+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)
+ * 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.
+
+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 assining 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.

+ 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-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)

+ (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)
+ * optimization: REPLACE, SUBSEQ, and COPY-SEQ are now optimized in
+ more cases.
+ * optimization: STRING-{EQUAL,LESSP,GREATER-P} and their NOT-
+ 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.
+ * bug fix: FILE-POSITION used to signal an error in some cases where
+ 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)

+ (reported by Marco Monteiro)
+ * bug fix: / with an unused value was being deleted in safe code.
+ (thanks to Marco Monteiro and Kevin Reid)

+ GETHASH), CLRHASH and REMHASH have been fixed.
+ * bug fix: binding *BREAK-ON-SIGNALS* to a value that is not a type
+ 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

+ error handling) and memory protection violations (for GC).
+
+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)
+ * optimization: code using alien values with undeclared types is much faster.
+ * optimization: the compiler is now able to open code SEARCH in more cases.
+ * optimization: more compact typechecks on x86-64 (thanks to Lutz Euler)
+ * bug fix: using standardized COMMON-LISP special variables as loop
+ variables no longer signals bogus package lock violations. (reported
+ by Eric Marsden)
+ * bug fix: declaring local loop variables to be of a range-limited type
+ 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).
+ * bug fix: SHADOW accepts characters as string designators, as required
+ by the spec (thanks to Eric Marsden)
+ * bug fix: fixed GC safety issues when foreign functions are called with
+ non-base strings as arguments
+ * bug fix: more consistent error output for fatal-compiler-warnings, like
+ reader errors
+ * bug fix: functions with proper names were showing up as NIL in
+ 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
+ that (+ INDEX <constant>) does not require a bounds check and FOO
+ has an element type at least 8 bits wide.
+ * bug fix: references to undefined variables are handled the same way
+ in toplevel forms as in the normal compiler
+ * bug fix: the build scripts again work with non-bash /bin/sh (thanks
+ to Magnus Henoch)
+ * bug fix: use "gtar" as the asdf-install *TAR-PROGRAM* on NetBSD
+ (thanks to Jon Buller)

+ M Kreuter)
+
+changes in sbcl-1.0.2 relative to sbcl-1.0.1:

+ 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
+ evaluated once (reported by Kevin Reid)
+ * bug fix: the :SHOW-PROGRESS keyword parameter to SB-SPROF:WITH-PROFILING
+ works again (thanks to Kilian Sprotte)
+ * bug fix: an error is signaled for tagbodies with duplicate tags
+ (thanks to Stephen Wilson)

+ * bug fix: SBCL works on Linux/ppc systems with a kernel configured to use
+ 65k pages (thanks to David Woodhouse)
+ * bug fix: fix SB-POSIX dirent and socket on NetBSD (thanks to Richard Kreuter)
+
+changes in sbcl-1.0.1 relative to sbcl-1.0:
+ * new platform: FreeBSD/x86-64, including support for threading.
+ * new feature: the compiler stores cross-referencing information
+ abount function calls (who-calls), macroexpansion (who-macroexpands)
+ and special variables (who-binds, who-sets, who-references) for code
+ compiled with (< SPACE 3). This information is available through the
+ sb-introspect contrib.
+ * new feature: users may subclass SEQUENCE, and have instances of
+ these classes interoperate with standard Common Lisp functions if
+ 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
+ x86/x86-64, rather than the previous fixed depth of 8
+ * improvement: another pthread back-end of mutex "pthread-futex".
+ * bug fix: non-ascii command-line arguments are processed correctly

+ * bug fix: non-required arguments were not passed correctly when a method
+ defined using DEFMETHOD was called from a mop-generated method using
+ CALL-NEXT-METHOD (reported by Pascal Costanza)
+ * bug fix: recursion is now permitted in accessors through
+ SLOT-UNBOUND. (reported by Pascal Costanza)
+ * bug fix: an error was signaled at startup if the HOME environment

+ signal a PROGRAM-ERROR, not a BUG.
+ * bug fix: SB-POSIX:READDIR works when built with large file support.
+ * bug fix: ENOUGH-NAMESTRING works relative to #p"/" as well. (thanks
+ to Marco Monteiro)
+ * enhancement: DESTRUCTURING-BIND lambda-list uses &BODY instead of &REST

+ proportional to the amount of methods in the generic function
+ (reported by Todd Sabin and Jeremy Brown)

+ (thanks to NIIMI Satoshi)
+ * improvement: runtime option --dynamic-space-size can be used
+ to set the size of the dynamic space reserved on startup.

+
+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.
+
+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
+
