+changes relative to sbcl-1.1.6
+ * bug fix: :allocation slot option works for condition slots
+ (lp#1049404)
+ * bug fix: redefining conditions does not lead to multiple evaluations of
+ hairy slot initfunctions anymore (lp#1164969)
+ * bug fix: CLASS-DIRECT-DEFAULT-INITARGS now works for condition classes
+ (lp#1164970)
+ * bug fix: function constants now work as initforms and default initarg
+ values of conditions (lp#539517)
+ * bug fix: svref/(setf svref) on symbol macros don't crash the compiler
+ anymore. (Minimal test case provided by James M. Lawrence on sbcl-devel)
+ * bug fix: no more bogus ## references when pretty printing backquoted
+ forms with non-trivial structure sharing. (lp#1161218)
+ * bug fix: Don't signal an error on (setf (documentation nil 'function) "doc").
+ Signal a style-warning instead when trying to set documentation of NIL
+ for all other documentation types.
+ Reported by Zach Beane. Regression since 2e52fa05.
+ * LOGBITP and LOGTEST optimizations from x86 ported to x86_64.
+
+changes in sbcl-1.1.6 relative to sbcl-1.1.5:
+ * enhancement: the continuable error when defknown-ing over extant
+ fndb entries can be ignored by passing :overwrite-fndb-silently t
+ as a keyword argument to sb-c:defknown (after attributes). Useful
+ to allow defknown to be re-loaded. Use with :allow-other-keys t
+ for backward compatibility.
+ * optimization: compiler is much faster in compiling SVREF and (SETF SVREF)
+ forms.
+ * bug fix: Prevent a make-array transform from modifying source forms
+ causing problems for inlined code. Thanks to Bart Botta.
+ (regression since 1.0.42.11-bis)
+ * bug fix: clear-output calls the correct gray stream routine,
+ sb-gray:stream-clear-output. (lp#1153257)
+ * bug fix: an error is signalled for an invalid format modifier: ~<~@>.
+ (lp#1153148)
+ * bug fix: Better error messages for package operations (lp#1154776)
+ * bug fix: delete-package on a nonexistent package should signal a cerror.
+ (regression since 1.0.37.44).
+ * bug fix: accessing &MORE (stack allocated &REST) arguments checks bounds.
+ (lp#1154946, lp#1072112)
+ * bug fix: compiling make-array no longer signals an error when the
+ element-type is an uknown type, a warning is issued instead.
+ Thanks to James Kalenius (lp#1156095)
+ * bug fix: SEARCH on generic (non-VECTOR non-LIST) sequence types no longer
+ produces wrong results for some inputs. (Thanks to Jan Moringen.)
+ (lp#1153312)
+
+changes in sbcl-1.1.5 relative to sbcl-1.1.4:
+ * minor incompatible change: SB-SPROF:WITH-PROFILING no longer loops
+ by default.
+ * new feature: package local nicknames. See manual for details.
+ * new feature: SB-EXT:MAP-DIRECTORY provides a powerful interface for
+ directory traversal: it is the backend used by SBCL for CL:DIRECTORY.
+ * enhancement: easier to use restarts for resolving name-conflicts
+ resulting from IMPORT, EXPORT, or USE-PACKAGE.
+ * enhancement: variant DEFPACKAGE forms now signal a full error with
+ restarts provided for resolving the situation. (lp#891351)
+ * enhancement: by setting SB-EXT:*ON-PACKAGE-VARIANCE* appropriately variant
+ DEFPACKAGE forms can now signal a full error with restarts provided for
+ resolving the situation. See manual for details. (lp#891351)
+ * enhancement: make-random-state now uses CryptGenRandom as a seed on Windows.
+ (Thanks to Anton Kovalenko.) (lp#1102748)
+ * enhancement: backtrace improvements
+ ** secondary CLOS dispatch functions have better debug names (lp#503081)
+ ** easier to read method names in backtraces. See
+ SB-DEBUG:*METHOD-FRAME-STYLE*.
+ ** SB-DEBUG:PRINT-BACKTRACE and SB-DEBUG:LIST-BACKTRACE are available as
+ forwards-compatible replacements for SB-DEBUG:BACKTRACE and
+ SB-DEBUG:BACKTRACE-AS-LIST.
+ ** SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS** has been deprecated, as the same
+ information is available in less intrusive form as frame annotations.
