+changes relative to sbcl-1.0.40:
+ * optimization: validity of observed keyword initargs to MAKE-INSTANCE is
+ cached, leading to many fewer expensive calls to
+ COMPUTE-APPLICABLE-METHODS.
+ * optimization: in the (unoptimized) general method for MAKE-INSTANCE on a
+ CLASS argument, search for and call an appropriate optimized ctor function
+ if it exists.
+ * bug fix: WRITE always returns the correct value.
+
+changes in sbcl-1.0.40 relative to sbcl-1.0.39:
+ * bug fix: readdir now works on :inode64 darwin builds (lp#592897)
+ * bug fix: Name conflicts between symbols passed as arguments to a single
+ call to IMPORT no longer add multiple symbols with the same name to the
+ package (detectable via DO-SYMBOLS).
+ * bug fix: support building without the dlshim on darwin x86 and x86-64
+ (lp#533470).
+ * bug fix: TRACE :ENCAPSULATE NIL now works on ppc/linux.
+
+changes in sbcl-1.0.39 relative to sbcl-1.0.38:
+ * bug fix: Backtrace from undefined function on x86 and x86-64 now show
+ the calling frame.
+ * bug fix: linkage-table entries on PPC now no longer overflow their
+ space allocation (potentially causing crashes if they are written out
+ of order).
+ * bug fix: Scrub control stack after scavenging in gencgc on non-x86oid
+ platforms, preventing the GC from seeing stale pointers on the control
+ stack in subsequent GCs (which would, and does, break invariants).
+ * bug fix: 32-bit unicode external formats now work on big-endian systems.
+ * bug fix: Literal characters with code points greater than about 32767
+ now work on PPC UNICODE builds.
+ * bug fix: Any noise left by SSE operations (sqrt and conversions) in the
+ high order bits are explicitly cleared out. In some contrived situations,
+ this could lead to wrong results in mixed real/complex float arithmetic.
+ * bug fix: Fix function/macro redefinition warnings when building with
+ clisp. (lp#576787, thanks to Josh Elsasser)
+ * new platform: experimental support for ppc/openbsd (thanks to Josh
+ Elsasser).
+ * bug fix: Floating-point traps now work on ppc/linux.
+
+changes in sbcl-1.0.38 relative to sbcl-1.0.37:
+ * incompatible change: Thread names are now restricted to SIMPLE-STRINGs
+ like for any other thread-related datastructure, MUTEX, etc. (lp#547095)
+ * deprecation: the SB-QUEUE contrib was merged into the SB-CONCURRENCY
+ contrib module. New code should depend on SB-CONCURRENCY, not SB-QUEUE.
+ * deprecation: SB-THEAD:GET-MUTEX was deprecated in favor of
+ SB-THREAD:GRAB-MUTEX.
+ * new contributed module: SB-CONCURRENCY is a new contrib; it's supposed to
+ contain additional data structures and tools for concurrent programming;
+ at the moment it contains a lock-free queue, and a lock-free mailbox
+ implementation.
+ * new feature: added SB-THREAD:GRAB-MUTEX; it's like the now deprecated
+ GET-MUTEX but takes &key rather than &optional parameters. Also added
+ :TIMEOUT argument to GRAB-MUTEX on non-sb-lutex platforms like Linux and
+ BSD.
+ * new feature: added SB-THREAD:TRY-SEMAPHORE, a non-blocking variant of
+ SB-THREAD:WAIT-ON-SEMAPHORE.
+ * new feature: SB-EXT:ATOMIC-DECF has been added as a companion to
+ SB-EXT:ATOMIC-INCF.
+ * new feature: a CANCEL-DEADLINE is associated with DEADLINE-TIMEOUT
+ conditions to defer the deadline for forever.
+ * enhancement: *STANDARD-OUTPUT*, *STANDARD-INPUT*, and *ERROR-OUTPUT* are
+ now bivalent.
+ * enhancement: errors from NO-APPLICABLE-METHOD and
+ NO-PRIMARY-METHOD now have a RETRY restart available to retry the
+ generic function call.
