments when second argument is constant
    and SPEED >= SPACE. In other cases a specialized version is
    selected.
  * bug fix: using obsoleted structure instances with TYPEP and
    generic functions now signals a sensible error.
  * bug fix: threads waiting on GET-FOREGROUND can be interrupted.
    (reported by Kristoffer Kvello)
  * bug fix: backtrace construction is now more careful when making
    lisp-objects from pointers on the stack, to avoid creating bogus
    objects that can be seen by the GC.
  * bug fix: defaulting of values in contexts expecting more than 7
    variables now works on x86-64.  (reported by Christopher Laux)
  * bug fix: modifications to packages (INTERN, EXPORT, etc) are now
    thread safe.
  * bug fix: (SETF SYMBOL-PLIST) no longer allows assigning a non-list
    as the property-list of a symbol.
  * bug fix: DEFMETHOD forms with CALL-NEXT-METHOD in the method body,
    in EVAL-WHEN forms with both :COMPILE-TOPLEVEL and :LOAD-TOPLEVEL
    situations requested, are once again file-compileable.  (reported
    by Sascha Wilde)

  • sbcl_1_0_7

    d3e5c969 · 1.0.7: release, will be tagged as sbcl_1_0_7 · 
    changes in sbcl-1.0.7 relative to sbcl-1.0.6:
  * MOP improvement: support for user-defined subclasses of
    SB-MOP:SPECIALIZER has been enhanced.  The experimental interface
    function SB-PCL:MAKE-METHOD-SPECIALIZERS-FORM, called as part of
    the expansion of DEFMETHOD, is responsible for generating a form
    which creates a list of specializers when evaluated.  Additional
    functions SB-PCL:[UN]PARSE-SPECIALIZER-USING-CLASS provide
    debugging and introspective support.
  * minor incompatible change: the (unsupported) spinlock interface
    has changed: free spinlock now has the value NIL, and a held spinlock
    has the owning thread as its value.
  * enhancement: WITHOUT-INTERRUPTS now binds ALLOW-WITH-INTERRUPTS and
    WITH-LOCAL-INTERRUPTS as local macros. Refer to documentation string
    for details.
  * enhancement: name of a socket-stream is now "a socket" instead of
    "a constant string".
  * enhancement: SB-POSIX now supports lockf(). (Thanks to Zach Beane.)
  * enhancement: SB-POSIX now supports getcwd(). (Thanks to Tassilo Horn.)
  * enhancement: SB-INTROSPECT:FUNCTION-ARGLIST shows nicer argument lists
    for generic functions. (Thanks to Tobias C. Rittweiler)
  * optimization: bignum printing speed has been improved by 20-40%
    (depending on the bignum size.)
  * bug fix: WITH-MUTEX and WITH-RECURSIVE-LOCK are now interrupt safe
    on Linux.
  * bug fix: the cache used by the CLOS to store precomputed effective
    methods, slot offsets, and constant return values is now thread and
    interrupt safe.
  * bug fix: generic function dispatch function updating is now thread
    and interrupt safe (in the sense that the known issues have been
    fixed.)
  * bug fix: ADD/REMOVE-METHOD is now thread and interrupt safe.
  * bug fix: interning EQL-specializers is now thread and interrupt safe.
  * bug fix: asdf systems with dependencies to the SB-POSIX or
    SB-BSD-SOCKETS contribs can be loaded with :FORCE T.
  * bug fix: interrupt safety of applicable method computation has been
    improved.

