July 6th-12th
News and updates
Salvatore Bonaccorso [1]reported a security issue in [2]XSLoader to
receive a proper CVE ID for it. The fix was already committed in perl.
Father Chrysostomos [3]notifies he created a branch with work to finally
remove the deprecated ${^ENCODING} functionality and makes
[4]encoding die
when its invocation would use that functionality. It also recommends
[5]Filter::Encoding as an alternative.

Dave Mitchell provided the Grant #2 report for [6]June and [7]reports

Proposed patches
Tony Cook provides a patch in [51]Perl #128564 to increase
parallelization
for GNU make builds on Win32.
Dan Collins provides a patch in [52]Perl #30807 to change the text of two
messages to propose that the data might also be corrupt or not a
[53]Storable binary image.
Dan Collins also provides a patch in [54]Perl #33156 to fix a core API
documentation problem.
Father Chrysostomos provides a patch in [55]Perl #128588 to properly
handle tied hashes for references to references in ref calls.
Graham Knop [56]provided a patch to fix warnings in [57]Data::Dumper test
on old perl.
Tony Cook provided a patch for [58]Perl #128524 ([59]Data::Dumper gets
string lengths wrong when the utf8 flag is set).
Discussion
Karl Williamson [60]started a very interesting discussion on a possible
security-related use of Unicode. Since different scripts might have
characters that look similar, it is possible to provide a different
Unicode script of a similar-looking character as part of a string, thus
mixing the Unicode scripts. Karl suggests adding a feature to regular
expression to check for same-script string ("script-run"). The discussion
takes place on the best syntax for it in regular expressions.
Dave Mitchell [61]summerized the possible solutions for the /$empty/
issue, with a new suggestion on how to approach it.
Maxwell Carey [62]asked how to access %^H from XS. Zefram [63]provided a
thorough explanation.
