I think the above does not belong to the release notes for 2.3. It would have
been appropriate for the 2.2 release notes. IMO, this has to go in the docs.

The above might be useful information and thus is Ok.

This is true since 2.2, so this does not belong to the release notes for
2.3 and is better explained in the docs.

I find the above so technical to be not understood by the vast majority
of users. Moreover, the chance that someone used ZWSP to achieve that
effect is negligible. Better removed from release notes and maybe explained
in a footnote in the docs.