  • sbcl_1_0_6

    6a4ea976 · 1.0.6: release, will be tagged as sbcl_1_0_6 · 
    changes in sbcl-1.0.6 relative to sbcl-1.0.5:
  * new contrib: sb-cover, an experimental code coverage tool, is included
    as a contrib module.
  * optimization: STRING-TO-OCTETS for unibyte encodings and UTF-8 is
    significantly faster.
  * optimization: calls of the form (AREF FOO (+ INDEX <constant>)) now
    produce more efficient code on x86-64 if the compiler can determine
    that (+ INDEX <constant>) does not require a bounds check and FOO
    has an element type at least 8 bits wide.
  * enhancement: a new, experimental synchronous timeout facility is
    provided. Refer to SB-SYS:WITH-DEADLINE for details.
  * enhancement: when a symbol name conflict error arises, the
    conflicting symbols are always printed with a package prefix.
    (thanks to Kevin Reid)
  * enhancement: stepping is now once again supported on the SPARC and
    MIPS platforms.  (It is also now more likely to work on CheneyGC
    builds on the PPC.)
  * enhancement: sb-sprof can now also track and report accurate call
    counts.
  * bug fixes: the treatment of non-standard subclasses of
    SB-MOP:SPECIALIZER is more correct.
  * incompatible change: PURIFY no longer copies the data from the
    dynamic space into the static and read-only spaces on platforms
    that use the generational garbage collector
  * bug fix: GETHASH, (SETF GETHASH), CLRHASH and REMHASH are now
    interrupt safe.
  * bug fix: GC race condition occasionally resulting in crashes with
    the error message "SIG_STOP_FOR_GC blocked at a bad place" has been
    fixed.
  * bug fix: &ENVIRONMENT variables in macro lambda lists can now be
    declared ignored.
  * bug fix: DEFSETF lambda lists without &ENVIRONMENT no longer cause
    a STYLE-WARNING to be signalled (regression from 1.0.4.)
  * bug fix: an asynchronous interrupt could previously leave the
    system running with GC inhibited.
  * bug fix: a DECLARE form evaluated at top-level now causes an error
    rather than silently (or verbosely) returning NIL.
  * bug fix: trying to dissassemble functions compiled at high DEBUG could
    result in a error being signalled due to source form lookup errors.
    (reported by Peter Graves)

  • sbcl_1_0_5

    of all data types, but instead use an EQL hash for types for which
    EQUAL is the same as EQL.
  * optimization: the non-inlined generic versions of AREF and (SETF AREF)
    are significantly faster.
  * optimization: new STRING-OUTPUT-STREAM implementation is much
    faster for large outputs and conses 30% less on average.
  * enhancement: XREF information is now collected for references made
    to global variables using SYMBOL-VALUE and a constant argument.
  * enhancement: SIGINT now causes a specific condition
    SB-SYS:INTERACTIVE-INTERRUPT to be signalled.

    required by the CLHS. (reported by Samium Gromoff)
  * bug fix: dead unbound variable references now signal an error.
    (reported by Marco Monteiro)
  * bug fix: / with an unused value was being deleted in safe code.
    (thanks to Marco Monteiro and Kevin Reid)
  * bug fix: number of characters that can be written onto a single
    line in a file is unlimited.
  * bug fix: some GC deadlocks caused by asynchronous interrupts have
    been fixed by inhibiting interrupts for when GC is disabled.

  * bug fix: SB-EXT:MUFFLE-CONDITIONS declarations no longer trigger a
    bogus warning in DEFMETHOD bodies. (reported by Kevin Reid)
  * bug fix: an &environment argument with the correct variable information
    is passed to macros that are expanded during byte compilation.
    (reported by Samium Gromoff)
  * bug fix: a logic error was causing the hash function for bignums to
    have excessive amounts of collisions. (reported by Faré Rideau)

    for the debugger tests) but should still be considered
    experimental until this is fixed.
  * improvement: a style-warning is signaled for CASE (etc) clauses with
    duplicate keys. (thanks to Kevin Reid)
  * improvement: macos/x86 and macos/x86-64 now use mach exception
    handlers for dealing with illegal instructions (for trapping and
    error handling) and memory protection violations (for GC).

    ea155ea4 · 1.0.4: release, will be tagged as sbcl_1_0_4 · 
    changes in sbcl-1.0.4 relative to sbcl-1.0.3:
  * new platform: experimental support for x86-64/darwin (MacOS).
  * incompatible change: the thread-safe (on most platforms) getaddrinfo
    and getnameinfo sockets functions are used instead of gethostbyaddr
    and gethostbyname, on platforms where the newer functions are available.
    As a result, the ALIASES field of HOST-ENT will always be NIL on these
    platforms.
  * change: runtimes with embedded cores (i.e. saved with :EXECUTABLE T)
    don't print the startup banner, but behave as if --noinform was passed

    variables no longer signals bogus package lock violations. (reported
    by Eric Marsden)

    such as (SINGLE-FLOAT 1.0 2.0) no longer causes a compile-time error.
    (reported by Andras Simon)
  * bug fix: >= and <= gave wrong results when used with NaNs. (Some NaN
    bugs remain on x86-64.)
  * bug fix: the #= and ## reader macros now interact reasonably with
    funcallable instances.
  * bug fix: type-checks for function arguments were compiled using the
    compiler policy settings of the wrong lexical environment (in 1.0.2
    and 1.0.3).

