additional payload (to reduce problems with lifetime of objects) and are delivered to one or more event sinks. This is more powerful and reduces the complex dependencies between control mode and hooks. Events are now used for hooks, control mode notifications and for monitors (set-hook -B). wait-for can now wait for an event to fire (-E flag, with -F to for filter), with -v to print the payload, as well as listing (-l) waiting clients on an event and forcing one to wake (-w). A few additional hooks are also now available (pane-created, pane-resized, etc) and some of the existing ones have additional format variables available.
