+changes in sbcl-1.0.8 relative to sbcl-1.0.7:
+ * enhancement: closed over variables can be stack-allocated on x86 and
+ x86-64.
+
+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.
+
+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.
+ * bug fix: bad type declaration in the CLOS implementation has
+ been fixed. (reported by James Anderson)
+ * bug fix: incorrect ROOM reporting on x86-64 has been fixed.
+ (thanks to Lutz Euler)

+ 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
+ handlers for dealing with illegal instructions (for trapping and
+ 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)

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

+ x86/macos. requires building with :MACH-EXCEPTION-HANDLER feature
+ to use.
+ * improvement: support for GBK external format.
+ (thanks to Chun Tian (binghe))
+ * improvement: the debugger now displays variables that have been closed
+ over, in code compiled with (DEBUG 2) or higher

+ 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)

+ 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

+ 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)

+ to Alastair Bridgewater)
+ ** TRACE :ENCAPSULATE NIL (and function end breakpoints)
+ work on Windows.
+ ** Lisp is able to unwind foreign exception frames from alien
+ callbacks. (thanks to Alastair Bridgewater)

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

+ * improvement: the debugger will now also display local variables that
+ are only used once, for code compiled with a DEBUG optimization quality

+
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
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
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: arguments to RUN-PROGRAM are escaped correctly on win32
- (thanks to Yaroslav Kavenchuk)
* 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
changes in sbcl-0.9.16 relative to sbcl-0.9.15:
