The list above is almost certainly incomplete as it is automatically generated from version control history.  In particular, it does not include the names of the (very much appreciated) contributors who reported issues to the Perl bug tracker.

Many of the changes included in this version originated in the CPAN modules included in Perl's core.  We're grateful to the entire CPAN community for helping Perl to flourish.

Reporting Bugs

If you find what you think is a bug, you might check the perl bug database at <>.  There may also be information at <>, the Perl Home Page.

If you believe you have an unreported bug, please open an issue at <>.  Be sure to trim your bug down to a tiny but sufficient test case.
