you should now be able to bind an event handler to a 
paticiular file or function not just a paticular event
when using the custom event 

like "file:somefile.c"
or "func:somefunc"

also events now have headers which can be added 
with varargs and should be created and delivered with api calls


switch_event *event;

regular event:
if (switch_event_create(&event, SWITCH_EVENT_STARTUP) == SWITCH_STATUS_SUCCESS) {
	switch_event_add_header(event, "event_info", "System Ready");
	switch_event_fire(&event);
}

custom event:
if (switch_event_create_subclass(&event, SWITCH_EVENT_CUSTOM, "some_subclass_string") == SWITCH_STATUS_SUCCESS) {
	switch_event_add_header(event, "event_info", "hello world %d", 42);
	switch_event_fire(&event);
} 

switch_event_add_header(event, "test %d", 42);

also you can serialize and event into a buffer in
a printable/transferrable format with optional body

char buf[1024];

with body:
switch_event_serialize(event, buf, sizeof(buf), "This is a body my favorite number is %d", 42);

no body:
switch_event_serialize(event, buf, sizeof(buf), NULL);
