New Platforms


Perl now compiles under NetBSD on VAX machines. However, it's not possible for that platform to implement floating-point infinities and NaNs compatibly with most modern systems, which implement the IEEE-754 floating point standard. The hexadecimal floating point (0x...p[+-]n literals, printf %a) is not implemented, either. The make test passes 98% of tests.

Internal Changes ^

Selected Bug Fixes ^

Acknowledgements ^

Perl 5.25.6 represents approximately 4 weeks of development since Perl 5.25.5 and contains approximately 16,000 lines of changes across 300 files from 23 authors.

Excluding auto-generated files, documentation and release tools, there were approximately 10,000 lines of changes to 190 .pm, .t, .c and .h files.

Perl continues to flourish into its third decade thanks to a vibrant community of users and developers. The following people are known to have contributed the improvements that became Perl 5.25.6:

Aaron Crane, Andy Lester, Chris 'BinGOs' Williams, Dagfinn Ilmari Mannsåker, Dan Collins, David Mitchell, François Perrad, Hugo van der Sanden, James E Keenan, James Raspass, Jarkko Hietaniemi, Karl Williamson, Lukas Mai, Nicolas R., Reini Urban, Sawyer X, Sergey Aleynikov, Stevan Little, Steve Hay, Steven Humphrey, Thomas Sibley, Tony Cook, Yves Orton.

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.

For a more complete list of all of Perl's historical contributors, please see the AUTHORS file in the Perl source distribution.

Reporting Bugs ^

If you find what you think is a bug, you might check the perl bug database at https://rt.perl.org/ . There may also be information at http://www.perl.org/ , the Perl Home Page.

If you believe you have an unreported bug, please run the 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 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 "SECURITY VULNERABILITY CONTACT INFORMATION" in perlsec for details of how to report the issue.
