+changes in sbcl-1.0.13 relative to sbcl-1.0.12:
+ * minor incompatible change: RUN-PROGRAM now uses execvp(3) to find
+ an executable in the search path, and does so in the child
+ process's PATH. The function FIND-EXECUTABLE-IN-SEARCH-PATH has
+ been removed; it can be found in the CVS history, for somebody who
+ needs that search behavior (see the manual).
+ * minor incompatible change: compiler policy re. weakening type
+ checks has changed: now type checks are weakened on if SAFETY < 2
+ and SAFETY < SPEED.
+ * SB-EXT:NATIVE-NAMESTRING takes a new keyword AS-FILE, forcing
+ unparsing of directory pathnames as files. Analogously,
+ SB-EXT:PARSE-NATIVE-NAMESTRING takes an AS-DIRECTORY, forcing a
+ filename to parse into a directory pathname.
+ * enhancement: implicit generic function creation now signals a
+ specific style-warning IMPLICIT-GENERIC-FUNCTION-WARNING, which
+ users can bind handlers for and muffle around calls to LOAD.
+ * enhancement: RUN-PROGRAM allows unicode arguments and environments
+ to be used (using the default stream external format), and allows
+ non-simple strings to be used. (thanks to Harald Hanche-Olsen)
+ * optimization: COPY-SEQ, FILL, and SUBSEQ are 30-80% faster for
+ strings and vectors whose element-type or simplicity is not fully
+ known at compile-time.
+ * optimization: STRING-TRIM and related functions no longer allocate
+ a new string when no trimming needs to be performed. These functions
+ are also faster than before when the input string has been declared
+ as a simple-string.
+ * optimization: READ-SEQUENCE on simple-strings is up to 80% faster.
+ * optimization: READ-LINE is significantly faster for files containing
+ long lines.
+ * optimization: non-open coded uses of character comparison operators
+ (e.g. char=) no longer cons when called with more than one parameter
+ on platforms supporting dynamic-extent allocation.
+ * bug fix: READ-SEQUENCE on composite stream wrapping a Gray stream
+ with STREAM-ELEMENT-TYPE (UNSIGNED-BYTE 8) signalled an error.
+ * bug fix: COPY-SEQ on lists did not signal a type-error on improper
+ lists in safe code.
+ * bug fix: some sequence functions elided bounds checking when
+ SPEED > SAFETY.
+ * bug fix: too liberal weakening of union-type checks when SPEED >
+ SAFETY.
+ * bug fix: more bogus fixnum declarations in ROOM implementation
+ have been fixed.
+
+changes in sbcl-1.0.12 relative to sbcl-1.0.11:
+ * new feature: MAKE-HASH-TABLE now experimentally accepts a
+ :SYNCHRONIZED argument, which makes the hash-table safe for
+ concurrent accesses (but not iteration.) See also:
+ SB-EXT:WITH-LOCKED-HASH-TABLE, and
+ SB-EXT:HASH-TABLE-SYNCHRONIZED-P.
+ * optimization: CONCATENATE on strings is an order of magnitue faster
+ in code compiled with (> SPEED SPACE).
+ * optimization: SUBSEQ is ~50% faster on lists.
+ * bug fix: bug 417 fixed -- source location reporting is now more robust.
+ * bug fix: SUBSEQ on a list will now correctly signal an error if if
+ END is smaller then START.
+ * bug fix: SB-PROFILE will no longer report extra consing for nested
+ calls to profiled functions.
+ * bug fix: ROOM implementation had bogus fixnum declarations which
+ could cause type-errors when calling ROOM on large images.
+ * bug fix: if file compilation is aborted, the partial fasl is now
+ deleted, and COMPILE-FILE returns NIL as the primary value.
+ * bug fix: number of thread safety issues relating to SBCL's internal
+ hash-table usage have been fixed.