+ * enhancement: SB-BSD-SOCKET improvements
+ ** sockets and socket streams now have a more informative printed
+ representation based on the corresponding SOCKET-NAME and
+ SOCKET-PEERNAME.
+ ** SOCKET-MAKE-STREAM once more supports the :AUTO-CLOSE option.
+ (lp#540413)
+ ** SOCKET-CLOSE now accepts :ABORT argument, which is passed on to
+ CL:CLOSE when appropriate, and no longer disassociates the stream
+ from the socket if close failed. (lp#543951)
+ * improvements to the instrumenting profiler
+ ** new feature: report per-function GC overhead. (thanks to John Fremlin)
+ ** optimization: counters no longer use locks for the overflow mode.
+ ** bug fix: whenever a profiling counter wrapped into overflow mode, it
+ incurred an off-by-one miscount.
+ * enhancement: improved MAKE-HASH-TABLE documentation (lp#543473)
+ * enhancement: improved DEFMETHOD pretty-printing.
+ * enhancement: perform range reduction when arguments are too large for
+ x87's transcendentals (instead of returning 0). (lp#327192)
+ * enhancement: eliminate some spurious TYPE-WARNINGs. Should help with
+ some of CL-PPCRE's macros. (lp#570079)
+ * enhancement: our machine code is slightly less hostile to valgrind on
+ x86-64.
+ * enhancement: up-to-date versions of NetBSD-current are supported. (Thanks
+ to Robert Swindells and Aleksej Saushev)
* bug fix: correct restart text for the continuable error in MAKE-PACKAGE.
+ * bug fix: a rare case of startup-time page table corruption.
+ * bug fix: a semaphore with multiple waiters and some of them unwinding due
+ to timeouts could be left in an inconsistent state.
+ * bug fix: fix typo in "Reporting Bugs" section of the manual (lp#520366)
+ * bug fix: misoptimization of multiplication by one in
+ (SB-C::FLOAT-ACCURACY 0) policies.
+ * bug fix: miscounts in SB-PROFILE.
+ * bug fix: Fix lost wakeup bug between SB-THREAD:CONDITION-WAIT and
+ CONDITION-NOTIFY on Linux. See threads "lost wakeup in condition-wait /
+ condition-notify" (Feb 2010) and "Condition-Wait, Deadline handler, waking
+ up itself" (March 2010) for further details.
+ * bug fix: allow forward FIND and POSITION on lists to elide checking :END
+ against length of the list if the element is found before the specified
+ END is reached. (thanks to Alec Berryman, lp#554385)
+ * bug fix: errors signalled during package graph modification no longer
+ block FIND-SYMBOL and FIND-PACKAGE in other threads. (lp#511072)
+ * bug fix: SB-POSIX build was broken when SBCL was compiled without the
+ :SB-DOC feature. (lp#552564)
+ * bug fix: SB-INTROSPECT build issues on GENGC/PPC. (lp#490490)
+ * bug fix: more robust runtime executable path detection. (lp#375549)
+ * bug fix: GCD always returns positive values. (lp#413680)
+ * bug fix: Converting division to multiplication by reciprocal handles
+ denormals.
+ * bug fix: We were too eager in eliding range reduction tests on x87.
+ The maximal magnitude is 2^63, not 2^64.
+ * bug fix: Transforms for TRUNCATE don't die when the result is completely
+ ignored anymore.
+ * bug fix: Maybe restore buildability on Alpha.
+ * bug fix: READ-BYTE isn't inline anymore, fixing weird streams failures.
+ (lp#569404)
+ * bug fix: RANDOM-STATE can be printed readably again.
+ * bug fix: Unreadable objects were sometimes printed like #<\nFoo>.
+ * bug fix: Using EQL with non-constant values of constant type (e.g. EQL
+ types) could result in type mismatches during compilation.
changes in sbcl-1.0.37 relative to sbcl-1.0.36:
* enhancement: Backtrace from THROW to uncaught tag on x86oids now shows