+ * enhancement: SB-POSIX now provides MAP-ANON.
+ * enhancement: test-suite results are colorized, failures in red, unexpected
+ success in green. Works on Windows and on terminals with ANSI escape code
+ support. Can be disabled with --no-color.
+ * optimization: SB-CONCURRENCY:QUEUE implementation is more efficient.
+ (thanks to James M. Lawrence)
+ * bug fix: no more unused variable style warnings from RESTART-CASE
+ macroexpansion (lp#1113859)
+ * bug fix: no more unused variable style warnings when loading
+ sb-bsd-sockets.asd (lp#1114681)
+ * bug fix: deleting a package removes it from implementation-package
+ lists of other packages.
+ * bug fix: SB-SPROF:WITH-PROFILING is now usable in the Slime REPL on Darwin.
+ This does not fix the occasional "interrupt already pending" issue, though.
+ * bug fix: (setf (documentation 'x 'function)) and
+ (setf (documentation #'x t)) set documentation in different places.
+ (regression since 1.0.43.63)

+
+changes in sbcl-1.1.4 relative to sbcl-1.1.3:
+ * optimization: LOOP expressions using "of-type character" have slightly
+ more efficient expansions.
+ * bug fix: very long (or infinite) constant lists in DOLIST do not result
+ in very long compile times or heap exhaustion anymore. (lp#1095488)
+ * bug fix: `#3(1) is read as #(1 1 1), not as #(1). (lp#1095918)
+ * bug fix: adjust-array ignored :initial-element for simple-vectors.
+ (lp#1096359)
+ * bug fix: optimizations to MAKE-INSTANCE with literal list initargs no
+ longer cause infinite loops (on circular data) or violate eqlity
+ constraints. (lp#1099708)
+ * bug fix: FIRST was not being open coded. (regression from 1.1.0)
+
+changes in sbcl-1.1.3 relative to sbcl-1.1.2:
+ * enhancement: warnings about bad locale settings, LANG, LC_CTYPE, etc.
+ (lp#727625)
+ * enhancement: support for C-c to interrupt the foreground thread
+ on Windows. (Thanks to Anton Kovalenko.)

+ * enhancement: Safepoint builds on POSIX platforms can now optionally be
+ built without pseudo-atomic sequences and their run-time overhead.
+ * enhancement: Threads created outside of Lisp can enter Lisp through
+ alien callbacks and appear as Lisp threads for the duration of that
+ function invocation. On safepoint builds only.
+ * enhancement: Miscellaneous improvements to namestrings and underlying
+ calls to OS functions for file system access on Windows. (Thanks to
+ Anton Kovalenko.)
+ * enhancement: The MSI installer support for Windows now uses Windows
+ Installer XML at least version 3.5 and includes various usability
+ improvements. (Thanks to Dmitry Kalyanov and Anton Kovalenko.)

+ on Windows. (Thanks to Anton Kovalenko.)
+ * enhancement: The Windows backend now supports the x86-64 platform.
+ (Thanks to Anton Kovalenko.)
+ * bug fix: fasls are now once again directly executable (on platforms
+ supporting shebang lines, with a suitably-installed sbcl).
+ * bug fix: make.sh --help no longer runs clean.sh. (lp#937001)
+ * bug fix: Fix CAS access to slots of direct instances of structure classes
+ in the presence of subclasses sharing the same conc-name.
+ * bug fix: Logical pathname namestrings on Windows have been changed to
+ be lower-case, to minimize differences between POSIX and Windows.
+
+changes in sbcl-1.1.2 relative to sbcl-1.1.1:
+ * notice: System requirements for SBCL on Microsoft Windows: Windows NT 5.1
+ or newer (Windows XP, Server 2003) is required. Support for Windows 2000
+ (NT 5.0) is no longer being maintained.
+ * notice: Starting with this version, SBCL on Windows no longer supports
+ building with disabled thread support.
+ * enhancement: frlocks have been added to SB-CONCURRENCY contrib module.
+ * enhancement: New feature sb-dynamic-core allows the runtime to be
+ rebuilt or relocated without requiring changes to the core file on
+ all linkage table platforms. Required on Windows. (Thanks to Anton
+ Kovalenko.)
+ * enhancement: Console I/O streams use UCS-2. (Thanks to Anton Kovalenko.)
