+changes in sbcl-1.0.20 relative to 1.0.19:
+ * bug fix: fixed #427: unused local aliens no longer cause compiler
+ breakage. (reported by Stelian Ionescu, Andy Hefner and Stanislaw
+ Halik)
+ * bug fix: non-local exit from a WITH-ALIEN form no longer causes
+ alien-stack leakage. (reported by Andy Hefner)
+ * bug fix: PROGV signals an error when an attempt to violate declared
+ type of a variable or bind a constant is made.
+ * bug fix: SET signals an error when an attempt to violate declared
+ type of a variable is made.
+
+changes in sbcl-1.0.19 relative to 1.0.18:
+ * new feature: user-customizable variable SB-EXT:*MUFFLED-WARNINGS*;
+ warnings that go otherwise unhandled will be muffled if they are
+ of the type that's the value of this variable.
+ * optimization: stack allocation is slightly more efficient on x86
+ and x86-64.
+ * bug fix: DEFSTRUCT forms with user-specified :CONSTRUCTOR options,
+ where a raw slot always is initialized using the initform whose
+ type is not know sufficiently well a compile-time are now compiled
+ correctly. (reported by John Morrison)
+ * bug fix: compiler no longer makes erronous assumptions in the
+ presense of non-foldable SATISFIES types.
+ * bug fix: stack analysis missed cleanups of dynamic-extent
+ arguments in non-let-converted calls to local functions.
+ * improvements to the Windows port:
+ ** adjusted address spaces for building on both Win32 and
+ Win64. (thanks for John Connors)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** interval arithmetic during type derivation used inexact integer
+ to single-float coercions.
+ ** arithmetic operations involving large integers and single
+ floats give the same results in compiled and interpreted code.
+ ** deriving the result type of COERCE no longer signals an error
+ if the derived type of the second argument is a MEMBER type
+ containing invalid type specifiers.
+ ** ADJOIN with constant NIL as second argument works correctly.
+ ** FUNCTION-KEYWORDS was called SB-PCL::FUNCTION-KEYWORD-PARAMETERS.
+
+changes in sbcl-1.0.18 relative to 1.0.17:
+ * minor incompatible change: SB-SPROF:WITH-PROFILING now by default
+ profiles only the current thread.
+ * minor incompatible change: changes to SYMBOL-VALUE of constants
+ defined with DEFCONSTANT now signal an error.
+ * enhancement: SB-SPROF now has support for wallclock profiling,
+ and is also able to profile specific threads. REPORT output
+ has also additional sorting options.
+ * enhancement: better pretty-printing of DEFPACKAGE forms. (Thanks
+ to Michael Weber)
+ * optimization: structure allocation has been improved
+ ** constructors created by non-toplevel DEFSTRUCTs are ~40% faster.
+ ** out of line constructors are ~10% faster.
+ ** inline constructors are ~15% faster.
+ ** inline constructors are capable of dynamic extent allocation
+ (generally on x86 and x86-64, in some cases on other platforms
+ as well.)
+ * optimization: simple uses of HANDLER-CASE and HANDLER-BIND no
+ longer cons.
+ * optimization: file compiler is now able to coalesce non-circular
+ lists, non-base strings, and bit-vectors. Additionally, constants
+ are never referenced through SYMBOL-VALUE at runtime.
+ * optimization: code defining methods on PRINT-OBJECT (and other
+ generic functions in the COMMON-LISP package) now loads faster.
+ * bug fix: EAI_NODATA is deprecated since RFC 3493. Stop using it
+ in sb-bsd-sockets.
+ * bug fix: if COMPILE-FILE aborts due to an unwind, the partial
+ fasl is now deleted. (reported by Attila Lendvai)
+ * bug fix: READ-LINE always returned NIL for the last line in files.
+ (reported by Yoshinori Tahara)
+ * bug fix: more accurate disassembly annotations of foreign function
+ calls. (thanks to Andy Hefner)
+ * bug fix: trimming non-simple strings and non-string string
+ designators when the there is nothing to trim works properly.
+ (thanks to James Knight)
+ * new feature: SB-POSIX bindings for mlockall, munlockall, and setsid.
+ (thanks to Travis Cross)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** NIL is a valid function name (regression at 1.0.13.38)
+ ** FILL on lists was missing its return value (regression at 1.0.12.27)
+ ** STRING-TRIM, STRING-LEFT-TRIM, and STRING-RIGHT-TRIM did not respect
+ fill pointers properly (regression at 1.0.12.23)
+ ** STRING-TRIM, STRING-LEFT-TRIM, and STRING-RIGHT-TRIM did not respect
+ displacement indices properly (regression at 1.0.12.23)
+
+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.
+ * enhancement: improved TIME output
+ ** all times are reported using the measured accuracy (milliseconds
+ for real and GC times, microseconds for everything else.)
+ ** processor cycle counts on x86 and x86-64.
+ ** interpreted forms are counted for both evaluator modes.
+ ** number of lambdas converted by the compiler is reported.
+ ** CPU percentage report (computed from real and total run time.)
+ ** more comprehensive run time reporting, using a condenced format
+ ** interperted form, lambda, and page fault counts are omitted
+ when zero.
+ * 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: SB-FLUID build feature no longer breaks the build. (thanks
+ to Sidney Markowitz)
+ * bug fix: UNION and NUNION work with :TEST-NOT once more,
+ regression since 1.0.9.1. (thanks to Eric Marsden)
+ * bug fix: result of MAKE-ARRAY can be stack allocated - regression
+ since 1.0.15.36. (thanks to Paul Khuong)
+ * 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)
+ * bug fix: the fopcompiler can handle LOCALLY forms (with no
+ declarations) successfully. (reported by Attila Lendvai)
+
+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)
+

+ 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.
+ * bug fix: RESOLVE-CONFLICT (and the other name conflict machinery)
+ is now actually exported from SB-EXT as documented. (reported by
+ Maciej Katafiasz)
+ * bug fix: sb-aclrepl now correctly understands how to inspect

+ 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
+ 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 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,
SB-EXT:PARSE-NATIVE-NAMESTRING takes an AS-DIRECTORY, forcing a
filename to parse into a directory pathname.
- * optimization: SUBSEQ and COPY-SEQ are 30-80% faster for strings
- and vectors whose element-type or simplicity is not fully known at
- compile-time.
+ * 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
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: SUBSEQ is ~50% faster on lists.
* bug fix: bug 417 fixed -- source location reporting is now more robust.

* bug fix: Branch forms are again annotated as branches in the sb-cover
annotations.

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

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.