    823eef4d · 1.0: · 
    changes in sbcl-1.0 relative to sbcl-0.9.18:
  * improvement: experimental support for threading on FreeBSD/x86.
    (thanks to NIIMI Satoshi)
  * improvement: runtime option --dynamic-space-size can be used
    to set the size of the dynamic space reserved on startup.
  * improvement: floating point modes in effect are now saved in
    core, and restored on startup.
  * improvement: GET-INTERNAL-REAL-TIME now reports the time since
    startup, not time since first call to GET-INTERNAL-REAL-TIME.
  * improvement: SAVE-LISP-AND-DIE explicitly checks that multiple
    threads are not running after *SAVE-HOOKS* have run.
  * improvement: writes to CLOS instance slots are type-checked in code
    compiled with (SAFETY 3)
  * improvement: floating-point exception handling on FreeBSD (thanks to
    NIIMI Satoshi)
  * improvement: SB-POSIX supports time(2), utime(2) and utimes(2)

    on Linux/x86
  * improvement: added support for the Shift-JIS external format.
    (contributed by NIIMI Satoshi)
  * improvement: callbacks are supported on Linux/PPC.  (thanks to
    Joshua Ross)
  * bug fix: compiler bug triggered by a (non-standard) VALUES
    declaration in a LET* was fixed. (reported by Kaersten Poeck)
  * bug fix: file compiler no longer confuses validated and already
    dumped structurres. (reported by Kaersten Poeck)
  * bug fix: ADJUST-ARRAY :FILL-POINTER T on an array without a
    fill-pointer signals a type-error as required. (thanks to
    Lars Brinkhoff)
  * bug fix: disassemly of funcallable instances works.
  * bug fix: single stepping on PPC.
  * bug fix: fix thread-safety problems in the type system (generally
    manifesting as nonsensical errors like "STRING is a bad type specifier
    for sequences" or "The value 1 is not of type FIXNUM")
  * bug fix: version components are handled correctly in TRANSLATE-PATHNAME
    (reported by Josip Gracin)
  * bug fix: an error is signaled for attempts to displace arrays with
    incompatible element types (thanks to Mario Mommer)
  * bug fix: more correct handling of wide characters in debug info
    (bug reported by Attila Lendvai and fixed by Juho Snellman)
  * optimization: method calls with &OPTIONAL or &KEY arguments are faster
    and don't cause extra consing
  * optimization: MAP and MAP-INTO are significantly faster on vectors
    whose elements types have been declared.
  * Improvements to SB-SPROF:

    changes in sbcl-0.9.18 (1.0.beta?) relative to sbcl-0.9.17:
  * enhancement: SB-POSIX now supports cfsetispeed(3), cfsetospeed(3),
    cfgetispeed(3), cfgetospeed(3), and related constants. (thanks to
    Max-Gerd Retzlaff)
  * bug fix: two potential GC deadlocks affecting threaded builds.
  * bug fix: (TYPEP #\A '(NOT (MEMBER #\" #\{ #\:))) now correctly
    returns T (reported by Anton Kazennikov)
  * bug fix: the STORE-VALUE restart of CHECK-TYPE works correctly
    with non-variable places
  * bug fix: remove a race condition in the setting of
    funcallable-instance functions, this should make threaded CLOS
    code more stable against memory faults.
  * bug fix: corruption of specials when unbinding is interrupted by an
    asynchronous unwind (reported by Hannu Koivisto)
  * improvement: the debugger will now also display local variables that
    are only used once, for code compiled with a DEBUG optimization quality
    of 2 or higher.

