changes in sbcl-1.0.43 relative to sbcl-1.0.42:
  * incompatible change: FD-STREAMS no longer participate in the serve-event
    event-loop by default. (lp#316072)
    ** In addition to streams created by explicit calls to MAKE-FD-STREAM this
       affects streams from CL:OPEN.
    ** Streams from SOCKET-MAKE-STREAM still participate in serve-event by
       default, but this is liable to change: applications needing serve-event
       for socket streams should explicitly request it using :SERVE-EVENTS T
       in the call.
  * enhancement: SB-EXT:WORD type is provided for use with SB-EXT:ATOMIC-INCF
    &co.

    (not in launchpad, reported by sykopomp in #lispgames)
  * bug fix: package-locks failed to protect against compile-time effects of
    DEFUN when the symbol previously had a macro definition. (lp#576637)
  * bug fix: spurious ignore warnings even given (DECLARE IGNORE) in methods
    when parameter bindings mutated.  (reported by Faré Rideau; lp #611361)
  * bug fix: workaround for compiler hang in ORDER-UVL-SETS (lp#308914)
  * bug fix: evaluation in debugger REPL works using the global context when
    in frames that do not have sufficient debug information.

changes in sbcl-1.0.42 relative to sbcl-1.0.41
  * build changes
    ** Cross-compilation host is now specified to make.sh using
       command-line argument --xc-host=<command> instead of a positional
       argument. (thanks to Daniel Herring)
    ** Install location can be specified to make.sh using command-line

    argument is a floating point zero. (lp#571581, thanks to Roman Marynchak)
  * bug fix: DEFTYPE signals an error for non-list lambda-lists.
    (lp#576594, thanks to Roman Marynchak)
  * bug fix: make ASDF-INSTALL compatible with the now-included ASDF2.
    (lp#612998, reported by Phil Hargett; patch from Jim Wise)

changes in sbcl-1.0.41 relative to sbcl-1.0.40:
  * optimization: validity of observed keyword initargs to MAKE-INSTANCE is
    cached, leading to many fewer expensive calls to
    COMPUTE-APPLICABLE-METHODS.
  * optimization: in the (unoptimized) general method for MAKE-INSTANCE on a
    CLASS argument, search for and call an appropriate optimized ctor function
    if it exists.
  * bug fix: WRITE always returns the correct value.

Debian release 1:1.0.40.0-2

Debian release 1:1.0.39.0-2

changes in sbcl-1.0.40 relative to sbcl-1.0.39:
  * bug fix: readdir now works on :inode64 darwin builds (lp#592897)
  * bug fix: Name conflicts between symbols passed as arguments to a single
    call to IMPORT no longer add multiple symbols with the same name to the
    package (detectable via DO-SYMBOLS).
  * bug fix: support building without the dlshim on darwin x86 and x86-64
    (lp#533470).
  * bug fix: TRACE :ENCAPSULATE NIL now works on ppc/linux.

Debian release 1:1.0.34.0-1.1

changes in sbcl-1.0.39 relative to sbcl-1.0.38:
  * bug fix: Backtrace from undefined function on x86 and x86-64 now show
    the calling frame.
  * bug fix: linkage-table entries on PPC now no longer overflow their
    space allocation (potentially causing crashes if they are written out
    of order).
  * bug fix: Scrub control stack after scavenging in gencgc on non-x86oid
    platforms, preventing the GC from seeing stale pointers on the control
    stack in subsequent GCs (which would, and does, break invariants).
  * bug fix: 32-bit unicode external formats now work on big-endian systems.
  * bug fix: Literal characters with code points greater than about 32767
    now work on PPC UNICODE builds.
  * bug fix: Any noise left by SSE operations (sqrt and conversions) in the
    high order bits are explicitly cleared out. In some contrived situations,
    this could lead to wrong results in mixed real/complex float arithmetic.
  * bug fix: Fix function/macro redefinition warnings when building with
    clisp.  (lp#576787, thanks to Josh Elsasser)
  * new platform: experimental support for ppc/openbsd (thanks to Josh
    Elsasser).

