+L<XXX> has been upgraded from version A.xx to B.yy.
-Regular expressions objects weren't properly counted for object id
-purposes on retrieve. This would corrupt the resulting structure, or
-cause a runtime error in some cases. [perl #134179]

+C<\N{} here is restricted to one character> is now emitted in the same
+circumstances where previously C<\N{} in inverted character class or as
+a range end-point is restricted to one character> was.

+This is due to new circumstances having been added in perl v5.30 that
+weren't covered by the earlier wording.

+The C<ECHO> macro is now defined. This is used in a C<dtrace> rule
+that was originally changed for FreeBSD, and the FreeBSD make
+apparently predefines it. The Solaris make does not predefine C<ECHO>
+which broke this rule on Solaris. [perl #134218]

-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]
+The PERL_DESTRUCT_LEVEL environment variable was formerly only honored on
+perl binaries built with DEBUGGING support. It is now checked on all perl
+builds. Its normal use is to force perl to individually free every block
+of memory which it has allocated before exiting, which is useful when
+using automated leak detection tools such as valgrind.
=item *
-C<< sprintf("%.*a", -10000, $x) >> would cause a buffer overflow due
-to mishandling of the negative precision value. [perl #134008]
+The API eval_sv() now accepts a C<G_RETHROW> flag. If this flag is
+set and an exception is thrown while compiling or executing the
+supplied code, it will be rethrown, and eval_sv() will not return.

+As part of the fix for [perl #2754] perl_parse() now returns non-zero
+if exit(0) is called in a C<BEGIN>, C<UNITCHECK> or C<CHECK> block.
-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

+Parsing incomplete hex or binary literals was changed in 5.31.1 to
+treat such a literal as just the 0, leaving the following C<x> or C<b>
+to be parsed as part of the next token. This could lead to some
+silent changes in behaviour, so now incomplete hex or binary literals
+produce a fatal error. [perl #134125]

-Incomplete hex and binary literals like C<0x> and C<0b> are now
-treated as if the C<x> or C<b> is part of the next token. [perl

+eval_pv()'s I<croak_on_error> flag will now throw even if the

-A spurious C<)> in a subparse, such as in C<s/.../code here/e> or
-C<"...${code here}">, no longer confuses the parser.
-
-Previously a subparse was bracketed with generated C<(> and C<)>
-tokens, so a spurious C<)> would close the construct without doing the
-normal subparse clean up, confusing the parser and possible causing an
-assertion failure.
-
-Such constructs are now surrounded by artificial tokens that can't be
-included in the source. [perl #130585]
+C<INIT> blocks and the program itself are no longer run if exit(0) is
+called within a C<BEGIN>, C<UNITCHECK> or C<CHECK> block. [perl

-Reference assignment of a sub, such as C<\&foo = \&bar;>, silently did
-nothing in the C<main::> package. [perl #134072]