  • sbcl_0_9_17

    ad92fc1a · 0.9.17: · 
    changes in sbcl-0.9.17 (0.9.99?) relative to sbcl-0.9.16:
  * feature: weak hash tables, see MAKE-HASH-TABLE documentation
  * incompatible change: External-format support for FFI calls.  The
    SB-ALIEN:C-STRING no longer implies an ASCII
    external-format. Instead the string is subject to external-format
    conversion. Additionally return values of type SB-ALIEN:C-STRING
    are by default of type (SIMPLE-ARRAY CHARACTER), not
    SIMPLE-BASE-STRING. For an alien type that behaves like the old
    SB-ALIEN:C-STRING type, use (SB-ALIEN:C-STRING :EXTERNAL-FORMAT
    :ASCII :ELEMENT-TYPE BASE-CHAR).  (thanks to Yaroslav Kavenchuk)
  * incompatible change: SB-EXT package no longer contains the
    following unused symbols: *GC-NOTIFY-AFTER*, *GC-NOTIFY-BEFORE*,
    *GC-NOTIFY-STREAM*, *ERROR-PRINT-LENGTH*, *ERROR-PRINT-LEVEL*,
    *ERROR-PRINT-LINES*
  * incompatible change: the single-stepper is no longer available
    on Alpha, Mips and Sparc platforms.
  * minor incompatible change: the direct superclasses of
    SB-MOP:FUNCALLABLE-STANDARD-OBJECT are (FUNCTION STANDARD-OBJECT),
    not (STANDARD-OBJECT FUNCTION).  This makes the
    class-precedence-lists of GENERIC-FUNCTION and
    STANDARD-GENERIC-FUNCTION comply with the requirement of ANSI
    1.4.4.5.
  * minor incompatible change: the default stream external format on
    non-unicode SBCL is no longer detected from the locale, but is always
    ISO-8859-1
  * new feature: Add a version of evaluator that uses an interpreter instead
    of the compiler. EVAL still uses the compiler by default, to switch it
    to use the interpreter, set the value of the variable
    SB-EXT:*EVALUATOR-MODE* to :INTERPRET.
  * minor incompatible change: the single-stepper REPL has been merged
    with the normal debugger (see the "Stepping" heading of the debugger help
    for more details). The debugger command STEP will no longer switch
    to the single-stepper REPL.
  * bug fix: ENOUGH-NAMESTRING on pathnames with no name and a pattern
    for a type now works.
  * bug fix: loading of default sysinit file works. (thanks to Leonid
    Slobodov)
  * bug fix: better detection of circularities in the file-compiler.
    (reported by Marco Monteiro)
  * bug fix: the CL pathname functions now work with files that have
    non-ASCII characters in their names (thanks to Yaroslav Kavenchuk)
  * bug fix: The :PTY argument for RUN-PROGRAM will now work on
    systems with Unix98 pty semantics.
  * bug fix: ASDF-INSTALL will now work with bsd tar.
  * bug fix: ASDF-INSTALL uses GNU tar on Solaris (thanks to Josip
    Gracin).
  * bug fix: timers expiring in dead threads no longer cause a
    type-error (reported by Paul "Nonny Mouse").
  * bug fix: thanks to more lightweight single-stepper instrumentation,
    code compiled with (DEBUG 3) will compile and execute significantly faster,
    and will have more accurate type-inferencing than before
  * bug fix: SLOT-VALUE optimizations are no longer done on method parameters
    whose bindings are modified
  * improvements to the win32 port (thanks to Yaroslav Kavenchuk):
    ** bug fix: arguments to RUN-PROGRAM are escaped correctly
    ** replace dummy implementations of CL:MACHINE-INSTANCE and
       CL:SOFTWARE-VERSION with proper version

    6d26ba97 · 0.9.16: · 
    changes in sbcl-0.9.16 relative to sbcl-0.9.15:
  * feature: implemented the READER-METHOD-CLASS and
    WRITER-METHOD-CLASS portion of the Class Initialization Protocol
    as specified by AMOP.
  * incompatible change: variable SB-EXT:*USE-IMPLEMENTATION-TYPES*
    no longer exists.
  * optimization: faster LOGCOUNT implementation on x86 and x86-64
    (thanks to Lutz Euler)
  * optimization: hashing of general arrays and vectors has been
    improved. (reported by Any Fingerhut)
  * enhancement: SB-INTROSPECT is now able to find definitions of
    profiled functions. (thanks to Troels Henriksen)
  * enhancement: compiler-macro expansion applies now to FUNCALL forms
    as well, allowing compiler-macros for SETF-functions to expand.
  * enhancement: step-instrumentation no longer wraps known
    single-value functions with multiple-value context, allowing
    better type inference.
  * fixed bug #337: use of MAKE-METHOD in method combination now works
    even in the presence of user-defined method classes.  (reported by
    Bruno Haible and Pascal Costanza)
  * fixed bug #339(c): if there are applicable methods not part of any
    long-form method-combination group, call INVALID-METHOD-ERROR.
    (reported by Bruno Haible)
  * fixed bug #361: the :FUNCTION initarg in the protocol for
    initialization of methods can now be used to override
    internally-produced optimized functions.  (reported by Bruno
    Haible)
  * bug fix: extensions of MAKE-METHOD-LAMBDA which wrap the
    system-provided lambda expression no longer cause warnings about
    unbound #:|pv-table| symbols.
  * bug fix: improved the handling of type declarations and the
    detection of violations for keyword arguments with non-constant
    defaults.
  * bug fix: potentially erronous calls to PATHNAME and
    MERGE-PATHNAMES were being flushed in some cases.
    (reported by Richard Kreuter)
  * bug fix: compiled calls to TYPEP were mishandling obsolete
    instances.  (reported by James Bielman and Attila Lendvai)
  * bug fix: format strings with ~> without matching ~< no longer
    trigger an AVER, but signal an understandable error instead.
    (reported by Antonio Martinez)
  * bug fix: specifying an output-file without a pathname-type for
    COMPILE-FILE or COMPILE-FILE-PATHNAME resulted in using the type
    of input-file instead of "fasl". (reported by Robert Dodier)
  * bug fix: compiler-macro lambda-list parsing of FUNCALL forms.
    (reported by James Y Knight).
  * bug fix: compiler-macros-function did not consider the environment
    argument for shadowing by local functions.
  * bug fix: compiler-macros expansion was inhibited by local INLINE
    declarations.
  * bug fix: inline expansions of known functions were subject to
    step-instrumentation in high debug policies, leading to problems
    with type-inference.
  * bug fix: compiler failed to differentiate between different CONS
    types in some cases.
  * bug fix: fixed input, output and error redirection in RUN-PROGRAM
    for win32. (thanks to Mike Thomas and Yaroslav Kavenchuk)
  * bug fix: #368: incorrect use of expressed vs. upgraded array
    element type.
  * bug fix: #306a: more precise unions of array types.
  * thread-safety improvements:
    ** CONDITION-WAIT could return early on Linux, if the thread was
       interrupted and subsequently continued with SIGCONT.
    ** STABLE-SORT and ADJUST-ARRAY were not reentrant.