changes in sbcl-1.0.38 relative to sbcl-1.0.37:
  * incompatible change: Thread names are now restricted to SIMPLE-STRINGs
    like for any other thread-related datastructure, MUTEX, etc. (lp#547095)
  * deprecation: the SB-QUEUE contrib was merged into the SB-CONCURRENCY
    contrib module. New code should depend on SB-CONCURRENCY, not SB-QUEUE.
  * deprecation: SB-THEAD:GET-MUTEX was deprecated in favor of
    SB-THREAD:GRAB-MUTEX.
  * new contributed module: SB-CONCURRENCY is a new contrib; it's supposed to
    contain additional data structures and tools for concurrent programming;
    at the moment it contains a lock-free queue, and a lock-free mailbox
    implementation.
  * new feature: added SB-THREAD:GRAB-MUTEX; it's like the now deprecated
    GET-MUTEX but takes &key rather than &optional parameters.  Also added
    :TIMEOUT argument to GRAB-MUTEX on non-sb-lutex platforms like Linux and
    BSD.
  * new feature: added SB-THREAD:TRY-SEMAPHORE, a non-blocking variant of
    SB-THREAD:WAIT-ON-SEMAPHORE.
  * new feature: SB-EXT:ATOMIC-DECF has been added as a companion to
    SB-EXT:ATOMIC-INCF.
  * new feature: a CANCEL-DEADLINE is associated with DEADLINE-TIMEOUT
    conditions to defer the deadline for forever.
  * enhancement: *STANDARD-OUTPUT*, *STANDARD-INPUT*, and *ERROR-OUTPUT* are
    now bivalent.
  * enhancement: errors from NO-APPLICABLE-METHOD and
    NO-PRIMARY-METHOD now have a RETRY restart available to retry the
    generic function call.
  * enhancement: SB-BSD-SOCKET improvements
    ** sockets and socket streams now have a more informative printed
       representation based on the corresponding SOCKET-NAME and
       SOCKET-PEERNAME.
    ** SOCKET-MAKE-STREAM once more supports the :AUTO-CLOSE option.
       (lp#540413)
    ** SOCKET-CLOSE now accepts :ABORT argument, which is passed on to
       CL:CLOSE when appropriate, and no longer disassociates the stream
       from the socket if close failed. (lp#543951)
  * improvements to the instrumenting profiler
    ** new feature: report per-function GC overhead. (thanks to John Fremlin)
    ** optimization: counters no longer use locks for the overflow mode.
    ** bug fix: whenever a profiling counter wrapped into overflow mode, it
       incurred an off-by-one miscount.
  * enhancement: improved MAKE-HASH-TABLE documentation (lp#543473)
  * enhancement: improved DEFMETHOD pretty-printing.
  * enhancement: perform range reduction when arguments are too large for
    x87's transcendentals (instead of returning 0). (lp#327192)
  * enhancement: eliminate some spurious TYPE-WARNINGs. Should help with
    some of CL-PPCRE's macros. (lp#570079)
  * enhancement: our machine code is slightly less hostile to valgrind on
    x86-64.
  * enhancement: up-to-date versions of NetBSD-current are supported.  (Thanks
    to Robert Swindells and Aleksej Saushev)
  * bug fix: correct restart text for the continuable error in MAKE-PACKAGE.
  * bug fix: a rare case of startup-time page table corruption.
  * bug fix: a semaphore with multiple waiters and some of them unwinding due
    to timeouts could be left in an inconsistent state.
  * bug fix: fix typo in "Reporting Bugs" section of the manual (lp#520366)
  * bug fix: misoptimization of multiplication by one in
    (SB-C::FLOAT-ACCURACY 0) policies.
  * bug fix: miscounts in SB-PROFILE.
  * bug fix: Fix lost wakeup bug between SB-THREAD:CONDITION-WAIT and
    CONDITION-NOTIFY on Linux. See threads "lost wakeup in condition-wait /
    condition-notify" (Feb 2010) and "Condition-Wait, Deadline handler, waking
    up itself" (March 2010) for further details.
  * bug fix: allow forward FIND and POSITION on lists to elide checking :END
    against length of the list if the element is found before the specified
    END is reached. (thanks to Alec Berryman, lp#554385)
  * bug fix: errors signalled during package graph modification no longer
    block FIND-SYMBOL and FIND-PACKAGE in other threads. (lp#511072)
  * bug fix: SB-POSIX build was broken when SBCL was compiled without the
    :SB-DOC feature. (lp#552564)

  * bug fix: GCD always returns positive values. (lp#413680)
  * bug fix: Converting division to multiplication by reciprocal handles
    denormals.
  * bug fix: We were too eager in eliding range reduction tests on x87.
    The maximal magnitude is 2^63, not 2^64.
  * bug fix: Transforms for TRUNCATE don't die when the result is completely
    ignored anymore.
  * bug fix: Maybe restore buildability on Alpha.
  * bug fix: READ-BYTE isn't inline anymore, fixing weird streams failures.
    (lp#569404)
  * bug fix: RANDOM-STATE can be printed readably again.
  * bug fix: Unreadable objects were sometimes printed like #<\nFoo>.
  * bug fix: Using EQL with non-constant values of constant type (e.g. EQL
    types) could result in type mismatches during compilation.

