+changes in sbcl-1.0.22 relative to 1.0.21:
+ * bug fix: ADJUST-ARRAY on multidimensional arrays used bogusly give
+ them a fill pointer unless :DISPLACED-TO or :INITIAL-CONTENTS were
+ provided. (reported by Cedric St-Jean)
+ * bug fix: circularity handling in the reader did not treat raw
+ structure slots correctly. (reported by Cedric St-Jean)
+
+changes in sbcl-1.0.21 relative to 1.0.20:
+ * new feature: the compiler is able to track the effective type of a
+ generic function across method addition and removal.
+ * new feature: SB-EXT:ATOMIC-INCF allows atomic incrementation of
+ appropriately typed structure slots without locking.
+ * new feature: SB-EXT:CALL-WITH-TIMING provides access to timing
+ information like those gathered by TIME using a programming-friendly
+ interface.
+ * new feature: TIME reports time taken even if the form performs a
+ non-local transfer of control.
+ * enhancement: reduced conservativism on GENCGC platforms: on
+ average 45% less pages pinned (measured from SBCL self build).
+ * bug fix: SB-EXT:COMPARE-AND-SWAP on SYMBOL-VALUE can no longer
+ mutate constant symbols or violate declaimed type of the symbol.
+ * bug fix: SB-THREAD:SIGNAL-SEMAPHORE could fail to wakeup threads
+ sleeping on the semaphore in heavily contested semaphores.
+ * bug fix: semaphores and condition variables were not interrupt
+ safe.
+ * bug fix: SB-THREAD:CONDITION-WAIT doesn't allow waits on mutexes
+ owned by other threads anymore.
+ * bug fix: FIND on lists called KEY outside the specified
+ subsequence. (reported by budden)
+ * bug fix: LOG doesn't use single-float intermediate results when
+ given mixed integer and double-float arguments, leading to better
+ precision. (reported by Bob Felts)
+ * bug fix: LOG with base zero returned values of inconsistent type.
+
+changes in sbcl-1.0.20 relative to 1.0.19:
+ * minor incompatible change: OPTIMIZE qualities
+ SB-C::STACK-ALLOCATE-DYNAMIC-EXTENT, SB-C::STACK-ALLOCATE-VECTOR,
+ and SB-C::STACK-ALLOCATE-VALUE-CELLS no longer exist. See documentation
+ and SB-EXT:*STACK-ALLOCATE-DYNAMIC-EXTENT* for details.
+ * documentation: some slot access efficiency guidelines have been
+ added to the user manual.
+ * optimization: ASSOC-IF, ASSOC-IF-NOT, MEMBER-IF, MEMBER-IF-NOT,
+ RASSOC, RASSOC-IF, and RASSOC-IF-NOT are now equally efficient
+ as ASSOC and MEMEBER.
+ * optimization: calls to ASSOC, MEMBER, and RASSOC can be transformed
+ to more efficient EQ-comparison versions more often.
+ * optimization: enhanced derivation of DOLIST iteration variable type
+ for constant lists.
+ * optimization: constant folding of simple (LIST ...) forms as DOLIST
+ arguments.
+ * optimization: runtime lookup of function definitions can be
+ elided in more cases, eg: (let ((x 'foo)) (funcall foo)).
+ * optimization: compiler is able to derive the return type of
+ (AREF (THE STRING X) Y) as being CHARACTER.

+ Gasparovic)
+ * bug fix: bogus odd-number-of-keywords STYLE-WARNINGs from calls to
+ functions with an odd number of &OPTIONAL arguments, a &REST
+ argument, and one or more &KEY arguments at the call site.
+ * bug fix: STYLE-WARNINGs for functions with both &OPTIONAL and &KEY
+ arguments appeared at call sites as well.
+ * bug fix: fixed #425; CLOSE drops input buffers from streams, so
+ READ-LINE &co can no longer read from them afterwards. (reported
+ by Damien Cassou)
+ * 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)

+ 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.

+ test function no longer causes infinite recursion. (reported by
+ Michael Weber)
+ * bug fix: calling SB-COVER:REPORT with a non-directory pathname now

+ correctly. (thanks to Michael Weber)
+
+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.
in normal SPEED policies.
* optimization: NCONC no longer needs to heap cons its &REST list
in normal SPEED policies.
- * 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: 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
2.18.50.0.4 support. (thanks to Marijn Schouten)