    02e900a3 · 0.9.14: · 
    changes in sbcl-0.9.14 relative to sbcl-0.9.13:
  * feature: thread support on Solaris/x86, and experimental thread support
    on OS X/x86.
  * feature: SBCL now tries to signal a STORAGE-CONDITION when running out
    of heap.
  * feature: SBCL now provides USE-VALUE and STORE-VALUE restarts in the
    default method for SLOT-UNBOUND.
  * 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).
  * minor incompatible change: the :SB-LDB feature is now enabled by
    default, and DISABLE-DEBUGGER and ENABLE-DEBUGGER also affect
    the low-level debugger.
  * enchancement: RUN-PROGRAM is now able to extract the file-descriptor
    from SYNONYM-STREAM and TWO-WAY-STREAM provided they can be decomposed
    down to an SB-SYS:FD-STREAM, allowing direct communication in
    more cases. Temporary files and pipes are still used as a fallback
    strategy.
  * thread-safety: DECODE-UNIVERSAL-TIME & GET-DECODED-TIME depended
    on the non-reentrant C functions localtime(3) and gmtime(3).
  * bug fix: global optimization policy was not visible in LOCALLY and
    MACROLET forms.
  * bug fix: class objects can be used as specializers in methods.
    (reported by Pascal Costanza)
  * bug fix: native unparsing of pathnames with :DIRECTORY NIL failed
    with a type error. (reported by blitz_ on #lisp)
  * bug fix: unparsing logical pathnames with :NAME :WILD :TYPE NIL
    failed with a type error.  (reported by Pascal Bourguignon)
  * bug fix: merging pathnames against defaults with :DIRECTORY
    starting with '(:RELATIVE :BACK) should preserve the :BACK.
    (reported by James Y Knight)
  * bug fix: saving large (>2GB) cores on x86-64 now works
  * bug fix: a x86-64 backend bug when compiling (setf aref) with a
    constant index and a (simple-array (signed-byte 32)) array
  * bug fix: NAME-CHAR on an invalid symbol no longer signals an
    error (patch by Robert J. Macomber)
  * feature: TIME now displays the amount of run-time spent in GC
  * bug fix: The debugger now does a better job of respecting
    (PUSH '(*PRINT-CIRCLE* . T) SB-DEBUG:*DEBUG-PRINT-VARIABLE-ALIST*)
    when printing SB-DEBUG:*DEBUG-CONDITION*. (This is a debugger-only
    workaround for bug 403.)
  * bug fix: floating point exception handling now works on FreeBSD
    (thanks to NIIMI Satoshi)
  * fixed some bugs revealed by Paul Dietz' test suite:
    ** MISC.641: LET-conversion were not supposed to work in late
       compilation stages.
  * improvements to the Win32/x86 port:
    ** GET-INTERNAL-RUN-TIME implemented, thanks to Frank Buss.
    ** improved SB-BSD-SOCKETS support, thanks to Timothy Ritchey.

    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

    functions

  • sbcl_0_9_12

    72db4527 · 0.9.12: · 
    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)

    ** 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.
