+The logic for parsing, merging, and dumping XS typemaps has been extracted
+from C<ExtUtils::ParseXS> into a module of its own, L<ExtUtils::Typemaps>.
+C<ExtUtils::Typemaps> offers an interface to typemap handling outside of
+the scope of the XS compiler itself.
+
+As a first use case of the improved API and extensibility, typemaps can now
+be included inline in XS code with a HEREDOC-like syntax:
+
+ TYPEMAP: <<END_TYPEMAP
+ MyType T_IV
+ END_TYPEMAP

-XXX Describe change here
+The L<Invalid version format|perldiag/"Invalid version format (%s)">
+error message now says "negative version number" within the parentheses,
+rather than "non-numeric data", for negative numbers.

+
+The two warnings
+L<Possible attempt to put comments in qw() list|perldiag/"Possible attempt to put comments in qw() list">
+and
+L<Possible attempt to separate words with commas|perldiag/"Possible attempt to separate words with commas">
+are no longer mutually exclusive: the same C<qw> construct may produce
+both.
+
+=item *
+
+Warnings that mention the names of lexical (C<my>) variables with Unicode
+characters in them now respect the presence or absence of the C<:utf8>
+layer on the output handle, instead of outputting UTF8 regardless. Also,
+the correct names are included in the strings passed to C<$SIG{__WARN__}>
+handlers, rather than the raw UTF8 bytes.

+C<when> blocks are now capable of returning variables declared inside the
+enclosing C<given> block [perl #93548].
+
+=item *
+
+A problem with context propagation when a C<do> block is an argument to
+C<return> has been fixed. It used to cause undefined to be returned in
+some cases of a C<return> inside an C<if> block which itself is followed by
+another C<return>.

+Calling C<index> with a tainted constant no longer causes constants in
+subsequently compiled code to become tainted [perl #64804].

The C<SvIsCOW> C macro now returns false for read-only copies of typeglobs,
such as those created by:
