=head1 NAME

perl573delta - what's new for perl v5.7.3

=head1 DESCRIPTION

This document describes differences between the 5.7.2 release and the
5.7.3 release.  

(To view the differences between the 5.6.0 release and the 5.7.0
release, see L<perl570delta>.  To view the differences between the
5.7.0 release and the 5.7.1 release, see L<perl571delta>.  To view
the differences between the 5.7.1 release and the 5.7.2 release,
see L<perl572delta>.)

=head1 Changes

This is just a selected list of some of the more notable changes.
The numbers refer to the Perl repository change numbers; see
L<Changes58> (or L<Changes> in Perl 5.8.1).  In addition to these
changes, lots of work took place in integrating 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.

recently posted to the comp.lang.perl.misc newsgroup and the perl
bug database at http://bugs.perl.org.  There may also be
