=head1 NAME
[ this is a template for a new perldelta file. Any text flagged as XXX needs
to be processed before release. ]
perl5250delta - what is new for perl v5.25.0
=head1 DESCRIPTION
This document describes differences between the 5.24.0 release and the 5.25.0
release.
=head1 Known Problems
=over 4
=item *
Some modules have been broken by the L<context stack rework|/Internal Changes>.
These modules were relying on non-guaranteed implementation details in perl.
Their maintainers have been informed, and should contact perl5-porters for
advice if needed. Below is a subset of these modules:
=over 4
=item L<Algorithm::Permute>
=item L<Coro>
L<Coro> and perl v5.22.0 were already incompatible due to a change in the perl,
and the reworking on the perl context stack creates a further incompatibility.
perl5-porters has L<discussed the issue on the mailing
list|http://www.nntp.perl.org/group/perl.perl5.porters/2016/05/msg236174.html>.
=item L<Data::Alias>
=item L<RPerl>
=item L<Scope::Upper>
=item L<TryCatch>
=back
=item *
The module L<lexical::underscore> no longer works on perl v5.24.0, because perl
no longer has a lexical C<$_>!
=item *
C<mod_perl> has been patched for compatibility for v5.22.0 and later but no
release has been made. The relevant patch (and other changes) can be found in
their source code repository, L<mirrored at
GitHub|https://github.com/apache/mod_perl/commit/82827132efd3c2e25cc413c85af61bb63375da6e>.

perl Porting/acknowledgements.pl v5.24.0..HEAD
=head1 Reporting Bugs
If you find what you think is a bug, you might check the articles recently
posted to the comp.lang.perl.misc newsgroup and the perl bug database at
L<https://rt.perl.org/> . There may also be information at
L<http://www.perl.org/> , the Perl Home Page.
If you believe you have an unreported bug, please run the L<perlbug> program
included with your release. Be sure to trim your bug down to a tiny but
sufficient test case. Your bug report, along with the output of C<perl -V>,
will be sent off to perlbug@perl.org to be analysed by the Perl porting team.
If the bug you are reporting has security implications which make it
inappropriate to send to a publicly archived mailing list, then see
L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION>
for details of how to report the issue.
