+;;;; -*- coding: utf-8; -*-
+changes in sbcl-0.9.4 relative to sbcl-0.9.3:
+ * optimizations: REMOVE-DUPLICATES now runs in linear time on
+ lists in some cases. This partially fixes bug 384.
+
+changes in sbcl-0.9.3 relative to sbcl-0.9.2:
+ * New feature: Experimental support for bivalent streams: streams
+ opened with :element-type :default now allow character and binary
+ (unsigned-byte 8) I/O
+ * Support for the koi8-r external format. (thanks to Ivan Boldyrev)
+ * Bug fix: OPEN no longer fails when *PRINT-READABLY* is T. (thanks
+ to Zach Beane)
+ * bug fix: no more highly sporadic "couldn't check whether ~S is
+ readable" when reading a stream and an interrupt hits in the middle
+ of a select system call
+ * compiler better recognizes complex arrays (reported by Eduardo
+ Muñoz)
+ * bug fix: out-of-line SB-SYS:FOREIGN-SYMBOL-ADDRESS did not work
+ for variables on SBCL built with linkage-tables. (reported by Luis
+ Oliveira)
+ * various error reporting improvements.
+ * optimizations: LOGNOR on fixnums is improved in the MIPS backend.
+ (Thanks to Thiemo Seufer)
+ * bug fix: nested reader invokations work correctly
+ * bug fix: it is possible to have simultaneous references to foreign
+ code and foreign data with the same name.
+ * threads
+ ** added x86-64 support
+ ** incompatible change: the threading api now works with thread
+ objects instead of thread ids
+ ** bug fix: threads are protected from signals and interruption when
+ starting up or going down
+ ** bug fix: a race where an exiting thread could lose its stack to gc
+ ** bug fix: don't halt on infinite error in threads if possible
+ ** fixed numerous gc deadlocks introduced in the pthread merge
+ ** bug fix: fixed thread safety issues in read and print
+ ** bug fix: debugger doesn't hang on session lock if interrupted at
+ an inappropriate moment
+ ** bug fix: run-program is now thread safe(r)
+ ** bug fix: inner with-recursive-lock no longer releases the mutex
+ * fixed a bug in (DECODE-UNIVERSAL-TIME 0) (reported by Paul Dietz)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** TYPE-ERRORs from signalled by COERCE now have DATUM and
+ EXPECTED-TYPE slots filled.
+ ** MULTIPLE-VALUE-SETQ always returns the primary value of the
+ values form.
+ ** MAKE-CONDITION accepts classes as type-designators.
+ ** COMPILE may never return NIL.
+ ** ENCODE-UNIVERSAL-TIME now guards against times out of Unix's
+ range before calling Unix time functions
+
+changes in sbcl-0.9.2 relative to sbcl-0.9.1:
+ * numerous signal handling fixes to increase stability
+ * Support for EUC-JP external format. (thanks to NIIMI Satoshi)
+ * minor incompatible change: we now correctly canonize default
+ initargs, making them be a list of (INITARG INITFORM INITFUNCTION)
+ as per the MOP, rather than the historical (INITARG INITFUNCTION
+ INITFORM). (reported by Bruno Haible)
+ * new feature: WITH-COMPILATION-UNIT now accepts a non-standard
+ :SOURCE-PLIST option. See (DOCUMENTATION #'WITH-COMPILATION-UNIT T)
+ for more information.
+ * TRUENAME and PROBE-FILE now correctly resolve symlinks even if the
+ pathname is a directory pathname.
+ * SB-SPROF now works (more) reliably on non-GENCGC platforms.
+ * dynamic space size on PPC has been increased to 768Mb. (thanks to
+ Cyrus Harmon)
+ * SB-MOP:ENSURE-CLASS-USING-CLASS now accepts a class as the
+ :METACLASS argument in addition to a class name. (reported by
+ Bruno Haible for CMUCL, patch for CMUCL by Gerd Moellmann)
+ * RESTART-CASE can now be wrapped around CALL-METHOD forms.
+ (reported by Bruno Haible; patch from Gerd Moellmann)
+ * bug fix: sbcl runtime can now be compiled with gcc4 (thanks to
+ Sascha Wilde)
+ * bug fix: more cleanups to the floating point exception handling on
+ x86-64 (thanks to James Knight)
+ * bug fix: the compiler does not try to constant fold calls of
+ COERCE and BIT-* functions when they return freshly constructed
+ objects. (reported by Nikodemus Siivola and Paul Dietz)
+ * optimization: improved the MIPS versions of generic (in the
+ generic sense) arithmetic routines. (thanks to Thiemo Seufer)
+ * optimization: direct conversion of (unsigned-byte 32) to floats on
+ the PowerPC platform.
