72       Perl 5.30.2 represents approximately 4 months of development since Perl
73       5.30.1 and contains approximately 2,100 lines of changes across 110
74       files from 15 authors.

79       Perl continues to flourish into its fourth decade thanks to a vibrant
80       community of users and developers.  The following people are known to
81       have contributed the improvements that became Perl 5.30.2:
82
83       Chris 'BinGOs' Williams, Dan Book, David Mitchell, Hugo van der Sanden,
84       Karen Etheridge, Karl Williamson, Matthew Horsfall, Nicolas R., Petr
85       Písař, Renee Baecker, Sawyer X, Steve Hay, Tomasz Konojacki, Tony Cook,

88       The list above is almost certainly incomplete as it is automatically
89       generated from version control history.  In particular, it does not
90       include the names of the (very much appreciated) contributors who
91       reported issues to the Perl bug tracker.
92
93       Many of the changes included in this version originated in the CPAN
94       modules included in Perl's core.  We're grateful to the entire CPAN
95       community for helping Perl to flourish.
