+ * new feature: the SB-EXT:MUFFLE-CONDITIONS declaration should be
+ used to control emission of compiler diagnostics, rather than the
+ SB-EXT:INHIBIT-WARNINGS OPTIMIZE quality. See the manual for
+ documentation on this feature. The SB-EXT:INHIBIT-WARNINGS
+ quality should be considered deprecated.
+ * fixed bug: DEFCLASS slot definitions with identical :READER and
+ :WRITER names now signal a reasonable error. (reported by Thomas
+ Burdick)
+ * fixed bug: CLOSE :ABORT T on appending stream no longer causes
+ file deletion.
+ * fixed bug: Invalid slot specification errors now print correctly.
+ (thanks to Zach Beane)
+ * fixed bug 320: Shared to local slot value transfers in class
+ redefinitions now happen corrently from superclasses as
+ well. (reported by Bruno Haible)
