-XXX
+Pod::Parser has been removed from the core distribution.
+It still is available for download from CPAN. This resolves [perl
+#119439].

=item *
-XXX
+L<eval_pv()|perlapi/eval_pv> no longer stringifies the exception when
+C<croak_on_error> is true. [perl #134175]
=back
=item *
-C<sort SUBNAME> within an C<eval EXPR> when C<EXPR> was UTF-8 upgraded
-could panic if the C<SUBNAME> was non-ASCII. [perl #134061]
+close() on a pipe now preemptively clears the PerlIO object from the
+IO SV. This prevents a second attempt to close the already closed
+PerlIO object if a signal handler calls die() or exit() while close()
+is waiting for the child process to complete. [perl #122112]
+
+=item *
+
+C<< sprintf("%.*a", -10000, $x) >> would cause a buffer overflow due
+to mishandling of the negative precision value. [perl #134008]
+
+=item *
+
+scalar() on a reference could cause an erroneous assertion failure
+during compilation. [perl #134045]
=item *
-Correctly handle realloc() modifying C<errno> on success so that the
-modification isn't visible to the perl user, since realloc() is called
-implicitly by the interpreter. This modification is permitted by the
-C standard, but has only been observed on FreeBSD 13.0-CURRENT. [perl
-#133958]
+Extraordinarily large (over 2GB) floating point format widths could
+cause an integer overflow in the underlying call to snprintf(),
+resulting in an assertion. Formatted floating point widths are now
+limited to the range of int, the return value of snprintf(). [perl
+#133913]
