perl5382delta, which describes differences between 5.38.1 and 5.38.2.
Incompatible Changes
There are no changes intentionally incompatible with 5.38.2. If any
exist, they are bugs, and we request that you submit a report. See
"Reporting Bugs" below.

<https://github.com/Perl/perl5/issues/21751>]
o Module::CoreList has been upgraded from version 5.20231129 to

Testing
Tests were added and changed to reflect the other additions and changes
in this release.
Selected Bug Fixes
o "use 5.36;" or later didn't enable the post parse reporting of Name
"%s::%s" used only once: possible typo warnings when enabling
warnings. [GH #21271 <https://github.com/Perl/perl5/issues/21271>]
o Fixed a crash or assertion when cleaning up a closure that refers
to an outside "our" sub. [GH #21067
<https://github.com/Perl/perl5/issues/21067>]
o Don't clear the integer flag "IOK" from lines in the
"@{"_<$sourcefile"}" array when a "dbstate" op is removed for that
line. This was broken when fixing [GH #19198
<https://github.com/Perl/perl5/issues/19198>]. [GH #21564
<https://github.com/Perl/perl5/issues/21564>]
o Fixed an issue where utf8n_to_uvchr() failed to correctly identify
certain invalid UTF-8 sequences as invalid. Specifically,
sequences that start with continuation bytes or unassigned bytes
could cause unexpected behaviour or a panic. This fix ensures that
such invalid sequences are now properly detected and handled. This
correction also resolves related issues in modules that handle
UTF-8 processing, such as Encode.
o Builds with "-msse" and quadmath on 32-bit x86 systems would crash
with a misaligned access early in the build. [GH #22577
<https://github.com/Perl/perl5/issues/22577>]
o Fixed a bug introduced in Perl 5.34 whereby uninitialized data in
the underlying array of an AV after it has been unshifted and
resized could lead to segmentation faults or other errors depending
on the data. [GH #21235
<https://github.com/Perl/perl5/issues/21235>]
o Fixed an issue where Perl sometimes failed to correctly toggle into
a dot radix locale. [GH #21746
<https://github.com/Perl/perl5/issues/21746>] [GH #22176
<https://github.com/Perl/perl5/issues/22176>]
o Stopped certain syntax errors from provoking core dumps due to a
double free of an OP. [GH #21724
<https://github.com/Perl/perl5/issues/21724>]
o Fixed a double free error or possible memory leak when failing to
compile certain regexps. [GH #21661
<https://github.com/Perl/perl5/issues/21661>]
o Fixed the initialization of Perl's querylocale() emulation so that
the locale is set correctly if the environment specifies a non-C
locale. [GH #21366 <https://github.com/Perl/perl5/issues/21366>]

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.
