(Special thanks to Bulk88 for helping with these.)

Updates

   The release of Perl 5.22.1 was postponed to handle and review a few he=
xfp
   bugs which were discovered on release of RC3. Steve Hay's [1]post has =
the
   voting file link.

   [2]Term::ANSIColor 4.04 is released! More information is available in =
the
   [3]announcement.

   [4]podlators (consisting of [5]Pod::Man and [6]Pod::Text) 4.00
   [7]released!

   Soon thereafter, versions 4.01, 4.02, and 4.03 were released as well.

   The Mac OS 10.9 compiler has compilation problems on ithreads builds
since
   Jarkko Hietaniemi introduced a commit that adds [8]clang thread safety
   analysis annotations to the perl source code. With the help of Aaron
   Crane, it was decided to only support this when using a later version =
of
   clang.

Proposed patches

   Bulk88 proposed a revised patch in [30]Perl #126686 (build-time
   parallelness).

   Tony Cook provided a proposed patch for handling unnecessary rebuilds,
   described in [31]Perl #126710.

   Sullivan Beck provided a [32]patch to update [33]Locale::Codes.

   Doug Bell provided a patch in [34]Perl #126821 to mention the use of
$? in
   backticks documentation. This patch had already been merged.

   Achim Gratz provided a patch in [35]Perl #126834 to fix a Cygwin-relat=
ed
   test.

Discussion

   Yves Orton [36]suggests setting SVf_POK, SVf_IOK, and SVf_NOK flags on=
ly
   when on setting and not on conversion. This will allow differentiating
   between what a type is (in a manner of speaking) and how you can use i=
t.
   The suggestion and the responses are an interesting read that detail s=
ome
   of the difficulties in types in dynamic languages.

   Dave Mitchell [37]raised a discussion the semantics of @_ with signatu=
re
   subroutines.

   Hanno B=C3=B6ck [38]noted a possibly unnecessary wrapper script genera=
ted by
   Makefile.SH, but as Andy Dougherty [39]explains, it is not as simple
as it
   looks.

   Dave Mitchell helped debug [40]Perl #126261 and Karl Williamson provid=
es
   more details and is working on a fix.

   Ed Avis is looking at standardizing more documentation and words with
   different spellings and pronounciations. Now looking at regex vs. rege=
xp,
   Ed [41]asks which should be used. Opinions differ, as usual.

   Karl Williamson is [42]noting that Porting/bench.pl does not include
   utf8_heavy.pl in its results.

   Karl also [43]inquired about utf8 support in identifier names.
