XXX Any important notices here
+=head1 Core Enhancements
+
+XXX New core language features go here. Summarize user-visible core language
+enhancements. Particularly prominent performance optimisations could go
+here, but most should go in the L</Performance Enhancements> section.

+
+XXX Any security-related notices go here. In particular, any security
+vulnerabilities closed should be noted here rather than in the

=head1 Incompatible Changes
XXX For a release on a stable branch, this section aspires to be:
- There are no changes intentionally incompatible with 5.XXX.XXX. If any
- exist, they are bugs and reports are welcome.
+ There are no changes intentionally incompatible with 5.XXX.XXX
+ If any exist, they are bugs, and we request that you submit a