+ * enhancement: I/O on Windows unnamed pipes is interruptible
+ asynchronously using interrupt-thread, timers when running on Windows NT
+ version 6.1 or newer (Windows 7, Server 2008 R2). (Thanks to Anton
+ Kovalenko.)
+ * enhancement: Support for the experimental safepoint-based stop-the-world
+ protocol on the PowerPC platform.
+ * bug fix: Non-blocking reads from the Windows console were not necessarily
+ non-blocking. Thanks to Anton Kovalenko. (lp#308923)
+ * bug fix: stability of threads on Windows has been improved upon through
+ an updated stop-the-world protocol (thanks to Anton Kovalenko).
+
+changes in sbcl-1.1.1 relative to sbcl-1.1.0:
+ * enhancement: WITH-COMPILATION-UNIT no longer grabs the world-lock.
+ (COMPILE and COMPILE-FILE still do.)
+ * optimization: the SPARC backend now supports the precise generational
+ (GENCGC) garbage collection. Enabled by default on Solaris/SPARC and
+ Linux/SPARC. Thanks to Raymond Toy (via CMUCL).
+ * enhancement: add experimental support for the SB-THREAD feature and the
+ timer facility on Windows. Thanks to Dmitry Kalyanov and Anton Kovalenko.
+ Threads are enabled by default, and this version of SBCL is considered
+ to be the last and final release to officially support building with
+ threads disabled.
+ * optimization: The compiler no longer rotates loops in some cases where
+ this transformation actually lead to worse code being generated.
+ * bug fix: SB-CLTL2:MACROEXPAND-ALL correctly handles shadowing of
+ symbol-macros by lexical bindings.
+ * bug fix: stack allocation was prevented by high DEBUG declaration in
+ several cases.
+ * bug fix: SB-EXT:GC-LOGFILE signaled an error when no logfile was set.
+ (thanks to SANO Masatoshi)
+ * bug fix: PARSE-NATIVE-NAMESTRING performed non-native parsing when
+ :JUNK-ALLOWED was true.
+ * bug fix: type derivation inferred overly conservative types for
+ unions of array types. (lp#1050768)
+
+changes in sbcl-1.1.0 relative to sbcl-1.0.58:
+ * enhancement: New variable, sb-ext:*disassemble-annotate* for controlling
+ source annotation of DISASSEMBLE output. Defaults to T.
+ * enhancement: TIMEOUT arguments added to WITH-MUTEX and WITH-RECURSIVE-LOCK, and
+ WAIT-P argument added to WITH-RECURSIVE-LOCK.
+ * enhancement: SB-EXT:ATOMIC-PUSH and SB-EXT:ATOMIC-POP allow atomic operations
+ on list heads.
+ * enhancement: Optional features (not enabled by default) allow the
+ use of signals for inter-thread synchronization to be reduced on certain
+ supported platforms (currently Linux, Solaris, and FreeBSD on x86 and
+ x86-64). Set (and :sb-thread :sb-safepoint :sb-thruption :sb-wtimer)
+ to test these experimental features. Known remaining bugs include minor
+ thread safety issues, less timely freeing of memory by GC, and certain
+ (not yet optimally low) runtime overhead. Thanks to Anton Kovalenko.
+ * optimization: CL:SORT and CL:STABLE-SORT of lists are faster and use fewer
+ comparisons, particularly on almost-sorted inputs.
+ * bug fix: Reading floats with large exponents no longer takes too much time
+ before reporting that the exponent is too large.
+ * bug fix: SB-BSD-SOCKETS:SOCKET-RECEIVE with a UDP socket now works
+ correctly when the received datagram is larger than the provided buffer.
+ (lp#1023438, thanks to Robert Uhl)
+ * bug fix: SB-EXT:GET-CAS-EXPANSION returned a bogus read-form when given
+ a SYMBOL-VALUE form with a constant symbol argument.
+ * bug fix: SB-EXT:GET-CAS-EXPANSION signaled an error when a macro expanding
+ into a DEFCAS defined place was used as the place.
+ * bug fix: FIND and POSITION signaled a type-error when non-bits where looked
+ for from bit-vectors.
+ * bug fix: a race condition around thread creation could (in SBCL 1.0.57)
+ lead to internal errors or crashes (lp#1058799).
* documentation: a section on random number generation has been added to the
manual. (lp#656839)
