PERL5361DELTA(1)        Perl Programmers Reference Guide       PERL5361DELTA(1)

NAME
       perl5361delta - what is new for perl v5.36.1

DESCRIPTION
       This document describes differences between the 5.36.0 release and the
       5.36.1 release.

       If you are upgrading from an earlier release such as 5.35.0, first read
       perl5360delta, which describes differences between 5.35.0 and 5.36.0.

Incompatible Changes
       There are no changes intentionally incompatible with 5.36.0.  If any
       exist, they are bugs, and we request that you submit a report.  See
       "Reporting Bugs" below.

Modules and Pragmata
   Updated Modules and Pragmata
       •   Module::CoreList  has  been  upgraded  from  version  5.20220520  to
           5.20230423.

Configuration and Compilation
       •   "Configure" probed for the return type of  malloc()  and  free()  by
           testing whether declarations for those functions produced a function
           type  mismatch  with  the  implementation.   On  Solaris, with a C++
           compiler, this check always failed, since  Solaris  instead  imports
           malloc() and free() from "std::" with "using" for C++ builds.  Since
           the  return  types  of malloc() and free() are well defined by the C
           standard, skip probing for them.  "Configure" command-line arguments
           and hints can still override these type in the unlikely case that is
           needed.  [GH #20806 <https://github.com/Perl/perl5/issues/20806>]

Testing
       Tests were added and changed to reflect the other additions and  changes
       in this release.

Selected Bug Fixes
       •   An  eval() as the last statement in a regex code block could trigger
           an interpreter panic; e.g.

               /(?{ ...; eval {....}; })/

           [GH #19680 <https://github.com/Perl/perl5/issues/19680>]

       •   An "eval EXPR" referring to a lexical  sub  defined  in  grandparent
           scope   no  longer  produces  an  assertion  failures.   [GH  #19857
           <https://github.com/Perl/perl5/issues/19857>]

       •   Writing to a magic variables associated  with  the  selected  output
           handle,  $^,  $~,  $=, "$-" and $%, no longer crashes perl if the IO
           object has been cleared from the selected output handle.  [GH #20733
           <https://github.com/Perl/perl5/issues/20733>]

Acknowledgements
       Perl 5.36.1 represents approximately 11 months of development since Perl
       5.36.0 and contains approximately 5,500 lines of changes across 62 files
       from 24 authors.

       Excluding auto-generated files, documentation and release  tools,  there
       were  approximately  1,600  lines  of  changes  to 23 .pm, .t, .c and .h
       files.

       Perl continues to flourish into its fourth decade thanks  to  a  vibrant
       community  of  users  and developers.  The following people are known to
       have contributed the improvements that became Perl 5.36.1:

       Andreas König, Bram, Chris 'BinGOs' Williams, Craig  A.  Berry,  Dagfinn
       Ilmari  Mannsåker, David Mitchell, Elvin Aslanov, Florian Weimer, Graham

       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://github.com/Perl/perl5/issues>.  There may  also  be
       information at <http://www.perl.org/>, the Perl Home Page.

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

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 "perlthanks" program:

           perlthanks

       This will send an email to the Perl 5 Porters list  with  your  show  of
       thanks.
