+changes in sbcl-0.8.21 (0.9alpha.1?) relative to sbcl-0.8.20:
+ * internal entry point details and argument counts no longer appear
+ in backtraces unless explicitly requested by setting
+ SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS*.
+ * built-in and standard functions no longer have names like "top
+ level local call to FOO".
+ * fixed bug 32: functions defined in non-null lexical environments
+ now have more legible printed representation
+ * fixed bug 33: functions defined in non-null lexical environemnts
+ are now more amenable to inspection by INSPECT.
+ * workaround for bug 354: XEPs no longer appear in backtraces unless
+ explicitly requested.
+ * fixed bug: COUNT and EQUAL no longer issue compiler efficiency
+ notes when operating on objects known to be SIMPLE-BIT-VECTORs.
+ (reported by Lutz Euler)
+ * fixed bug: (TYPEP X '(MEMBER ...)) no longer returns a list in
+ compiled code. (reported by Paul Dietz)
+ * contrib improvement: the SB-SIMPLE-STREAMS contrib now defines
+ STRING-SIMPLE-STREAM and FILE-SIMPLE-STREAM as subclasses of
+ STRING-STREAM and FILE-STREAM, respectively.

changes in sbcl-0.8.20 (0.9alpha.0?) relative to sbcl-0.8.19:
+ * fixed inspection of specialized arrays. (thanks to Simon Alexander)
* fixed disassembly of SHLD and SHRD on x86. (thanks to David
Lichteblau)
+ * fixed loading of multiply forward-referenced layouts.
+ (thanks to Cheuksan Wang)
+ * fixed bug 7: less verbose COMPILE-FILE output. Additionally, the
+ output is now directed to *STANDARD-OUTPUT* as specified by ANSI.
+ (see COMPILE-FILE documentation for details of :PRINT option)
* fixed bugs 19 and 317: fixed-format floating point printing is
more accurate. This also fixes a bug reported by Adam Warner
related to the ~@F format directive.
+ * fixed bug 371: bignum print/read inconsistency. (thanks to Harald
+ Hanche-Olsen)
* fixed bug: SET-SYNTAX-FROM-CHAR correctly shallow-copies a
dispatch table if the from-char is a dispatch macro character.
* fixed bug: COUNT and EQUAL on bit vectors with lengths divisible
by the wordsize no longer ignore the last word. (reported by Lutz
Euler)
+ * fixed bug in type checking of dynamic-extent variables. (reported
+ by Svein Ove Aas)
* optimization: sequence traversal functions use their freedom to
coerce function designators to functions.
* optimization: code with many calls to CLOS methods specialized on
CLOS classes has had redundant type checks removed.
+ * optimization: added declarations to speed up operations that access
+ the internal character database (for example STRING-UPCASE)
+ * optimization: comparison operations between floats and sufficiently small
+ fixnums no longer create extra rationals
* fixed some bugs related to Unicode integration:
** portions of multibyte characters at the end of buffers for
character-based file input are correctly transferred to the
";" and "#|") are more forgiving to encoding errors; they will
STYLE-WARN and then attempt to resync the stream at a character
boundary. (thanks to Teemu Kalvas)
+ * fixed some bugs in the x86-64 port:
+ ** Negative short int return values from c-calls are sign-extended
+ correctly.
+ ** The stack is aligned to 16-bytes for c-calls, as required by
+ the ABI. (thanks to Cheuksan Wang)
+ ** The disassembler understands more x86-64. (thanks to Cheuksan Wang)
+ ** The regression tests use SB-ALIEN:INT instead of SB-ALIEN:INTEGER
+ for enums. (thanks to Vincent Arkesteijn)
+ ** Multiple small optimizations and bugfixes for floating point
+ operations.
* fixed some bugs revealed by Paul Dietz' test suite:
** Space, Tab, Linefeed, Return and Page have the invalid
secondary constituent character trait.
** SET-SYNTAX-FROM-CHAR correctly copies multiple-escape character
syntax.
+ ** WITH-INPUT-FROM-STRING should only update the index place on
+ normal termination.
+ ** Pretty-printing backquoted forms when *PRINT-CIRCLE* is true
+ works more reliably.
+ ** Bit-array operations (BIT-AND and similar) worked incorrectly
+ with one-dimensional arrays with fill pointers.
+ ** TYPE-OF failed on a complex with an integer realpart and a
+ RATIO imagpart.
+ ** compiler failure during type inference for the code of form
+ (IF (EQL X (THE ...)) ...) (MISC.535).
changes in sbcl-0.8.19 relative to sbcl-0.8.18:
* new port: SBCL now works in native 64-bit mode on x86-64/Linux