changes in sbcl-1.0.37 relative to sbcl-1.0.36:
  * enhancement: Backtrace from THROW to uncaught tag on x86oids now shows
    stack frame thrown from.

    translations from SYS:SITE;<HOST>.TRANSLATIONS.NEWEST (thanks to Michael
    Weber)
  * optimization: SLOT-VALUE and (SETF SLOT-VALUE) take advantage of
    constraint propgation, allowing better compilation eg. when used to
    access structures with WITH-SLOTS. (lp#520366)
  * optimization: the compiler is now more aware of the type of the underlying
    storage vector for multidimensional simple arrays resulting in better code
    for accessing such arrays.
  * optimization: passing NIL as the environment argument to TYPEP no longer
    inhibits optimizing it. (lp#309788)
  * optimization: more efficient register usage when handling single-float
    arguments on x86-64. (thanks to Lutz Euler)
  * optimization: ADJUST-ARRAY and STABLE-SORT on vectors no longer use
    pre-allocated temporary vectors. (lp#496249)

    WITH-SLOTS usages during compilation.
  * bug fix: SB-C::CLASS-INFO now prints correctly. (lp#514762)
  * enhancement: Can now build with ud2 instead of int3 as trap instruction on
    all x86oid platforms with :UD2-BREAKPOINTS target feature.
  * bug fix: Breakpoints now work when using ud2 instead of int3 as trap
    instruction (tested on x86oid linux with ud2-breakpoints).
  * bug fix: slam.sh now works on win32.
  * bug fix: better differences of numeric types. (lp#309124)
  * bug fix: arrays declared intersection and union types can have their
    upgraded element type derived. (lp#316078)
  * bug fix: SB-SPROF allocation profiling for all threads failed to profile
    threads started during profiling. (lp#472499)
  * bug fix: SB-INTROSPECT test failure when building without SB-EVAL feature.
    (lp#535658)
  * bug fix: SB-CLTL2:DECLARATION-INFORMATION did not take
    SB-EXT:RESTRICT-COMPILER-POLICY into account. (lp#313337)

    due to it, so that handlers can run.
  * bug fix: reparsing undefined types if they have become defined since
    parsing. (lp#309128)
  * bug fix: missing &REST type in a proclamation for a function with both
    &REST and &KEY in lambda-list caused miscompilation (lp#458354)
  * bug fix: WHO-CALLS information for source-transformed and compiler-macro
    expanded calls (lp#542174)
  * bug fix: more accurate WHO-MACROEXPANDS information; point into rather
    than just at toplevel form.

changes in sbcl-1.0.36 relative to sbcl-1.0.35:
  * new feature: SB-EXT:TYPEXPAND-1, SB-EXT:TYPEXPAND, and
    SB-EXT:TYPEXPAND-ALL behave exactly like their MACROEXPAND counterparts
    but work on type specifiers.
  * new feature: SB-EXT:DEFINED-TYPE-NAME-P returns whether a symbol is known
    to name a type specifier.
  * new feature: SB-EXT:VALID-TYPE-SPECIFIER-P returns whether a given type
    specifier is valid where "valid" basically means "would be accepted as
    second argument of TYPEP".
  * new feature: SB-INTROSPECT:FUNCTION-TYPE takes a function-designator and
    returns the function's declared, or derived FTYPE.
  * new feature: SB-POSIX now supports accessing the d_ino member of
    dirent structures.  (Thanks to Philipp Marek and Pierre THEIRRY)
  * new feature: The function SB-EXT:SEED-RANDOM-STATE has been added to
    provide for seeding a RANDOM-STATE object with user-provided data or
    from the operating system's PRNG.  Also, (MAKE-RANDOM-STATE T) will
    attempt to initialize the returned state from the operating system's
    PRNG where possible.  (Thanks to Fare Rideau; launchpad bug lp#310116)
  * bug fix: Fix SB-SIMPLE-STREAMS:READ-VECTOR to correctly set the
    FILE-POSITION of the stream being read from.  (launchpad bug lp#491087)
  * bug fix: Fix grammar and style issues for the docstrings of
    printer-related variables and functions.  (Thanks to mon_key; launchpad
    bug lp#518696)
  * bug fix: Fix compilation on chenygc platforms. Thanks to Larry Valkama and
    Bruce O'Neel.

    future. (lp#512914)
  * bug fix: A deadline handler was run without interrupts enabled for a
    deadline signaled within SB-THREAD:CONDITION-WAIT. That could result
    in infinitely spinning, non-killable threads.
