I found that there isn't an item that referring the following commit:

commit 547f04e7348b6ed992bd4a197d39661fe7c25097
Author: Thomas Munro <tmunro@postgresql.org>

    pgbench: Improve time logic.
    
    Instead of instr_time (struct timespec) and the INSTR_XXX macros,
    introduce pg_time_usec_t and use integer arithmetic.  Don't include the
    connection time in TPS unless using -C mode, but report it separately.

This commit changed the output results that are visible for users, that is,
tps with "including connection establishing" and "excluding ..." are no
longer reported, so I wonder we should let users know it.

Another user-visible change on pgbench that is not listed in the release
notes is the support for pipeline mode. There is a mention about libpq
supporting pipeline, so I think we can also mention that of pgbench.

There are other minor improvement on pgbench, but pgbench is just a
benchnark tool and its changes do not directly affect to user application,
so maybe we don't have to describe all in the release notes.