+ * bug fix: SB-SYS:WITH-PINNED-OBJECTS could cause garbage values to
+ be returned from its body when the values were being returned
+ using unknown-values return convection and the W-P-O was wrapped
+ inside an UNWIND-PROTECT.
+ * bug fix: sb-posix should now compile again under Windows, enabling
+ slime to work again.
+
+changes in sbcl-1.0.11 relative to sbcl-1.0.10:
+ * incompatible change: hash-table accessor functions are no longer
+ automatically protected by locks. Concurrent accesses on the same hash-table
+ from multiple threads can give inconsistent results or even corrupt the
+ hash-table completely. Multi-threaded applications should do their own
+ locking at the correct granularity. In the current implementation it is
+ still safe to have multiple readers access the same table, but it's not
+ guaranteed that this property will be maintained in future releases.
+ * minor incompatible change: (SETF MUTEX-VALUE) is not longer supported,
+ and will signal an error at runtime.
+ * enhancement: SB-THREAD package now exports a semaphore interface.
+ * enhancement: CONS can now stack-allocate on x86 and
+ x86-64. (Earlier LIST and LIST* supported stack-allocation, but
+ CONS did not.)
+ * enhancement: nested lists can now be stack allocated on
+ platforms providing stack allocation support.
+ * enhancement: dynamic-extent support has been extended to support
+ cases where there are multiple possible sources for the stack
+ allocated value.
+ * optimization: RELEASE-MUTEX no longer needs to perform a syscall
+ if the mutex is uncontested on Linux.
+ * bug fix: symbol-macro expansion now uses the *MACROEXPAND-HOOK*
+ as specified by the CLHS. (thanks to Tobias Rittweiler)
+ * bug fix: NaN comparison now works on x86-64.
+ * bug fix: CLOSE :ABORT T on a stream with pending output now
+ works.
+ * bug fix: instances of non-standard metaclasses using standard
+ instance structure protocol sometimes missed the slot type checks
+ in safe code.
+ * bug fix: known functions can be inlined in high-debug code.
+
+changes in sbcl-1.0.10 relative to sbcl-1.0.9:
+ * minor incompatible change: the MSI installer on Windows no longer
+ associates .lisp and .fasl files with the installed SBCL.
+ * minor incompatible change: :UNIX is no longer present in *FEATURES*
+ on Windows. (thanks to Luis Oliviera)
+ * new feature: SB-CLTL2 contrib module now implements
+ FUNCTION-INFORMATION. (thanks to Larry D'Anna)
+ * optimization: scavenging weak pointers is now more efficient,
+ requiring O(1) instead of O(N) per weak pointer to identify
+ scanvenged vs. unscavenged pointers. (thanks to Paul Khuong)
+ * optimization: typechecking (SETF SLOT-VALUE) is now ~5x faster in
+ method bodies using constant slot-names when the first argument is
+ a specializer parameter for the method.
+ * optimization: SLOT-VALUE &co are now ~50% faster for variable slot
+ names, when the class of the instance is a direct instance
+ STANDARD-CLASS or FUNCALLABLE-STANDARD-CLASS (making them only 3x
+ as slow as the constant slot-name case.)
+ * optimization: member type construction is now O(N) instead
+ of O(N^2).
+ * optimization: UNION and NUNION are now O(N+M) for large
+ inputs as long as the :TEST function is one of EQ, EQL, EQUAL, or
+ EQUALP.
+ * enhancement: DEFINE-MODIFY-MACRO lambda-list information is
+ now more readable in environments like Slime which display it.
+ (thanks to Tobias C. Rittweiler)
+ * bug fix: SB-EXT:COMPARE-AND-SWAP was non-atomic unless the compiler
+ was able to infer the correct argument type for the object on which
+ the CAS operation was being performed.
+ * bug fix: copy propagation interfered with parallel assignment
+ semantics in local calls. (reported by Paul Khuong)
+ * bug fix: the signed modular fixnum shift compiled to wrong code on
+ x86 and x86-64. (spotted by a slight modification to some of
+ PFD's random tests)
+
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,
