151 The list above is almost certainly incomplete as it is automatically
152 generated from version control history. In particular, it does not include
153 the names of the (very much appreciated) contributors who reported issues to
154 the Perl bug tracker.
156 Many of the changes included in this version originated in the CPAN modules
157 included in Perl's core. We're grateful to the entire CPAN community for
158 helping Perl to flourish.
