+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.
+  * 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.
+  * bug fix: restart computation during the execution of a restart
+    test function no longer causes infinite recursion. (reported by
+    Michael Weber)
+  * bug fix: calling SB-COVER:REPORT with a non-directory pathname now
+    signals an error. (thanks to Pierre Mai)
+  * bug fix: EXPORT left symbol unexported in conflict situations.
+    (thanks to Michael Weber)
+  * bug fix: correctly handle name conflicts involving CL:NIL.
+    (thanks to Michael Weber)
+  * bug fix: RESOLVE-CONFLICT restart for name conflicts handles
+    conflicts arising from USEing package with conflicting symbols
+    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)
