=head1 Documentation
=head2 Changes to Existing Documentation
=head3 L<perlintro>
=over 4
=item *
A number of sentences in L<perlintro> have been simplified,
to make things clearer.
Ambiguities were resolved, related to "special variables".
=back
=head1 Platform Support
The :win32 IO layer has been removed. This experimental replacement for the
:unix layer never reached maturity in its nearly two decades of existence.
=head1 Internal Changes
=over 4
=item *
The API constant formerly named C<G_ARRAY>, indicating list context, has now
been renamed to a more accurate C<G_LIST>. A compatibilty macro C<G_ARRAY> has
been added to allow existing code to work unaffected. New code should be
written using the new constant instead. This is supported by C<Devel::PPPort>
version 3.63.
=back
=head1 Selected Bug Fixes
=over 4
=item *
The flags on the OPTVAL parameter to setsockopt() were previously
checked before magic was called, possibly treating a numeric value as
a packed buffer or vice versa. It also ignored the UTF-8 flag,
potentially treating the internal representation of an upgraded SV as
the bytes to supply to the setsockopt() system call. (github L<#18660|https://github.com/Perl/perl5/issues/18660>)
=item *
Only set IOKp, not IOK on $) and $(.
This was issue L<#18955|https://github.com/Perl/perl5/issues/18955>: This will prevent serializers from serializing these
variables as numbers (which loses the additional groups).
This restores behaviour from 5.16

=head1 Reporting Bugs
If you find what you think is a bug, you might check the perl bug database
at L<https://github.com/Perl/perl5/issues>. There may also be information at
L<http://www.perl.org/>, the Perl Home Page.
If you believe you have an unreported bug, please open an issue at
L<https://github.com/Perl/perl5/issues>. Be sure to trim your bug down to a
tiny but sufficient test case.
If the bug you are reporting has security implications which make it
inappropriate to send to a public issue tracker, then see
L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION>
for details of how to report the issue.
=head1 Give Thanks
If you wish to thank the Perl 5 Porters for the work we had done in Perl 5,
you can do so by running the C<perlthanks> program:
perlthanks
This will send an email to the Perl 5 Porters list with your show of thanks.
