+changes in sbcl-1.0.17 relative to 1.0.16:
+ * temporary regression: user code can no longer allocate closure
+ variable storage on stack, due to bug 419 without explicitly
+ requesting it. Please consult sbcl-devel for advice if you need to
+ use this feature in the meanwhile.
+ * new feature: runtime argument --control-stack-size can be used to
+ adjust thread default control stack size.
+ * optimization: ADJOIN and PUSHNEW are upto ~70% faster in normal
+ SPEED policies.
+ * optimization: APPEND is upto ~10% faster in normal SPEED policies.
+ * optimization: two argument forms of LAST are upto ~10% faster
+ in normal SPEED policies.
+ * optimization: NCONC no longer needs to heap cons its &REST list
+ in normal SPEED policies.
+ * bug fix: result of MAKE-ARRAY can be stack allocated - regression
+ since 1.0.15.36. (thanks to Paul Khuong)
+ * bug fix: bogus errors when generating certain code sequences, due
+ to the compiler not accepting ANY-REG for primitive type T on x86
+ and x86-64. (reported by Stelian Ionescu.)
+ * bug fix: LAST when always returned the whole list when given a bignum
+ as the second argument.
+ * bug fix: dynamic extent allocation of nested lists and vectors
+ could leak to otherwise accessible parts.
+ * bug fix: invalid optimization of heap-allocated alien variable
+ reference.
+ * bug fix: fasl header checking is less vulnerable to different
+ platform word lengths.
+ * bug fix: more correct assembler syntax for GNU binutils
+ 2.18.50.0.4 support. (thanks to Marijn Schouten)
+ * bug fix: fix ECASE warnings from CMUCL-as-xc-host. (reported by
+ Andreas Franke)
+
+changes in sbcl-1.0.16 relative to 1.0.15:
+ * minor incompatible change: revert the changes to sb-posix's error
+ signaling added in 1.0.14.
+ * minor incompatible change: change PROBE-FILE back to returning
+ NIL whenever we can't get a truename, as was the case before 1.0.14.
+ * minor incompatible change: SB-BSD-SOCKETS:NAME-SERVICE-ERROR now
+ inherits from ERROR instead of just CONDITION.
+ * new feature: SB-INTROSPECT can provide source locations for instances
+ as well. (thanks to Tobian Ritterweiler)
+ * optimization: binding special variables now generates smaller code
+ on threaded platforms.
+ * optimization: MEMBER and ASSOC are over 50% faster for :TEST #'EQ
+ and cases where no :TEST is given but the compiler can infer that
+ the element to search is of type (OR FIXNUM (NOT NUMBER)).
+ * optimization: better LOGNOT on fixnums.
+ * optimization: modular arithmetic for a particular requested width
+ is implemented using a tagged representation unless a better
+ representation is available.
+ * fixed bug 423: TRULY-THE and *CHECK-CONSISTENCY* interaction.
+ * bug fix: SB-BSD-SOCKETS:MAKE-INET-ADDRESS checks the input string
+ for wellformedness and returns a specialized vector. (reported by
+ Francois-Rene Rideau)
+ * bug fix: FIND-CLASS was not thread-safe. (reported by Attila Lendvai)
+ * bug fix: ~R was broken for vigtillions. (thanks to Luis Oliveira)
+ * bug fix: attempt to obtain *SCHEDULER-LOCK* recursively when
+ unscheduling timer at the same time as another timer fires.
+ * bug fix: don't reschedule timers for dead threads.
+ * bug fix: periodic polling was broken. (thanks to Espen S Johnsen)
+ * bug fix: copying output from RUN-PROGRAM to a stream signalled
+ bogus errors if select() was interrupted.
+ * enhancement: add support for fcntl's struct flock to SB-POSIX.
+
+changes in sbcl-1.0.15 relative to sbcl-1.0.14:
+ * enhancement: cleaner backtraces for interactive interrupts, as
+ well as other cases where the interesting frames used to be
+ obscured by interrupt handling frames.
+ * enhancement: untracing a whole package using (UNTRACE "FOO") is
+ now supported, and tracing a whole package using (TRACE "FOO") now
+ traces SETF-functions as well.
+ * enhancement: implement SB-POSIX:MKTEMP and SB-POSIX:MKDTEMP.
+ * SB-DEBUG:PRINT-FRAME-CALL now prints the entry-point kind even
+ when SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS* is NIL.
+ * unreadably printed representation of hash-tables now includes
+ weakness if any.
+ * bug fix: partially fixed #188: type propagation from assignments
+ is now more efficient.
+ * bug fix: fixed #407: (COERCE X 'SINGLE-FLOAT) and (COERCE X
+ 'DOUBLE-FLOAT) are not flushable.
+ * bug fix: on x86 and x86-64 pointer based EQ-hashing now uses the
+ full address of the object, and none of the tag bits.
+ * bug fix: readably printing hash-tables now respects other printer
+ control variables. (reported by Cedric St-Jean)
+ * bug fix: compiler gave a bogus STYLE-WARNING for the :SYNCHRONIZED
+ keyword with MAKE-HASH-TABLE.
+ * bug fix: export SB-POSIX:MKSTEMP.
+ * bug fix: SORT was not interrupt safe.
+ * bug fix: XREF accounts for the last node of each basic-block as
+ well.
+ * bug fix: MAKE-INSTANCE optimizations interacted badly with
+ non-keyword :DEFAULT-INITARGS in the presence of :BEFORE/:AFTER
+ methods on SHARED-INITIALIZE. (thanks to Matt Marjanovic)
+ * bug fix: the CTOR optimization for MAKE-INSTANCE should no longer
+ create obsolete instances in the case of redefinition or
+ obsoletion of a superclass. (thanks to Andy Hefner)
+ * bug fix: Support for the Alpha architecture has been revived; it had
+ suffered somewhat from lack of maintenance since sbcl-1.0.
+ * improvements to the Windows port:
+ ** The system detects the codepage to use at startup, instead of
+ using the value from the saved core. (thanks to Kei Suzuki)
+
changes in sbcl-1.0.14 relative to sbcl-1.0.13:
* new feature: SB-EXT:*EXIT-HOOKS* are called when the process exits
(see documentation for details.)
- * Revived support for OpenBSD (contributed by Josh Elsasser)

