+ * minor incompatible change: parsing of namestrings on a physical
+ (Unix) host has changed; numbers after the final #\. in a
+ namestring are no longer interpreted as a version field. This is
+ intented to be largely invisible to the user, except that the
+ meaning of the namestring "*.*.*" has changed: it now refers to a
+ pathname with :TYPE :WILD :NAME #<pattern "*.*">. This namestring
+ should usually be replaced by
+ (make-pathname :name :wild :type :wild :version :wild)
+ with the added benefit that this is more likely to be portable.
+ As a consequence of this change, the :IF-EXISTS :NEW-VERSION
+ option to OPEN now signals an error if the file being opened
+ exists; this may have an impact on existing code.
