changes. The numbers refer to the Perl repository change
numbers; see Changes58 (or Changes in Perl 5.8.1). In addi-
tion to these changes, lots of work took place in integrat-
ing threads, PerlIO, and Unicode; general code cleanup; and
last but not least porting to non-UNIX lands such as Win32,
VMS, Cygwin, DJGPP, VOS, MacOS Classic, and EBCDIC.