+ * partially fixed bug #108: ROOM no longer suffers from occasional
+ (AVER (SAP= CURRENT END)) failures.
+ * fixed bug #402: proclaimed non-standard declarations in DEFMETHOD
+ bodies no longer cause a WARNING to be signalled. (reported by
+ Vincent Arkesteijn)
+ * bug fix: (TRUNCATE X 0) when X is a bignum now correctly signals
+ DIVISION-BY-ZERO. Similarly for MOD and REM (which suffered due to
+ the bug in TRUNCATE.) (reported by Michael Weber)
+ * bug fix: SB-SPROF:REPORT no longer signals an error if there are
+ no samples. (reported by Andy Hefner)
+ * bug fix: functions compiled using (COMPILE NIL '(LAMBDA ...))
+ no longer appear as (NIL ...) frames in backtraces.

+ single-floats on 64-bit platforms where single-floats are not boxed.
+ * bug fix: SB-MOP:CLASS-SLOTS now signals an error if the class has not
+ yet been finalized. (reported by Levente Meszaros)
+ * bug fix: CLOSE :ABORT T behaves more correctly on Windows.
+ * DESCRIBE and (DOCUMENTATION ... 'OPTIMIZE) describe meaning of
+ SBCL-specific optimize qualities.
changes in sbcl-1.0.13 relative to sbcl-1.0.12:
* minor incompatible change: RUN-PROGRAM now uses execvp(3) to find
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
+ checks has changed: now type checks are weakened only if SAFETY < 2
and SAFETY < SPEED.
* SB-EXT:NATIVE-NAMESTRING takes a new keyword AS-FILE, forcing
unparsing of directory pathnames as files. Analogously,
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
+ * optimization: CONCATENATE on strings is an order of magnitude 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.
could cause buffer-overflows.
* bug fix: source location information is stored correctly
(broken since 1.0.6). This bug would generally show up as the
- Slime debugger higlighting the wrong form when the sldb-show-source
+ Slime debugger highlighting the wrong form when the sldb-show-source
command was used.
* bug fix: Branch forms are again annotated as branches in the sb-cover
annotations.
* enhancement: experimental macro SB-EXT:COMPARE-AND-SWAP provides
atomic compare-and-swap operations on threaded platforms.
* enhancement: experimental function SB-EXT:RESTRICT-COMPILER-POLICY
- allows assining a global minimum value to optimization qualities
+ allows assigning a global minimum value to optimization qualities
(overriding proclamations and declarations).
* enhancement: closed over variables can be stack-allocated on x86
and x86-64.
* bug fix: number of characters that can be written onto a single
line in a file is unlimited.
* bug fix: some GC deadlocks caused by asynchronous interrupts have
- been fixed by inhibiting interrupts for when GC is disbled.

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)
+ about function calls (who-calls), macroexpansion (who-macroexpands)
and special variables (who-binds, who-sets, who-references) for code
