19       This is just a selected list of some of the more notable changes.  The
20       numbers refer to the Perl repository change numbers; see Changes58 (or
21       Changes in Perl 5.8.1).  In addition to these changes, lots of work
22       took place in integrating threads, PerlIO, and Unicode; general code
23       cleanup; and last but not least porting to non-Unix lands such as
24       Win32, VMS, Cygwin, DJGPP, VOS, MacOS Classic, and EBCDIC.
