=head1 Notice
=item *
-L<IO> has been upgraded from version 1.40 to 1.41.
+L<XXX> has been upgraded from version A.xx to B.yy.
-The supplied I<TO> is now always honoured on calls to the send()
-method. [perl #133936]
-
-=item *
-
-L<Storable> has been upgraded from version 3.15 to 3.16.
-
-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]
+If there was something important to note about this change, include that here.
=back
=item *
-Pod::Parser has been removed from the core distribution.
-It still is available for download from CPAN. This resolves [perl
-#119439].

Additionally, the following selected changes have been made:

-Advice has been added regarding the usage of C<< Z<> >>.
+XXX Description of the change here

=head2 Discontinued Platforms
+XXX List any platforms that this version of perl no longer compiles on.

-=item Windows CE

-Support for building perl on Windows CE has now been removed.

+C<cc> will be used to populate C<plibpth> if C<cc> is C<clang>. [perl

+=item VMS
+
+C<-Duse64bitint> is now the default on VMS.

=item *
-L<eval_pv()|perlapi/eval_pv> no longer stringifies the exception when
-C<croak_on_error> is true. [perl #134175]
+XXX
=back
=item *
-Setting C<$)> now properly sets supplementary group ids if you have
-the necessary privileges. [perl #134169]
-
-=item *
-
-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 *
-
-C<%{^CAPTURE_ALL}> is now an alias to C<%-> as documented, rather than
-incorrectly an alias for C<%+>. [perl #131867]
-
-=item *
-
-C<%{^CAPTURE}> didn't work if C<@{^CAPTURE}> was mentioned first.
-Similarly for C<%{^CAPTURE_ALL}> and C<@{^CAPTURE_ALL}>, though
-C<@{^CAPTURE_ALL}> currently isn't used. [perl #131193]
-
-=item *
-
-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]

-=item *
-
-Parsing the following constructs within a sub-parse (such as with
-C<"${code here}"> or C<s/.../code here/e>) has changed to match how
-they're parsed normally:
-
-=over
-
-=item *
-
-C<print $fh ...> no longer produces a syntax error.
-
-=item *
-
-Code like C<s/.../ ${time} /e> now properly produces an "Ambiguous use
-of ${time} resolved to $time at ..." warning when warnings are enabled.
-
-=item *
-
-C<@x {"a"}> (with the space) in a sub-parse now properly produces a
-"better written as" warning when warnings are enabled.
-
-=item *
-
-attributes can now be used in a sub-parse.
-
-=back
-
-[perl #133850]
-
-=item *
-
-Incomplete hex and binary literals like C<0x> and C<0b> are now
-treated as if the C<x> or C<b> is part of the next token. [perl
-#134125]
-
-=item *
-
-A spurious C<)> in a subparse, such as in C<s/.../code here/e> or
-C<"...${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]
-
-=item *
-
-Reference assignment of a sub, such as C<\&foo = \&bar;>, silently did
-nothing in the C<main::> package. [perl #134072]
-
-=item *
-
-sv_gets() now recovers better if the target SV is modified by a signal
-handler. [perl #134035]
-
-=item *
-
-C<readline @foo> now evaluates C<@foo> in scalar context. Previously
-it would be evalauted in list context, and since readline() pops only
-one argument from the stack, the stack could underflow, or be left
-with unexpected values on the stack. [perl #133989]
+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]
