   [5]release announcement.

   Dave Mitchell provides grant #2 reports #123 and #124 available [6]her=

   Tony Cook provides grant 7's [8]3rd and [9]4th.

   More from Tony Cook, a [10]summary of the March grant work.

Proposed patches

   Jim Keenan provides a patch for [30]Perl #127391 in order to move forw=
ard
   with the documentation issue.

   John Lightsey provided a patch in [31]Perl #127923 to add blacklist an=
d
   whitelist functionality to [32]Locale::Maketext.

   Jerry D. Hedden provided patches to upgrade [33]threads to 2.06,
   [34]Thread::Queue to 3.08, and [35]threads::shared to 1.51.

   Yves Orton provided a patch for [36]Perl #123562, a problem with regul=
ar
   expressions possibly hanging on CPU 100%, which is considered a securi=
ty
   problem.

   Aaron Crane provided a patch for [37]RT #100183, but since 5.24 is
already
   at RC releases, it is frozen and the patch will get in on version 5.25=
.
   You can read Aaron's comment [38]here.

   Matthew Horsfall [39]provided a patch relating to [40]Perl #126579,
   warnings about newlines in open.

   Matthew Horsfall also [41]provided a patch for [42]Perl #124050,
   t/harness.t can mistakenly run tests outside the perl source tree.

   Aristotle Pagaltzis [43]provided a patch to clean up
[44]Module::CoreList.

   Aristotle also provided a patch to fix [45]Perl #127981.

Discussion

   Todd Rinaldo raised RT#127810 to provide a -Dfortify_inc Configure opt=
ion
   to control the current directory appearing in @INC. The conversation
   around it [46]continued [47]further.

   Zefram provides a detailed [48]explaination about an observation made =
by
   Slaven Rezi=C4=87 in [49]Perl #127909.

   Sisyphus [50]raised a confusing bit of documentation, which was fixed =
and
   backported to 5.22.

   Sisyphus also [51]asks about the binary name expected for make.exe.
Bulk88
   explains that it is easier to have it called gmake.exe to know what
   options it supports, and Leon Timmermans suggests it is possible to
   address it.

   Dave Mitchell [52]discussed his work on [53]Scope::Upper. It seems Dav=
e
   was able to get most of it working, but due to how the module works, D=
ave
   does not believe any sensible API can be shield the module from breaka=
ge.
   The discussion continued on extracting the most useful bits into a
   different module.

   Maxwell Carey [54]asks what could cause a problem described on Stack
   Overflow with a failure to print.

   In an email to the list, Sisyphus [55]asks about the current state of
   [56]ExtUtils::MakeMaker with relation to the current version in blead =
vs.
   CPAN.

   The conversation about changing how the signatures feature worked with
   relation to @_ started by Dave Mitchell continues. Ricardo Signes
   [57]provided a summary of Zefram's position and his conclusions.

   Karl Williamson [58]suggests POSIX::set_locale refusing to switch to a
   locale we know will cause a libc crash.

   Smylers [59]asks in [60]Perl #122551 whether [61]Term::ReadLine
should not
   use [62]Term::ReadLine::Perl as the default.

   The conversation in [63]Perl #127232 continues. You can read more
   [64]here.

   Ren=C3=A9e Baecker [65]mentions that perllol still reflects autoderef,=
 which
   was removed, and should be updated.

   Ed Avis suggested in [66]Perl #127993 to add version control conflict
   markers, so Perl could warn you correctly when you forgot merge confli=
ct
   markers in your code.
