                          December 11th - January 1st

   Happy holidays!

News and Updates

   Perl 5.27.7 is [1]released!

   The new smart match broke a considerable amount of CPAN modules and will
   therefore be reverted.

   Andreas Koenig [2]provided a patch to update [3]CPAN.pm to 2.20-TRIAL.

   Dave Mitchell [4]suggested making PERL_OP_PARENT compulsory in 5.28.0.
   This has since been done.

   Karl Williamson [5]provided a new version of his implementation of script
   runs.

   Is it time to declare string- and number-specific bitwise ops fully
stable
   and enable it in use v5.28? Check [6]Perl #123707.

   Pip Cet [7]provided an explanation of how he uses the SpiderMonkey GC to
   find memory leaks in Perl.

   [8]podlators 4.10 is [9]out.

Suggested Patches

   Marco Fontani provided another patch (which was merged) to resolve
   [149]Perl #116080 (Doc issues for system, exec, qx).

   Karl Williamson [150]wonders (regrepeat()) whether we should introduce an
   optimization for repeating characters on a pattern like (foo)+.

Discussions

   Leon [151]raised the need for a language design process.

   Zefram [152]raised (smartmatch/switch deprecation for 5.28) the topic of
   smart match again with regards to what to deprecate in smart match.

   Karl Williamson [153]suggested two deprecations: literal \v in patterns
   except under /x and /[#]/xx.
