+ * new feature: SB-INTROSPECT:DEFTYPE-LAMBDA-LIST allows retrieval of
+ DEFTYPE lambda lists. (thanks to Tobias Rittweiler)
+ * improvement: reading from a TWO-WAY-STREAM does not touch the output
+ stream anymore making it thread safe to have a concurrent reader and
+ a writer, for instance, in a pipe.
+ * improvement: GET-SETF-EXPANDER avoids adding bindings for constant
+ arguments, making compiler-macros for SETF-functions able to inspect
+ their constant arguments.

+ designator, and returns T instead of the function. (thanks to
+ Tobias Rittweiler)
+ * bug fix: direct superclasses of STANDARD-CLASS and
+ FUNCALLABLE-STANDARD-CLASS now default to STANDARD-OBJECT and
+ FUNCALLABLE-STANDARD-OBJECT as required by AMOP.
+ * bug fix: compiling a call to SLOT-VALUE with a constant slot-name
+ when no class with the named slot yet exists no longer causes a
+ compile-time style-warning.

+ in safe code. (reported by Didier Verna)
+ * bug fix: #430; nested structure constructors can stack allocate.
+ * bug fix: on some 64-bit platforms dynamic space size was truncated
+ to #xffff0000 bytes. (reported by Benjamin Lambert)
+ * bug fix: setting *READ-SUPPRESS* to T no longer renders the default
+ REPL unusable. (reported by Daniel Herring)
+ * bug fix: return values of READ-SEQUENCE did not take :START into
+ account on file streams, regressions since 1.0.12.22. (reported by
+ Thomas Russ, patch by Paul Khuong)
+ * bug fix: using SET or (SETF SYMBOL-VALUE) to change the value of a
+ method specializer used to confuse permuation vector optimization.
+ * bug fix: system inserted bogus implicit type declarations for local
+ special variables in DEFMETHOD bodies.
+ * bug fix: #354; duplicated frames in backtraces due to
+ non-tail-call-optimized XEPs to functions with return type NIL
+ have been elimited.
+ * bug fix: #357; MAKE-INSTANCE/SHARED-INITIALIZE now
+ initializes structure object slots according to DEFSTRUCT initforms,
+ and DEFSTRUCT forms :INCLUDEind structure classes defined using

+ types.
+ * bug fix: address-spaces overlapped on OpenBSD. (thanks to Josh
+ Elsasser)
+ * bug fix: Mac OS X binaries should now be portable between Leopard
+ and Tiger.
+
+changes in sbcl-1.0.23 relative to 1.0.22:
+ * enhancement: when disassembling method functions, disassembly
+ for the associated fast function is also produced.
+ * enhancement: system stores DEFTYPE lambda-lists, so DESCRIBE can

+
+changes in sbcl-1.0.22 relative to 1.0.21:
+ * minor incompatible change: LOAD-SHARED-OBJECT no longer by default looks

+ * minor incompatible change: --disable-debugger toplevel option now takes
+ effect before processing of initialization files and --eval or --load
+ options.
+ * new feature: new commandline argument: --script, which supports
+ shebang lines. See documentation for details. (based on work by
+ Kevin Reid)
+ * new feature: SAVE-LISP-AND-DIE can save current values of
+ --dynamic-space-size and --control-stack-size in the executable core,
+ causing it to skip normal runtime option processing. See documentation
+ for details. (thanks to Zach Beane)
+ * enhancement: inoccous calls to EVAL or generic functions dispatching
+ on subclasses of eg. STREAM no longer cause compiler notes to appear.
+ * enhancement: the system no longer resignals errors from --load and
+ --eval toplevel arguments as SIMPLE-ERRORS, which caused restarts
+ associated with the original error to be lost. (thanks to Ariel
+ Badichi)
+ * enhancement: :DONT-SAVE keyword argument has been added to
+ LOAD-SHARED-OBJECT for controlling interaction with
+ SAVE-LISP-AND-DIE, and UNLOAD-SHARED-OBJECT can be used to undo
+ the effects of an earlier LOAD-SHARED-OBJECT call.
+ * bug fix: ADJUST-ARRAY on multidimensional arrays used bogusly give
+ them a fill pointer unless :DISPLACED-TO or :INITIAL-CONTENTS were
+ provided. (reported by Cedric St-Jean)
+ * bug fix: circularity handling in the reader did not treat raw
+ structure slots correctly. (reported by Cedric St-Jean)

+ references at toplevel, and LOAD of the resulting fasl did
+ not signal an error.
+ * bug fix: functions with non-required arguments used to end up with
+ (SB-C::&OPTIONAL-DISPATCH ...) as their name.
+ * bug fix: redefining a function with non-required arguments didn't
+ update the system's knowledge about its call signature properly.
+ * bug fix: fixed #431; incompatible alien record type redefinitions
+ are detected and handled. (reported by Neil Haven)
+ * bug fix: using RESTRICT-COMPILER-POLICY with DEBUG 3 could cause
+ PROGV miscompilation. (reported by Matthias Benkard, patch by Juho
+ Snellman)

