=head1 Notice
[ List each incompatible change as a =head2 entry ]
+=head2 Plain "0" string now treated as a number for range operator
+
+Previously a range C< "0" .. "-1" > would produce a range of numeric
+strings from "0" through "99", this now produces an empty list, just
+as C< 0 .. -1 > does.
+
+This was due to a special case that treated strings starting with "0"
+as strings so ranges like C< "00" .. "03" > produced C< "00", "01",
+"02", "03" >, but didn't specially handle the string C<"0">.
+
+[perl #133695]
+
+=head2 C<\K> now disallowed in look-ahead and look-behind assertions
+
+This was disallowed because it causes unexpected behaviour, and no-one
+could define what the desired behaviour was.

-XXX
+A new parser function L<parse_subsignature()|perlapi/parse_subsignature>
+allows a keyword plugin to parse a subroutine signature while C<use feature
+'signatures'> is in effect. This allows custom keywords to implement
+semantics similar to regular C<sub> declarations that include signatures.
+[perl #132474]
+
+=item *
+
+Since on some platforms we need to hold a mutex when temporarily
+switching locales, new macros (C<STORE_LC_NUMERIC_SET_TO_NEEDED_IN>,
+C<WITH_LC_NUMERIC_SET_TO_NEEDED> and C<WITH_LC_NUMERIC_SET_TO_NEEDED_IN>)
+have been added to make it easier to do this safely and efficiently
+as part of [perl #134172].

+C<< $@ = 100; die; >> now correctly propagates the 100 as an exception
+instead of ignoring it. [perl #134291]
+
+=item *
+
+C<< 0 0x@ >> no longer asserts in S_no_op(). [perl #134310]

+
+Exceptions thrown while C<$@> is read-only could result in infinite
+recursion as perl tried to update C<$@>, which throws another
+exception, resulting in a stack overflow. Perl now replaces C<$@>
+with a copy if it's not a simple writable SV. [perl #134266]
