| 16 | =head1 Changes |
| 17 | |
| 18 | This is just a selected list of some of the more notable changes. |
| 19 | The numbers refer to the Perl repository change numbers; see |
| 20 | L<Changes58> (or L<Changes> in Perl 5.8.1). In addition to these |
| 21 | changes, lots of work took place in integrating threads, PerlIO, and |
| 22 | Unicode; general code cleanup; and last but not least porting to |
| 23 | non-Unix lands such as Win32, VMS, Cygwin, DJGPP, VOS, MacOS Classic, |
| 24 | and EBCDIC. |
