Hi all, The following patches were applied to serialization in CVS (not yet the release): 1 bugfix: serialization of an empty string is <string></string> but deserialization of that XML construct was NIL which is not a string we now return an empty string in that case thanks to randall randall 2 added serializable-slots implementation for sbcl thanks to Anthony W. Juckel 3 added code to deal with unbound slots when serializing (noted by anthony juckel) and code to deal with missing slots when deserializing 4 added reset-class-slots 5 now testing xml and sexp serialization seperately, added empty string test thanks to randall randall Sven
