docs(changelog): update for v2.13.3

Default of 1 serializes every hub call on a connection - a slow one
(GetTicketProjects hitting an unreachable ticket system, 10s timeout)
blocked unrelated calls like UpdateList/UpdateListConfig behind it for
the same duration, making list-settings save appear to hang.
