5.27.4 released!
Message ID:
  I like to think (and
  the sooner the better!)
  of a cybernetic meadow
  where mammals and computers
  live together in mutually
  programming harmony
  like pure water
  touching clear sky. 

  I like to think
  (right now, please!)
  of a cybernetic forest
  filled with pines and electronics
  where deer stroll peacefully
  past computers
  as if they were flowers
  with spinning blossoms. 

  I like to think
  (it has to be!)
  of a cybernetic ecology
  where we are free of our labors
  and joined back to nature,
  returned to our mammal
  brothers and sisters,
  and all watched over
  by machines of loving grace.

    -- Richard Brautigan, "All Watched Over By Machines Of Loving Grace"

You can find a full list of changes in the file "perldelta.pod" located in the "pod" directory inside the release and on the web at

Perl 5.27.4 represents approximately 4 weeks of development since Perl 5.27.3 and contains approximately 5,000 lines of changes across 140 files from 18 authors.

Excluding auto-generated files, documentation and release tools, there were approximately 3,300 lines of changes to 76 .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 5.27.4:

Abigail, Chris 'BinGOs' Williams, Dagfinn Ilmari Mannsåker, David Mitchell, Dominic Hargreaves, Father Chrysostomos, H.Merijn Brand, James E Keenan, Jarkko Hietaniemi, John SJ Anderson, Karl Williamson, Lukas Mai, Matthew Horsfall, Neil Bowers, Nicolas R., Steve Hay, 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 F<AUTHORS> file in the Perl source distribution.

We expect to release version 5.27.5 on 2017-10-20. The next major stable release of Perl 5, version 28.0, should appear in May 2018.