+ * optimization: structure instances with raw slots now use less
+ memory, and probably show better memory locality. (thanks to
+ David Lichteblau)
+ * optimization: DYNAMIC-EXTENT declarations for lists and closures
+ are treated as requests for stack allocation on the x86-64,
+ Alpha-32, PPC and SPARC platforms.
+ * contrib improvement: it's harder to cause SOCKET-CLOSE to close()
+ the wrong file descriptor; implementation of SOCKET-OPEN-P.
+ (thanks to Tony Martinez)
+ * threads
+ ** gcing a dead thread can no longer lead to lockups
+ ** threads block signals until they are set up properly
+ ** errno is no longer shared by threads
+ ** interrupt-thread restores the eflags register on x86
+ ** fixed some lockups due to gc/thread interaction
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** invalid dotted lists no longer raise a read error when
+ *READ-SUPPRESS* is T
+ ** signal an error if a symbol that names a declaration is used
+ as the name of a type, or vice versa
+ ** allow using the (declare (typespec var*)) abbreviation for
+ (declare (type typespec var*)) with all type specifiers
+ ** circularity detection works properly with PPRINT-LOGICAL-BLOCK
+ ** always return NIL from PPRINT-POP when OBJECT is NIL
+ ** don't signal errors when pretty-printing malformed LABELS,
+ FLET or MACROLET forms
+ ** declarations in a DOLIST body are also in scope for the
+ DOLIST return-form
+ ** COMPILE-FILE accepts all pathname designators as INPUT-FILE
+ and OUTPUT-FILE
+ ** the ELEMENT-TYPE keyword argument to WITH-OUTPUT-STREAM is
+ always evaluated
+
+changes in sbcl-0.9.1 relative to sbcl-0.9.0:
+ * fixed cross-compiler leakages that prevented building a 32-bit
+ target with a 64-bit host compiler.
+ * fixed a bug in CLOSE :ABORT T: no longer attempts to remove files
+ opened with :IF-EXISTS :OVERWRITE.
+ * fixed bug 281: error for an invalid qualifier in a short-form method
+ combination method is not signalled until the faulty method is called.
+ * bug fix: iteration variable type inferrer failed to deal with open
+ intervals. (reported by Alan Shields)
+ * bug fix: dynamically loading (via LOAD-SHARED-OBJECT or similar)
+ "frameworks" on Mac OS X no longer causes an EXC_BAD_ACCESS if two
+ or more runtime options were provided to the sbcl binary.
+ * compiled code is not steppable if COMPILATION-SPEED >= DEBUG.
+ * contrib improvement: implement SB-POSIX:MKSTEMP (Yannick Gingras)
+ * optimization: there's now a fast-path for fixnum arguments in the
+ generic subtraction routines on x86/x86-64. (Thanks to Lutz Euler)
+ * optimization: the code generated on x86-64 is more compact thanks
+ to not outputting unneccessary prefix bytes. (Thanks to Lutz Euler)
+ * bug fix: floating-point exception handling now partly works on
+ x86-64. (Thanks to James Knight)
+ * improvement to the MIPS backend from Thiemo Seufer: C-style
+ 64-bit long long arguments and return values to alien functions
+ are now supported.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** the type-error signalled from WARN has a filled-in DATUM slot.
+ ** the type-error required when a stream is not associated with
+ a file has the stream as its datum.
+ ** type-errors on single-floats on x86-64 no longer have
+ :INVALID-OBJECT as the datum
+ ** the type-errors signalled for invalid function names now have
+ a correct expected type
+ ** (SETF (DOCUMENTATION ... 'STRUCTURE)) no longer signals an error
+ for structures defined with a :TYPE. Documentation strings for
+ typed structures are no longer immediately discarded
+ ** FILE-STRING-LENGTH and STREAM-EXTERNAL-FORMAT now work on
+ broadcast streams and synonym streams. FILE-LENGTH now also works
+ on broadcast streams.
+
+changes in sbcl-0.9.0 relative to sbcl-0.8.21:
* incompatible change: the --noprogrammer option, deprecated since
version 0.7.5, has been removed. Please use the equivalent
--disable-debugger option instead.
to Wendall Marvel)
* on x86 compiler supports stack allocation of results of simple
calls of MAKE-ARRAY, bound to variables, declared DYNAMIC-EXTENT.
+ * support for building and running on Mac OS X 10.4 "Tiger" has been added
+ ** Binaries built on Tiger will not run on 10.2 "Jaguar" currently
* fixed some bugs related to Unicode integration:
** the restarts for recovering from input and output encoding
errors only appear when there is in fact such an error to
