+changes in sbcl-0.8.17 relative to sbcl-0.8.16:
+ * new feature: a build-time option (controlled by the :SB-UNICODE
+ keyword feature, enabled by default) for building the system with
+ support for the entire 21-bit character space defined by the
+ Unicode consortium.
+ * new feature: the system now has rudimentary external-format
+ support; the primary user-visible change at this time is that
+ characters with the high bit set (such as lower-case-e-acute) will
+ print correctly to a terminal in a UTF-8 environment.
+ * minor incompatible change: BASE-CHAR no longer names a class;
+ however, CHARACTER continues to do so, as required by ANSI.
+ * minor incompatible change: SB-DEBUG:*DEBUG-PRINT-FOO* variables
+ are no longer supported, and SB-DEBUG:*DEBUG-PRINT-VARIABLE-ALIST*
+ has been moved to the SB-EXT package (temporarily re-exported from
+ SB-DEBUG).
+ * minor incompatible change: SB-C::*COMPILER-ERROR-PRINT-FOO* variables
+ are no longer supported: use SB-EXT:*COMPILER-PRINT-VARIABLE-ALIST*
+ instead.
+ * fixed bug #308: non-graphic characters now all have names, as
+ required. (reported by Bruno Haible)
+ * bug fix: Cyclic structures and unprintable objects in compiler
+ messages no longer cause errors. (reported by Bruno Haible)
+ * bug fix: READ, READ-PRESERVING-WHITESPACE, READ-DELIMITED-LIST,
+ and READ-FROM-STRING all now return a primary value of NIL if
+ *READ-SUPPRESS* is true. (reported by Bruno Haible for CMUCL)
+ * bug fix: Default value of EOF-ERROR-P in READ-FROM-STRING is true.
+ (reported by Bruno Haible for CMUCL)
+ * bug fix: ERROR now signals a TYPE-ERROR if the arguments to ERROR
+ do not designate a condition. (reported by Bruno Haible for
+ CMUCL)
+ * bug fix: UNINTERN, USE-PACKAGE, IMPORT and EXPORT all signal an
+ SB-EXT:NAME-CONFLICT condition (subtype of PACKAGE-ERROR) in the
+ name conflict situations in CLHS 11.1.1.2.5, and provide a restart
+ permitting resolution in favour of any of the conflicting symbols.
+ (reported by Bruno Haible for CMUCL)
+ * bug fix: EQUAL compiler optimizations is less aggressive on
+ strings which can potentially compare true despite having distinct
+ specialized array element types.
+ * FORMAT compile-time argument count checking has been enhanced.
+ (report from Bruno Haible for CMUCL)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** RENAME-PACKAGE allows all package designators as new package
+ names.
+ ** constraint propagation and lambda variable substitution are
+ more cautious in dealing with partially deleted code.
+ ** compiler sometimes lost reoptimization passes.
+
changes in sbcl-0.8.16 relative to sbcl-0.8.15:
+ * enhancement: saving cores with foreign code loaded is now
+ supported on x86/NetBSD and sparc/Linux in addition to the previously
+ supported platforms.
+ * bug fix: on some platforms repeated installations caused multiple
+ copies of HTML documentation to be installed -- should not happen
+ any more. (reported by Stefan Scholl)
+ * bug fix: parsing self-recursive alien record types multiple times
+ no longer causes infinite recursion. (reported by Thomas F. Burdick,
+ original patch by Helmut Eller for CMUCL)
+ * bug fix: stack-exhaustion detection works now on NetBSD as well.
+ (thanks to Richard Kreuter)
+ * bug fix: defining classes whose accessors are methods on existing
+ generic functions in other (locked) packages no longer signals
+ bogus package lock violations. (reported by François-René Rideau)
+ * bug fix: special variables as DEFMETHOD parameters no longer have
+ associated bogus type declarations. (reported by David Wragg and
+ Bruno Haible)
* bug fix: read-write consistency on streams of element-type
(SIGNED-BYTE N) for N > 32. (reported by Bruno Haible for CMUCL)
+ * bug fix: redefiniton of the only method of a generic function with
+ no DEFGENERIC no longer emits a full WARNING. In addition,
+ redefinition of generic functions with no DEFGENERIC to an
+ incompatible lambda list now signals an error. (thanks to Zach
+ Beane)
+ * bug fix: DEFGENERIC now works even when there's a function of the
+ same name in an enclosing lexical environment. (thanks to Zach
+ Beane)
+ * fixed compiler failure, caused by instrumenting code during
+ IR1-optimization. (Debian bug report #273606 by Gabor Melis)
+ * optimization: added loop analysis and improved register allocation
* fixed some bugs revealed by Paul Dietz' test suite:
** POSITION on displaced vectors with non-zero displacement
returns the right answer.
+ ** (SIMPLE-STRING) is a valid type specifier for sequence
+ creators.
+ ** *PRINT-LEVEL* handling for slotless structures is pedantically
+ correct.
+ ** PPRINT-INDENT accepts a request for an indentation of any REAL.
+ ** PPRINT-TAB (and the FORMAT ~T directive) now indent by the
+ correct amounts.
+ ** The justification version of the FORMAT ~< directive treats
+ non-zero minpad parameter correctly.
