  51 <p>This is just a selected list of some of the more notable changes.
  52 The numbers refer to the Perl repository change numbers; see
  53 <em>Changes58</em> (or <a href="file://C|\msysgit\mingw\html/ext/Data/Dumper/Changes.html">the Changes manpage</a> in Perl 5.8.1).  In addition to these
  54 changes, lots of work took place in integrating threads, PerlIO, and
  55 Unicode; general code cleanup; and last but not least porting to
  56 non-UNIX lands such as Win32, VMS, Cygwin, DJGPP, VOS, MacOS Classic,
  57 and EBCDIC.</p>
