WoWInterface - 2.4 Changes to the combat log

So I haven't been able to get a character copied onto the PTR so I'm still a bit at a loss as to how the combat log changes affect mods as of yet.

Previously, for my mod RedAlert, I was registering events such as "CHAT_MSG_SPELL_PERIODIC_SELF_BUFFS" and then:

if (strfind(msg,"You gain Buff Name.") ) then
do something
end

Is the general functionality of this still applicable? From what I can tell the event names are changing...

http://www.wowwiki.com/COMBAT_LOG_EVENT_Details has the info on the Combat log event but I want to make sure I follow the changes...

From what I can tell, "CHAT_MSG_SPELL_PERIODIC_SELF_BUFFS" will become "SPELL_AURA_APPLIED_BUFF"

Am I right?

If anyone is able to shed some light on this I'd appreciate it unitl I can get onto the PTR and experiment some myself.
