That's my recollection as well. The "Previously" does not refer to 9.6,
but to that commit.

There is small change of behavior coming as a by-product of the
introduction of /if.../endif blocks.

When doing in 9.x:

select '1st buffer' \g
followed by \e
and editing with select '2nd buffer' (without ending the query)
and then back in psql doing '\r' and '\p', the result is
select '2nd buffer'

The same with v10 leads instead to
select '1st buffer'

I'm not sure whether it's above the level of detail worth being mentioned
in the release notes.
