Add : You can use a function name as a callback by passing a string reference to wizard() instead of a code reference.
Fix : Compatiblity with perl 5.11.1 and 5.11.2.
Fix : Scalars stored into the data slot no longer leak.
Fix : Thread destruction should not segfault anymore.
Opt : As a result of removing the deprecated features, less memory is used for both threaded (a pointer table is used instead of a hash) and non-threaded (no global structure is needed anymore) perls.
Rem : As advertised in the precendent version, all the signature related features were removed. This includes the 'sig' option to wizard(), the getsig() and gensig() functions, and the SIG_* constants.
