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)
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.