+ safe.
+ * bug fix: SB-THREAD:CONDITION-WAIT doesn't allow waits on mutexes
+ owned by other threads anymore.
+ * bug fix: FIND on lists called KEY outside the specified
+ subsequence. (reported by budden)

+ given mixed integer and double-float arguments, leading to better
+ precision. (reported by Bob Felts)
+ * bug fix: LOG with base zero returned values of inconsistent type.
+
+changes in sbcl-1.0.20 relative to 1.0.19:

+ argument, and one or more &KEY arguments at the call site.
+ * bug fix: STYLE-WARNINGs for functions with both &OPTIONAL and &KEY

+
+changes in sbcl-1.0.19 relative to 1.0.18:
+ * new feature: user-customizable variable SB-EXT:*MUFFLED-WARNINGS*;

+ * optimization: stack allocation is slightly more efficient on x86
+ and x86-64.
+ * bug fix: DEFSTRUCT forms with user-specified :CONSTRUCTOR options,

+ ** interval arithmetic during type derivation used inexact integer
+ to single-float coercions.
+ ** arithmetic operations involving large integers and single
+ floats give the same results in compiled and interpreted code.
+ ** deriving the result type of COERCE no longer signals an error
+ if the derived type of the second argument is a MEMBER type
+ containing invalid type specifiers.
+ ** ADJOIN with constant NIL as second argument works correctly.
+ ** FUNCTION-KEYWORDS was called SB-PCL::FUNCTION-KEYWORD-PARAMETERS.
+
+changes in sbcl-1.0.18 relative to 1.0.17:
+ * minor incompatible change: SB-SPROF:WITH-PROFILING now by default
+ profiles only the current thread.
+ * minor incompatible change: changes to SYMBOL-VALUE of constants
+ defined with DEFCONSTANT now signal an error.
+ * enhancement: SB-SPROF now has support for wallclock profiling,
+ and is also able to profile specific threads. REPORT output
+ has also additional sorting options.

+ to Michael Weber)
+ * optimization: structure allocation has been improved
+ ** constructors created by non-toplevel DEFSTRUCTs are ~40% faster.
+ ** out of line constructors are ~10% faster.
+ ** inline constructors are ~15% faster.
+ ** inline constructors are capable of dynamic extent allocation
+ (generally on x86 and x86-64, in some cases on other platforms
+ as well.)
+ * optimization: simple uses of HANDLER-CASE and HANDLER-BIND no
+ longer cons.
+ * optimization: file compiler is now able to coalesce non-circular
+ lists, non-base strings, and bit-vectors. Additionally, constants
+ are never referenced through SYMBOL-VALUE at runtime.
+ * optimization: code defining methods on PRINT-OBJECT (and other
+ generic functions in the COMMON-LISP package) now loads faster.

+ (thanks to Travis Cross)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** NIL is a valid function name (regression at 1.0.13.38)
+ ** FILL on lists was missing its return value (regression at 1.0.12.27)
+ ** STRING-TRIM, STRING-LEFT-TRIM, and STRING-RIGHT-TRIM did not respect
+ fill pointers properly (regression at 1.0.12.23)
+ ** STRING-TRIM, STRING-LEFT-TRIM, and STRING-RIGHT-TRIM did not respect
+ displacement indices properly (regression at 1.0.12.23)
+
+changes in sbcl-1.0.17 relative to 1.0.16:
+ * temporary regression: user code can no longer allocate closure
+ variable storage on stack, due to bug 419 without explicitly
+ requesting it. Please consult sbcl-devel for advice if you need to
+ use this feature in the meanwhile.
+ * new feature: runtime argument --control-stack-size can be used to
+ adjust thread default control stack size.

+ bodies no longer cause a WARNING to be signalled. (reported by
+ Vincent Arkesteijn)

+ SBCL-specific optimize qualities.
+
+changes in sbcl-1.0.13 relative to sbcl-1.0.12:
+ * minor incompatible change: RUN-PROGRAM now uses execvp(3) to find
+ an executable in the search path, and does so in the child
+ process's PATH. The function FIND-EXECUTABLE-IN-SEARCH-PATH has
+ been removed; it can be found in the CVS history, for somebody who
+ needs that search behavior (see the manual).
+ * minor incompatible change: compiler policy re. weakening type
+ checks has changed: now type checks are weakened only if SAFETY < 2
+ and SAFETY < SPEED.
+ * SB-EXT:NATIVE-NAMESTRING takes a new keyword AS-FILE, forcing
+ unparsing of directory pathnames as files. Analogously,
+ SB-EXT:PARSE-NATIVE-NAMESTRING takes an AS-DIRECTORY, forcing a
+ filename to parse into a directory pathname.
+ * enhancement: implicit generic function creation now signals a
+ specific style-warning IMPLICIT-GENERIC-FUNCTION-WARNING, which
+ users can bind handlers for and muffle around calls to LOAD.
+ * enhancement: RUN-PROGRAM allows unicode arguments and environments
+ to be used (using the default stream external format), and allows
+ non-simple strings to be used. (thanks to Harald Hanche-Olsen)
+ * optimization: COPY-SEQ, FILL, and SUBSEQ are 30-80% faster for
+ strings and vectors whose element-type or simplicity is not fully
+ known at compile-time.
+ * optimization: STRING-TRIM and related functions no longer allocate
+ a new string when no trimming needs to be performed. These functions
+ are also faster than before when the input string has been declared
+ as a simple-string.
+ * optimization: READ-SEQUENCE on simple-strings is up to 80% faster.
+ * optimization: READ-LINE is significantly faster for files containing
+ long lines.
+ * optimization: non-open coded uses of character comparison operators
+ (e.g. char=) no longer cons when called with more than one parameter
+ on platforms supporting dynamic-extent allocation.
+ * bug fix: READ-SEQUENCE on composite stream wrapping a Gray stream
+ with STREAM-ELEMENT-TYPE (UNSIGNED-BYTE 8) signalled an error.
+ * bug fix: COPY-SEQ on lists did not signal a type-error on improper
+ lists in safe code.
+ * bug fix: some sequence functions elided bounds checking when
+ SPEED > SAFETY.
+ * bug fix: too liberal weakening of union-type checks when SPEED >
+ SAFETY.
+ * bug fix: more bogus fixnum declarations in ROOM implementation
+ have been fixed.
+
+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.
+
+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.
+
+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)
+
+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)
+
+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)
+
+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-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.
+
+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)
+
+changes in sbcl-1.0.5 relative to sbcl-1.0.4:
+ * incompatible change: removed writer methods for host-ent-name,
+ host-ent-addresses -- changing the values did not update the DNS
+ information anyway.
+ * minor incompatible change: changed experimental JOIN-THREAD interface
+ * documentation: the manual now lists reader and writer methods
+ in class slot documentation sections. (thanks to Richard M Kreuter)
+ * documentation: unwinding from asyncronous events has been
+ documented as unsafe.
+ * documentation: SB-SYS:WITHOUT-GCING has been documented as unsafe
+ in multithreaded application code.
+ * optimization: GET-INTERNAL-REAL-TIME has been optimized on POSIX
+ platforms. (thanks to James Anderson for the optimization hint)

+ variants no longer cons.
+ * optimization: Direct calls to CHAR-{EQUAL,LESSP,GREATERP} and
+ their NOT- variants no longer cons.
+ * optimization: EQUAL hash tables no longer use SXHASH for objects
+ 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.

+ ANSI requires it to return NIL.
+ * bug fix: ADJUST-ARRAY is now interrupt-safe.
+ * bug fix: adding and removing fd-handlers is now interrupt-safe.
+ * bug fix: inlined calls to C now ensure 16byte stack alignment on
+ x86/Darwin.

+ been fixed. (reported by James Anderson)
+ * bug fix: incorrect ROOM reporting on x86-64 has been fixed.
+ (thanks to Lutz Euler)

+ specifier no longer causes infinite recursion.
+ * 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)
+ * bug fix: modifying the contents of an array could change the return
+ value of SXHASH on that array, which is only allowed for strings
+ and bit vectors. (bug introduced in 0.9.16)
+ * improvement: the x86-64/darwin port now passes all tests (except
+ 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

+
+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
+ as a command line argument. (thanks to Kevin Reid)
+ * new experimental feature: added JOIN-THREAD (by NIIMI Satoshi)

+ 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)

+ by the spec (thanks to Eric Marsden)
+ * bug fix: fixed GC safety issues when foreign functions are called with

+ backtraces (reported by Edi Weitz, regression in 1.0.2)
+
+changes in sbcl-1.0.3 relative to sbcl-1.0.2:
+ * new platform: NetBSD/PPC. (thanks to Aymeric Vincent)
+ * optimization: calls of the form (AREF FOO (+ INDEX <constant>)) now
+ produce more efficient code on the x86 if the compiler can determine

+ be used to provide an implementation for FILE-POSITION on Gray streams
+ (thanks to Eric Marsden)
+ * new feature: add syslog, openlog and closelog support to SB-POSIX
+ (thanks to Richard Kreuter)
+ * optimization: the function call overhead in code compiled with
+ a high DEBUG optimization setting is significantly
+ * bug fix: an error is signaled for attempts to use READ-SEQUENCE
+ for a (SIGNED-BYTE 8) stream and (UNSIGNED-BYTE 8) vector, or vice versa.
+ (thanks to Tony Martinez)
+ * bug fix: the initforms for DEFMETHOD &AUX parameters are only

+ compiled with (< SPACE 3). This information is available through the
+ sb-introspect contrib.
+ * new feature: users may subclass SEQUENCE, and have instances of

+ a number of methods are defined. (This feature is experimental
+ and the interface subject to change based on feedback from SBCL
+ users and the general community)
+ * improvement: sb-sprof traces call stacks to an arbitrary depth on

changes in sbcl-0.9.18 (1.0.beta?) relative to sbcl-0.9.17:
* enhancement: SB-POSIX now supports cfsetispeed(3), cfsetospeed(3),
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-STEAMS provided they can be decomposed
+ 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.
